+<NAME>
+refined_search_strategy
+</NAME>
+
+<DESCRIPTION>
+Optimized the sequence optimization process by:
+1.  Expanding the multi-resolution schedule to start at $n=128$, allowing for faster discovery of the global sequence envelope.
+2.  Refining the dynamic softmax gradient with a more aggressive beta schedule (up to 200) to sharpen focus on convolution peaks during refinement.
+3.  Implementing a "Peak Pressure" move that identifies and multiplicatively reduces the specific sequence elements contributing most to the maximum convolution peaks.
+4.  Adding a more robust "Inverse-weighted Contribution Boost" to selectively increase values that do not contribute to the current convolution maximum.
+5.  Enhancing the symmetry preservation logic to be more deterministic in the final stages of optimization.

+<NAME>
+Super-Sharpened_Surgical_Refinement
+</NAME>
+
+<DESCRIPTION>
+This update introduces several key improvements to push the objective value below the 1.60 threshold:
+1.  **Super-Sharpened Log-Gradient Step**: Replaces the discrete "efficiency-gap" move with a continuous log-space gradient descent using the property $\frac{\partial \ln(2n P / S^2)}{\partial a_i} = 2(\frac{grad_i}{P} - \frac{1}{S})$. This move utilizes a numerically stable softmax with $\beta$ scaling up to 500, surgically targeting the highest peaks of the convolution.
+2.  **Edge-Windowed Power Law Seeding**: Refines the theoretical power-law initializations ($a_n \approx n^{-0.5}$) with a soft taper at the boundary to smooth the convolution drop-off, which is a common characteristic of optimal solutions.
+3.  **Frequency-Selective Spectral Refinement**: Upgrades spectral mutations to damp high-frequency jitter by up to 80% while preserving the global "envelope" discovered at lower resolutions.
+4.  **Adaptive Symmetry Hardening**: Enforces deterministic symmetry with a 98% probability in the final 15% of the search duration, effectively halving the search dimensionality during the critical refinement phase.

+<NAME>surgical_peak_to_gap_optimization</NAME>
+
+<DESCRIPTION>
+This optimization introduces several key improvements to break the 1.60 plateau:
+1.  **Coupled Peak-to-Gap Mass Migration**: Replaces independent reduction and boost moves with a coordinated operation that transfers mass from indices contributing to convolution peaks to those contributing to gaps.
+2.  **Ultra-Sharpened Softmax ($\beta$ up to 500)**: Uses a log-stable softmax with an increased $\beta$ schedule to surgically isolate the exact indices responsible for the convolution maximum.
+3.  **Deterministic Symmetry Hardening**: Once progress exceeds 85%, the search enforces perfect symmetry at every iteration, effectively halving the search space dimensionality during the final refinement phase.
+4.  **Surgical Spectral Damping**: Refines the spectral mutation to specifically damp high-frequency jitter while preserving the low-frequency global envelope.
+5.  **Refined Resolution and Timing**: Skews the time allocation more heavily towards the 768-length refinement for high-resolution exploitation.

+<NAME>
+Surgical_Peak_to_Gap_Migration
+</NAME>
+
+<DESCRIPTION>
+This edit implements several targeted improvements to the optimization loop:
+1.  **Atomic Peak-to-Gap Mass Migration**: Combines peak reduction and efficiency boosting into a single "water-filling" move. This identifies indices contributing most to the convolution peaks (high gradient) and moves their mass to indices that contribute the least, directly flattening the convolution while preserving the sequence sum.
+2.  **Robust High-Beta Softmax**: Increases the maximum beta to 600 while using a log-stabilized weight calculation (`c/max_c - 1.0`) to prevent numerical overflow, allowing for surgical precision in dampening specific convolution peaks.
+3.  **Deterministic Symmetry Hardening**: Increases the pressure on symmetric convergence during the final 15% of the time budget, ensuring the search focuses on refining the symmetric envelope which is theoretically optimal for this problem.
+4.  **Refined Spectral Mutation**: Replaces the blanket high-frequency damping with a more controlled power-law-aware smoothing to preserve the global envelope while suppressing stochastic "jitter".

+<NAME>
+surgical_gradient_refinement
+</NAME>
+
+<DESCRIPTION>
+Refine the optimization process with the following improvements:
+1.  **Surgical Mass Migration**: Replaced the existing relative-gradient move with a higher-precision sensitivity-based migration. This uses a numerically stable Softmax (up to $\beta=500$) to identify the indices contributing most to convolution peaks and redistributes their "mass" to less critical indices, effectively flattening the convolution $L_\infty$ norm.
+2.  **Deterministic Symmetry Hardening**: Increased the pressure on symmetry in the final stages of search, as the optimal sequences for this problem are theoretically symmetric.
+3.  **Numerical Efficiency**: Updated `_normalize_scale` and `_seed_sequence` to use more efficient NumPy methods and refined the power-law seed ranges to focus on the $p=0.5$ region.
+4.  **Targeted Spectral Damping**: Adjusted the low-pass filter to be more aggressive as the search progresses, ensuring the sequence maintains a clean global envelope while avoiding high-frequency noise introduced by stochastic moves.

+<NAME>
+surgical_mass_migration_and_sharpened_sensitivity
+</NAME>
+
+<DESCRIPTION>
+The following refinements are proposed to push the evaluator value toward the theoretical 1.57 limit:
+1. **Multiplicative Sensitivity Gradient**: In both the "Sharpened Softmax" and "Mass Migration" moves, replace the raw gradient with multiplicative sensitivity (`grad * seq`). This identifies indices where a proportional change has the greatest impact on reducing convolution peaks, which is more effective than additive sensitivity for the non-negative sequence constraint.
+2. **Improved Coupled Mass Migration**: Increase the focus on convolution peaks by boosting the $\beta$ parameter for the mass migration move. Use a balanced strategy that takes mass from high-sensitivity indices and redistributes it to low-sensitivity ones, directly flattening the convolution.
+3. **Surgical Step Sizing**: Gradually reduce the number of targeted indices (`t_size`) as the search progresses. This shifts the strategy from broad global shaping to high-precision local refinement in the final $n=768$ stage.
+4. **Enforced Late-Stage Symmetry**: Increase the frequency and determinism of symmetry enforcement in the final 15% of the budget. Since the optimal solution is theoretically symmetric, this effectively halves the search dimensionality at the point of highest resolution.
+5. **Numerical Stability**: Use log-stable softmax weights with a wider range (`clip` to -80) to allow for extremely high $\beta$ (up to 800) during final exploitation.

+Refined_gradient_dynamics_and_symmetry_hardening
+</NAME>
+
+<DESCRIPTION>
+This update focuses on stabilizing the optimization of the coefficient sequence by implementing several key improvements:
+1.  **Resolution-Transition Smoothing**: Adds a small Gaussian-like smoothing kernel after resolution interpolation to prevent high-frequency artifacts from creating "derivative kinks" that mislead the gradient moves.
+2.  **Centered Multi-Point Mass Migration**: Refines the coupled migration move to use a larger pool of potential "low-impact" indices, allowing for more distributed mass redistribution which prevents the sequence from becoming prematurely sparse.
+3.  **Centered Gradient Step**: Modifies the primary gradient move to target indices based on their sensitivity *relative to the mean impact*, providing a more balanced reduction of the convolution peaks while adhering to the constant-sum constraint.
+4.  **Deterministic Symmetry Hardening**: Pulls the threshold for deterministic symmetry enforcement to 75% of the time budget, halving the search dimensionality earlier to focus on refining the symmetric optimal envelope.
+5.  **Targeted Spectral Mutation**: Adjusts spectral mutations to use a power-law-weighted jitter and surgical high-frequency damping, better preserving the global structure identified in earlier multi-res stages.
+6.  **Smoothing Mutation**: Replaces simple local scaling with a TV-like smoothing operation to damp stochastic high-frequency "jitter" introduced by the gradient moves.

+<NAME>
+surgical_gradient_and_mass_migration
+</NAME>
+
+<DESCRIPTION>
+1.  **Refined Seeding**: Updated `_seed_sequence` to include more theoretically sound initial shapes (symmetric power-laws, Beta-like distributions, and windowed power laws) to help the search start closer to the global optimum.
+2.  **Optimized Gradient Move**: Improved the high-beta gradient update by using a more precise relative-gradient formulation that accounts for the softmax volume (`w_sum`). This better approximates the true gradient of the log-objective function.
+3.  **Atomic Mass Migration**: Replaced the independent peak reduction and gap boost with a unified "Atomic Peak-to-Gap Mass Transfer" move. This move identifies the specific indices contributing to convolution peaks (via high-beta softmax) and moves their mass to indices that contribute least to the peaks, preserving the sequence sum and enhancing stability.
+4.  **Log-Stable Selection**: Implemented log-stable weight calculations for both peak and gap selection, preventing numerical overflow and ensuring surgical precision at high resolutions.
+5.  **Enhanced Symmetry Hardening**: Shifted to a more robust symmetry enforcement schedule that favors symmetry more strongly as the search approaches the deadline, especially in the final 8% of the time budget.

+surgical_mass_migration_v2
+</NAME>
+
+<DESCRIPTION>
+This update refines the optimization algorithm with several targeted improvements:
+1.  **Ultra-Sharp Log-Stable Gradient**: Increases the softmax beta to 500 in the final search phase to precisely isolate peak-contributing indices, using log-stability to prevent numerical overflow.
+2.  **Efficient Mutation Loop**: Precomputes the convolution of the current best sequence once per improvement, reducing the number of expensive `np.convolve` operations per iteration from three to one.
+3.  **Atomic Mass Migration**: Implements a "water-filling" move that moves mass from high-gradient (objective-hurting) indices to low-gradient (objective-helping) indices, maintaining the sequence sum naturally.
+4.  **Deterministic Symmetry Hardening**: Halves the search dimensionality in the final 15% of the search budget by enforcing symmetry deterministically, allowing the search to focus on refining the symmetric envelope.
+5.  **Optimized Resolution Scaling**: Focuses computational budget on higher resolutions (256, 512, 768) and increases seeding diversity for power-law candidates.

+<NAME>
+Surgical_Mass_Migration_and_Symmetry_Hardening
+</NAME>
+
+<DESCRIPTION>
+This update implements several key improvements based on expert recommendations:
+1.  **Atomic Peak-to-Gap Mass Migration**: Replaces the independent reduction and boost moves with a unified "water-filling" operation. This move identifies indices with the highest contribution to convolution peaks (using a high-beta gradient proxy) and simultaneously migrates mass to indices that contribute the least, improving stability and objective targeting.
+2.  **Ultra-Sharp Gradient beta**: Increases the maximum $\beta$ from ~150 to 500 in the final search resolution ($n=768$) to precisely isolate and shave off convolution maxima.
+3.  **Deterministic Symmetry Hardening**: Shifts to a more robust symmetry constraint in the final 20% of the search budget, effectively halving the search space dimensionality during the most expensive refinement phase.
+4.  **Optimized Resolution Schedule and Seeding**: Initiates search at $n=128$ to establish a better global envelope before upscaling, and uses a more diverse set of power-law seeds.
+5.  **Performance Efficiency**: Replaces slow list-based evaluations with fast NumPy-based objective calculations within the search loops.

+surgical_gradient_and_mass_migration
+</NAME>
+
+<DESCRIPTION>
+Optimizes the sequence evolution by implementing a more mathematically grounded objective gradient and an 'atomic' mass migration move.
+
+1.  **Objective Gradient Refinement**: Updated the gradient calculation to accurately reflect the derivative of the objective function $f(a) = \frac{2n \cdot \max(a*a)}{(\sum a)^2}$. The relative gradient $G_i \propto \frac{\partial \max(c)}{\partial a_i} - \frac{2 \max(c)}{\sum a}$ is now used to identify indices that contribute disproportionately to the convolution peak versus the total mass.
+2.  **Ultra-Sharpened Beta**: Increased the softmax sharpness parameter $\beta$ to 600 in the final search stages to provide 'Dirac-like' precision in identifying the bottleneck indices in the convolution.
+3.  **Atomic Mass Migration**: Replaced the independent reduction/boost moves with an atomic transfer that moves mass directly from indices with the highest objective gradient to those with the lowest. This preserves the sequence sum and stabilizes convergence.
+4.  **Deterministic Symmetry Hardening**: Implemented a more aggressive symmetry constraint in the final resolution ($n=768$) to halve the search dimensionality and focus on refining the symmetric envelope required for the optimal solution.
+5.  **Adaptive Spectral Mutation**: Refined the spectral mutation to use a frequency-dependent damping ($1/f^2$ like) that preserves the global structure while surgically removing high-frequency 'jitter'.

+<NAME>
+Symmetry_Hardening_and_Atomic_Migration
+</NAME>
+
+<DESCRIPTION>
+Optimized the search by implementing four key improvements:
+1.  **Extended Multi-resolution Schedule**: Added a low-resolution ($n=128$) stage to rapidly discover the global sequence envelope before refining at higher resolutions.
+2.  **Deterministic Symmetry Hardening**: Enforced symmetry deterministically during the expensive final $n=768$ resolution and the last 12% of the total time budget. This halves the effective search dimensionality when computation is most constrained.
+3.  **Atomic Peak-to-Gap Mass Migration**: Refined the "water-filling" move to surgically transfer mass from indices contributing most to convolution peaks to those contributing least, maintaining the sequence sum exactly and improving convergence stability.
+4.  **Symmetry-Aware Seeding and Evaluation**: Adjusted initial seeding to include the new $n=128$ resolution and ensured the greedy hill-climbing search remains consistent across resolution scales.

+<NAME>
+surgical_symmetry_optimization
+</NAME>
+
+<DESCRIPTION>
+Optimized the search strategy by:
+1.  **Introducing a Four-Stage Multi-Resolution Schedule**: Added $n=128$ as a fast-starting resolution and adjusted time shares (5%, 15%, 40%, 100%) to allow more thorough global shape discovery before high-resolution refinement.
+2.  **Enhancing Gradient Precision**: Increased the softmax $\beta$ range (up to 700) and step-size multiplier (from 20 to 30) for more surgical peak reduction.
+3.  **Refining Atomic Peak-to-Gap Migration**: Improved the mass transfer mechanism to be more stable and better integrated with symmetry.
+4.  **Implementing Final-Phase Symmetry Hardening**: Enforced deterministic symmetry during the final 15% of the search budget and resolution scaling, effectively halving the search space dimensionality when precision is most critical.
+5.  **Boosting Seeding Phase**: Expanded the initial seeding pool and included resolution 128 for faster initialization.

+<NAME>
+Multi_resolution_peak_reduction
+</NAME>
+
+<DESCRIPTION>
+This edit implements a structured multi-resolution search (128, 256, 512, 768) and a refined mutation strategy based on the most successful prior version (Gen 1). Key improvements:
+1.  **Multi-resolution Scaling**: Progressively increases the sequence length, using linear interpolation to preserve the global shape while allowing for finer local optimizations.
+2.  **Diverse Seeding**: Expands the initial search space with varied shapes (U-shape, bumps, sine waves) and early symmetry enforcement.
+3.  **Targeted Peak Reduction**: Implements a mutation move that identifies the specific sequence index most responsible for the highest convolution peak and reduces it.
+4.  **Cooling Schedule**: Applies a decaying noise factor (sigma) to transition from global exploration to local refinement as the time budget is consumed.
+5.  **Symmetry and Smoothing**: Periodically enforces symmetry and applies low-pass filtering to maintain stable, low-peak convolution profiles.

+<NAME>
+log_stable_mirror_descent
+</NAME>
+
+<DESCRIPTION>
+1.  **Implements Log-Stable Mirror Descent**: Replaces the heuristic gradient reduction with a theoretically grounded Mirror Descent update using the log-gradient of the objective function. This provides smoother and more stable convergence toward the optimal shape.
+2.  **Ultra-Sharpened Beta**: Increases the softmax parameter $\beta$ to 600 during the final resolution to surgically target the absolute convolution maxima.
+3.  **Atomic Mass Migration**: Refines the mass migration move to specifically shift mass from peak-contributing indices to low-contribution indices using an atomic operation.
+4.  **Optimal Time Allocation**: Reallocates the time budget to prioritize the final $n=768$ resolution and moves the symmetry "hardening" threshold to 0.70 for better global envelope stability.

+<NAME>
+Refined_Gradient_and_Atomic_Mass_Migration
+</NAME>
+
+<DESCRIPTION>
+Optimizes the sequence search by implementing three key improvements:
+1.  **Ultra-Sharp Softmax Gradient**: Increases the $\beta$ parameter from 40 up to 400 as the search progresses, using log-sum-exp-style normalization to isolate the indices most responsible for convolution peaks with surgical precision.
+2.  **Atomic Mass Migration**: Replaces independent additive/multiplicative moves with a direct transfer of "mass" from indices that contribute heavily to convolution peaks (high relative gradient) to those that are more "efficient" (low relative gradient), maintaining the sequence sum and improving convergence stability.
+3.  **Prior-Informed Seeding**: Adds a symmetric power-law initialization ($k^{-0.5} + (n-k)^{-0.5}$), which is a known theoretical structure for minimizing the AC inequality.
+4.  **Symmetry Hardening**: Increases the pressure towards symmetric solutions in the final stages of the high-resolution phase ($n=768$).

+<NAME>
+Adaptive_Symmetry_Resolution_Scaling
+</NAME>
+
+<DESCRIPTION>
+This edit introduces several refinements to the search process to break the 1.62 barrier:
+1.  **Resolution-Aware Annealing**: Resets the search intensity (`sigma`) at each resolution step using `res_progress`. This allows the algorithm to re-explore local variations when upscaling to $n=256, 512, 768$, rather than being stuck with the very small step sizes inherited from the previous resolution's completion.
+2.  **Stable Mirror Descent Scaling**: Scales the Mirror Descent update by the sequence length `n`. This ensures the effective step size is invariant to the resolution, as the sensitivity `gap` naturally scales with $1/n$.
+3.  **Expanded Power-Law Seeding**: Broadens the range of power-law exponents ($p$) to include values closer to the theoretical optimum.
+4.  **Refined Gradient Step**: Adjusts the Mirror Descent multiplier to maintain a healthy balance between exploration and refinement.

+<NAME>
+ultra_sharp_gradient_and_symmetry_hardening
+</NAME>
+
+<DESCRIPTION>
+Optimizes the search process by:
+1.  **Refining the Multi-Resolution Schedule**: Reallocating more time to the highest resolution ($n=768$) to allow for finer convergence of the convolution peaks.
+2.  **Implementing Ultra-Sharp Softmax Sensitivity**: Increasing the gradient-proxy $\beta$ from 200 up to 600 in the final stages. This identifies indices contributing to convolution maxima with near-surgical precision, using log-stable calculations to prevent overflow.
+3.  **Atomic Mass-Redistribution**: Refining the "Relative-Gradient Move" into a more robust sensitivity-balancing operation. This move identifies indices with high sensitivity to convolution peaks and redistributes their "mass" to low-sensitivity indices, maintaining the sequence sum more effectively.
+4.  **Deterministic Symmetry Hardening**: Transitioning from probabilistic to deterministic symmetry enforcement in the final 15% of the budget to halve the search dimensionality during the most expensive phase.
+5.  **Direct Power-Law Seeding**: Adding a specific $1/\sqrt{n}$ power-law seed, which is theoretically near-optimal for this class of autocorrelation problems.

+<NAME>
+multi_peak_gradient_and_compensation
+</NAME>
+
+<DESCRIPTION>
+This update improves the search strategy by:
+1.  **Refining Initialization**: Adding a U-shaped seed and broadening parameters for existing modes to cover a more diverse initial search space.
+2.  **Adaptive Resolution Scheduling**: Allocating more time to higher resolutions (especially n=768), where the objective is most sensitive and requires fine-tuning.
+3.  **Multi-Peak Gradient Move**: Replacing the single-peak gradient with a softmax-weighted gradient that considers all convolution peaks within a small percentage of the maximum. This prevents the search from oscillating between competing peaks and handles "flat-topped" convolution profiles more effectively.
+4.  **Compensation Mutation**: Adding a targeted move that identifies indices contributing the least to the convolution peaks and increases their values. This directly increases the total sum (the denominator of the objective) while having minimal impact on the maximum convolution value (the numerator).
+5.  **Robust Step Scaling**: Implementing a more stable gradient step size based on the ratio of the sequence norm to the gradient norm.

+Surgical_Entropic_Mirror_Descent
+</NAME>
+
+<DESCRIPTION>
+The optimization of the AC inequality objective $2n \max(a * a) / (\sum a)^2$ is refined by replacing heuristic multiplicative moves with a formal entropic Mirror Descent update.
+
+Key improvements:
+1.  **Entropic Mirror Descent**: Replaces the "Precision Softmax" move with an update of the form $A_{new} = A \cdot \exp(-\eta \nabla_{log})$, where the gradient is derived from the softmax-weighted peak of the convolution. This step naturally respects the non-negativity constraint and targets the indices responsible for the convolution peak with mathematical precision.
+2.  **Coupled Peak-to-Gap Migration**: A combined move that identifies indices contributing to convolution maxima (sources) and "valleys" (sinks), redistributing mass directly to flatten the convolution envelope without altering the global sum.
+3.  **Ultra-Sharp Softmax Schedule**: Increases the maximum softmax $\beta$ from 400 to 800 during the final resolution stage ($n=768$). This allows for "surgical" suppression of specific indices causing the $L_\infty$ bottleneck.
+4.  **Refined Resolution and Time Sharing**: Skews the search time more heavily towards the final resolution (65% of budget for $n=768$) to allow for more gradient-based refinement steps once the global power-law shape is established.
+5.  **Strict Symmetry Enforcement**: Given the problem's theoretical optima are symmetric, deterministic symmetry is forced more aggressively as progress reaches the final 25% of the time budget.

+log_gradient_mass_migration
+</NAME>
+
+<DESCRIPTION>
+This update implements a more principled optimization approach based on the recommendations:
+1.  **Log-Gradient Exponential Update**: Replaces heuristic multiplicative moves with a formal Mirror Descent step using the gradient of the log-objective. This naturally respects non-negativity and is more stable.
+2.  **Atomic Peak-to-Valley Mass Migration**: Adds a combined move that identifies indices contributing most to convolution maxima (hot) and minima (cold) simultaneously, transferring mass between them to flatten the $L_\infty$ norm efficiently.
+3.  **Ultra-Sharp Softmax Beta**: Increases the softmax temperature parameter $\beta$ (up to 600) to allow for surgical suppression of specific convolution peaks as the search approaches the deadline.
+4.  **Skewed Multi-Resolution Timing**: Adjusts the search schedule to spend significantly more time refining at the highest resolution ($n=768$), where the most gains are found.
+5.  **Strict Symmetry in Final Stage**: Deterministically enforces sequence symmetry in the final resolution or the last 15% of the budget to halve the search dimensionality.

+<NAME>
+Unified_Mirror_Descent_and_Symmetry_Optimization
+</NAME>
+
+<DESCRIPTION>
+The following improvements are proposed to push the performance beyond the 1.60 plateau:
+1.  **Unified Multiplicative Mirror Descent Step**: Replaced the heuristic independent peak reduction and valley boost moves with a formal multiplicative update. This move uses the gradient of the max-convolution objective to identify indices that contribute disproportionately to the peaks relative to the global mean, adjusting them using an exponential update that preserves non-negativity and maintains the sequence's power-law structure.
+2.  **Ultra-Sharp Peak Targeting**: Increased the maximum softmax $\beta$ to 500 in the final search stages. This allows the gradient computation to focus exclusively on the specific convolution indices responsible for the $L_\infty$ norm bottleneck, enabling surgical flattened-peak refinement.
+3.  **Deterministic Symmetry Reinforcement**: Given that theoretical optima for the AC inequality are symmetric, the search now increasingly enforces symmetry as the budget progresses. This effectively reduces the search dimensionality and stabilizes convergence at higher resolutions ($n=768$).
+4.  **Optimized Multi-Resolution Scheduling**: Adjusted the time-share allocation to provide more resources for the final $n=768$ resolution, ensuring that the global shape found at lower resolutions is fully refined at the maximum allowed complexity.
+5.  **Symmetry-Aware Mutations**: Updated block and gradient moves to preserve existing symmetry, preventing the search from wasting budget rediscovering symmetric shapes after found.

+mirror_descent_and_ultra_sharp_refinement
+</NAME>
+
+<DESCRIPTION>
+Optimizes the search for the AC inequality by implementing three major refinements:
+1.  **Ultra-Sharp Entropic Mirror Descent**: Increases the softmax sharpness ($\beta$) from 500 up to 1000 during the final resolution stage. This enables "nanosurgery" on the sequence to suppress specific indices responsible for convolution peaks without disturbing the global envelope.
+2.  **Improved Mass Migration**: Refines the "Peak-to-Gap" migration by using `mode='valid'` for gradient calculations, which is both more efficient and precise for identifying "valleys" in the convolution.
+3.  **Late-Stage Deterministic Symmetry**: Enforces 100% symmetry during the final 35% of the $n=768$ search phase. This effectively halves the search dimensionality at the most computationally expensive stage, allowing the algorithm to focus exclusively on refining the delicate symmetric power-law shapes that characterize optimal solutions.
+4.  **Tuned Resolution Scheduling**: Reallocates more time (65% vs 60%) to the final $n=768$ resolution where the most critical fine-tuning occurs.

+<NAME>
+peak_reduction_and_structured_search
+</NAME>
+
+<DESCRIPTION>
+Optimizing the search for a nonnegative step-function coefficient sequence by implementing three major improvements:
+1.  **Diverse Seeding**: Added a Beta-distribution shape (symmetric bump) to the initial seed pool to provide better starting points for the optimization.
+2.  **Structured Multi-Resolution Schedule**: Replaced the stochastic upsampling with a deterministic resolution schedule ([384, 512, 768]). This ensures the search spends dedicated time refining at the highest resolutions where the objective is most sensitive.
+3.  **Targeted Peak-Reduction and Compensation Mutations**:
+    -   Implemented a "Peak Reduction" move that identifies the indices contributing most to the maximum convolution values and selectively reduces them.
+    -   Implemented a "Compensation" move that increases values at indices with minimal contribution to peaks, raising the total sum without increasing the maximum convolution.
+    -   Added an FFT-based low-pass mutation to dampen high-frequency noise that causes convolution spikes.
+4.  **Computational Efficiency**: Used a faster, scale-aware evaluation formula within the search loop to increase the number of iterations possible within the budget.

+mirror_descent_and_targeted_migration
+</NAME>
+
+<DESCRIPTION>
+This update introduces a more principled approach to the sequence optimization by:
+1.  **Implementing Mirror Descent**: Replacing heuristic additive/multiplicative moves with a multiplicative update based on the gradient of the log-objective. This naturally respects the non-negativity constraint and provides more stable convergence towards the flattened convolution peaks.
+2.  **Sharper Softmax ($\beta$ up to 600)**: Increasing the softmax sharpness as the search progresses and resolutions increase, allowing for "nanosurgery" on the specific indices that contribute to the convolution's maximum.
+3.  **Edge-Tapered Seeding**: Adding a gentle window function ($\sin(\pi x)^{0.04}$) to initial power-law seeds to prevent artificial convolution spikes at the sequence boundaries.
+4.  **Optimized Mass Migration**: Refining the "Peak-to-Gap" move to identify indices contributing most to the convolution maxima and minima simultaneously, redistributing mass within the same move to maintain the sequence sum and directly flatten the $L_\infty$ norm.
+5.  **Strict Symmetry Enforcement**: Transitioning to deterministic symmetry in the final stages (last 10% of the budget), doubling the search efficiency during the high-resolution ($n=768$) refinement phase.

+<NAME>
+surgical_mass_migration_and_symmetry
+</NAME>
+
+<DESCRIPTION>
+Optimizes the sequence search by:
+1. Refining the surgical move into a principled mass-migration update based on the objective's log-gradient (natural gradient step), ensuring the total sum remains balanced while reducing peak-contributing elements.
+2. Increasing the softmax beta to 100-1000 to isolate convolution spikes with nanosurgical precision.
+3. Implementing a patience-based 'sigma boost' to escape local minima when the objective plateaus.
+4. Enforcing strict symmetry at high resolutions (n=512, 768) to halve the search space dimensionality and focus on the theoretical symmetric optima.
+5. Tuning multi-resolution time shares to provide 65% of the budget for the final 768-resolution refinement.

+<NAME>
+surgical_flattening_and_refined_migration
+</NAME>
+
+<DESCRIPTION>
+Optimized the search strategy by focusing on surgical peak-to-valley mass migration and a more principled mirror descent step.
+1.  **Focused Resolutions**: Simplified the multi-resolution search to [512, 768] to maximize the number of iterations at high precision.
+2.  **Principled Mirror Descent**: Rederived the mirror descent gradient to ensure unit consistency and stable step sizes. Used a normalized dimensionless relative gradient $( (grad\_norm \cdot sum\_a / max\_c) - 1.0 )$.
+3.  **Surgical Mass Migration**: Instead of using weight masks for both peaks and valleys, this move now calculates the convolution gradient once with a very high beta (up to 1000) and directly moves mass from the highest gradient indices (responsible for peaks) to the lowest (responsible for valleys).
+4.  **Enhanced Nanosurgery**: Increased the softmax $\beta$ significantly (up to 1200) as the search progresses, allowing for extremely precise adjustments to sequence elements causing convolution spikes.
+5.  **Aggressive Symmetry**: Enforced sequence symmetry more consistently in the final resolution to halve the effective search dimensionality.

+<NAME>
+surgical_mass_migration_and_half_length_opt
+</NAME>
+
+<DESCRIPTION>
+This edit implements three strategic improvements:
+1. **Unified Peak-to-Valley Mass Migration**: Replaces independent shaving/boosting with a move that explicitly identifies indices contributing most to convolution peaks (via a sharpened softmax gradient) and migrates their mass to "valley" indices. This preserves the sequence sum and directly flattens the convolution envelope.
+2. **Deterministic Half-Length Optimization**: When the sequence is symmetric (or in the final high-resolution phase), mutations are focused on the first half of the sequence and then mirrored. This effectively halves the search dimensionality, allowing for more iterations and better refinement at $n=768$.
+3. **Nanosurgery Beta Scaling**: Increases the softmax sharpness ($\beta$) up to 1000 during the final phase to isolate exactly which elements are responsible for convolution spikes, enabling precise multiplicative reductions that don't destroy the overall power-law shape.
+4. **Patience-Aware Resolution Scaling**: Adjusts the resolution jump logic and step-size ($\sigma$) based on improvement plateauing.

+Surgical_Mass_Migration_and_High_Beta_Refinement
+</NAME>
+
+<DESCRIPTION>
+Optimizes the search by implementing a unified Peak-to-Valley mass migration move and increasing softmax sensitivity to 800 for "nanosurgery" on convolution spikes.
+
+1. **Peak-to-Valley Migration**: Identifies indices contributing most to convolution peaks and redistributes their mass to indices contributing to convolution valleys. This preserves the sequence sum and directly flattens the convolution.
+2. **Nanosurgery Beta**: Increases the softmax sharpness parameter $\beta$ significantly (up to 800) as the search progresses, allowing for isolation of the exact sequence elements responsible for the current convolution maximum.
+3. **Forced Symmetry Phase**: From 50% progress onwards, the search space is effectively halved by forcing strict symmetry at every iteration, accelerating refinement in the final stages.
+4. **Time-Share Optimization**: Rebalances the time allocated to higher resolutions to ensure the $n=768$ stage has sufficient budget for fine-grained adjustment.

+unified_migration_and_nanosurgery
+</NAME>
+
+<DESCRIPTION>
+Optimizes the search by implementing a unified Peak-to-Valley Mass Migration move and an ultra-sharp surgical gradient descent.
+1. **Unified Peak-to-Valley Mass Migration**: Instead of independent boost and reduction moves, mass is directly transferred from indices contributing most to the convolution peak to those contributing least, preserving the sequence sum and flattening the $L_\infty$ norm more efficiently.
+2. **Nanosurgery Softmax $\beta$**: Increases the softmax sharpness ($\beta$) up to 1000 during final refinement to isolate exact elements responsible for convolution spikes.
+3. **Deterministic Half-Length Optimization**: During the final 20% of the budget, mutations are forced to be symmetric by operating only on the first half of the sequence, effectively halving the search dimensionality.
+4. **Spectral Low-Pass Cleanup**: Periodically applies a low-pass filter to prevent high-frequency "jitter" from building up during point-wise mutations.

+Symmetric_Nanosurgery_and_Mass_Migration
+</NAME>
+
+<DESCRIPTION>
+Optimizes the step-function sequence by implementing four key enhancements:
+1.  **Refined Seeding**: Incorporates windowed power-law distributions (known priors for AC-inequality optima) and Tukey-like tapering to provide better starting points.
+2.  **Symmetric-Aware Mutations**: Most perturbations (block, scattered, gradient) are applied symmetrically if the sequence is currently symmetric, effectively halving the search space and preserving the optimal symmetric structure.
+3.  **Unified Peak-to-Valley Mass Migration**: Instead of independent scaling, mass is surgically moved from indices contributing most to convolution peaks to those contributing least, preserving the sequence sum while flattening the convolution $L_\infty$ norm.
+4.  **High-Beta Gradient Descent (Nanosurgery)**: Uses a stable, high-exponent softmax ($\beta$ up to 800) to isolate exact spike contributors, coupled with entropic mirror descent to refine the sequence envelope smoothly.
+5.  **Time-Weighted Scheduling**: Skews computational budget toward the final $n=768$ resolution for high-precision fine-tuning.

+<NAME>
+Symmetry_Reduced_Surgical_Search
+</NAME>
+
+<DESCRIPTION>
+Optimizing the step-function coefficient sequence for the AC inequality by:
+1.  **Dimensionality Reduction**: Explicitly halving the mutation space for the final resolution ($n=768$) and late search stages by mutating only the first half of the sequence and mirroring, which doubles iteration throughput and preserves symmetry by construction.
+2.  **Surgical Log-Gradient Refinement**: Implementing the true gradient of the log-objective ($\nabla \log O = 2(\nabla P/P - 1/S)$) with a smoothed kernel to prevent high-frequency jitter.
+3.  **Enhanced Mass Migration**: Specifically targeting peak-contributing indices using high-beta softmax ($\beta$ up to 800) and redistributing mass to valley-contributing indices to flatten the convolution product $L_\infty$ norm more effectively.
+4.  **Skewed Time Allocation**: Adjusting time shares to focus even more budget on the high-resolution refinement stage where the most significant gains occur.

+<NAME>
+nanosurgery_smoothing_and_symmetry
+</NAME>
+
+<DESCRIPTION>
+This edit implements several refinements to the search process to break the 1.60 plateau:
+1.  **Smoothed Gradient Moves**: Applied a 3-tap Gaussian-like kernel `[0.15, 0.7, 0.15]` to the update masks in "Nanosurgery," "Migration," and "Peak Pressure" moves. This prevents the introduction of high-frequency noise that often creates secondary convolution spikes.
+2.  **Ultra-Sharp Nanosurgery**: Increased the maximum softmax $\beta$ to 1000 and shifted the exponent to `progress**1.5` to ensure surgical precision in the final refinement stages.
+3.  **Aggressive High-Resolution Timing**: Adjusted `time_shares` to `[0.04, 0.12, 0.32, 1.0]` to devote more budget to the critical $n=768$ resolution.
+4.  **Refined Mass Migration**: Improved the "Unified Peak-to-Valley" move to use smoothed subtraction and addition masks, better preserving the global sequence envelope while flattening the convolution $L_\infty$ norm.
+5.  **Deterministic Symmetry**: Enforced symmetry earlier ($progress > 0.4$) and more consistently to reduce the search dimensionality.

+<NAME>
+surgical_gradient_refinement
+</NAME>
+
+<DESCRIPTION>
+Optimizes the step-function coefficient sequence by refining the multi-resolution search strategy and mutation operators.
+
+Key improvements:
+1.  **Surgical Gradient Moves**: Increases the softmax beta to 1500 and applies Gaussian smoothing to the gradient mask. This allows for more precise "nanosurgery" on the sequence elements contributing to convolution spikes while preventing high-frequency jitter that creates new peaks.
+2.  **Strategic Time Allocation**: Reallocates the time budget to favor the final resolution (n=768), providing more iterations for the most expensive and critical refinement stage.
+3.  **Refined Mass Migration**: Implements a more focused peak-to-valley mass redistribution that uses a surgical gradient to identify and shave only the most problematic elements.
+4.  **Diverse Initial Seeding**: Adds a triangular/tent-shaped seed to the initialization pool, broadening the search starting points.
+5.  **Aggressive Symmetry Enforcement**: Increases the deterministic symmetry enforcement threshold to 70% of the search timeline, as the theoretical optima for this AC inequality are likely symmetric.

+nanosurgery_and_symmetry_refinement
+</NAME>
+
+<DESCRIPTION>
+This update implements several strategic improvements to the search process for the optimal autocorrelation sequence:
+1. **Deterministic Symmetry Focus**: In the final high-resolution phase ($n=768$), the search dimensionality is effectively halved by forcing sequence symmetry, where the most competitive solutions are known to reside.
+2. **Unified Nanosurgery Gradient Migration**: Replaces independent peak-shaving moves with a unified gradient step using an ultra-high softmax $\beta$ (up to 1000). This surgically identifies elements contributing most to the convolution peaks and redistributes their mass using a smoothed log-objective gradient update.
+3. **Adaptive Gaussian Smoothing**: Replaces the fixed kernel with a resolution-adaptive Gaussian kernel to smooth the gradient update, preventing high-frequency jitter while surgically flattening the convolution envelope.
+4. **Scattered Perturbation**: Adds a symmetry-aware scattered mutation move to provide better exploration of the sequence space than block perturbations alone.

+<NAME>
+surgical_gradient_and_mass_migration
+</NAME>
+
+<DESCRIPTION>
+Optimized the sequence refinement process by implementing a "Surgical Efficiency Gradient Step" and a "Peak-to-Valley Mass Migration".
+
+1.  **Surgical Efficiency Gradient Step**: Increased the softmax $\beta$ to 800 (using a quadratic progress-based schedule) to isolate specific peaks during the final resolutions. The gradient is now smoothed using a 3-tap kernel to prevent high-frequency jitter, and the update is scaled by a "relative efficiency" metric (contribution to peak vs. contribution to mass) to ensure mass is only removed from the most problematic indices.
+2.  **Peak-to-Valley Mass Migration**: Replaced the random mass transfer with a deterministic move. It identifies indices with the highest contribution to convolution peaks and moves a portion of their mass to indices with the lowest contribution, directly flattening the $L_\infty$ norm of the convolution while preserving the total sequence sum.
+3.  **Refined Sigma Decay**: Adjusted the noise schedule to allow for slightly more exploration in the early stages and smoother convergence in the final high-resolution phase.

+<NAME>high_beta_gaussian_nanosurgery</NAME>
+
+<DESCRIPTION>
+This optimization introduces "High-Beta Gaussian Nanosurgery" to move past the 1.60 threshold.
+
+1.  **Escalated Softmax Beta**: The softmax $\beta$ is increased to a maximum of 800 during the final resolution phase ($n=768$), allowing the optimizer to isolate and penalize only the specific indices responsible for the convolution peaks.
+2.  **Gaussian-Smoothed Mutation Masks**: Multiplicative gradient and peak pressure moves now utilize local smoothing (convolution with a `[0.1, 0.8, 0.1]` kernel). This prevents high-frequency "jitter" in the sequence envelope, which often induces secondary spikes in the convolution that stall progress.
+3.  **Strict Dimensionality Reduction for Symmetry**: When the sequence is detected as symmetric, the algorithm explicitly perturbs only the first half of the sequence and mirrors it. This effectively halves the search space dimensionality, doubling search efficiency in the final expensive resolution phase.
+4.  **Refined Migration Logic**: The mass-migration step is updated to use a more stable exponential scaling based on the relative gradient, ensuring mass is transferred from peak-heavy indices to peak-light ones without destabilizing the sequence sum.

+surgical_nanosurgery_and_symmetry_scaling
+</NAME>
+
+<DESCRIPTION>
+Optimizes the nonnegative coefficient search by refining several key components:
+1.  **Beta Escalation**: Increases the softmax beta from 800 to 1280 during the search to allow for "nanosurgery" on specific convolution peaks, especially at the final resolution.
+2.  **Unitless Gradient Updates**: Refines the surgical gradient step to use a unitless relative efficiency metric, ensuring more stable multiplicative updates.
+3.  **Targeted Mass Migration**: Enhances the peak-to-valley mass migration move by making it progress-dependent and deterministic, targeting high-gradient (peak-inducing) and low-gradient (valley) indices.
+4.  **Symmetry and Resolution Ladder**: Skews the time budget more heavily toward the final resolution (768) and adds a tapered power-law candidate to the seed pool.
+5.  **Gaussian Smoothing**: Applies a refined 5-point Gaussian kernel to the surgical gradient to prevent high-frequency artifacts that create secondary convolution peaks.

+<NAME>
+greedy_peak_targeting_and_multi_res
+</NAME>
+
+<DESCRIPTION>
+This update improves the search by integrating greedy peak reduction and compensation strategies, which were highly effective in earlier generations. It shifts the optimization from a purely gradient-focused approach to a hybrid stochastic search.
+
+Key improvements:
+1.  **Resolution Schedule**: Reverts to a 4-step resolution scale [128, 256, 512, 768] to allow more progressive refinement.
+2.  **Greedy Peak Reduction**: Specifically targets and reduces the indices that contribute most to the current convolution peak, bypassing potential issues with gradient smoothness.
+3.  **Compensation Move**: Identifies indices that contribute least to convolution peaks and boosts their values to increase the total sum (S) without significantly raising the peak (P), directly improving the $P/S^2$ ratio.
+4.  **Diverse Seeding**: Enhances the initial pool with a mix of Beta-shaped, sinusoidal, and constant sequences to explore more diverse basins of attraction.
+5.  **Refined Normalization**: Ensures numerical stability by clipping values during the normalization step.

+<NAME>
+surgical_log_gradient_and_mass_migration
+</NAME>
+
+<DESCRIPTION>
+Optimized the sequence refinement process by implementing a full-sequence Multiplicative Mirror Descent update based on the gradient of the log-objective. This "nanosurgery" approach uses an escalated softmax beta (up to 1500) to precisely isolate convolution peaks and applies a Gaussian-like smoothing kernel to the gradient to prevent high-frequency noise and jaggedness in the sequence envelope. Additionally, the mass migration move was refined to be more deterministic, transferring mass from indices with the highest convolution contribution directly to those with the lowest. Symmetry enforcement is now strictly applied during the final 20% of the budget to halve the search dimensionality at the highest resolution ($n=768$).

+<NAME>
+surgical_mass_migration
+</NAME>
+
+<DESCRIPTION>
+This edit introduces two primary improvements to the optimization search:
+1.  **Smoothed Unified Surgical Gradient Step**: Enhances the existing gradient-based update by increasing the softmax beta (from 900 to 1200) for "nanosurgery" on the primary convolution peak. It also incorporates Gaussian smoothing on the gradient mask (via `np.roll`) to prevent the creation of new high-frequency spikes.
+2.  **Mass-Preserving Peak-to-Valley Migration**: Replaced the spectral smoothing mutation with a deterministic mass migration move. This move identifies indices that contribute most to convolution peaks and redistributes a fraction of their mass to indices identified as "valleys" (low gradient). This directly flattens the autocorrelation profile while maintaining the sequence sum.
+3.  **Adaptive Schedule Refinement**: Slightly increased the initial `sigma` and adjusted the decay exponent (1.25 to 1.1) to allow for more sustained exploration in the final $n=768$ resolution, while also giving the high-resolution phase a larger share of the total time budget.

+<NAME>
+nanosurgery_and_mass_redistribution
+</NAME>
+
+<DESCRIPTION>
+To break the 1.60 barrier, I am implementing several targeted refinements:
+1. **Surgical Nanosurgery Beta Scaling**: Increased the softmax beta from 750 to 1100 in the final search stages to isolate and target convolution peaks with extreme precision.
+2. **Gaussian Delta Smoothing**: Introduced a smoothing kernel to mutation deltas and gradients. This prevents the introduction of high-frequency jaggedness ("spikes") that often create secondary convolution peaks and stall convergence.
+3. **Refined Mass-Preserving Migration**: Redesigned the peak-to-valley migration to be more aggressive and precise, moving mass from the most problematic indices (highest gradient) directly to the "valleys" (lowest gradient) to maintain a flatter convolution profile without shifting the global scale.
+4. **Adaptive Dimensionality**: Enhanced the symmetry preservation during mutations, ensuring that improvements in one half of the sequence are immediately mirrored, effectively halving the search space and accelerating convergence at high resolutions ($n=768$).
+5. **Dynamic Sigma Decay**: Adjusted the mutation scale (sigma) to decay more sharply at high progress, allowing for more robust exploration in the early phase and finer "nanosurgery" in the final 10% of the budget.

+<NAME>
+precision_nanosurgery_and_mass_migration
+</NAME>
+
+<DESCRIPTION>
+To break the 1.60 barrier, I am proposing several synergistic improvements to the search algorithm:
+1.  **Escalated Softmax Beta (Nanosurgery)**: Increase the softmax beta parameter up to 1000 during the final optimization phase. This isolates the specific indices responsible for the absolute convolution peak with extreme precision, allowing for "surgical" refinement.
+2.  **Gaussian Gradient Smoothing**: Apply a narrow Gaussian-like kernel ([0.15, 0.7, 0.15]) to the sensitivity gradient before applying updates. This prevents the "nanosurgery" from introducing high-frequency jaggedness, which often creates secondary convolution peaks that stall convergence.
+3.  **Mass-Preserving Peak-to-Valley Migration**: Introduce a deterministic mutation that subtracts mass from indices contributing most to the convolution peak and redistributes it to "valleys." This flattens the $L_\infty$ profile while maintaining the sequence sum, which is more stable than global normalization.
+4.  **Sharpened Power-Law Seeds**: Narrow the power-law exponent search to the $0.48-0.52$ range, which is theoretically closer to the optimal basin for the AC inequality.
+5.  **Deterministic Final Symmetry**: Enforce symmetry strictly in the final 8% of the time budget to ensure the search space is effectively halved for fine-tuning at the highest resolution.
+</DESCRIPTION>

+<NAME>
+advanced_peak_optimization
+</NAME>
+
+<DESCRIPTION>
+This edit enhances the search algorithm with four targeted improvements:
+1.  **Surgical Peak Reduction**: Re-introduces the highly effective Gen 1 mutation that identifies the specific pair of indices contributing most to the maximum convolution peak and reduces them directly.
+2.  **Softmax Multi-Peak Gradient**: Replaces the single-peak gradient move with a more stable softmax-based gradient that considers all peaks near the maximum simultaneously.
+3.  **Valley-Filling Compensation**: Adds a move that increases values at indices that contribute the least to convolution peaks, raising the total sum (S) without impacting the peak (P).
+4.  **U-Shaped Seeding**: Adds a U-shaped distribution to the initial seeding pool, which is a known structural candidate for minimizing auto-correlation ratios.
+5.  **Adaptive Resolution Schedule**: Reallocates more runtime budget to higher resolutions (512 and 768), where the objective is most sensitive and requires finer tuning.

+<NAME>
+surgical_gradient_search_optimization
+</NAME>
+
+<DESCRIPTION>
+Optimizes the search algorithm by implementing several key enhancements to cross the 1.60 threshold:
+1.  **Convolutional Efficiency Boost**: Reduces the computational cost per iteration by 50% by caching the convolution and peak values of the current best sequence. Gradient-based mutations now use the sensitivity profile of the `best_seq` to propose candidates, and only a single convolution is performed per iteration (post-mutation) to evaluate the new sequence.
+2.  **Sharpened Nanosurgery with Gaussian Smoothing**: Increases the softmax $\beta$ to 1200 as search progresses to isolate convolution peaks with extreme precision. Multiplicative reductions are now applied through a Gaussian-smoothed mask to prevent high-frequency noise and secondary peak generation.
+3.  **Refined Mass Migration**: Directly targets indices with the highest contribution to convolution valleys while subtracting mass from peak contributors, ensuring the sequence profile flattens efficiently.
+4.  **Enhanced Seeding and Timing**: Shifts the initial seeding to higher resolutions and optimizes the time-shares to allocate over 65% of the budget to the $N=768$ refinement phase.
+5.  **Robust Symmetry Phase**: Transitions to strict symmetry enforcement and symmetry-aware mutations during the second half of the search budget.

+<NAME>
+surgical_symmetry_optimization
+</NAME>
+
+<DESCRIPTION>
+Optimizes the sequence search by implementing the following improvements:
+1. **Strict Half-Length Symmetry Optimization**: When `force_symmetry` is active (after 40% progress), mutations are concentrated on the first half of the sequence and mirrored. This reduces the search space dimensionality by half, significantly accelerating convergence.
+2. **Stable High-Beta Nanosurgery**: Increases the softmax beta to 1100 during later stages and utilizes a numerically stable `(c - max_c) / max_c` formula to isolate and reduce specific elements contributing to the convolution peaks.
+3. **Redistributive Mass Migration**: Replaces independent peak reduction with a migration move that subtracts mass from high-sensitivity (peak-contributing) indices and redistributes it to low-sensitivity (valley) indices, naturally preserving the sequence sum while flattening the profile.
+4. **Gaussian Mutation Smoothing**: Applies a smoothing kernel to multiplicative masks in the gradient-based moves, preventing high-frequency jaggedness and the formation of secondary peaks that often stall progress in high-resolution refinement.
+5. **Adjusted Resolution Timing**: Skews the time budget further towards the $N=512$ and $N=768$ phases to allow for finer surgical adjustments in the final convergence stages.

+nanosurgery_migration_optimizer
+</NAME>
+
+<DESCRIPTION>
+Optimizes the step-function sequence by implementing a mass-preserving "Migration Move" that deterministically flattens the convolution peak. The optimizer identifies indices responsible for convolution $L_\infty$ peaks using a numerically stable high-beta ($\beta=1000$) softmax-gradient proxy, smoothed with a Gaussian kernel to prevent high-frequency noise. Mass is surgically moved from peak-contributing indices to "valleys" (inefficient indices), maintaining the internal sequence sum $\sum a = n$ more naturally. The resolution ladder and mutation sigma are adjusted to prioritize high-resolution refinement and late-stage convergence.

+surgical_gradient_and_mass_migration
+</NAME>
+
+<DESCRIPTION>
+Optimized the search strategy by:
+1.  **Refining the Seeding Phase**: Adjusted power-law exponents to focus on theoretical candidate shapes (p ≈ 0.5) and used faster evaluation to explore more seeds within the same time budget.
+2.  **Enhancing Mirror Descent (Nanosurgery)**: Corrected the gradient calculation to use `mode='valid'` for efficiency and added Gaussian smoothing to `rel_grad` to prevent high-frequency noise and local "spikes" from stalling convergence.
+3.  **Implementing Surgical Mass Migration**: Replaced the "Peak Pressure" move with a principled mass-preserving migration that shifts mass from indices contributing most to convolution peaks to "valleys" (indices with lowest gradient sensitivity), directly flattening the $L_\infty$ profile without shifting the sequence sum.
+4.  **Strengthening Symmetry Reinforcement**: Simplified symmetry enforcement and prioritized it more heavily in high-resolution phases to focus the search budget on the optimal symmetric form.
+5.  **Optimizing Resolution Scaling**: Adjusted the resolution ladder and time shares to allocate more iterations (55% of the budget) to the final $N=768$ refinement phase.

+<NAME>
+surgical_beta_escalation_and_mass_migration
+</NAME>
+
+<DESCRIPTION>
+Optimizes the refinement process by implementing several surgical improvements:
+1.  **High-Beta Escalation**: Increases the softmax $\beta$ up to 1000 during the final resolution phase. This allows the optimizer to isolate and adjust the exact sequence elements responsible for convolution peaks with "nanosurgical" precision.
+2.  **Mass-Preserving Migration**: Introduces a move that deterministicly subtracts mass from indices contributing to convolution peaks and redistributes it to "valleys" (indices with the lowest gradient sensitivity), maintaining the internal sequence sum naturally.
+3.  **Resolution-Skewed Budget**: Reallocates the time budget to favor the highest resolution ($N=768$), where the most gains are made in flattening the $L_\infty$ profile.
+4.  **Gaussian Gradient Smoothing**: Applies a narrow smoothing kernel to gradient updates to prevent high-frequency jitter and "spikes" that often lead to secondary local convolution peaks.
+5.  **Targeted Peak Pressure**: Adds a deterministic move that identifies the exact pair contribution at the convolution's maximum index and performs a multiplicative reduction.

+<NAME>
+surgical_mirror_descent_and_mass_migration
+</NAME>
+
+<DESCRIPTION>
+Optimizes the search process by implementing a more robust "Nanosurgery" approach.
+1.  **Stable High-Beta Softmax**: Increases the softmax beta up to 1200.0 as the search progresses, allowing the gradient to target the convolution peaks with much higher precision.
+2.  **Surgical Mirror Descent**: Replaces the independent multiplicative moves with a Mirror Descent-inspired update using the gradient of the log-objective. This naturally maintains non-negativity and provides more stable convergence.
+3.  **Gaussian Gradient Smoothing**: Applies a small Gaussian kernel to the update vector to prevent the introduction of high-frequency noise and "spikes" which often create new convolution peaks.
+4.  **Enhanced Mass Migration**: Refines the mass migration move to deterministically move mass from high-gradient (peak-contributing) indices to low-gradient indices, maintaining the sequence sum more effectively.
+5.  **Strict Symmetry Enforcement**: Increases the frequency of symmetry enforcement in the final 15% of the time budget, as optimal solutions are known to be symmetric.
+6.  **Resolution Scaling**: Adjusts the time shares to allocate more time to the highest resolution (N=768).

+<NAME>
+surgical_mass_migration_refinement
+</NAME>
+
+<DESCRIPTION>
+Refines the mass-preserving migration optimizer and the symmetry enforcement logic to break the 1.61 performance ceiling.
+
+Key improvements:
+1.  **Escalated Nanosurgery**: Increases the softmax beta to 1500 in the final search phase, allowing the optimizer to isolate and flatten specific convolution peaks with much higher precision.
+2.  **Gaussian Gradient Smoothing**: Applies a smoothing kernel to the relative impact (gradient) vector. This prevents the "nanosurgery" from introducing high-frequency jaggedness or "spikes" that often create secondary convolution peaks and stall convergence.
+3.  **Corrected Log-Gradient Scaling**: Adjusts the mass migration step size and increases the boundary of the primary optimizer move to 75% of the mutation distribution.
+4.  **Deterministic Symmetry Phase**: Switches to a more aggressive symmetry enforcement strategy after 70% progress, as the optimal solution for this inequality is known to be symmetric.

+<NAME>
+surgical_nanosurgery_migration
+</NAME>
+
+<DESCRIPTION>
+Optimizes the step-function coefficient sequence using a high-precision multi-resolution search. Key improvements include:
+1.  **Strict Mirror Descent**: Refines the Mirror Descent gradient step by correctly calculating the relative contribution of each sequence element to the convolution peak, using a super-high beta softmax ($\beta$ up to 1500) to isolate the $L_\infty$ contribution.
+2.  **Surgical Mass Migration**: Implements a mass-preserving migration move that redistributes mass from peak-contributing indices to "valleys" (indices with minimum gradient sensitivity), directly flattening the convolution profile.
+3.  **Diverse Seeding**: Enhances initial search with a wider variety of structured candidates, including symmetric power-laws ($x^{-1/2}$) and step-function hills.
+4.  **Gaussian Gradient Smoothing**: Applies local smoothing to the mutation deltas to prevent the introduction of high-frequency noise that could stall convergence in high-resolution phases.
+5.  **Refined Resolution Ladder**: Skews the computational budget more aggressively towards the final $N=768$ refinement stage and utilizes a faster internal evaluation loop.

+<NAME>
+nanosurgery_migration_optimization
+</NAME>
+
+<DESCRIPTION>
+This edit implements four key refinements to the optimization process to break the 1.61 performance ceiling:
+1. **Surgical Mirror Descent**: Replaces simple multiplicative reductions with a principled Mirror Descent gradient step using the exact gradient of the log-objective function. It incorporates a super-high beta softmax (up to 1500) to isolate peak-contributing elements and applies Gaussian smoothing to the gradient to prevent high-frequency artifacts.
+2. **Mass-Preserving Peak-to-Valley Migration**: Implements a deterministic mass migration move that subtracts mass from peak-contributing indices and redistributes it to the most efficient "valleys," maintaining the sequence sum naturally.
+3. **Aggressive Symmetry Enforcement**: Transitions to deterministic symmetry preservation earlier in the high-resolution phases (512 and 768 scales), halving the effective search dimensionality.
+4. **Enhanced Numerical Stability**: Uses a robust softmax implementation `np.exp(np.clip(beta * (c - max_c) / max_c, -60, 0))` to prevent numerical overflow while maintaining the extreme precision required for late-stage refinement.

+<NAME>
+surgical_mirror_migration_refinement
+</NAME>
+
+<DESCRIPTION>
+The following refinements are proposed to the optimization process:
+1.  **Enhanced Mirror Descent Step**: Refines the surgical gradient-based move by increasing the softmax beta to 2000 in the final stage, allowing for more precise identification of peak-contributing indices. The update rule is adjusted to a more stable multiplicative Mirror Descent step using a correctly normalized relative gradient.
+2.  **Symmetric Mass-Migration**: Upgrades the peak-to-valley mass migration to be more surgical, redistributing mass from peak contributors to the indices with the lowest gradient sensitivity, preserving the sequence sum naturally.
+3.  **Annealed Sigma Schedule**: Adjusts the perturbation scale `sigma` to provide more exploration room early in each resolution phase while maintaining convergence at the end.
+4.  **Resolution-Aware Initialization & Smoothing**: Refines the initial power-law seeds and adds localized smoothing immediately after resolution upscaling to prevent artifacts from stalling the optimizer.
+5.  **Targeted Spectral Damping**: Focuses spectral mutations more strictly on high-frequency damping while adding controlled low-frequency noise to explore global shapes.

+nanosurgery_migration_optimizer
+</NAME>
+
+<DESCRIPTION>
+This optimization introduces several advanced refinement techniques to reach the 1.60-1.62 performance tier:
+1.  **Ultra-High Beta Nanosurgery**: Increases the softmax weight $\beta$ up to 1200 during the final resolution phase. This isolates the exact coefficients responsible for the $L_\infty$ convolution peak, allowing for surgical reductions without affecting the rest of the envelope.
+2.  **Symmetric Power-Law Seeding**: Re-introduces the theoretical optimal candidate shape (symmetric power law) into the initial seed pool to provide a better starting point for the optimizer.
+3.  **Gaussian-Smoothed Gradient Updates**: Applies a narrow Gaussian kernel to the calculated gradient before the Mirror Descent update. This prevents the "jitter" or high-frequency spikes that often emerge when targeting specific indices, which typically create new secondary convolution peaks.
+4.  **Coupled Mass Migration**: Replaces independent reductions and boosts with a migration move that subtracts mass from indices with the highest gradient sensitivity (peaks) and adds it to indices with the lowest sensitivity (valleys), keeping the total mass more stable.
+5.  **Strict Late-Stage Symmetrization**: Enforces sequence symmetry more aggressively in the final 25% of the time budget for the $n=768$ resolution, as the optimal solution is mathematically known to be symmetric.

+<NAME>
+surgical_mirror_descent_with_powerlaw_seeds
+</NAME>
+
+<DESCRIPTION>
+Optimized the search strategy by:
+1. Adding a Symmetric Power Law seeding mode, a known strong candidate for autocorrelation inequalities.
+2. Replacing the independent sensitivity moves with a unified Mirror Descent update derived from the log-gradient of the objective function, using a high-beta softmax to surgically isolate convolution peaks.
+3. Introducing a coupled Mass Migration move that redistributes mass from high-impact indices to low-impact indices, ensuring better numerical stability.
+4. Skewing the time-share budget significantly toward the final $n=768$ resolution for fine-tuning.
+5. Implementing a more aggressive deterministic symmetry enforcement in the later stages of the search to focus the optimization on the symmetric subspace.

+<NAME>
+Refined_Spectral_and_Peak_Moves
+</NAME>
+
+<DESCRIPTION>
+Optimized the search by refining the mutation strategies and initialization.
+1.  **Diverse Seeding**: Added a Gaussian-bump initialization and expanded the seeding phase to explore more starting points.
+2.  **Multi-Peak Targeted Reduction**: Replaced the single-peak reduction with a randomized top-K peak targeting approach. This identifies indices contributing most to any of the convolution peaks near the maximum, providing more robust peak dampening.
+3.  **Broad Usage-based Compensation**: Improved the compensation move to target indices that contribute to the fewest high-value convolution peaks, effectively boosting the denominator $(\sum a)^2$ without increasing the numerator.
+4.  **Spectral Mutation**: Enhanced the FFT-based smoothing into a spectral mutation that both applies a low-pass filter and randomly perturbs low-frequency Fourier components, allowing for more structured global shape changes.
+5.  **Refined Mutation Schedule**: Adjusted mutation probabilities and the resolution scaling schedule to spend more time on high-impact moves like peak reduction and spectral mutations.

+<NAME>
+surgical_peak_and_asymmetric_search
+</NAME>
+
+<DESCRIPTION>
+Optimized the search by prioritizing "Surgical Peak Reduction" and "Asymmetric Seeding".
+
+1.  **Asymmetry-Focused Seeding**: Since symmetry in the coefficient sequence guarantees a high central convolution peak ($\sum a_i^2$), breaking symmetry is crucial. I updated the seeding to include quadratic chirps and reduced the probability of symmetry enforcement.
+2.  **Top-K Surgical Peak Reduction**: Improved the peak reduction move to identify all convolution indices within 2% of the maximum and randomly target them. This prevents the search from oscillation between two similar peaks.
+3.  **Refined Denominator Boosting**: The "Valley-Filling" move now utilizes the gradient of the convolution peak (the contribution vector `gm`) to identify indices that increase the denominator $(\sum a)^2$ while having the least impact on the numerator $\max(a*a)$.
+4.  **Adaptive Gradient Step**: Adjusted the gradient-based mutation to use a progressively sharpening softmax (via increasing $\beta$) and improved the step-size scaling.
+5.  **Resolution Schedule**: Re-allocated time to favor the highest resolution (50% of the total budget) for finer local optimization.

+<NAME>
+sensitivity_guided_optimization
+</NAME>
+
+<DESCRIPTION>
+This update implements a more robust optimization strategy based on the "sensitivity" of the auto-convolution peaks to sequence perturbations.
+
+Key improvements:
+1.  **Multi-Peak Sensitivity Targeting**: Replaced the random-peak selection with a softmax-weighted sensitivity vector. This identifies the indices that most contribute to all high-convolution peaks simultaneously. The "reduction" move now targets the index with the highest multiplicative sensitivity, and the "compensation" move targets the index with the lowest.
+2.  **Symmetry Preservation**: If a sequence becomes symmetric (a common property of optimal solutions), the search now prioritizes moves that maintain that symmetry, accelerating convergence in the most promising regions of the search space.
+3.  **Refined Seeding and Normalization**: Diversified the initial sequence pool with Beta-like and multi-modal distributions while ensuring all seeds start with a higher probability of symmetry.
+4.  **Adaptive Step-Sizing**: Updated the noise parameter $\sigma$ to decrease more smoothly and maintain a small floor, ensuring the search doesn't stall during the final resolution phase.
+5.  **Robust Fast-Evaluation**: Maintains the scale-invariant evaluation but ensures it is only called after the sequence is re-normalized, keeping it strictly consistent with the objective function.

+softmax_gradient_and_symmetry_refinement
+</NAME>
+
+<DESCRIPTION>
+The proposed optimization refines the sequence search by:
+1.  **Softmax-Weighted Gradient Reduction**: Replaces the local `argmax`-based peak reduction with a more holistic move. It uses a softmax (exponential) weighting of all convolution peaks to calculate a "gradient" of the maximum peak with respect to each sequence element, then reduces the most influential indices.
+2.  **Low-Contribution Boosting**: Similarly uses the gradient information to identify indices that contribute least to the high-value areas of the auto-convolution and increases them to boost the squared sum in the denominator.
+3.  **Symmetry-Preserving Search**: Explicitly tracks if a sequence is symmetric and re-enforces symmetry during most mutations, as symmetric sequences are more stable and typically yield lower auto-convolution peaks.
+4.  **Enhanced Seeding and Multi-Res Scaling**: Adds Gaussian and harmonic initializations and uses a more robust resolution schedule with weighted time shares to focus search on high-resolution refinement.
+5.  **Faster Internal Evaluation**: Uses a scale-invariant metric directly within the search loop to avoid redundant normalization and list conversions.

+<NAME>
+surgical_peak_and_spectral_refinement
+</NAME>
+
+<DESCRIPTION>
+The previous gradient-based approach (using a softmax proxy for the max operator) might be overly 'blurry' for the final refinement stages of the objective $2n \cdot \max(a*a) / (\sum a)^2$. I am proposing the following improvements:
+1. Re-introducing a 'Surgical Peak Reduction' move: This identifies the specific index $i$ that contributes the most to the actual maximum convolution peak $p$ and reduces it. This was a key feature in earlier high-performing versions.
+2. Implementing 'Spectral Smoothing' via FFT: Periodically damping high-frequency components in the frequency domain keeps the sequence smooth, which is critical for avoiding spurious peaks in the auto-convolution.
+3. Refining the search schedule: Allocating more time to intermediate and high resolutions to ensure global shape stability before final local optimization.
+4. Enhancing the 'Compensation Move': Instead of using the softmax gradient, it now identifies the index with the minimum contribution to the convolution peaks and boosts it to increase the $(\sum a)^2$ denominator with minimal impact on the numerator.

+<NAME>
+Optimized_Gradient_Spectral_Search
+</NAME>
+
+<DESCRIPTION>
+This update implements several high-impact improvements to the sequence optimization process:
+1.  **Refined Initialization**: Enhances the `_seed_sequence` with a U-shaped distribution and early symmetry enforcement to provide a more diverse and promising starting pool.
+2.  **Spectral Mutation (FFT)**: Introduces a low-frequency spectral perturbation using `np.fft.rfft`. This ensures that search moves preserve the "smoothness" of the sequence, which is critical for minimizing the auto-convolution peak without introducing high-frequency noise.
+3.  **Full Gradient-Based Sensitivity**: Replaces simple greedy moves with a more principled sensitivity analysis. Using the full objective gradient $g_i$, the search now identifies and adjusts the indices that will most effectively reduce the objective (indices with large positive $g_i$ are decreased, and indices with large negative $g_i$ are increased).
+4.  **Performance Optimization**: Streamlines the `evaluate_sequence` function and the search loop by pre-calculating common gradient terms, allowing for a higher iteration count within the 10-second budget.
+5.  **Multi-Resolution Symmetry Prior**: Enforces symmetry at the beginning of each resolution step, leveraging the fact that symmetric sequences are highly efficient for auto-convolution tasks.

+<NAME>
+sensitivity_driven_multi_peak_optimization
+</NAME>
+
+<DESCRIPTION>
+This update implements several key improvements inspired by the recommendations:
+1.  **Refined Seeding**: Expands `_seed_sequence` diversity with mixed-sine and adaptive power distributions to better explore the starting space.
+2.  **Sensitivity-Based Optimization**: Replaces the single-peak reduction with a "Sensitivity-based Peak Reduction" that uses a softmax-weighted gradient (calculated via convolution) to identify and reduce indices contributing to all high convolution peaks simultaneously.
+3.  **Soft Compensation**: Replaces usage-based compensation with a sensitivity-based version that boosts indices with the least impact on peaks, increasing the denominator more efficiently.
+4.  **Symmetry-Preserving Local Search**: Incorporates logic to detect if a sequence is symmetric and selectively preserve that symmetry during mutations, recognizing that the optimal sequence is likely symmetric.
+5.  **Enhanced Spectral Mutations**: Improves the spectral mutation to specifically perturb low-frequency components while maintaining the low-pass filter effect.
+6.  **Faster Evaluation**: Maintains the fast scale-invariant evaluation found in the current best program to maximize search throughput.

+robust_search_and_seeds
+</NAME>
+
+<DESCRIPTION>
+The optimization goal is to minimize $f(a) = \frac{2n \cdot \max(a * a)}{(\sum a)^2}$ for a nonnegative sequence $a$ of length $n$. To improve the current baseline of 1.72, I am proposing several enhancements:
+
+1.  **Diverse Initial Seeds**: Beyond the current sinusoidal seed, I'll add a constant sequence and more variations of symmetry and frequency to explore the search space more broadly.
+2.  **Symmetry Mutation**: Auto-convolution of a sequence $a$ is related to its shape. Symmetric sequences often yield better (flatter) convolution peaks relative to their sum. I'll add a mutation that averages a sequence with its reflection.
+3.  **Contiguous Block Mutations**: The current search uses scattered perturbations. Contiguous block mutations better preserve and discover "shapes" (low-frequency features) which are crucial for this functional.
+4.  **Refined Upsampling**: Instead of simple repetition, I'll use linear interpolation (upsampling) to refine a discovered shape into a higher-resolution version (up to $n=800$), providing more degrees of freedom for smoothing the convolution peak.
+5.  **Robust Normalization**: Ensuring the sequence remains within a stable numerical range and respects the non-negativity and sum constraints of the objective.
+</DESCRIPTION>

+softmax_gradient_and_spectral_refinement
+</NAME>
+
+<DESCRIPTION>
+Optimizes the coefficient sequence using a Softmax-weighted Sensitivity Gradient approach. This method calculates a 'contribution vector' for all indices relative to the peaks of the auto-convolution, allowing for a more systematic and multi-index reduction of peaks (Gradient Reduction) and boosting of inactive regions (Gradient Boost). Additionally, the spectral mutation is refined to prioritize low-frequency smoothness, and the initial seeding is expanded with power-law distributions which have historically proven effective for this inequality.

+<NAME>
+Surgical_Spectral_Optimization
+</NAME>
+
+<DESCRIPTION>
+Optimized the sequence search by implementing a more robust multi-resolution schedule (128, 256, 512, 768) and a skewed time allocation (10%/15%/25%/50%) to focus on the complex landscape of higher resolutions. Refined the mutation strategy to include a high-beta gradient descent (up to 400) for surgical peak squeezing, a targeted surgical peak reduction move from successful prior runs, and an efficiency-based energy redistribution move. To improve performance, the convolution is calculated once per iteration and a fast evaluation is used, allowing for significantly more iterations within the time budget. Added more diverse seeding options to the spectral generator, including U-shapes and symmetric sines.

+smooth_sensitivity_optimization
+</NAME>
+
+<DESCRIPTION>
+Reallocate budget to higher resolutions where the L-infinity landscape is more complex, implement smoothed gradient-based reduction using the correct sensitivity weighting (grad * seq) for multiplicative updates, and refine the contribution boost move using a surgical efficiency ratio approach. The decay of the mutation strength (sigma) is also adjusted to preserve exploration in later stages of the search.

+<NAME>
+sensitivity_informed_search_refinement
+</NAME>
+
+<DESCRIPTION>
+Optimizes the sequence search by leveraging sensitivity analysis (gradients) across more mutation types. Specifically:
+1.  **Shared Sensitivity Calculation**: Computes the softmax-weighted peak sensitivity (`grad_peak`) once per iteration to be used by multiple mutation strategies.
+2.  **Robust Surgical Reduction**: Targets indices with the highest `grad_peak` (most contribution to all high-convolution peaks) rather than just the single maximum peak.
+3.  **Gradient-Informed Denominator Boost**: Targets indices with the lowest `grad_peak` to increase the sequence sum (denominator) with minimal impact on the convolution peak (numerator).
+4.  **Symmetry-Breaking Jitter**: Introduces a periodic symmetry-breaking mutation to escape local minima in the symmetric subspace, followed by re-symmetrization cycles.
+5.  **Skewed Time Allocation**: Reallocates budget to give more time (60%) to the highest resolution (768), where the $L_\infty$ landscape is most complex.

+annealed_sensitivity_and_skewed_resolutions
+</NAME>
+
+<DESCRIPTION>
+This update implements three key improvements:
+1. **Annealed Sensitivity-Based Mutations**: Replaces the single-index peak reduction and compensation moves with a softmax-weighted gradient approach. A dynamic temperature (beta) scales from 20 to 100 over the search progress, focusing surgical mutations on absolute convolution peaks as the search matures.
+2. **Skewed Time Allocation**: Reallocates search time from a uniform split to a 15%/25%/60% split across the three resolutions (256, 512, 768). High-resolution refinement of the L-infinity norm requires significantly more iterations than initial skeleton shaping.
+3. **Power-Law Seeding**: Introduces symmetric and asymmetric power-law initializations ($x^{-0.5}$), which are theoretically near-optimal for flattening auto-convolutions.
+4. **Symmetry-Preserving Cycles**: Ensures that mutations on symmetric sequences are re-symmetrized, preventing the search from accidentally drifting into less efficient asymmetric subspaces while allowing for symmetry breaking in the final 5% of moves.

+smoothed_gradient_and_skewed_res
+</NAME>
+
+<DESCRIPTION>
+This update implements several refinements to the search strategy based on optimization principles for high-resolution sequences:
+
+1.  **Skewed Resolution Time Allocation**: Reallocates the search budget to spend significantly more time (55%) on the final 768-resolution stage, where the $L_\infty$ landscape is most rugged.
+2.  **Gaussian-Smoothed Gradient Updates**: Applies a 3-point local smoothing to the softmax-gradient before updates. This prevents the formation of high-frequency "spikes" that lead to new convolution peaks, maintaining a more robust sequence profile.
+3.  **Efficiency-Informed Denominator Boost**: Targets indices with the lowest "peak sensitivity" (gradient) for sequence amplification. This increases the sequence sum (the denominator) with minimal impact on the auto-convolution maximum (the numerator).
+4.  **Smoothed Block Perturbations**: Replaces sharp block changes with Gaussian-windowed perturbations to preserve the spectral integrity of the sequence.
+5.  **Multi-strategy Mutation Balance**: Shifts the mutation probability distribution to emphasize gradient-informed surgical moves while retaining stochastic exploration (block moves and jitter) to escape local optima.

+<NAME>
+Refined_gradient_search_with_skewed_time
+</NAME>
+
+<DESCRIPTION>
+This update improves the search performance through several targeted optimizations:
+1. **Skewed Time Allocation**: Reallocates budget to give more search time to the highest resolution ($N=768$), where the landscape is most complex.
+2. **Sharpened Gradient Mutations**: Applies local Gaussian-like smoothing to gradient-based masks to prevent the formation of high-frequency "spikes" and uses multiplicative sensitivity (`grad * seq`) to target peak reductions more effectively.
+3. **Dynamic Strategy Transition**: Prioritizes gradient-informed local refinement over global stochastic moves as the budget progresses.
+4. **Symmetry Subspace Preservation**: Actively maintains symmetry if the current sequence is already symmetric, preventing the search from wasting time in asymmetric regions unless intentionally directed.
+5. **Numerical Stability**: Enhances softmax sharpening (higher beta) and normalization to ensure stable convergence toward the theoretical $1.57$ limit.

+<NAME>
+optimized_search_with_peak_reduction
+</NAME>
+
+<DESCRIPTION>
+Optimized the search by:
+1. Speeding up the `evaluate_sequence` function while maintaining all safety checks.
+2. Introducing a `_fast_eval` function for use within the search loop to avoid repeated list conversions and safety overhead.
+3. Implementing a multi-resolution search strategy (upsampling from 128 to 768) to explore shapes more efficiently.
+4. Adding a targeted 'peak reduction' mutation that identifies and reduces the elements contributing most to the autocorrelation peak.
+5. Refining the seed generation and mutation probabilities to favor asymmetric shapes and more effective local search.

+</NAME>
+
+<DESCRIPTION>
+This update implements several strategic improvements to the search process:
+1. **Skewed Resolution Budgeting**: Reallocates more runtime to the highest resolution (768), where the convolution landscape is most rugged and convergence takes more iterations.
+2. **Surgical Peak Reduction**: Adds a mutation move that targets the specific indices in the sequence that contribute most to the current auto-convolution maximum, allowing for more precise 'flattening' of peaks.
+3. **Smoothed Gradient Mutations**: Applies a local 3-point smoothing to gradient updates to prevent high-frequency noise that often triggers new, unintended convolution spikes.
+4. **Efficiency-Informed Scaling**: Refines the denominator-boosting move to specifically target indices with the lowest peak sensitivity (gradient), maximizing the increase in the sequence sum while minimizing the impact on the numerator.
+5. **Dynamic Beta Scheduling**: Adjusts the softmax temperature (beta) more aggressively over time to transition from global shape optimization to pinpoint peak suppression.

+<NAME>
+Targeted_Multi_Action_Optimization
+</NAME>
+
+<DESCRIPTION>
+This update refines the search strategy by incorporating four key improvements:
+1. **Differentiable Softmax Gradient**: Replaces the heuristic multi-peak reduction with a softmax-weighted gradient proxy. This provides a smoother, more globally-informed update direction that considers all high-convolution peaks simultaneously.
+2. **Skewed Resolution Time Allocation**: Reallocates the budget to favor the highest resolution (768), providing 60% of the time to the most rugged landscape where fine-tuning is most difficult.
+3. **Momentum-Accelerated Search**: Introduces a momentum term for gradient updates to traverse plateaus more effectively and avoid oscillating in tight valleys.
+4. **Gradient-Informed Denominator Boosting**: Refines the "compensation" mutation to target indices with the lowest gradient (efficiency ratio), increasing the sequence sum (the denominator) while minimizing the impact on the auto-convolution maximum.

+<NAME>
+surgical_gradient_and_timing
+</NAME>
+
+<DESCRIPTION>
+This update implements five key optimizations to improve the sequence minimization:
+1. **Skewed Resolution Time Allocation**: Reallocates the search budget to provide significantly more time (50%) to the highest resolution ($n=768$), where the landscape is most complex.
+2. **Surgical Peak-Contribution Targeting**: Adds a mutation that identifies the exact maximum convolution peak and reduces the sequence indices contributing most to it.
+3. **Gaussian-Smoothed Gradient Updates**: Applies a local smoothing operator to the softmax gradient to prevent high-frequency spikes and ensure robust updates.
+4. **Efficiency-Ratio Boosting**: Refines the denominator-boosting mutation to target indices with the absolute minimum impact on the convolution peaks, more effectively lowering the objective ratio.
+5. **Annealed Symmetry Enforcement**: Increases the probability of enforcing symmetry as the search progresses, leveraging the spectral advantages of symmetric sequences in auto-convolution tasks.

+power_law_seeds_and_relative_gradient_with_smoothing
+</NAME>
+
+<DESCRIPTION>
+Incorporate several refinements based on expert knowledge:
+1.  **Enhanced Seeding**: Added Power-Law and Symmetric Power-Law seeds, as these are known to yield flatter auto-convolutions and are theoretical candidates for minimizing the objective.
+2.  **Skewed Resolution Time Allocation**: Allocated search time non-linearly (10%, 20%, 70%) for resolutions 256, 512, and 768, respectively, to focus the search on the more complex high-resolution landscape.
+3.  **Relative Gradient Updates**: Replaced point-wise sensitivity updates with a more principled "Relative Gradient" derived from the log-objective. This approach surgicaly targets indices that improve the efficiency ratio (reducing the auto-convolution peak while preserving the sequence sum).
+4.  **Gaussian Smoothing of Mutations**: Applied a 3-point Gaussian blur to the gradient-based mutation masks to prevent the introduction of high-frequency spikes, maintaining the spectral integrity of the sequence.
+5.  **Annealed Symmetry Enforcement**: Increased the probability of symmetry enforcement towards the end of the search to take advantage of the search-space reduction.

+efficiency_gap_gradient_and_skewed_scheduling
+</NAME>
+
+<DESCRIPTION>
+This update refines the search strategy in several key ways to better navigate the rugged L-infinity landscape of the auto-convolution objective:
+1. **Surgical Efficiency-Gap Gradient**: Replaces the previous "Unified Gradient Step" with a more robust multiplicative update based on the dimensionless efficiency gap. This gap measures the difference between an index's relative contribution to the convolution peaks and its relative contribution to the sequence sum. A positive gap identifies "inefficient" indices that should be reduced.
+2. **Hard-Peak Component**: Incorporates a "surgical" component into the softmax weights that directly targets the absolute maximum peaks of the convolution, supplementing the smooth proxy gradient.
+3. **Multi-Resolution Timing Refinement**: Reallocates search time from the intermediate 384 resolution to maximize the time spent on high-resolution (768) refinement, where flattening the final convolution spikes is most difficult.
+4. **Adaptive Spectral Filtering**: Adjusts the FFT low-pass cutoff dynamically based on search progress, allowing for broad global shaping early on and tighter local smoothing in the final stages.
+5. **Annealed Symmetry Enforcement**: Increases the probability of staying in the symmetric search subspace as the search nears the deadline, reflecting the observed symmetry in near-optimal solutions.

+dual_action_and_skewed_res
+</NAME>
+
+<DESCRIPTION>
+Optimized the search strategy by:
+1.  **Skewing Time Allocation**: Increased the search time for the highest resolution ($n=768$) to 70% of the total budget, as the $L_\infty$ landscape of the auto-convolution is most rugged at higher resolutions.
+2.  **Implementing "Dual-Action" Mass Transfer**: Replaced the "Surgical Peak Reduction" with a mutation that moves mass from high-impact indices (those contributing most to the convolution peak) to low-impact indices (those with minimum peak sensitivity). This directly optimizes the peak-to-sum ratio while preserving the sequence sum.
+3.  **Refining Efficiency-Based Boost**: Updated the denominator-boosting mutation to target the most "efficient" indices (those with the lowest gradient) using a scaling approach, ensuring the denominator increases with minimal impact on the convolution maximum.
+4.  **Tuning Learning Rate Decay**: Moderated the learning rate decay (from 0.5 to 0.7) to allow the search to explore promising neighborhoods more thoroughly before resetting.

+<NAME>
+gradient_enhanced_search
+</NAME>
+
+<DESCRIPTION>
+The optimization of the nonnegative step-function coefficient sequence is improved by:
+1.  **Diverse Initializations**: In addition to sine-based sequences, we now include random uniform and U-shaped initializations to explore a wider range of potential shapes.
+2.  **Gradient-Based Peak Reduction**: The auto-convolution's maximum value is the bottleneck for the objective function. We derive the gradient of the objective with respect to each sequence element and use it to perform a targeted "peak reduction" move. This move specifically adjusts elements contributing to the highest peak in the convolution.
+3.  **Adaptive Hill-Climbing**: A more structured local search that combines gradient descent, random block perturbations, and smoothing, while maintaining the best sequence found.
+4.  **Refined Mutation Logic**: Balancing aggressive exploration (random perturbations) with fine-tuning (gradient steps) and maintaining the sequence's scale for numerical stability.

+<NAME>
+log_grad_refinement
+</NAME>
+
+<DESCRIPTION>
+Optimized the sequence search using a scale-invariant log-gradient approach, enhanced power-law seeding, and adaptive refinement.
+1. **Diverse Power-Law Seeding**: Added explicit power-law and Salem-Zygmund-like initializations, which are known strong candidates for minimizing the autoconvolution-to-sum ratio.
+2. **Log-Gradient Optimization**: Replaced the direct gradient with the gradient of the log-objective $\nabla \ln(2n \cdot P / S^2) = \frac{\nabla P}{P} - \frac{2 \nabla S}{S}$. This is scale-invariant and numerically more stable during refinement.
+3. **Adaptive Mutation Strategy**: Refined the surgical peak reduction and efficiency boost mutations to use the calculated peak sensitivity (gradient), allowing more targeted updates.
+4. **Symmetry-Aware Search**: Transitioned symmetry from a random mutation to a deterministic constraint as the search nears completion (progress > 0.8), effectively focusing the search space in the final optimization phase.
+5. **Numerical Stability**: Improved `_normalize` and `_fast_val` consistency and used `mode='valid'` for gradient convolutions to improve efficiency and correctness.

+<NAME>
+Refined_Efficiency_Gap_and_Skewed_Refinement
+</NAME>
+
+<DESCRIPTION>
+Optimized the search strategy with the following improvements:
+1.  **Refined Seeding**: Tightened the power-law exponent range in `_seed_sequence` to focus on values near $p=0.5$, which are theoretically closer to the optimal decay for minimizing the $L_2$ convolution maximum relative to the $L_1$ sum.
+2.  **Surgical Efficiency-Gap Gradient Move**: Replaced the dual-step reduction/boost gradient moves with a unified "Efficiency-Gap" mutation. This calculates the relative sensitivity of each index to the objective function, identifying "inefficient" indices (contributing more to convolution peaks than the sequence sum) and "efficient" ones. It includes an optional "surgical" weighting component that focuses specifically on indices contributing to the absolute global maximum of the convolution.
+3.  **Enhanced Mutation Smoothing**: Implemented a 5-point Gaussian-like smoothing kernel for mutation masks to prevent high-frequency spikes that create new convolution peaks, maintaining the spectral smoothness of high-performing sequences.
+4.  **Skewed Time Allocation**: Shifted more of the computational budget to the final resolution ($n=768$) to allow for finer local refinement in the most complex search landscape.
+5.  **Symmetry-Aware Mutators**: Integrated symmetry preservation directly into the gradient mutation step to ensure that the search efficiently explores the symmetric subspace where optimal solutions are expected to lie.

+surgical_peak_and_smooth_gradient
+</NAME>
+
+<DESCRIPTION>
+Optimizes the sequence search by:
+1. Refining the `_spectral_seed` to prioritize power-law shapes near the theoretical optimum ($p \approx 0.5$).
+2. Increasing the initial seed pool to 40 for broader exploration.
+3. Stabilizing the gradient-based moves by smoothing the calculated gradient and using a more robust softmax `beta`.
+4. Implementing a "Surgical Hard-Peak" mutation that identifies the specific indices contributing to the global convolution maximum and reduces them proportionally.
+5. Annealing the symmetry constraint more strictly as the search progresses.
+6. Ensuring momentum-based updates are scale-appropriate and zero-sum preserving.

+<NAME>
+targeted_refinement_and_smoothing
+</NAME>
+
+<DESCRIPTION>
+Optimizes the search process by implementing four key improvements:
+1. **Consolidated Gradient Dynamics**: Normalizes the softmax weights and applies a smoothing operator (3-point rolling average) to the calculated gradient to prevent high-frequency spikes and ensure more robust sequence updates.
+2. **Hard-Peak Mutation**: Introduces a surgical mutation that identifies the single highest contributor to the absolute global convolution maximum and reduces it, complementing the probabilistic softmax approach.
+3. **Adaptive Beta & Skewed Schedule**: Increases the softmax beta to focus more sharply on peaks as the search progresses and further skews the resolution time shares to provide the 768-resolution phase with 70% of the total budget.
+4. **Refined Efficiency Boost**: Adjusts the efficiency-targeted mutation to increase values in regions with minimal impact on the peak, thereby increasing the denominator of the objective function more effectively.

+<NAME>
+Surgical_Peak_Targeting_and_Resolution_Scaling
+</NAME>
+
+<DESCRIPTION>
+Optimizes the step-function coefficient sequence by refining the gradient-based mutation and increasing the resolution of the search.
+1. **Adaptive Resolution Transition**: Transitions through five resolutions (256, 384, 512, 640, 768) with a skewed time allocation (5%/10%/20%/25%/40%) to allow for surgical refinement at the highest granularity where the most complex convolution peaks emerge.
+2. **Surgical Peak Targeting (Unified Gradient Step)**: Corrects the gradient-based mutation by using the theoretical gradient of the log-objective $\ln(J) \propto \ln(\max c) - 2\ln(\sum a)$. The update uses a softmax-weighted proxy of the convolution peaks and applies a spatially smoothed exponential update to both reduce peak-contributing indices and boost "efficient" indices simultaneously.
+3. **Enhanced Gradient Smoothing**: Applies a 5-point Gaussian-like kernel `[0.06, 0.24, 0.4, 0.24, 0.06]` to the calculated gradient mask to prevent the introduction of high-frequency spikes and maintain the spectral smoothness of the sequence.
+4. **Refined Schedule**: Adjusts the softmax sharpness ($\beta$) and mutation intensity ($\sigma$) schedules to favor exploration early on and deterministic local refinement as the deadline approaches.

+improved_seeding_and_gradient_search
+</NAME>
+
+<DESCRIPTION>
+Optimizes the search for the AC inequality by:
+1.  **Refining Seeding**: Adds a power-law seed (proportional to $(i+1)^{-0.5}$) known to be effective for this class of problem.
+2.  **Skewed Time Allocation**: Adjusts resolution time shares (10%, 20%, 70%) to give more budget to the final $n=768$ refinement stage, where local peaks are harder to flatten.
+3.  **Smoothed Relative-Gradient Move**: Replaces separate reduction and boost moves with a unified gradient step based on the relative log-objective gradient. It applies a 3-point spatial smoothing to the gradient mask to prevent the creation of high-frequency spikes in the sequence, which typically trigger new convolution peaks.
+4.  **Annealed Symmetry Enforcement**: Increases the probability of symmetry enforcement as the search progresses to focus the search on the symmetric subspace likely to contain the global optimum.

+<NAME>
+refined_natural_gradient_and_seeding
+</NAME>
+
+<DESCRIPTION>
+This update refines the search strategy by:
+1.  **Enhancing Seeding**: Focusing on power-law exponents ($p \in [0.42, 0.58]$) and adding structured quadratic/sine seeds to provide a better initial landscape.
+2.  **Unified Natural Gradient**: Improving the softmax-weighted gradient move to use "sensitivity" (grad * seq) as the prioritization metric, which more effectively identifies where multiplicative reductions will lower the $L_\infty$ convolution norm.
+3.  **Broadened Peak Pressure**: Generalizing the targeted reduction move to handle top-contributing indices for convolution maxima more greedily.
+4.  **Multi-Resolution Smoothing**: Introducing a smoothing mutation to help the sequence converge toward the optimal "envelope" during the high-resolution refinement phases.
+5.  **Tighter Progress Schedule**: Slightly accelerating the convergence schedule and increasing the reliance on symmetry at high progress, where optimal sequences for the AC inequality are expected to be symmetric.

+precision_gradient_and_multi_peak_targeting
+</NAME>
+
+<DESCRIPTION>
+This update refines the optimization search by incorporating several strategic improvements:
+1.  **Surgical Softmax Gradient**: Enhances the gradient-based peak reduction by increasing the softmax temperature (beta) more aggressively as the search progresses ($40 + 360 \cdot \text{progress}^{1.4}$) and using `mode='valid'` for more efficient sensitivity calculations.
+2.  **Multi-Peak Pressure Strategy**: Replaces single-peak targeting with a move that identifies all convolution peaks within 1.5% of the maximum, then stochastically selects contributors to reduce.
+3.  **Adaptive Efficiency Boost**: Refines the "Efficiency Boost" mechanism to scale up non-contributing sequence elements more aggressively as time passes.
+4.  **Deterministic Symmetry Late-Phase**: Transitions symmetry preservation from a stochastic process to a deterministic constraint when `progress > 0.8`.
+5.  **Multi-Resolution Seeding**: Consolidates the initial seeding and resolution scaling logic.

+<NAME>
+Surgical_MultiRes_Optimization
+</NAME>
+
+<DESCRIPTION>
+Optimizing the coefficient sequence by implementing three key improvements:
+1. **Enhanced Resolution Schedule**: Starts at $n=128$ to rapidly converge on the global sequence "envelope" before refining at higher resolutions (256, 512, 768).
+2. **Multiplicative "Peak Pressure" Updates**: Introduces a targeted move that identifies the maximum convolution peak and reduces the contributing elements $a_i, a_j$ proportionally to their product $a_i \cdot a_j$, which is more surgical than uniform gradient moves.
+3. **Log-Gradient Elasticity Stability**: Refines the "Efficiency-Gap" update by using a stabilized softmax proxy and a more accurate relative gradient (elasticity) calculation to focus refinement only on indices that disproportionately contribute to peaks versus the total sum.
+4. **Improved Seeding**: Expands the initial search to include resolution $n=128$ and increases the number of random trials to find a better global starting point.

+<NAME>
+surgical_gap_and_multi_res
+</NAME>
+
+<DESCRIPTION>
+Refine the search by introducing a surgical "Contribution Gap" gradient move that uses a higher softmax beta for peak targeting. The multi-resolution schedule is expanded to include a lower resolution (128) for faster shape discovery, and deterministic symmetry is enforced more strictly in the final refinement phase. Seeding is also enhanced with more frequent power-law and random spike initializations to better explore the search space.

+<NAME>
+surgical_gradient_and_peak_to_gap
+</NAME>
+
+<DESCRIPTION>
+Optimizes the sequence search by implementing several key improvements:
+1.  **Windowed Power-Law Seeding**: Refines the power-law seeds by applying a small taper to the edges, providing a smoother initial convolution profile.
+2.  **Peak-to-Gap Mass Transfer**: Replaces the scattered perturbation with a surgical move that identifies indices contributing most to convolution peaks and shifts their mass to indices with minimal contribution.
+3.  **High-Beta Unified Gradient Step**: Improves the gradient move with log-sum-exp numerical stability and a much higher beta range (up to 500) to isolate and minimize absolute peaks as the search progresses.
+4.  **Efficiency Gap Update**: Replaces the discrete mask update with a continuous multiplicative update based on the "Relative Efficiency Gap," which directly compares an index's relative contribution to the peaks versus its contribution to the sequence sum.
+5.  **Deterministic Symmetry Hardening**: Enforces symmetry more strictly during the final resolution stage (n=768) as the deadline approaches to concentrate the search on the most relevant part of the space.

+<NAME>
+Refined_Gradient_and_Seeding
+</NAME>
+
+<DESCRIPTION>
+Optimizes the step-function coefficient sequence search with the following improvements:
+1.  **Coupled Peak-to-Gap Mass Transfer**: Modifies the precision softmax gradient move to simultaneously reduce mass at peak-contributing indices and increase mass at trough-contributing indices, directly improving the "water-filling" efficiency of the sequence.
+2.  **Annealed High-Beta Softmax**: Increases the maximum beta for softmax weights from 400 to 550, enabling a sharper approximation of the $L_\infty$ maximum in the final resolution stage.
+3.  **Tapered Power-Law Seeding**: Refines the initial power-law seeds with a tighter $p$ range (0.46–0.54) and introduces a slight Tukey-like taper at the sequence edges to prevent high-frequency artifacts.
+4.  **Deterministic Symmetry Hardening**: Enforces 100% symmetry for the final 18% of the search budget, concentrating precision moves on the symmetric subspace known to contain optimal solutions.
+5.  **Multi-Resolution Timing**: Re-allocates time shares to give nearly 60% of the total budget to the highest resolution ($n=768$) refinement.

+<NAME>
+high_beta_symmetry_ladder
+</NAME>
+
+<DESCRIPTION>
+This update implements several key improvements based on the most successful prior strategies (reaching values around 1.60-1.61):
+1.  **Symmetric Power Law Seeding**: Reintroduces symmetric power-law initializations ($(i+1)^{-p} + (n-i)^{-p}$), which are near-optimal for this objective.
+2.  **High-Beta Softmax Gradient**: Replaces the simple single-index peak reduction with a softmax-weighted gradient approximation. This move targets all indices contributing to the highest convolution peaks simultaneously, using a sharpening $\beta$ (up to 500) as the search progresses.
+3.  **Deterministic Symmetry Hardening**: Given the symmetry of the optimal solution, the search increasingly focuses on the symmetric subspace, enforcing strict symmetry (`seq = (seq + seq[::-1]) / 2.0`) in the final resolution stage ($n=768$).
+4.  **Revised Resolution Ladder**: Skews the time-budget distribution toward higher resolutions ($n=512, 768$) where the most significant objective improvements occur.
+5.  **Coupled Peak-to-Gap Mass Transfer**: Implements a "Efficiency Boost" mutation that identifies indices contributing least to the convolution and increases their mass, effectively flattening the overall profile.

+<NAME>
+high_beta_mass_transfer
+</NAME>
+
+<DESCRIPTION>
+This update introduces three key improvements to the search process:
+1. **Surgical Precision with High-Beta Softmax**: Increases the softmax $\beta$ parameter from 200 to 500, sharpened by a quadratic progress curve. This allows the gradient descent to focus specifically on the most problematic convolution peaks as the search approaches higher resolutions.
+2. **Coupled Peak-to-Gap Mass Transfer**: Replaces the independent efficiency boost with a coordinated "water-filling" mutation. This move identifies indices contributing most to the maximum convolution peaks and directly transfers mass to indices that contribute least, maintaining the sequence sum while simultaneously reducing peaks and filling gaps.
+3. **Deterministic Symmetry Hardening**: Gradually transitions from stochastic symmetry preservation to deterministic symmetry enforcement as the search reaches the final resolution. Since the optimal AC inequality sequences are known to be symmetric, this concentrates the final 15% of the budget on refining the most promising region of the search space.
+4. **Numerical Stability Refinements**: Implements clipped log-sum-exp style weighting for the softmax gradients and uses `mode='valid'` for faster, more memory-efficient gradient calculation.

+<NAME>
+gradient_and_diversity_enhancement
+</NAME>
+
+<DESCRIPTION>
+This edit improves the search strategy by:
+1. Enhancing the `_seed_sequence` with more diverse starting shapes and more frequent symmetry enforcement.
+2. Expanding the initial multi-start pool to cover more lengths and trials.
+3. Replacing the localized "Peak Reduction Move" with a more global "Gradient Step" based on the derivative of the objective function. This gradient helps to systematically "flatten" the convolution peak.
+4. Adding a symmetry-enforcement move in the search loop to exploit the likely symmetry of optimal solutions.
+5. Refining the mutation probabilities and adaptive learning rate for the gradient step.

+<NAME>
+Surgical_Peak_Refinement
+</NAME>
+
+<DESCRIPTION>
+This update implements several high-precision optimization strategies for the AC inequality:
+1.  **Windowed and Symmetric Seeding**: Refines initializations by adding symmetric power-law distributions and applying a soft tapering window to reduce edge artifacts.
+2.  **Annealed High-Beta Gradient Descent**: Increases the softmax beta from 140 to 500 as search progresses, sharpening the gradient's focus on the absolute convolution maximum.
+3.  **Coupled Peak-to-Gap Mass Transfer**: Introduces a new mutation that directly transfers mass from indices contributing to convolution peaks to those in convolution "valleys," improving sequence efficiency.
+4.  **Deterministic Symmetry Hardening**: Implements a strict symmetry constraint in the final search stages (progress > 0.9) to concentrate the budget on the most promising symmetric subspace.
+5.  **Fast Scale-Invariant Evaluation**: Replaces slow list-based evaluations with direct NumPy-based calculations to increase the number of iterations within the time budget.

+coupled_peak_to_gap_and_hardmax_gradient
+</NAME>
+
+<DESCRIPTION>
+This update refines the optimization strategy by introducing a 'Coupled Peak-to-Gap Migration' move and an improved 'Super-Sharpened Gradient' move.
+1.  **Super-Sharpened Gradient (m_type < 0.65)**: Increases the softmax parameter $\beta$ up to 600 in the final stage for more surgical dampening of convolution peaks. It uses the shift-invariance property $\exp(\beta(C - \max(C)))$ to maintain numerical stability at high $\beta$ levels.
+2.  **Coupled Peak-to-Gap Migration (m_type < 0.85)**: Instead of independent peak reduction and efficiency boosting, this move directly identifies indices contributing most to the maximum autocorrelation and shifts their mass to indices that contribute the least. This 'water-filling' approach directly addresses the objective function's trade-off between peak height and total mass.
+3.  **Deterministic Symmetry Hardening**: In the final phase (progress > 0.85), the algorithm now deterministically enforces symmetry and non-negativity to concentrate search power on the likely optimal symmetric manifold.
+4.  **Smarter Gradient Logic**: The gradient move now uses a normalized sensitivity proxy to better balance local dampening versus global mass preservation.

+Super_Sharpened_Gradient_and_Coupled_Migration
+</NAME>
+
+<DESCRIPTION>
+This update pushes the optimization further by implementing the "Super-Sharpened Gradient" and "Coupled Peak-to-Gap Mass Migration" strategies. Specifically:
+1.  **Increased Softmax Beta**: The peak-targeting softmax sharpness ($\beta$) is increased from 120 to 500, allowing for more surgical reduction of the convolution peaks as the search progresses.
+2.  **Coupled Mass Migration**: Replaces independent reduction/boost moves with a "water-filling" approach that transfers mass directly from indices contributing to peaks (high sensitivity) to indices with the lowest peak contribution (low gradient).
+3.  **Refined Gradient Calculation**: Implements the exact derivative of the objective function for high-resolution refinement.
+4.  **Optimized Schedule and Resolutions**: Adds a 128-resolution stage and reallocates 65% of the time to the 768-resolution phase for deeper exploitation.
+5.  **Deterministic Symmetry Hardening**: Progressively increases symmetry enforcement, culminating in deterministic symmetry for the final 15% of the search to effectively halve the search space.
+6.  **Selective Spectral Damping**: Replaces blanket low-pass filtering with frequency-selective damping to preserve the global envelope while suppressing high-frequency jitter.

+<NAME>
+super_sharpened_gradient_and_mass_migration
+</NAME>
+
+<DESCRIPTION>
+Optimizes the search by implementing three main improvements:
+1.  **Unified Super-Sharpened Gradient**: Replaces the one-sided gradient reduction with a two-sided (reduction/boost) move that uses the relative gradient of the log-objective. It also increases the softmax parameter $\beta$ up to 400 as the search progresses, allowing surgical targeting of indices contributing to the peak convolution values.
+2.  **Coupled Peak-to-Gap Mass Migration**: Replaces the independent "Efficiency Boost" with a mass transfer move that directly identifies peak-contributing indices and moves a portion of their mass to under-utilized indices, preserving the sequence sum while directly lowering the max convolution.
+3.  **Late-Stage Symmetry Hardening**: Enforces deterministic symmetry in the final resolution phase (after 88% progress) to concentrate search resources on the most promising (and historically optimal) symmetric region of the search space.
+4.  **Refined Spectral Mutation**: Adds selective damping of high-frequency components while perturbing low-frequency global shapes to maintain spectral integrity.

+super_sharpened_momentum_gradient
+</NAME>
+
+<DESCRIPTION>
+This update implements a more aggressive and targeted search strategy:
+1.  **Momentum-based High-Beta Gradient Step**: Replaces the static gradient move with a momentum-based update that uses a "Super-Sharpened" softmax ($\beta$ up to 500) to isolate peak-contributing indices surgically.
+2.  **Coupled Peak-to-Gap Mass Migration**: Introduces a water-filling mutation that directly transfers mass from indices responsible for convolution peaks to indices that are under-utilized, maintaining the sequence sum while directly lowering the max convolution.
+3.  **Deterministic Symmetry Hardening**: Enforces symmetry more strictly as the search progresses toward the final resolution and the deadline, reflecting the known symmetry of optimal autocorrelation sequences.
+4.  **Numerical Stability**: Uses log-space weight clipping and normalized sensitivity vectors to ensure stable updates even with very high softmax temperatures.
+5.  **Gradient Smoothing**: Applies a light smoothing kernel to the gradient updates to maintain spectral integrity and avoid high-frequency "jitter" that can occur at high resolutions.

+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+This analysis of the program evaluation results for the AlphaEvolve AC inequality task examines the transition from initial stochastic searches to the high-performing multi-resolution gradient-enhanced strategies.
+
+### Successful Algorithmic Patterns
+
+*   **Multi-Resolution Resolution Scaling**: The most successful programs (Gen 5 and Gen 9, both achieving the best score of **-1.63**) utilize a progressive upsampling strategy. They start with a coarse resolution (e.g., $n=128$) to establish a global shape and iteratively interpolate to higher resolutions ($n=256, 512, 768$). This allows the search to avoid high-dimensional local minima by refining an already optimized low-frequency structure.
+*   **Targeted Peak-Reduction Heuristics**: Moving beyond random mutations, the best program (Gen 9) and Gen 5 implemented a "Peak Reduction" move. This logic identifies the maximum convolution index ($p = \text{argmax}(\text{conv}(s, s))$), calculates which sequence indices $i$ contribute most to that specific peak ($\text{contrib} = s[i] \cdot s[p-i]$), and specifically reduces those elements. This targeted exploitation led to the score improvement from **-1.72** (Gen 0) to **-1.63** (Gen 9).
+*   **Symmetry and Shape-Based Initializations**: Utilizing specific seeds rather than pure noise significantly improved starting points. Gen 4 used Beta-distribution polynomial shapes to achieve an objective of **1.75**, while the current best program (Gen 9) uses a mix of sinusoidal, Gaussian, and power-law seeds combined with symmetry enforcement (averaging a sequence with its reverse).
+
+### Ineffective Approaches
+
+*   **Pure Gradient-Based Optimization on Non-Smooth Surfaces**: Programs that relied solely on softmax or $L_p$-norm approximations to differentiate the maximum convolution value (Gen 1 and Gen 2) failed completely (score **0.0**). Feedback suggests these approaches suffered from numerical instability and high sensitivity to the non-differentiable $L_\infty$ operator in the convolution peak.
+*   **Lack of Robust Dependency Management**: Several theoretically sound programs (Gen 7 and Gen 8) failed validation (score **0.0**) due to simple implementation errors, such as missing `numpy` or `time` imports. This highlights that even sophisticated spectral or multi-scale logic is ineffective without basic execution stability.
+*   **Fixed-Length Search**: Early programs (Gen 1) that attempted to optimize only at the target length of 768 struggled to find global minima compared to those that used dynamic upsampling (Gen 3, Gen 9).
+
+### Implementation Insights
+
+*   **Heuristic Local Search vs. Analytic Gradients**: The current best program (Gen 9) succeeds by using "gradient-informed" heuristics (like the Peak Reduction move) rather than formal backpropagation. It uses a `sigma` that decays over time (`0.15 * (1.0 - elapsed/budget)`) to transition from exploration to fine-tuning.
+*   **Dynamic Interpolation for Upsampling**: Successful programs use `np.interp` to translate optimized sequences from one resolution to the next. This ensures the "energy" and shape of the sequence are preserved across the $n=128$ to $n=768$ transition.
+*   **Normalization and Clipping**: The best program (Gen 9) maintains a stable search via a `_normalize_scale` function that clips values to be non-negative and scales them such that the sum equals the sequence length. This prevents the objective function (ratio of max convolution to squared sum) from diverging due to scale shifts.
+
+### Performance Analysis
+
+*   **Score Plateau at 1.63**: Both Gen 5 and Gen 9 reached an objective value of **1.63**, suggesting that the combination of multi-resolution scaling and peak-targeted mutation has reached a localized optimal frontier for this search budget.
+*   **Impact of Upsampling**: Gen 0 (single resolution) achieved **1.72**, whereas Gen 3 (adaptive upsampling) achieved **1.66**. The progression shows that resolution refinement is responsible for approximately a 5% improvement in the objective value.
+*   **Efficiency vs. Sequence Length**: Gen 6 achieved a strong score of **-1.72** at only length 512. However, the best programs (Gen 5, 9) demonstrate that utilizing the full available length (768) is necessary to reach the **1.63** threshold, as the $2n$ factor in the objective function $2n \cdot \max(b) / (\sum a)^2$ is balanced by the increased smoothing potential of larger sequences.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+Based on the success of Gen 9 and the identified algorithmic patterns, here are five actionable recommendations for future program mutations:
+
+1.  **Distributed Peak-Reduction and Compensation**: Enhance the current "Peak Reduction" move by targeting not just the single highest-contributing index, but a neighborhood of indices contributing to the top $k$ peaks of the convolution. Simultaneously, implement a "Compensation" step that slightly increases the values of indices that contribute the least to the convolution peaks; this raises the total sum ($\sum s$) without increasing $\max(\text{conv}(s, s))$, directly improving the objective ratio.
+
+2.  **Frequency-Domain (FFT) Mutations**: Since low-frequency structures (sinusoids, Gaussians) are more effective than high-frequency noise, implement mutations in the spectral domain. By applying small perturbations to the low-frequency components of the sequence's FFT and then transforming back, the search can explore smooth variations that preserve the global shape and "energy" distribution, which is less likely to create the sharp peaks that degrade the objective score.
+
+3.  **Active Symmetry Enforcement**: While the current program uses symmetry in seeds, it does not maintain it during the mutation phase. Implement an "Enforce Symmetry" mutation that replaces a sequence with its average and its reverse ($s_{new} = (s + \text{reverse}(s)) / 2$). Given the self-convolution nature of the task, symmetric sequences often produce more predictable convolution profiles, making the search for a global minimum more stable and constrained.
+
+4.  **Convergence-Triggered Resolution Scaling**: Instead of fixed time-slices for each resolution (128, 256, 512, 768), implement an adaptive schedule that triggers upsampling only when the objective value fails to improve by a certain epsilon over a set number of iterations. This ensures the program spends more time fine-tuning at the highest resolution ($n=768$), where the search space is largest and most sensitive, rather than being forced to move on by a rigid clock.
+
+5.  **Targeted Coordinate Descent for Fine-Tuning**: In the final resolution phase, replace random scattered perturbations with a targeted coordinate descent on the "hotspots." Identify the indices $i$ that contribute to the convolution values within 95% of the maximum peak; perform small, deterministic line-searches (gradient-free) on these specific values to minimize the peak. This transition from stochastic search to local optimization is crucial for breaking the 1.63 plateau.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Annealed High-Beta Softmax Gradient Weighting:** The most successful programs, led by the **Current Best (Gen 72, Score 1.60)** and reinforced by **Gen 94 (1.61)** and **Gen 96 (1.61)**, utilize a softmax-weighted gradient move. By applying a high $\beta$ (Gen 72 uses $\beta$ increasing from 30 to 200), the algorithm identifies specific sequence indices that contribute most to the maximum convolution value. This allows for surgical dampening of peaks rather than stochastic noise.
+*   **Multi-Resolution Resolution Ladders with Time-Budgeting:** Consistency in achieving scores near 1.60 is driven by a resolution-climbing strategy (e.g., $128 \to 256 \to 512 \to 768$). **Gen 72** allocates specific time shares (10%, 25%, 50%, 100%) to these scales, ensuring the global "envelope" is found at low resolution before high-frequency refinement. **Gen 93 (1.71)** and **Gen 95 (1.75)** also used multi-resolution but achieved worse scores, indicating that the transition and mutation intensity at the final $n=768$ stage are critical.
+*   **Targeted Peak-to-Gap Mass Migration:** Beyond simple gradients, "Peak-to-Gap" heuristics (**Gen 94**, **Gen 96**) redistribute mass from indices causing convolution peaks to "gaps" (indices with low convolution values). This approach, combined with **Gen 72's** "Peak Pressure" multiplicative scaling, effectively flattens the $L_\infty$ norm of the convolution.
+*   **Diverse Structural Seeding:** Initializing with theoretical models like symmetric power-laws ($(n-i)^{-p}$) or Gaussian hills provides a superior starting point compared to random noise. **Gen 90 (1.63)** and **Gen 96 (1.61)** specifically credited diverse power-law seeds for their convergence. **Gen 72** uses a 6-mode seeding strategy (including sine waves and sparse seeds) to ensure exploration of multiple basins.
+
+## Ineffective Approaches
+
+*   **Scoped Import Failures:** A persistent and critical failure mode identified in **Gens 91, 92, and 98** is the omission of `import numpy` or `import time` within the search function's scope. Despite potentially sophisticated logic (like "Projected Gradient Descent" in **Gen 92**), these programs received a score of 0.0 because they failed validation tests immediately.
+*   **Numerical Instability in High-Beta Gradients:** **Gen 99** failed validation likely due to numerical instability in "high-beta exponential gradient sharpening." Without the Log-Sum-Exp trick or proper normalization (like **Gen 72's** `_normalize_scale`), high $\beta$ values can cause overflow or produce sequences with `NaN` values, leading to an infinite evaluation value.
+*   **Late-Stage Symmetry Inconsistency:** While symmetry is known to be optimal, enforcing it too late or too strictly can trap the search. **Gen 97** likely failed to reach a competitive score (0.0/Validation fail) due to a failure to balance symmetry enforcement with the local perturbations needed to escape local minima at $n=768$.
+
+## Implementation Insights
+
+*   **Scale-Invariant Normalization:** The **Current Best (Gen 72)** employs a `_normalize_scale` function that forces $\sum A_i = n$. This simplifies the objective $2n \cdot \max(C) / (\sum A)^2$ to $2 \cdot \max(C) / n$, effectively transforming a complex ratio optimization into a peak-minimization task. This stabilization is a major factor in its 1.60 performance.
+*   **Multiplicative vs. Additive Mutations:** High-performing programs (**Gen 72, 93, 94**) favor multiplicative scaling (e.g., `seq[idx] *= (1.0 - sigma)`) for peak reduction. This is more stable for maintaining the non-negativity constraint and prevents the "zig-zag" instability often caused by additive Gaussian noise in sensitive regions.
+*   **Spectral Regularization (FFT Damping):** **Gen 72** and **Gen 95** use FFT-based mutations to damp high-frequency components (e.g., damping the top 80% of frequencies). This smoothing prevents the sequence from becoming "spiky," which naturally reduces the magnitude of the autocorrelation peaks.
+*   **Mutation Diversity and Weighting:** **Gen 72** uses a highly specialized suite of seven mutation types. The weighting (e.g., 35% chance for Sharpened Softmax, 20% for Peak Pressure) ensures that the most effective "surgical" moves are prioritized over "blind" block or scattered perturbations.
+
+## Performance Analysis
+
+*   **The 1.60 Convergence Barrier:** Performance has plateaued around the 1.60-1.62 range (**Gen 72: 1.60**, **Gen 94: 1.61**, **Gen 96: 1.61**, **Gen 90: 1.63**). This suggests that while the multi-resolution gradient-proxy approach is highly effective, it may be reaching the limits of local refinement.
+*   **Comparison of Gradient Proxies:** **Gen 94 (1.61)** used "hardmax" gradients, while **Gen 93 (1.71)** used "peak-dampening" proxies. The 0.10 score difference highlights that the specific sharpening of the gradient (controlled by $\beta$ or the "super-sharpened" logic in **Gen 96**) is the primary driver of refinement efficiency.
+*   **Time Allocation Impact:** The 0.0 scores of **Gens 91, 92, 98, and 99** highlight that algorithmic complexity is secondary to execution stability. Even "sophisticated" methods like Mass Transfer and Projected Gradient Descent are useless if they cannot complete within the time budget or lack essential imports. **Gen 72's** use of `budget_s * 0.96` as a hard deadline ensures it returns a valid result even under tight constraints.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Coupled "Peak-to-Gap" Mass Migration**: Instead of performing independent "Peak Pressure" (reduction) and "Efficiency Boost" (addition) moves, combine them into a single atomic operation. Identify indices contributing to the convolution maximum ($C_{max}$) and those contributing to the convolution minimum ($C_{min}$), then subtract mass from the former and add it to the latter. This "water-filling" approach directly flattens the $L_\infty$ norm of the convolution while keeping the sequence sum constant, providing more stable convergence than stochastic independent moves.
+
+2. **Push Softmax $\beta$ to "Hard-Max" Limits (500+) with Log-Stability**: To break the 1.60 plateau, the algorithm must isolate the exact sequence indices responsible for the peak convolution values. Increase the maximum $\beta$ to 500 or higher during the final $n=768$ stage, but ensure numerical stability using the identity $w = \exp(\beta \cdot (C / \max(C) - 1.0))$. This prevents the `NaN` or `Inf` values that caused failures in Gen 99 while allowing for the "surgical" precision needed to damp specific peaks.
+
+3. **Enforce Deterministic Symmetry Hardening in the Final Phase**: While maintaining some asymmetry is useful for navigating local optima early on, the optimal sequences for this task are theoretically symmetric. Shift from a probabilistic symmetry check to a deterministic constraint (`seq = (seq + seq[::-1]) / 2.0`) once progress exceeds 85% of the time budget. This effectively halves the search dimensionality at the moment of highest resolution, allowing the search to focus all remaining iterations on refining the symmetric envelope.
+
+4. **Transition from Exploratory to Surgical Mutation Weights**: Replace the current static mutation probabilities with a schedule that adapts based on the search progress and resolution. Allocate high weights (e.g., 60%) to "Spectral Mutation" and "Block Perturbation" during the $n=128$ and $n=256$ stages to define the global shape, then transition to over 85% combined weight for "Sharpened Softmax" and "Peak-to-Gap" moves during the final $n=768$ stage for high-precision exploitation.
+
+5. **Frequency-Selective Spectral Damping via Power-Law Fitting**: Refine the spectral mutation to target frequencies that deviate from the "ideal" power-law decay ($k^{-p}$) identified in successful seeds like Gen 90 and 96. Instead of a blanket 80% damping of high frequencies, calculate the sequence's current power spectrum and specifically damp bands that show excess energy relative to the $k^{-0.5}$ envelope. This preserves the beneficial global structure while suppressing the high-frequency "jitter" often introduced by stochastic gradient-proxy moves.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Annealed High-Beta Softmax Gradient Weighting:** The current best program (**Gen 72, Score 1.60**) and high-performing successors like **Gen 109 (1.61)** and **Gen 108 (1.62)** utilize a softmax-weighted gradient. By applying a high and increasing $\beta$ (e.g., $\beta$ scaling from 30 to 200), the algorithm performs "surgical" dampening of the convolution peaks. This involves calculating which specific indices $A_i$ contribute most to the maximum value of the convolution $C = A * A$ and targeting those for reduction.
+*   **Multi-Resolution Resolution Ladders with Time-Budgeting:** Consistency in reaching scores near 1.60 is driven by a resolution-climbing strategy (e.g., $128 \to 256 \to 512 \to 768$). **Gen 72** and **Gen 109** allocate specific time shares to these scales, ensuring the global "envelope" of the sequence is optimized at low resolution before performing high-frequency refinement at $n=768$. Programs that failed to manage this transition effectively, or used simpler resolution schedules, typically scored higher (e.g., **Gen 101** at 1.71).
+*   **Peak-to-Gap Mass Migration:** A highly effective heuristic used in **Gen 103 (1.70)**, **Gen 105 (1.62)**, and **Gen 109 (1.61)** is the "Peak-to-Gap" transfer. Instead of simply reducing mass at peak-contributing indices, this move redistributes that mass to "gaps" (indices where the convolution value is low). This maintains the sequence sum while simultaneously flattening the $L_\infty$ norm of the convolution.
+*   **Diverse Theoretical Seeding:** High-performing programs (**Gen 72, Gen 100, Gen 105, Gen 109**) move beyond random initialization. They utilize symmetric power-law seeds ($(n-i)^{-p}$), Gaussian hills, and sine waves. **Gen 100** and **Gen 105** (both 1.62) specifically credited power-law seeding for providing a robust starting point that the surgical gradient could then refine into a high-resolution optimum.
+
+## Ineffective Approaches
+
+*   **Missing Scope for Standard Imports:** A persistent failure mode seen in **Gen 102 (0.0)** is the omission of essential library imports like `numpy` and `time` within the search function. Even mathematically sophisticated strategies such as "exponentiated gradient methods" fail immediately if the runtime environment is not properly initialized.
+*   **Numerical Instability in Gradient Proxies:** Several programs using advanced numerical techniques, such as **Gen 106 (0.0)** with "log-stable gradient optimization," failed validation. This is often due to the lack of numerical guards (like the Log-Sum-Exp trick or small epsilon constants) when calculating high-beta softmaxes, leading to `NaN` values or infinite loops.
+*   **Unrefined Gradient Moves:** **Gen 101 (1.71)** achieved a significantly worse score than the best programs despite using a "Relative-Gradient" move. The feedback suggests that generic gradient moves are less effective than the "super-sharpened" or "surgical" moves that specifically isolate the highest-contributing elements of the convolution peaks.
+
+## Implementation Insights
+
+*   **Scale-Invariant Objective Stabilization:** The **Current Best (Gen 72)** uses a `_normalize_scale` function that forces $\sum A_i = n$. This simplifies the objective $2n \cdot \max(C) / (\sum A)^2$ to $2 \cdot \max(C) / n$. This transformation turns a complex ratio into a straightforward peak-minimization task, preventing the search from chasing trivial scaling solutions.
+*   **Spectral Regularization (FFT Damping):** **Gen 72, Gen 103,** and **Gen 107** employ FFT-based mutations to damp high-frequency components. By specifically damping the top 80% of frequencies, the search prevents the sequence from becoming "spiky." Smooth sequences naturally yield lower convolution maxima for a given sum.
+*   **Multiplicative Mutation Dynamics:** Top programs (**Gen 72, 107, 109**) favor multiplicative scaling (e.g., `seq[idx] *= (1.0 - sigma)`) over additive noise. Multiplicative moves naturally respect the non-negativity constraint and allow for more granular control when "shaving" the tops of peaks compared to "blind" additive Gaussian perturbations.
+*   **Symmetry Hardening:** While the optimal sequence is expected to be symmetric, high-performers like **Gen 72** and **Gen 108** balance this by enforcing symmetry periodically (e.g., 40-80% of the time) rather than as a strict constraint. This "hardening" allows the search to explore asymmetric paths that might bypass local minima before forcing the final optimal symmetric shape.
+
+## Performance Analysis
+
+*   **Convergence at 1.60-1.62:** The evaluation results show a strong convergence plateau. **Gen 72** holds the lead at 1.60, with **Gen 109 (1.61)**, **Gen 100 (1.62)**, **Gen 105 (1.62)**, and **Gen 108 (1.62)** following closely. This suggests the combination of power-law seeding and surgical gradient refinement is approaching the theoretical limit for this search space.
+*   **Sensitivity Analysis vs. Random Search:** The performance gap between **Gen 108 (1.62)** and more stochastic approaches highlights the value of sensitivity-driven local search. Programs that identify and reduce specific indices contributing to convolution peaks consistently outperform those relying on block or scattered perturbations.
+*   **Impact of Multi-Resolution Efficiency:** Programs like **Gen 101 (1.71)** that use multi-resolution but lack the refined "surgical" mutation suite of **Gen 72** show that resolution scaling is a necessary but not sufficient condition for top-tier performance. The quality of the mutation operator at the highest resolution ($n=768$) is the primary differentiator between a 1.7x score and a 1.6x score.
+*   **Robustness vs. Complexity:** **Gen 104** and **Gen 106** both received scores of 0.0 despite implementing "mass-transfer" and "log-gradient" strategies. This indicates that as algorithmic complexity increases, the risk of failing validation (due to sequence length errors or objective mismatches) increases, making robust normalization and bounds-checking (as seen in **Gen 72**) critical.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Atomic Peak-to-Gap Mass Migration**: Instead of performing independent "Sharpened Softmax" (reduction) and "Efficiency Boost" (addition) moves, combine them into a single atomic operation. In one step, identify the indices with the highest contribution to the convolution maximum using the high-beta gradient and subtract mass, then simultaneously add that exact amount of mass to indices identified by the inverse gradient (convolution minima). This "water-filling" approach maintains the sequence sum internally, leading to more stable convergence and less reliance on the global normalization function.
+
+2. **Push Softmax $\beta$ to "Ultra-Sharp" Limits (500+) with Log-Stability**: To break the 1.60 plateau, the algorithm must isolate the exact sequence indices responsible for the peak convolution values. Increase the maximum $\beta$ from 200 to 500 or higher during the final $n=768$ stage, ensuring numerical stability using the identity $w = \exp(\beta \cdot (C / \max(C) - 1.0))$. This creates a "Dirac-like" selection mask that allows for the surgical precision needed to shave off the final fractions of the convolution $L_\infty$ norm.
+
+3. **Transition to Deterministic Symmetry Hardening in the Final Phase**: While maintaining asymmetry is useful for navigating local optima at low resolutions, the optimal sequence is theoretically symmetric. Shift from the current probabilistic symmetry check to a deterministic constraint (`seq = (seq + seq[::-1]) / 2.0`) once the search enters the final 15% of the time budget or the highest resolution ($n=768$). This effectively halves the search dimensionality at the moment of highest computational cost, allowing the search to focus all remaining iterations on refining the symmetric envelope.
+
+4. **Replace Fixed Time-Shares with Plateau-Triggered Upscaling**: Instead of using hardcoded time shares (e.g., 0.10, 0.25, 0.50), implement a "patience" mechanism where the resolution only increases after the current scale has failed to produce an improvement for a set number of iterations. This ensures that the global "envelope" of the sequence is fully optimized at lower resolutions (128 and 256) before committing the remaining time to high-frequency refinement at $n=768$, preventing the search from carrying sub-optimal global shapes into the expensive final stage.
+
+5. **Frequency-Selective Spectral Smoothing via $1/f^\alpha$ Envelope Fitting**: Refine the spectral mutation by calculating the current sequence's power spectrum and damping frequencies that deviate significantly from an "ideal" $1/f^\alpha$ decay (where $\alpha \approx 0.5$). Instead of a blanket 40% damping of high frequencies, this approach preserves the beneficial global structure while specifically suppressing the high-frequency "jitter" or "spikiness" often introduced by stochastic gradient-proxy moves at high resolution.

+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+Based on the evaluation of programs from Generations 110 through 119 and the historical performance of the current best program (Generation 72), the following optimization insights have been extracted.
+
+## Successful Algorithmic Patterns
+
+*   **Surgical Peak-to-Gap Mass Migration:** The most effective refinement across recent generations (Gen 110, 112, 114, 118) is the "Mass Migration" heuristic. Instead of merely dampening values that contribute to convolution peaks, this approach identifies "valleys" or "gaps" in the convolution output and shifts "atomic mass" from the peak-contributing sequence indices to those that fill the gaps. **Gen 112 (Score 1.62)** and **Gen 118 (Score 1.62)** demonstrate that this preserves the sequence sum while directly flattening the $L_\infty$ norm.
+*   **Log-Gradient and High-Beta Softmax Weighting:** The **current best program (Gen 72, Score 1.60)** and its high-performing successors like **Gen 117 (Score 1.61)** utilize a "surgical" gradient update. By applying a high softmax $\beta$ (scaling from 30 up to 200), the algorithm isolates the exact sequence indices responsible for the maximum convolution value. **Gen 110 (Score 1.62)** specifically uses a "Log-Gradient" update to provide more stable descent on the non-convex $L_\infty$ objective.
+*   **Progressive Multi-Resolution Resolution Ladders:** Consistent performance is tied to a hierarchical scaling strategy (starting at $n=128$ and interpolating up to $n=768$). **Gen 72** and **Gen 119 (Score 1.63)** allocate specific time-shares to each resolution. This allows the search to find a smooth global "envelope" at low resolutions before performing high-frequency "surgical" refinement at $n=768$.
+*   **Power-Law Seeding as a Baseline:** High-performing programs (**Gen 112, Gen 116, Gen 72**) use theoretical priors for initialization. **Gen 116 (Score 1.65)** and **Gen 112 (Score 1.62)** specifically utilize power-law seeds ($n^{-0.5}$) and symmetric power-law shapes. These seeds provide a much lower starting objective value (approaching ~1.57 for large $n$) compared to random initialization, which the gradient search then refines.
+
+## Ineffective Approaches
+
+*   **Constraint and Dimensionality Mismatches:** Programs like **Gen 111 (Score 0.0)** and **Gen 115 (Score 0.0)** failed validation despite complex strategies. **Gen 111** failed all validation tests, likely due to returning a sequence of incorrect length (768) during intermediate resolution checks or failing to meet non-negativity constraints within its "frequency-domain jittering."
+*   **Unstable Gradient Proxies:** **Gen 115** attempted a "surgical sensitivity gradient" but failed to reach the performance threshold. This suggests that complex gradient approximations (like soft-max weighted gradients) require precise numerical guarding (e.g., epsilon constants, Log-Sum-Exp) and robust normalization to avoid stagnation or numerical explosion.
+*   **Rigid Symmetry Enforcement:** While the optimal sequence is likely symmetric, programs that enforce symmetry too early or too strictly often get trapped in local minima. The **current best (Gen 72)** uses "Symmetry Hardening," enforcing it only 40-80% of the time, allowing the search to explore asymmetric paths that might bypass barriers before converging on a symmetric final shape.
+
+## Implementation Insights
+
+*   **Scale-Invariant Normalization:** The **current best (Gen 72)** uses a `_normalize_scale` function that forces $\sum A_i = n$. This simplifies the objective $2n \cdot \max(C) / (\sum A)^2$ to $2 \cdot \max(C) / n$, effectively transforming a ratio-optimization problem into a straightforward peak-minimization task.
+*   **Multiplicative Mutation Dynamics:** Top programs (**Gen 72, Gen 117, Gen 119**) favor multiplicative scaling (e.g., `seq[idx] *= (1.0 - sigma)`) over additive noise. Multiplicative moves naturally respect the non-negativity constraint and allow for "shaving" the peaks of the sequence with much higher precision than additive Gaussian moves.
+*   **Spectral Regularization (FFT Damping):** **Gen 72** and **Gen 117** use FFT-based mutations to damp high-frequency components. By damping the top 80% of frequencies, the search maintains a "smooth" sequence, which inherently produces lower convolution maxima than "spiky" or "noisy" sequences.
+*   **Mirror Descent and Peak Pressure:** **Gen 119** and **Gen 117** implemented "Peak Pressure" moves. This involves calculating which pairs $(i, j)$ contribute to the convolution peak at index $k$ (where $k = i+j$) and specifically reducing the product $A_i A_j$.
+
+## Performance Analysis
+
+*   **Convergence Plateau at 1.60-1.62:** There is a clear performance density between 1.60 and 1.62. **Gen 72** holds the record at **1.60**, followed closely by **Gen 117 (1.61)** and a cluster of programs at **1.62 (Gen 110, 112, 118)**. This suggests that combining power-law seeding with surgical gradient refinement is the most robust path toward the theoretical optimum.
+*   **Superiority of Targeted Search over Stochastic Search:** The failure of **Gen 115** and the mediocre performance of generic multi-resolution searches (e.g., Gen 101 in previous rounds) emphasize that the "surgical" nature of the mutation is the differentiator. Programs that identify specific indices responsible for the convolution maximum consistently outperform those relying on scattered or block perturbations.
+*   **Resolution Climbing Efficiency:** The score of **1.61 (Gen 117)** demonstrates that the transition from 512 to 768 is the most critical phase. Programs that spend at least 50% of their time budget at the final resolution (as seen in the `time_shares` logic of **Gen 72**) achieve significantly lower values than those that divide time equally or spend too much time on low-resolution exploration.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Atomic Peak-to-Gap Mass Migration**: Replace independent "Sharpened Softmax" and "Efficiency Boost" moves with a single atomic operation that identifies indices contributing to convolution maxima (using high-beta softmax) and convolution minima simultaneously. Shift "mass" directly from peak-contributing indices to valley-contributing indices to maintain the sequence sum internally, which provides more stable convergence than relying on global normalization after separate additive/multiplicative moves.
+
+2. **Push Softmax $\beta$ to "Ultra-Sharp" Limits (500+) with Log-Stability**: To break the 1.60 plateau, the algorithm must isolate the exact sequence indices responsible for the peak convolution values with higher precision. Increase the maximum $\beta$ from 200 to 500 or higher during the final $n=768$ stage, ensuring numerical stability by using the log-space identity $w = \exp(\beta \cdot (C / \max(C) - 1.0))$, effectively creating a "Dirac-like" selection mask for surgical peak reduction.
+
+3. **Transition to Deterministic Symmetry Hardening in the Final Phase**: While maintaining asymmetry helps navigate local optima at low resolutions, the optimal sequence is theoretically symmetric. Shift from probabilistic symmetry checks to a deterministic constraint (`seq = (seq + seq[::-1]) / 2.0`) once the search enters the final 15% of the time budget or the highest resolution ($n=768$), effectively halving the search dimensionality at the moment of highest computational cost.
+
+4. **Replace Fixed Time-Shares with Plateau-Triggered Upscaling**: Instead of hardcoded time shares (0.10, 0.25, 0.50), implement a "patience" mechanism where the resolution only increases after the current scale has failed to produce an improvement for a set number of iterations (e.g., 50-100). This ensures the global "envelope" is fully optimized at lower resolutions before committing the remaining time to high-frequency refinement at $n=768$, preventing the carry-over of sub-optimal global shapes.
+
+5. **Frequency-Selective Spectral Smoothing via Power-Law Envelope Fitting**: Refine the spectral mutation by calculating the sequence's power spectrum and specifically damping components that deviate significantly from a $1/f^{0.5}$ decay. Instead of a blanket 40% damping of high frequencies, this approach preserves the beneficial global structure found in high-performing power-law seeds while suppressing the high-frequency "jitter" introduced by stochastic gradient-proxy moves.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Multiplicative Log-Stable Mirror Descent:** Programs utilizing multiplicative updates instead of additive noise achieved high scores (**Gen 121: 1.62, Gen 124: 1.63, Gen 127: 1.62**). This approach, similar to Mirror Descent, naturally respects the non-negativity constraint and allows for fine-grained suppression of convolution peaks without destroying the sequence's global structure.
+*   **Surgical Peak-to-Gap Mass Migration:** Building on previous successes, **Gen 123 (Score 1.62)** and **Gen 122 (Score 1.64)** effectively used heuristics to identify sequence indices contributing to convolution maxima and redistributed their "mass" to "gaps" or "valleys" in the convolution output. This technique preserves the sequence sum $\sum A_i$ while directly flattening the $L_\infty$ norm of the convolution.
+*   **High-Beta Softmax Gradient Weighting:** The **current best program (Gen 72, Score 1.60)** and **Gen 127 (Score 1.62)** use a very high softmax $\beta$ (scaling from 30 up to 200) to create a "sensitivity gradient." This isolates the exact sequence indices responsible for the maximum convolution value, allowing for "surgical" reductions that are more effective than broader stochastic perturbations.
+*   **Progressive Resolution Laddering with Specific Time-Shares:** Consistency in reaching the 1.60-1.64 range is tied to scaling from low resolutions (N=128) to high (N=768). **Gen 72 (Score 1.60)** demonstrates that spending a disproportionate amount of the time budget (50%+) on the final resolution (768) is critical for fine-tuning the sequence envelope.
+
+## Ineffective Approaches
+
+*   **Code Environment Omissions:** Several theoretically sound programs (**Gen 120, 125, 129**) failed entirely (Score 0.0) due to missing `import numpy` or `import time` statements within the provided code blocks. This recurring implementation error highlights that even sophisticated strategies like "Natural Gradients" or "Log-Gradient Sequence Optimization" cannot be evaluated if basic dependencies are missing.
+*   **Numerical Instability in Complex Mutations:** Programs like **Gen 128 (Score 0.0)** and **Gen 126 (Score 0.0)** failed despite using sophisticated "Surgical Atomic Migration" and "Convolutional Mass Migration." Feedback suggests that these complex logic paths frequently suffer from numerical instabilities (NaN/Inf) or logic errors in objective scaling, emphasizing the need for robust normalization and safety clips like those found in **Gen 72**.
+*   **Over-reliance on Spectral Smoothing:** While FFT-based mutations are helpful for maintaining a smooth envelope (**Gen 121, Gen 72**), programs that prioritize spectral smoothing over targeted gradient-based peak reduction often fail to break the 1.65 barrier, as seen in the slightly lower performance of **Gen 122 (Score 1.64)**.
+
+## Implementation Insights
+
+*   **Scale-Invariant Objective Simplification:** The **current best program (Gen 72)** uses a `_normalize_scale` function to force $\sum A_i = n$. This transforms the complex ratio $2n \cdot \max(C) / (\sum A)^2$ into a simpler peak-minimization task: $2 \cdot \max(C) / n$. This simplification prevents the optimizer from "cheating" by merely scaling values and focuses the search on the sequence's shape.
+*   **Strategic Symmetry Hardening:** **Gen 72** and **Gen 127** do not enforce symmetry 100% of the time. Instead, they use "Symmetry Hardening," where symmetry is enforced more strictly (e.g., 80% of the time) only in the later stages of the run or after a significant percentage of the time budget has elapsed. This allows for early-stage exploration of asymmetric shapes that might bypass local minima.
+*   **Multiplicative "Peak Pressure" Moves:** High-performing programs (**Gen 72, Gen 123, Gen 127**) calculate which pairs $(i, j)$ contribute to the maximum convolution value at index $k$ (where $k = i+j$) and apply multiplicative scaling (e.g., `seq[idx] *= (1.0 - sigma)`) to those specific indices. This "shaving" of the sequence is more precise than additive Gaussian noise.
+
+## Performance Analysis
+
+*   **The 1.60 Performance Barrier:** The **current best program (Gen 72)** maintains the top score of **1.60**. A significant cluster of programs in the most recent generation (**Gen 121, 123, 127**) achieved a score of **1.62**. This suggests a convergence plateau where standard log-gradient and mirror descent techniques consistently reach 1.62, but require the specific high-beta tuning and time-allocation strategy of Gen 72 to reach 1.60.
+*   **Correlation Between Multi-Resolution and Success:** Every program that passed validation (Gens 121, 122, 123, 124, 127) utilized a multi-resolution strategy starting at N=128 and upscaling to N=768. Programs that attempted to search at N=768 directly or with insufficient laddering generally failed to achieve competitive scores.
+*   **Impact of Power-Law Seeding:** Programs that incorporated power-law initializations ($n^{-0.5}$) or symmetric power-law shapes (**Gen 122, Gen 72**) started the optimization process much closer to the target values than those using random or uniform seeds. This initial advantage is critical given the 10-second time budget.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Atomic Peak-to-Valley Mass Migration**: Instead of treating "Peak Pressure" (shaving peaks) and "Efficiency Boost" (raising valleys) as independent operations, implement a combined move that identifies indices contributing to convolution maxima and minima simultaneously. By subtracting a small multiplicative amount from peak-contributing indices and redistributing that exact mass to indices that contribute to the convolution's "valleys," you maintain the sequence sum $\sum A_i$ internally. This provides more stable convergence than relying on global normalization after separate moves and directly flattens the $L_\infty$ norm.
+
+2. **Push Softmax $\beta$ to "Ultra-Sharp" Limits (500+)**: To break the 1.60 plateau, increase the maximum softmax $\beta$ from 200 to 500 or higher during the final $n=768$ resolution stage. Use the numerically stable log-space identity $w = \exp(\beta \cdot (C / \max(C) - 1.0))$ to create a near-mask for the exact sequence indices responsible for the peak. This allows for "nanosurgery" on the sequence, suppressing the specific indices causing the $L_\infty$ bottleneck without affecting the global power-law envelope.
+
+3. **Transition to Deterministic Symmetry in the Final Phase**: While the current program uses probabilistic symmetry, the theoretical optima for this problem are symmetric. Shift from 80% probabilistic symmetry to a 100% deterministic constraint (`seq = (seq + seq[::-1]) / 2.0`) once the search enters the final resolution ($n=768$) or the last 15% of the time budget. This effectively halves the search dimensionality at the most computationally expensive stage, allowing for more iterations per second when refining high-frequency details.
+
+4. **Replace Fixed Time-Shares with Plateau-Triggered Upscaling**: Rather than using hardcoded time shares (10%, 25%, 50%), implement a "patience" mechanism where the resolution only increases after the current scale has failed to produce a significant improvement for a set number of iterations (e.g., 100). This ensures the global "envelope" is fully optimized at lower resolutions (where iterations are cheap) before committing the remaining time to fine-tuning at $n=768$, preventing the algorithm from carrying over sub-optimal global shapes into the final stage.
+
+5. **Formalize Multiplicative Updates as Mirror Descent Steps**: Replace the current heuristic multiplicative moves (`seq *= (1.0 - sigma)`) with a formal Mirror Descent step using a Log-barrier or Entropic projection. Update the sequence using $A_{new} = A \cdot \exp(-\eta \cdot \nabla_{conv})$, where $\nabla_{conv}$ is the gradient of the max-convolution objective. This approach naturally respects the non-negativity constraint and has been shown in Gens 121-127 to be more effective than additive Gaussian noise for preserving the delicate power-law structure of high-performing sequences.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+Based on the evaluation results of the recent generations and the performance of the current best program (Gen 72), here is the updated analysis of the AC inequality task.
+
+## Successful Algorithmic Patterns
+
+*   **Surgical Peak Pressure Moves (Multiplicative Scaling):** The most effective programs (**Gen 72: 1.60**, **Gen 139: 1.62**, **Gen 132: 1.62**) do not rely solely on additive noise or generic gradients. They calculate the specific pairs of indices $(i, j)$ that contribute to the convolution maximum ($k = i + j$) and apply multiplicative reductions (e.g., `seq[idx] *= (1.0 - sigma)`) to those indices. This "shaving" technique directly suppresses the $L_\infty$ norm of the convolution.
+*   **High-Beta Softmax Gradient Weighting:** Programs that achieve scores near or at the 1.60 mark (**Gen 72**, **Gen 138**, **Gen 134**) use an extremely high softmax $\beta$ (scaling from 30 up to 200) to approximate the gradient of the maximum. This creates a "sensitivity gradient" that isolates the sequence elements responsible for the current convolution peak, allowing for precision updates rather than global smoothing.
+*   **Multi-Resolution Resolution Laddering:** Every successful program (**Gen 72**, **Gen 132**, **Gen 136**, **Gen 139**) follows a strict resolution ladder (e.g., 128 → 256 → 512 → 768). This allows the optimizer to solve the global shape of the sequence (the "envelope") at lower dimensions before performing high-precision surgery at the final 768-length resolution.
+*   **Diverse Power-Law Seeding:** Initializing the search with symmetric and asymmetric power laws ($x^{-0.5}$) remains a critical success factor. **Gen 139 (1.62)** and **Gen 132 (1.62)** explicitly utilize modes for symmetric power laws and Gaussian hills, which start the optimization much closer to the theoretical bound than random initialization.
+
+## Ineffective Approaches
+
+*   **Generic Mirror Descent without Heuristics:** Programs like **Gen 134** and **Gen 138** implemented sophisticated "Entropic Mirror Descent" but only achieved a best value of **2.00**. While mathematically sound, these methods without task-specific "peak surgery" often fail to break the baseline value (which is 2.0 for a flat sequence), indicating that the objective's non-differentiability requires more aggressive heuristics.
+*   **Missing Imports and Environment Omissions:** Despite sophisticated theoretical descriptions, **Gen 130**, **Gen 131**, and **Gen 135** all failed with a **0.0 score**. These failures often stem from basic implementation errors (missing `import` statements or incorrect variable names) within the evolution blocks, demonstrating that complexity must not come at the cost of execution robustness.
+*   **Asymmetric "Mass Migration" in Final Stages:** While **Gen 135** attempted "peak-to-valley mass migration," its failure suggests that moving mass in an asymmetric fashion at high resolutions without strict symmetry preservation can violate the optimal structure of the AC inequality, which tends toward symmetric sequences.
+
+## Implementation Insights
+
+*   **Scale-Invariant Objective Simplification:** The **current best program (Gen 72)** and **Gen 139** use a `_normalize_scale` function to fix $\sum A_i = n$. This simplifies the objective from $2n \cdot \max(C) / (\sum A)^2$ to a simpler $2 \cdot \max(C) / n$. This prevents the optimizer from wandering into scale-related local minima and focuses it entirely on the shape of the sequence.
+*   **Strategic Symmetry Hardening:** **Gen 72** uses a probabilistic symmetry approach: it enforces symmetry only 40% of the time during early exploration but increases this to 100% (or uses strictly symmetric perturbations) in the final 25% of the time budget. This allows the search to bypass local minima through asymmetric shapes before "hardening" into the required symmetric form.
+*   **Spectral Filter Damping:** **Gen 139** and **Gen 72** apply FFT-based spectral mutations but purposefully dampen high-frequency components (`f[int(len(f)*0.2):] *= (1.0 - 0.4 * sigma)`). This maintains a smooth sequence envelope, which is a known characteristic of low-convolution sequences.
+
+## Performance Analysis
+
+*   **The 1.60 "Best" Plateau:** **Gen 72** remains the top performer with a score of **1.60**. A significant cluster of programs (**Gen 132, 136, 139**) has converged on the **1.62 - 1.63** range. The difference appears to be the aggressive "Peak Pressure" move in Gen 72, which specifically targets contributing pairs rather than just using the softmax gradient.
+*   **Failure of Complex Optimizers:** There is a notable trend where more "mathematically complete" optimizers (like those in **Gen 134** and **Gen 138**) are being outperformed by "heuristic-heavy" gradient descent (**Gen 72, Gen 139**). This suggests that for this specific 10-second time budget, a hybrid of local search and targeted "shaving" is superior to formal entropic updates.
+*   **Impact of Time Allocation:** Successful programs consistently allocate the majority of the time budget (50%+) to the final sequence length (768). Programs that distribute time equally across all resolutions often fail to reach the 1.62 mark because they lack the refinement iterations needed to flatten the final convolution spikes.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Unified Peak-to-Valley Mass Migration**: Instead of independent "Peak Pressure" (shaving) and "Efficiency Boost" (raising) moves, implement a combined move that identifies indices $(i, j)$ contributing to the convolution maximum and indices contributing to the minimum. Subtract a small multiplicative amount from peak-contributing indices and redistribute that exact mass to the valley-contributing indices; this preserves the sequence sum $\sum A_i$ internally and directly flattens the $L_\infty$ norm more efficiently than global normalization.
+
+2. **Push Softmax $\beta$ to "Nanosurgery" Limits (500-1000)**: To break the 1.60 plateau, significantly increase the softmax $\beta$ from the current max of 200 to 500 or higher during the final $n=768$ resolution stage. Use the numerically stable identity $w = \exp(\beta \cdot (C / \max(C) - 1.0))$ to create an ultra-sharp mask that isolates only the exact sequence elements responsible for the current convolution spike, allowing for surgical reductions that don't degrade the rest of the sequence's "envelope."
+
+3. **Enforce Deterministic Half-Length Optimization in the Final Phase**: Since theoretical optima are symmetric, once the search reaches the final resolution ($n=768$) or the last 20% of the time budget, switch to a mode that only mutates the first $n/2$ elements and mirrors them to the second half (`seq[n//2:] = seq[:n//2][::-1]`). This effectively halves the search dimensionality at the most computationally expensive stage, doubling the number of refinement iterations possible within the remaining time budget.
+
+4. **Replace Fixed Time-Shares with Plateau-Triggered Upscaling**: Rather than using hardcoded time shares (10%, 25%, 50%), implement a "patience" mechanism where the resolution only increases after the current scale has failed to produce a significant improvement for a set number of iterations (e.g., 100-200). This ensures the global "envelope" is fully optimized at lower resolutions where iterations are computationally cheap before committing the remaining time to high-precision fine-tuning at $n=768$.
+
+5. **Apply Envelope-Preserving Spectral Smoothing**: Periodically apply a low-pass filter via FFT to the best sequence to re-impose a smooth power-law envelope, as aggressive "peak surgery" can introduce high-frequency "jitter" that creates new, smaller spikes. By slightly dampening high-frequency components (e.g., `f[int(len(f)*0.1):] *= 0.95`) every few successful moves, you ensure the sequence maintains the smooth, low-convolution shape characteristic of the best-performing $x^{-0.5}$ power-law structures.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Surgical Peak Pressure Moves (Targeted Multiplicative Scaling):** The top-performing program (**Gen 72**, score -1.60) distinguishes itself from the 1.61–1.62 cohort (**Gens 141, 145, 146, 148**) by using a specific "Peak Pressure" mutation. This move identifies the exact pairs of indices $(i, j)$ such that $i + j$ equals the index of the convolution maximum and applies multiplicative reductions to those specific elements. This is more precise than the broader "softmax gradients" used by others.
+*   **High-Beta Softmax Gradient Weighting:** Programs achieving values between 1.60 and 1.61 (**Gen 72, Gen 141, Gen 148**) utilize an extremely high softmax $\beta$ (often scaling from 30 up to 200). This concentrates the "gradient" on the absolute highest peaks of the convolution, allowing the optimizer to perform "nanosurgery" on the sequence elements most responsible for the current $L_\infty$ norm.
+*   **Multi-Resolution Resolution Laddering:** Every successful recent program (**Gens 140, 141, 144, 145, 146, 148**) follows a strict resolution ladder (128 → 256 → 512 → 768). This strategy allows the algorithm to establish the global "envelope" of the sequence at low resolutions before dedicating the final 50% of the time budget to fine-tuning the 768-element sequence.
+*   **Diverse Theoretical Seeding:** Initializing with symmetric power-law shapes ($x^{-0.5}$) remains a cornerstone of success. Programs like **Gen 145 (1.61)** and **Gen 146 (1.62)** explicitly prioritize symmetric power-law and Gaussian hill seeds, which start the optimization significantly closer to the theoretical 1.57 limit than random or uniform starts.
+
+## Ineffective Approaches
+
+*   **Logic Complexity vs. Execution Budget:** Programs like **Gen 149** (score 0.0) attempted "Symmetric Nanosurgery" with complex transitions and spectral dampening but failed to return a valid sequence. In a strict 10-second budget, overly complex mutation logic or multi-resolution transitions can prevent the optimizer from performing enough iterations to reach the competitive 1.61–1.62 range.
+*   **Missing Dependencies:** **Gen 143** and **Gen 142** failed (score 0.0) due to basic implementation errors, such as missing `import` statements for `numpy` or `time`. This highlights that even sophisticated "efficiency-gap" gradients are useless if the code is not self-contained.
+*   **Generic Convergence (Baseline Plateau):** **Gen 147** achieved a value of 2.00, which is the baseline value for a uniform sequence. Despite its description of "surgical peak-to-valley mass migration," its failure to break below 2.0 suggests that the "gradient" calculation was either incorrectly implemented or lacked the aggressive "shaving" intensity needed to move away from the uniform local minimum.
+
+## Implementation Insights
+
+*   **Scale-Invariant Normalization:** **Gen 72** and **Gen 146** utilize a `_normalize_scale` function to keep $\sum A_i = n$. By fixing the sum, the complex objective $2n \cdot \max(C) / (\sum A)^2$ simplifies to $2 \cdot \max(C) / n$, effectively removing a degree of freedom and preventing the optimizer from wandering into scale-related local minima.
+*   **Probabilistic Symmetry Hardening:** The current best program (**Gen 72**) employs a "Symmetry Hardening" strategy: it enforces symmetry only 40% of the time during early exploration but increases this to 100% (or uses strictly symmetric perturbations) in the final phase. This allows the search to explore asymmetric sequence space to bypass local minima before converging on the symmetric structures known to be optimal for the AC inequality.
+*   **Spectral High-Frequency Damping:** **Gen 72** and **Gen 146** apply FFT-based spectral mutations but specifically dampen high-frequency components (`f[int(len(f)*0.2):] *= (1.0 - 0.4 * sigma)`). This preserves the smoothness of the sequence, as the optimal coefficient sequences for this problem are known to have smooth, non-oscillatory envelopes.
+
+## Performance Analysis
+
+*   **The 1.60-1.62 Competitive Cluster:** There is a significant performance plateau between **1.60 (Gen 72)** and **1.62 (Gens 140, 146)**. The difference is largely attributed to the precision of the mutations: **Gen 72** uses index-pair-specific pressure moves, whereas the 1.62 programs rely more on general convolution gradients.
+*   **Impact of Time Allocation:** Successful programs (**Gen 141, 148**) allocate the largest share of time (usually 50% or more) to the final 768-resolution stage. Programs that distribute time too evenly across lower resolutions fail to perform the hundreds of "surgical" iterations required to flatten the final convolution spikes at the target length.
+*   **Consistency of Multi-resolution:** Programs that skipped resolutions or attempted to solve at 768 immediately consistently underperformed or failed to converge. The 128 → 256 → 512 → 768 progression has become the standard "backbone" for all programs reaching the 1.61 performance tier.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Unified Peak-to-Valley Mass Migration**: Instead of performing independent "Peak Pressure" (shaving) and "Efficiency Boost" (raising) moves, implement a combined move that identifies indices $(i, j)$ contributing to the convolution maximum and indices contributing to the minimum. Subtract a small multiplicative amount from peak-contributing indices and redistribute that exact mass to the valley-contributing indices; this preserves the sequence sum internally and flattens the $L_\infty$ norm more directly than global normalization.
+
+2. **Push Softmax $\beta$ to "Nanosurgery" Limits (500-1000)**: To break the 1.60 plateau, significantly increase the softmax $\beta$ from the current max of 200 to 500 or higher during the final $n=768$ resolution stage. Use the numerically stable identity $w = \exp(\beta \cdot (C / \max(C) - 1.0))$ to create an ultra-sharp mask that isolates only the exact sequence elements responsible for the current convolution spike, allowing for surgical reductions that don't degrade the rest of the sequence's smooth envelope.
+
+3. **Transition to Deterministic Half-Length Optimization in the Final Phase**: Since theoretical optima are symmetric, once the search reaches the final resolution ($n=768$) or the last 25% of the time budget, switch to a mode that only mutates the first $n/2$ elements and mirrors them to the second half (`seq[n//2:] = seq[:n//2][::-1]`). This effectively halves the search dimensionality at the most computationally expensive stage, doubling the number of refinement iterations possible within the remaining time budget.
+
+4. **Replace Fixed Time-Shares with Plateau-Triggered Upscaling**: Rather than using hardcoded time shares (10%, 25%, 50%), implement a "patience" mechanism where the resolution only increases after the current scale has failed to produce a significant improvement for a set number of iterations (e.g., 100-200). This ensures the global "envelope" is fully optimized at lower resolutions where iterations are computationally cheap before committing the maximum possible remaining time to high-precision fine-tuning at $n=768$.
+
+5. **Apply Gradient-Based Gaussian Smoothing**: After calculating the softmax gradient or peak pressure indices, apply a small Gaussian kernel to the "delta" or "mask" before applying it to the sequence. This prevents the "nanosurgery" from introducing high-frequency "jitter" or jagged edges, which often create new, secondary convolution spikes that prevent the $L_\infty$ norm from dropping below the 1.60 threshold.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Surgical Peak Pressure Moves (Targeted Multiplicative Scaling):** The top-performing algorithm (**Generation 72**, score 1.60) identifies the specific indices $i, j$ whose sum $i+j$ corresponds to the maximum convolution peak. It then applies multiplicative reductions specifically to those contributing elements. This "Peak Pressure Move" (used in 20% of mutations) is more precise than general gradient methods and allows the optimizer to "shave" the absolute maximum without disturbing the rest of the sequence.
+*   **High-Beta Softmax Gradient Weighting:** Programs achieving values between 1.60 and 1.61 (**Gen 72, Gen 155**) utilize an extremely high softmax $\beta$ (scaling from 30 up to 200 based on progress). This concentrates the gradient proxy on the absolute highest peaks of the convolution, enabling "nanosurgery" on the sequence elements most responsible for the current $L_\infty$ norm.
+*   **Symmetric Power-Law Seeding:** Initializing with symmetric power-law shapes ($x^{-p}$ where $p \approx 0.5$) remains the most effective starting point. **Gen 155 (1.61)** and **Gen 159 (1.62)** explicitly prioritize these seeds. This initialization places the search much closer to the theoretical lower bound (approximately 1.57) compared to random or uniform starts.
+*   **Multi-Resolution Laddering with Interpolation:** Every successful program (**Gens 150–159**, excluding failures) follows a strict resolution ladder (128 → 256 → 512 → 768). By using `np.interp` to upscale the sequence, the algorithm establishes the global "envelope" at low resolutions before dedicating the final 50% of the time budget to fine-tuning high-frequency details at $n=768$.
+
+## Ineffective Approaches
+
+*   **Premature Symmetry Constraint:** **Gen 153** (score 0.0) failed partly because it enforced symmetry too early in the optimization process. Feedback suggests that over-constraining the search space early prevents the algorithm from navigating around local minima. Successful programs like **Gen 72** only enforce symmetry 40% of the time initially, increasing to 100% only in the final stages.
+*   **Missing Dependencies and Basic Runtime Errors:** **Gen 153** failed to return a valid sequence due to missing `import numpy` and `import time` statements within the execution block. This follows a pattern seen in earlier generations (Gens 142, 143), where sophisticated mathematical logic is rendered useless by simple implementation oversights.
+*   **Low-Intensity Gradients:** **Gen 152** achieved a value of 2.00, which is the baseline for a flat/uniform sequence. Despite claiming to use "peak-to-valley mass migration," its failure to break the 2.00 barrier suggests the "gradient" steps were either too small or lacked the "shaving" intensity (high beta) required to push the sequence into a more optimal non-uniform shape.
+
+## Implementation Insights
+
+*   **Scale-Invariant Normalization:** The current best program (**Gen 72**) and several competitive variants (**Gen 158, Gen 159**) utilize a `_normalize_scale` function that enforces $\sum A_i = n$. By fixing the sum, the complex objective $2n \cdot \max(C) / (\sum A)^2$ is simplified to $2 \cdot \max(C) / n$, removing a degree of freedom and stabilizing the numerical optimization.
+*   **Efficiency Boost Mutations:** **Gen 72** includes an "Efficiency Boost" mutation (10% frequency) which identifies indices that contribute the *least* to convolution peaks and slightly increases their values. This provides a counter-balance to peak-shaving, ensuring the sequence sum remains stable while the profile flattens.
+*   **Spectral High-Frequency Damping:** Programs reaching the 1.60-1.62 range (**Gen 72, Gen 154, Gen 159**) apply FFT-based mutations but specifically dampen high-frequency components (`f[int(len(f)*0.2):] *= (1.0 - 0.4 * sigma)`). This preserves the smoothness of the sequence envelope, which is a known characteristic of optimal solutions for this inequality.
+
+## Performance Analysis
+
+*   **The 1.60-1.62 Competitive Cluster:** There is a significant performance plateau between **1.60 (Gen 72)** and **1.62 (Gens 150, 156, 158, 159)**. The primary differentiator is the precision of the mutations: **Gen 72** uses index-pair-specific "Peak Pressure" moves, whereas the 1.62 cohort relies on broader convolution gradients or mass migration.
+*   **Convergence at High Resolution:** All programs that achieved scores below 1.70 (**Gens 150, 151, 154-159**) allocated the largest portion of their 10-second budget (typically 50% or 5.0s) to the final $n=768$ resolution. Programs that fail to allocate sufficient time to the final resolution cannot perform enough "surgical" iterations to flatten the final convolution spikes.
+*   **Symmetry and Score Correlation:** There is a strong correlation between strict symmetry enforcement in the final 25% of the time budget and achieving scores below 1.65. **Gen 157** (1.69) and **Gen 152** (2.00) showed weaker symmetry or gradient logic compared to the 1.60-1.62 group, which used symmetry as a dimensionality reduction tool in the final search phase.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Mass-Preserving Peak-to-Valley Migration**: Build upon the "Peak Pressure Move" and "Efficiency Boost" by combining them into a single deterministic step. Identify indices $i, j$ whose product $A_i \cdot A_j$ contributes most to the maximum convolution value and simultaneously identify indices whose contributions are minimal; subtract a small multiplicative $\epsilon$ from the peak-contributing elements and redistribute that exact sum to the valley-contributing elements. This maintains the sequence sum $\sum A = n$ internally while directly flattening the $L_\infty$ norm of the convolution.
+
+2. **Escalate Softmax Beta for "Nanosurgery" (500-1000)**: To move beyond the 1.60 plateau, increase the softmax $\beta$ from the current maximum of 200 to at least 500 during the final $n=768$ resolution. Use the numerically stable identity $w = \exp(\beta \cdot (C / \max(C) - 1.0))$ to create an ultra-precise mask that isolates only the specific sequence elements responsible for the absolute peak. This allows the optimizer to shave the primary spike without inducing collateral damage (jitter) in the rest of the smooth envelope.
+
+3. **Switch to Deterministic Half-Length Optimization in the Final Phase**: Since the theoretical and empirical optima are symmetric, once the program enters the final 30% of the time budget or the $n=768$ resolution, strictly optimize only the first $n/2$ elements and enforce symmetry via `seq[n//2:] = seq[:n//2][::-1]`. By effectively halving the search dimensionality, the algorithm can perform twice as many "surgical" iterations per second at the most computationally expensive resolution.
+
+4. **Apply Gradient Smoothing via Gaussian Kernels**: Before applying a "Peak Pressure" or "Softmax Gradient" update to the sequence, convolve the modification vector (the delta or multiplicative mask) with a narrow Gaussian kernel ($\sigma \approx 1-3$ indices). This prevents the "nanosurgery" moves from introducing high-frequency jaggedness or "spikes" in the sequence envelope, which often create new, secondary convolution peaks that stall progress near the 1.60 threshold.
+
+5. **Transition from Fixed Time-Shares to Progress-Based Upscaling**: Replace the hardcoded `time_shares` ladder with a "patience" trigger for resolution increases. Set a threshold for improvement (e.g., if the best score hasn't improved by 0.1% in 100 iterations); only then upscale from $n=256$ to $n=512$.

+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+# Detailed Performance Analysis and Optimization Insights
+
+## Successful Algorithmic Patterns
+
+*   **Surgical Peak Pressure Moves (Contribution-Based Multiplicative Scaling):** The current best program (**Gen 72**, score 1.60) achieves its performance by identifying the specific index pair $(i, j)$ such that $i+j$ results in the absolute maximum convolution peak. It then applies multiplicative reductions directly to these contributing elements. This is more precise than standard gradient descent because it identifies the source of the $L_\infty$ norm rather than just the direction of descent.
+*   **Dynamic High-Beta Softmax Weighting:** High-performing programs (**Gen 72**, score 1.60; **Gen 164**, score 1.61) utilize a softmax-weighted gradient proxy with a $\beta$ parameter that increases over time (scaling from 30 up to 200). This "nanosurgical" approach ensures that as the optimization nears the deadline, the focus narrows exclusively on the highest remaining spikes in the convolution, preventing the "flattening" of already optimal sections.
+*   **Multi-Resolution Scaling with Laddered Time Allocation:** All successful programs in the 1.60-1.63 range (**Gens 72, 162, 163, 164**) utilize a laddered resolution strategy (128 → 256 → 512 → 768). The most effective programs allocate the largest chunk of time (50% or more) to the final 768-length resolution, using `np.interp` to carry over the global "envelope" shape from lower resolutions.
+*   **Targeted "Mass Migration" and "Efficiency Boosts":** Programs breaking the 1.65 barrier (**Gen 162**, score 1.63; **Gen 163**, score 1.62) implement logic that identifies indices contributing the least to the convolution peaks ("valleys") and migrates mass to them from the "peaks." **Gen 72** achieves this via an "Efficiency Boost" mutation that increases values at indices with the lowest gradient impact, maintaining the sequence sum while lowering the maximum peak.
+
+## Ineffective Approaches
+
+*   **Runtime Environment Neglect (Missing Imports):** A significant number of programs in the current generation (**Gens 160, 161, 165, 166, 168, 169**) achieved a score of 0.0 despite mathematically sophisticated logic (e.g., "Mirror Descent," "Spectral Refinement"). This was due to the omission of `import numpy` and `import time` within the script. This confirms that local optimization logic is irrelevant if basic runtime dependencies are not satisfied.
+*   **Weak "Nanosurgical" Updates:** **Gen 167** achieved a value of 2.00, which is the baseline for a uniform sequence. While it claimed to use "nanosurgical gradient updates," the result suggests that the updates were either too small to overcome the uniform initialization or lacked the multiplicative "shaving" intensity required to disrupt the flat profile.
+*   **Over-reliance on Global Spectral Mutators:** While spectral smoothing (FFT) helps maintain the "envelope," programs that rely too heavily on it without index-specific "surgical" moves fail to achieve scores below 1.65. The $L_\infty$ norm of the convolution is sensitive to local fluctuations that global spectral methods often smooth over rather than specifically target.
+
+## Implementation Insights
+
+*   **Scale-Invariant Normalization:** The current best program (**Gen 72**) and **Gen 162** use a `_normalize_scale` function to enforce $\sum A_i = n$. This stabilizes the objective function $2n \cdot \max(C) / (\sum A)^2$ by effectively reducing it to $2 \cdot \max(C) / n$, allowing the optimizer to focus on the shape of the sequence rather than its magnitude.
+*   **Symmetry Enforcement as a Late-Stage Constraint:** Successful strategies (**Gen 72**, **Gen 164**) do not enforce symmetry 100% of the time at the beginning. **Gen 72** uses a 40% probability for symmetry in early stages, increasing to 100% (or using a weighted average `(seq + seq[::-1]) / 2`) in the final 25% of the time budget. This allows the search to explore asymmetric configurations that might bypass local minima before settling into the symmetric optimal form.
+*   **Power-Law Seeding (Arc-Sine Approximation):** Initializing with $x^{-p}$ (where $p \approx 0.5$) or symmetric versions of these power laws (**Gen 162, 164**) consistently places the starting point closer to the 1.57-1.60 range than random or sinusoidal seeds.
+
+## Performance Analysis
+
+*   **The 1.60 Floor:** There is a notable performance wall at 1.60. The current best (**Gen 72**) reached 1.60, while **Gen 164** reached 1.61 and **Gen 163** reached 1.62. The differentiator is the transition from "gradient-inspired mutations" to "summand-specific surgical moves."
+*   **Efficiency of Multiplicative vs. Additive Changes:** The top-performing **Gen 72** prefers multiplicative scaling (`seq[idx] *= (1.0 - sigma)`) for peak reduction. This is inherently more stable than additive changes for non-negative sequences, as it naturally prevents values from dropping below zero and scales the "shaving" relative to the current value's magnitude.
+*   **Resolution and Convergence Correlation:** Programs that failed to include the multi-resolution ladder or failed to upscale correctly to $n=768$ (like the 0.0 score failures in **Gen 161**) cannot compete with the 1.60-1.63 cluster. High-resolution optimization is required to "sand down" the final high-frequency spikes in the convolution profile.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Mass-Preserving Peak-to-Valley Migration**: Integrate the "Peak Pressure Move" and "Efficiency Boost" into a single deterministic operation. Subtract a multiplicative $\epsilon$ from the indices contributing most to the convolution peak and redistribute that exact amount of mass to the indices identified by the gradient as "valleys." This maintains the internal sequence sum $\sum A = n$ more naturally than global normalization alone, directly flattening the $L_\infty$ profile without shifting the overall scale.
+
+2. **Escalate Softmax Beta for "Nanosurgery" (500-1000)**: To break the 1.60 barrier, increase the softmax $\beta$ from the current max of 200 to 1000 during the final $n=768$ resolution. Use the numerically stable formula $w = \exp(\beta \cdot (C / \max(C) - 1.0))$ to create an ultra-precise mask that isolates only the specific sequence elements responsible for the absolute peak. This allows the optimizer to shave the primary spike with extreme precision, avoiding the collateral jitter that limits progress at lower beta values.
+
+3. **Transition to Strict Half-Length Optimization in the Final Phase**: Once the program reaches the $n=768$ resolution or the final 30% of the time budget, switch to optimizing only the first $n/2$ elements and enforce symmetry via `seq[n/2:] = seq[:n/2][::-1]`. By effectively halving the search dimensionality, the algorithm can perform twice as many "surgical" iterations per second at the most computationally expensive scale, which is critical for finding the fine-grained refinements needed below 1.60.
+
+4. **Apply Gaussian Smoothing to Mutation Deltas**: Before applying a "Peak Pressure" or "Softmax Gradient" update to the sequence, convolve the modification vector with a narrow Gaussian kernel ($\sigma \approx 1-2$ indices). This prevents "nanosurgery" from introducing high-frequency jaggedness or local "spikes" in the sequence envelope, which frequently create new, secondary convolution peaks that stall convergence in the final iterations.
+
+5. **Utilize Progress-Based Adaptive Resolution Upscaling**: Replace the fixed `time_shares` ladder with a "patience" trigger for resolution increases (e.g., upscale from $n=256$ to $n=512$ only if the best score hasn't improved by 0.05% in 50 iterations). This ensures the global "macro-envelope" is fully optimized at lower, computationally cheaper scales before committing the majority of the remaining time budget to high-precision fine-tuning at $n=768$.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Surgical Peak Pressure via Index Attribution:** The current best program (**Gen 72**, score 1.60) identifies the specific index pairs $(i, j)$ that contribute most to the $L_\infty$ norm (the maximum convolution peak). By applying multiplicative reductions (`seq[idx] *= (1.0 - sigma)`) directly to these contributing elements, it achieves a more precise descent than general gradient proxies.
+*   **Precision "Nanosurgery" with Softmax Gradient Proxies:** Programs like **Gen 178** (score 1.61) and **Gen 72** (score 1.60) use a softmax-weighted gradient approximation. By setting a high $\beta$ (scaling from 30 to 200 throughout the run), the mutation focuses specifically on the highest convolution spikes. **Gen 178** specifically combined this with mass-preserving migrations from peaks to valleys to maintain the sequence sum while lowering the objective.
+*   **Multi-Resolution Scaling with Laddered Time Allocation:** All high-performing programs (**Gen 72, 173, 175, 178**) utilize a resolution ladder (128 → 256 → 512 → 768). They allocate a larger portion of the search budget (50% or more) to the final 768-element resolution, using `np.interp` to translate the low-frequency "envelope" found at lower resolutions into a high-resolution starting point.
+*   **Power-Law Seeding and Symmetry Hardening:** **Gen 173** (score 1.62) and **Gen 178** (score 1.61) successfully leveraged power-law initializations (e.g., $(n-i)^{-0.5}$) and progressive symmetry enforcement. Starting with asymmetric configurations allows for better exploration of the search space, while "hardening" the symmetry (e.g., `(seq + seq[::-1]) / 2`) in the final 25% of the time budget ensures the final result complies with the symmetric optimal form.
+
+## Ineffective Approaches
+
+*   **Omission of Runtime Dependencies:** A recurring catastrophic failure in the latest generation (**Gens 171, 172, 174, 176, 177, 179**) resulted in scores of 0.0. These programs implemented sophisticated "Surgical Gradient" logic but failed because they did not include `import numpy` or `import time` within the execution scope. 
+*   **Basic Syntax Errors in Final Assignments:** **Gen 170** (score 0.0) failed due to a simple typo (`valal` instead of `val`) in the final assignment block. This highlights that even the most advanced signal processing strategies (like FFT-based mutations) are nullified by lack of basic code validation.
+*   **Numerical Instability in High-Beta Softmax:** **Gen 177** and **Gen 179** encountered issues with high-beta exponential calculations. While a high $\beta$ is necessary for "nanosurgery," if the implementation does not use the stable softmax trick (e.g., `exp(beta * (c/max_c - 1))`), it results in floating-point overflows and runtime failures.
+*   **Over-reliance on Global Spectral Methods:** While FFT-based mutations help maintain the "smoothness" of the sequence, they often fail to address the specific local spikes that define the $L_\infty$ norm. Programs that favor global spectral smoothing over index-specific surgical moves (as seen in the feedback for **Gen 174**) struggle to break the 1.65 performance barrier.
+
+## Implementation Insights
+
+*   **Multiplicative vs. Additive Updates:** **Gen 72** (score 1.60) utilizes multiplicative scaling for its "Peak Pressure" moves. This is more effective for non-negative sequences as it naturally prevents values from dropping below zero and scales the adjustment relative to the element's current importance.
+*   **Gradient Proxy via Convolution:** Successful programs (**Gen 72, 178**) calculate the gradient of the convolution peak by convolving the error weights $w$ with the reversed sequence `seq[::-1]`. This identifies the sensitivity of the maximum peak to each coefficient in the sequence $A$.
+*   **Scale-Invariant Normalization:** The most effective programs use a custom normalization function (like `_normalize_scale` in **Gen 72**) to keep $\sum A_i = n$. This stabilizes the objective function $2n \cdot \max(C) / (\sum A)^2$ by reducing it to $2 \cdot \max(C) / n$, allowing the mutation logic to focus entirely on the shape of the coefficient distribution.
+*   **Mass-Preserving Migrations:** **Gen 175** and **Gen 178** implemented logic to "migrate" mass from indices contributing to peaks to "valleys" (indices contributing the least to the convolution). This redistribution is more efficient than random perturbations because it directly targets the minimax objective.
+
+## Performance Analysis
+
+*   **The 1.60 Performance Ceiling:** There is a significant performance plateau at 1.60. **Gen 72** remains the benchmark at 1.60, with **Gen 178** (1.61) and **Gen 173/175** (1.62) trailing closely. The marginal gains at this level are achieved through the precision of "surgical" moves rather than new global search heuristics.
+*   **Impact of Multi-Resolution Ladder:** Programs that do not scale from $N=128$ to $N=768$ fail to reach the 1.60-1.63 range. The ladder strategy allows the algorithm to find a coarse optimal shape quickly and then refine the high-frequency components at the target resolution.
+*   **Correlation between Symmetry and Score:** While symmetry is a characteristic of the optimal solution, enforcing it too strictly in early search phases leads to local minima. The transition from 40% symmetry probability to 100% late-stage symmetry (seen in **Gen 72**) is a key differentiator between the 1.60-1.62 cluster and higher-value results.
+*   **Success Rate of Sophisticated Heuristics:** Despite the sophistication of "Surgical Gradient Redistribution" and "Spectral Smoothing," the high failure rate (70% of the recent generation) due to runtime errors suggests that implementation robustness (imports, error handling, syntax) is currently the primary bottleneck to surpassing the 1.60 score.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Numerically Stable High-Beta Softmax for Nanosurgery**: To break the 1.60 performance ceiling, escalate the softmax $\beta$ to 1000 during the final $N=768$ resolution phase using the stable formula `np.exp(beta * (c / np.max(c) - 1.0))`. This ultra-high precision mask allows the optimizer to isolate and subtract mass from only the exact sequence elements responsible for the $L_\infty$ peak, avoiding the collateral "jitter" at lower $\beta$ values that often prevents fine-grained convergence.
+
+2. **Execute Mass-Preserving Peak-to-Valley Migration**: Instead of independent multiplicative reductions or increases, implement a "Migration Move" that subtracts mass from indices contributing to the convolution peak and redistributes it to the "valleys" (indices with the lowest gradient sensitivity). This deterministic redistribution maintains the internal sequence sum $\sum A = n$ more naturally than global normalization, directly flattening the $L_\infty$ profile without shifting the overall scale of the sequence.
+
+3. **Transition to Strict Half-Length Optimization in the Final Phase**: Once the program reaches the $N=768$ resolution or the final 30% of the time budget, switch to optimizing only the first $n/2$ elements and enforce symmetry via `seq[n/2:] = seq[:n/2][::-1]`. Halving the search dimensionality in the most computationally expensive phase allows the algorithm to perform significantly more "surgical" iterations per second, focusing the remaining budget on refining the symmetric form known to be optimal.
+
+4. **Apply Gaussian Smoothing to Mutation Deltas**: Convolve update vectors (like the gradient proxy or peak-pressure adjustments) with a narrow Gaussian kernel ($\sigma \approx 1-2$ indices) before applying them to the sequence. This smoothing prevents "nanosurgery" from introducing high-frequency jaggedness or local "spikes" in the sequence envelope, which frequently create new, secondary convolution peaks that stall progress in late-stage optimization.

+5. **Utilize Progress-Based Adaptive Resolution Upscaling**: Replace the fixed `time_shares` ladder with a "patience" trigger that upscales the resolution (e.g., from $N=256$ to $N=512$) only when the best score has failed to improve by a threshold (e.g., 0.02%) for 100 iterations. This ensures the global "macro-envelope" of the sequence is fully converged at computationally cheaper scales before committing the majority of the time budget to high-resolution refinement.

+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+This analysis examines the performance and implementation of programs optimizing the autocorrelation (AC) inequality $2n \cdot \max(C) / (\sum A)^2$, where $C$ is the autoconvolution of sequence $A$.
+
+## Successful Algorithmic Patterns
+
+*   **High-Beta Surgical Mirror Descent:** The most successful program (**Gen 188**, score 1.60) utilizes a "Surgical Mirror Descent" operator. This combines a multiplicative update rule with a high-beta softmax ($\beta$ scaling from 30 to 200) to isolate specific indices contributing to convolution peaks. By convolving these soft-max weights with the reversed sequence, the algorithm identifies exactly which coefficients require reduction to lower the $L_\infty$ norm of the convolution.
+*   **Mass-Preserving Peak-to-Valley Migration:** Programs consistently breaking the 1.62 barrier (**Gen 180, 186, 187, 188**) implement "Peak-to-Valley" migration. Instead of random noise, these programs redistribute mass from indices causing peaks to indices causing valleys. **Gen 187** (1.61) specifically used "Surgical Mass Migration" to flatten the convolution profile without changing the sequence sum, maintaining numerical stability in the objective function.
+*   **Progressive Resolution Laddering:** All top-tier results (**Gen 180–189**) utilize a multi-resolution approach, scaling from $n=128$ to $n=768$. The successful pattern involves finding a coarse "envelope" at low resolutions and using `np.interp` to provide a high-fidelity starting point for final refinement. **Gen 188** (1.60) allocated the final 50% of its budget to the 768-element resolution, which is critical for precision.
+*   **Symmetry Hardening:** The current best program (**Gen 188**) and its predecessors allow for asymmetric exploration early in the search (approx. 40% symmetry probability) but "harden" the symmetry (enforcing `seq = (seq + seq[::-1]) / 2`) in the final 25% of the time budget. This approach exploits the fact that the optimal solution is likely symmetric while avoiding early stagnation in symmetric local minima.
+
+## Ineffective Approaches
+
+*   **Excessive Spectral Smoothing:** While FFT-based mutations help maintain a smooth sequence envelope, an over-reliance on global spectral damping leads to higher scores. **Gen 185** (1.64) and **Gen 189** (1.62) used FFT-based smoothing but were outperformed by programs like **Gen 188** (1.60) that prioritized index-specific "nanosurgery" over global frequency filtering.
+*   **Unstable Softmax Implementations:** Programs from previous generations failed due to floating-point overflows in high-beta calculations. The current cohort avoided this by using the "stable softmax" trick: `np.exp(beta * (c / max_c - 1.0))`. Programs that did not apply this normalization to the convolution weights $c$ before exponentiating (observed in earlier failures) could not reliably target the highest peaks.
+*   **Coarse-Grained Perturbations at High Resolution:** **Gen 181** (2.00) achieved a significantly worse score because it used broad mutation operators at high resolution. Targeted moves (perturbing 1–2 elements based on gradient sensitivity) are required at $n=768$; large block perturbations at this stage disrupt the delicate balance needed to keep all convolution peaks below a certain threshold.
+
+## Implementation Insights
+
+*   **Multiplicative vs. Additive Updates:** **Gen 188** (1.60) and **Gen 180** (1.61) demonstrate that multiplicative updates (`seq[idx] *= (1.0 - sigma)`) are superior for this task. They naturally preserve the non-negativity of the sequence and provide scaling proportional to the coefficient's magnitude, which is more effective for the scale-invariant AC objective.
+*   **Power-Law Seeding:** Theoretical seeding with $x^{-0.5}$ distributions is a consistent feature of programs reaching the 1.60-1.61 range (**Gen 180, 183, 186**). Starting the search with a sequence that already yields a relatively flat convolution allows the gradient-based moves to focus on micro-refinements rather than discovering the global shape.
+*   **Gradient Attribution via Convolution:** The key to "Surgical" moves is the calculation of the sensitivity gradient. By convolving the error weights $w$ (where $w$ is large at convolution peaks) with the reversed sequence `seq[::-1]`, the programs (e.g., **Gen 184, 188**) calculate the derivative of the max-convolution with respect to each input coefficient $A_i$.
+
+## Performance Analysis
+
+*   **The 1.60 Barrier:** There is a significant performance cluster between 1.60 and 1.62. **Gen 188** matched the previous benchmark of 1.60. Achieving this score requires a perfect balance between global resolution scaling and local "nanosurgery" on the convolution peaks.
+*   **Resolution and Efficiency:** Programs that scaled resolutions linearly (e.g., 128 -> 256 -> 512 -> 768) outperformed those that started at higher resolutions. The time spent at $n=128$ is highly efficient for determining the optimal power-law-like decay, which then persists as the "envelope" for $n=768$.
+*   **Score Distribution:** The difference between 1.60 (**Gen 188**) and 1.64 (**Gen 185**) is primarily driven by the precision of the peak-reduction moves. The 1.60 programs spend more iterations performing targeted mass-migration and less time on random noise or block mutations. All programs reaching 1.60-1.61 successfully managed the 10-second budget by using vectorized NumPy operations for the heavy convolution and FFT steps.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Ultra-High Beta "Nanosurgery" for Peak Isolation**: Escalate the softmax $\beta$ from the current maximum of 200 up to 1000 during the final $n=768$ resolution phase. Using the numerically stable formula $\exp(\beta \cdot (c / \max(c) - 1.0))$, an ultra-high $\beta$ transforms the gradient into a "surgical" mask that isolates only the exact coefficients responsible for the $L_\infty$ norm peak, preventing the collateral "jitter" that often limits convergence near the 1.60 barrier.
+
+2. **Execute Coupled Mass-Preserving Migration**: Replace independent multiplicative increases and decreases with a "Migration Move" that subtracts mass from indices with the highest gradient sensitivity (peaks) and adds it to indices with the lowest sensitivity (valleys). This deterministic redistribution flattens the convolution profile while keeping the sequence sum $\sum A$ perfectly constant, maintaining numerical stability and objective scale without relying on global normalization.
+
+3. **Transition to Half-Length Search for Efficiency**: In the final 30% of the time budget or once reaching $n=768$, switch to optimizing only the first $n/2$ elements and enforce symmetry via `seq[n/2:] = seq[:n/2][::-1]`. Halving the search dimensionality in the most computationally expensive phase allows the algorithm to perform nearly double the iterations per second, focusing the remaining budget on refining the symmetric form which has proven to be optimal in high-performing programs.
+
+4. **Apply Gaussian Smoothing to Mutation Deltas**: Convolve the surgical update vectors (gradient-based adjustments) with a narrow Gaussian kernel ($\sigma \approx 1.5$ indices) before applying them to the sequence. This smoothing prevents targeted mutations from introducing high-frequency "jaggedness" or local spikes in the sequence envelope, which typically generate new, secondary convolution peaks that cause the optimizer to stall in late-stage refinement.
+
+5. **Utilize Progress-Based Adaptive Resolution Upscaling**: Replace the fixed `time_shares` ladder with a "patience" trigger that upscales the resolution (e.g., from 512 to 768) only when the best score has failed to improve by a threshold (e.g., 0.01%) for 50 iterations. This ensures the macro-envelope of the sequence is fully converged at computationally cheaper scales before committing the bulk of the 10-second budget to high-fidelity, high-cost iterations at $n=768$.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+This analysis of the AlphaEvolve AC inequality task examines the progression from standard stochastic optimization to sophisticated multi-resolution searches and targeted heuristic moves.
+
+### Successful Algorithmic Patterns
+
+*   **Targeted Peak-Reduction Heuristics**: The most effective optimization strategy involves identifying the specific sequence indices that contribute most to the objective function's penalty. The **Current Best Program (Gen 9, score 1.63)** and **Gen 14 (score 1.64)** utilize a "Peak Reduction" move: identifying the index $p$ of the maximum convolution value and reducing the elements $s[i]$ where the product $s[i] \cdot s[p-i]$ is maximized. This directly targets the $L_\infty$ norm of the convolution, which is the most sensitive part of the objective ratio.
+*   **Progressive Multi-Resolution Refinement**: Successful programs across all generations (Gen 9, 13, 14, 15, 18) consistently use a multi-resolution schedule (e.g., scaling from $n=128 \to 256 \to 512 \to 768$). This allows the search to find a stable global shape at low dimensions and refine high-frequency details at higher resolutions. **Gen 13 (score 1.68)** and **Gen 18 (score 1.67)** used this to escape local minima that single-resolution searches (like Gen 0) could not.
+*   **Symmetry Enforcement and Seed Diversity**: The **Current Best Program (Gen 9)** and **Gen 14** incorporate symmetry enforcement (averaging a sequence with its reverse) and diverse initial seeds (power laws, sine waves, and Gaussians). **Gen 15 (score 1.70)** demonstrated that low-frequency spectral seeding helps establish the "smooth" global structure necessary for low auto-convolution peaks.
+*   **Softmax Gradient Approximation**: Using a softmax-based proxy to differentiate the non-smooth $L_\infty$ peak was successfully employed by **Gen 15** and **Gen 17 (score 1.71)**. While slightly less effective than the discrete "Peak Reduction Move," it provided a more stable optimization path than pure random mutations.
+
+### Ineffective Approaches
+
+*   **Missing Dependency Management**: Multiple programs with sophisticated logic, specifically **Gen 16** and **Gen 19**, failed completely (score **0.0**) due to the omission of essential imports like `numpy` and `time`. This underscores that architectural sophistication is irrelevant without basic execution stability.
+*   **Pure Stochastic Noise at High Resolution**: Programs that relied primarily on block or scattered perturbations without peak-targeting heuristics (like the early iterations and **Gen 11**) struggled to improve beyond the **1.74** threshold. Without targeted moves, the probability of randomly hitting the indices contributing to the convolution maximum is extremely low as $n$ increases to 768.
+*   **Overshooting/Scaling Issues**: Programs that failed to strictly normalize sequences or used hardcoded schedules (Gen 16) often produced sequences that did not meet the length criteria or had unstable objective ratios, leading to validation failures.
+
+### Implementation Insights
+
+*   **Heuristic-Gradient Hybridization**: The **Current Best Program (Gen 9)** excels by blending discrete heuristics with a decaying mutation rate (`sigma`). The mutation magnitude scales with time (`0.15 * (1.0 - elapsed/budget)`), ensuring that the search transitions from broad exploration of the sequence space to fine-grained local optimization of the peaks.
+*   **Effective Upsampling via Interpolation**: The use of `np.interp` to translate sequences across resolutions (as seen in **Gen 9, 13, and 14**) is critical. It preserves the optimized "energy distribution" of the sequence, allowing the higher-resolution stage to start from a near-optimal low-frequency state rather than re-optimizing from scratch.
+*   **Mathematical Normalization**: The most stable programs utilize a `_normalize_scale` function that clips values to non-negative and scales the sum to equal the sequence length. This maintains the denominator of the objective function ($(\sum a)^2$) as a constant ($n^2$), simplifying the problem to the minimization of the convolution peak.
+*   **Peak Sensitivity Calculation**: The implementation in **Gen 14** and **Gen 18** calculates the contribution to a peak via `contrib = seq[i_range] * seq[p-i_range]`. This specific mathematical insight allows the program to perform "surgical" mutations that are far more effective than general smoothing or local scaling.
+
+### Performance Analysis
+
+*   **The 1.63 Frontier**: The **Current Best Program (Gen 9)** maintains the leading score of **1.63**. **Gen 14** reached **1.64** using nearly identical peak-reduction logic, suggesting that the combination of resolution scaling and peak-targeted mutations has hit a performance plateau given the current time budget.
+*   **Resolution vs. Quality**: While **Gen 10** attempted a sequence length of 800 and achieved **1.73**, the programs restricted to the 768 limit (like **Gen 14 at 1.64**) outperformed it. This indicates that the strategy of refinement is more impactful than simply increasing sequence length.
+*   **Analytic vs. Heuristic Performance**: Heuristic moves (Peak Reduction) currently outperform formal gradient-based approaches (Softmax proxies). **Gen 9 (1.63)** and **Gen 14 (1.64)**, which use direct index targeting, consistently beat **Gen 15 (1.70)** and **Gen 17 (1.71)**, which use softmax-weighted gradients. This suggests that the objective function's landscape is better navigated via discrete logic that addresses the max operator directly.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+Based on the success of the Current Best Program (Gen 9) and the analysis of previous iterations, here are five actionable recommendations for future program mutations:
+
+1.  **Top-K Peak Targeting and Denominator Boosting**: Enhance the "Peak Reduction Move" by identifying the top $k$ indices in the convolution that are within 5% of the maximum peak. Instead of reducing just one index, apply a weighted reduction to the indices contributing to all these high peaks, while simultaneously identifying "inactive" indices (those contributing least to the convolution sum) and slightly increasing their values to boost the $(\sum a)^2$ denominator without raising the numerator.
+
+2.  **Spectral-Domain (FFT) Mutations for Smoothness**: Since low-frequency structures (Gaussians, sines) are more effective than high-frequency noise, implement mutations in the frequency domain using `np.fft.rfft`. Perturb the magnitude of low-frequency components while keeping high-frequency components attenuated; this ensures the sequence remains "smooth" during mutations, which is critical for preventing the sharp peaks in the auto-convolution that degrade the objective.
+
+3.  **Adaptive "Patience-Based" Resolution Scaling**: Replace the fixed time-slices for resolutions (128, 256, 512, 768) with an adaptive schedule. Implement a "stagnation counter" that triggers an upsample via `np.interp` only after the objective value fails to improve by a threshold ($1e-5$) for 50 consecutive iterations, ensuring the search spends minimal time on low-res global shaping and maximizes time on high-res local refinement.
+
+4.  **Symmetry-Preserving Local Search**: Incorporate a mutation that explicitly enforces symmetry ($s = (s + \text{reverse}(s)) / 2$) every few iterations, as the auto-convolution of a symmetric sequence is mathematically more stable. Combine this with a targeted local search that focuses on the central indices of the sequence, as the auto-convolution peak $p$ frequently occurs near $n$ in symmetric-like distributions.
+
+5.  **Softmax-Weighted Sensitivity Dampening**: Improve upon the discrete "Peak Reduction" by calculating a sensitivity vector $V$ where each $V[i]$ is the sum of contributions to the convolution peaks, weighted by a softmax of the convolution values. Use this vector to apply a proportional dampening factor to the sequence ($s_{new} = s \cdot (1 - \sigma \cdot V)$), allowing the program to perform "soft" global cooling of all potential peaks simultaneously rather than jumping between individual indices.

+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+The following analysis extracts optimization insights from the evaluation of programs targeting the Autocorrelation (AC) inequality, building upon previous global observations and focusing on the current best-performing implementation (**Gen 190/188**).
+
+### Successful Algorithmic Patterns
+
+*   **Annealed High-Beta Surgical Gradient:** The most successful pattern (achieving 1.60 in **Gen 190**) involves a "Surgical Mirror Descent" operator. This method uses a stable softmax-weighted gradient where $\beta$ is annealed from 30 to 200 over the run. By convolving the weighted error (representing convolution peaks) with the reversed sequence, the algorithm calculates a precise sensitivity map, allowing it to target only the coefficients that contribute to the $L_\infty$ norm.
+*   **Mass-Preserving Migration & Log-Gradients:** Programs achieving scores of 1.60–1.62 (**Gen 190, 194, 198**) utilize "Peak-to-Valley" migration. Instead of purely reductive moves, these algorithms shift mass from indices causing convolution peaks to those causing valleys. **Gen 198** specifically utilized log-gradients of the convolution to refine this migration, which helps flatten the convolution profile while maintaining the sequence sum.
+*   **Progressive Resolution Scaling with Symmetry Hardening:** All top-performing programs (**Gen 190, 192, 194, 198**) utilize a multi-resolution ladder (scaling from 128 to 768). The strategy involves spending the final 50% of the time budget at $n=768$. **Gen 190** also implements "Symmetry Hardening," where symmetry is enforced more strictly (increasing from 40% to 100% probability) as the resolution increases, preventing the search from being trapped in suboptimal asymmetric local minima.
+*   **Power-Law and Gaussian Seeding:** Starting with a theoretically grounded shape (like $x^{-0.5}$ in **Gen 190** and **Gen 192**) provides a "flat" initial convolution profile. This allows the subsequent gradient-based "nanosurgery" to focus on micro-optimizations rather than trying to discover the global envelope from a random state.
+
+### Ineffective Approaches
+
+*   **Missing Core Dependencies:** A recurring failure mode in the current generation (**Gen 193, 195, 199**) was the omission of `import numpy` or `import time` within the local scope or global program. Despite having sophisticated logic (e.g., "Symmetric Nanosurgery"), these programs failed validation immediately with a score of 0.0.
+*   **Numerical Instability in High-Beta Weighting:** While high-beta softmax is effective, implementations that fail to use the "stable softmax trick" ($c/max\_c - 1.0$) likely suffer from floating-point overflows. **Gen 197** likely failed validation or convergence due to such instability in its "Peak Isolation" logic when calculating exponential weights.
+*   **Over-reliance on Global Spectral Mutations:** While spectral damping (FFT-based) helps maintain a smooth sequence, programs that relied too heavily on it without index-specific surgical moves (implied by the feedback for **Gen 189** and observed in the lower performance of **Gen 194** at 1.62 vs. 1.60) failed to reach the best-known values. Global moves at high resolution disrupt the delicate balance of the convolution.
+
+### Implementation Insights
+
+*   **Multiplicative Multi-Index Updates:** The current best program (**Gen 190**) uses multiplicative updates: `seq[target_idx] *= (1.0 - sigma * scale)`. This is superior to additive updates for this task because it naturally maintains non-negativity and scales the perturbation relative to the coefficient magnitude, which is more effective for a scale-invariant objective.
+*   **Symmetry-Aware Perturbation:** In **Gen 190**, perturbations are applied symmetrically if the sequence is already symmetric (`if was_symmetric: seq[n - bstart - blen : n - bstart] += delta[::-1]`). This preserves the structural properties of the sequence throughout the mutation process, drastically reducing the search space.
+*   **Stable Gradient Attribution:** The "nanosurgery" effective in **Gen 190** and **Gen 198** is powered by `grad = np.convolve(w, seq[::-1], mode='full')[n-1 : 2*n-1]`. This specific implementation of the gradient calculation correctly identifies how each $A_i$ influences the convolution peaks $C_k$, which is the crucial differentiator for reaching the 1.60 threshold.
+
+### Performance Analysis
+
+*   **The 1.60 Barrier:** **Gen 190** (and its predecessor **Gen 188**) represents the current performance ceiling. Achieving this score requires the precise integration of power-law initialization, resolution laddering, and annealed surgical mirror descent.
+*   **Resolution and Efficiency:** There is a clear correlation between the time spent at $n=768$ and the final score. Programs like **Gen 192** (1.64) and **Gen 194/198** (1.62) used similar techniques but achieved slightly worse results than **Gen 190** (1.60), likely due to less efficient time allocation between the "global search" (low resolution) and "fine refinement" (high resolution) phases.
+*   **Success Rate of Sophisticated Heuristics:** The data shows a high "failure-to-execute" rate for complex programs. While the "Surgical Mirror Descent" approach is the most successful, it is also the most prone to implementation errors (missing imports, numerical overflow), as seen in the 0.0 scores of **Gen 191, 193, 195, 196, 197, and 199**. Successful programs are those that balance sophisticated gradient heuristics with robust, vectorized NumPy implementations.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Explicit Half-Length Search for the $n=768$ Phase**: Since symmetry is nearly 100% enforced in the final stages of the best program, explicitly reduce the search space by optimizing only the first $n/2$ elements and reflecting them to form the full sequence. This effectively doubles the iteration speed at the most computationally expensive resolution, allowing for deeper refinement of the symmetric profile which has consistently yielded the 1.60 score.
+
+2. **Execute Coupled "Peak-to-Valley" Mass Migration**: Replace the independent multiplicative updates (currently $m\_type < 0.50$ and $m\_type < 0.80$) with a single operator that moves mass directly from indices with high gradient sensitivity to those with low sensitivity. By subtracting a small delta from "peak-contributing" indices and adding it to "valley-filling" indices, you maintain a constant $\sum A$ and prevent the optimizer from drifting into regions of the search space that require global re-normalization.
+
+3. **Escalate to Ultra-High Beta (1000+) with Numerical Stability**: Extend the softmax $\beta$ annealing range from the current max of 200 up to 1000 or higher during the final 20% of the budget. To prevent overflow, strictly use the `np.exp(beta * (c / max_c - 1.0))` formulation; this "surgical" precision isolates only the absolute maximum of the convolution, ensuring that late-stage mutations target the $L_\infty$ norm exclusively without introducing collateral noise in the rest of the sequence.
+
+4. **Apply Gaussian Smoothing to Gradient Updates**: Before applying the calculated gradient to the sequence, convolve the update vector with a narrow Gaussian kernel ($\sigma \approx 1.0 - 2.0$). This prevents "nanosurgery" from creating high-frequency "jaggedness" or local spikes in the sequence envelope, which often lead to new, secondary convolution peaks that stall convergence near the 1.60 barrier.
+
+5. **Transition to Patience-Based Adaptive Resolution Scaling**: Replace the fixed `time_shares` ladder with a trigger that upscales the resolution only when the objective has failed to improve by a small epsilon (e.g., $10^{-5}$) for a fixed number of iterations (patience). This ensures that the macro-envelope of the sequence is fully optimized at lower resolutions (128, 256) before committing the majority of the time budget to the high-cost $n=768$ refinement.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+The analysis of the Generation 20-29 program evaluations reveals a significant performance breakthrough, with the best objective value improving from **1.63 (Gen 9)** to **1.61 (Gen 29)**. The primary driver of this improvement is the transition from heuristic "peak reduction" moves to sophisticated **sensitivity-driven gradient approximations** using exponential weighting.
+
+### Successful Algorithmic Patterns
+
+*   **Sensitivity-Driven Multi-Peak Reduction**: The most successful programs (Gen 29, 1.61; Gen 28, 1.62) replaced simple index-targeting with a weighted gradient approach. By calculating a weight vector $w = \exp(40.0 \cdot (c / \max(c) - 1.0))$ from the convolution $c$, programs identify all indices contributing to the peak. This allows for "surgical" reductions of elements that have the highest sensitivity, outperforming the discrete "Peak Reduction Move" of previous generations.
+*   **Progressive Multi-Resolution Scheduling**: Consistency across Gen 20, 21, 23, 24, 28, and 29 confirms that scaling from $N=256 \to 512 \to 768$ is essential. This allows the algorithm to establish a low-frequency "skeleton" (minimizing the objective at lower dimensions) and then refine high-frequency details. Programs that bypassed lower resolutions or used different schedules (like Gen 22 starting at 128) were slightly less effective (1.74).
+*   **Symmetry Enforcement with Asymmetric Seeding**: The current best (Gen 29) and runner-up (Gen 28) both utilize diverse initial seeds (Power Law, Beta distributions, Sine waves) but apply symmetry enforcement (`seq + seq[::-1]`) either as a specific mutation or as a post-perturbation step. This exploits the mathematical property that low auto-convolution sequences often possess near-symmetry.
+*   **Spectral Damping and FFT Smoothing**: Incorporating frequency-domain mutations (Gen 21, score 1.65; Gen 27, score 2.00; Gen 29, score 1.61) allows the search to remove high-frequency noise that often causes localized convolution spikes, which are difficult for point-wise mutations to resolve efficiently.
+
+### Ineffective Approaches
+
+*   **Technical Omissions (Imports/Scope)**: **Gen 26** failed entirely (score 0.0) because it lacked `numpy` and `time` imports. This remains a persistent failure mode despite the high algorithmic sophistication of the proposed logic.
+*   **Unweighted Softmax/Surgical Moves**: Approaches that used standard softmax gradients or "surgical" peak reduction without the high-temperature exponential weighting (Gen 22, score 1.74; Gen 25, score 1.73) struggled to match the performance of Gen 29. Without the "sharpening" effect of the $40.0$ multiplier in the sensitivity calculation, the mutations were too diffused to effectively flatten the $L_\infty$ peak.
+*   **Over-reliance on Spectral Refinement**: While spectral moves are helpful, **Gen 27** achieved a relatively poor score of 2.00 by focusing heavily on spectral and symmetry priors without the aggressive point-wise sensitivity mutations used in Gen 29.
+
+### Implementation Insights
+
+*   **Sensitivity Gradient Calculation**: The **Current Best Program (Gen 29)** uses a specific mathematical implementation of the gradient: `grad = np.convolve(w, seq[::-1], mode='full')[n-1 : 2*n-1]`. By multiplying this gradient by the sequence itself (`sensitivity = grad * seq`), the program identifies elements where a small change results in the largest reduction in the convolution peak.
+*   **Adaptive Mutation Intensity ($\sigma$ Decay)**: Successful programs (Gen 28, 29) utilize a time-decaying $\sigma = 0.15 \cdot (1.0 - \text{progress})$. This enables broad exploration in the first 5 seconds and precise "valley-filling" in the final seconds of the 10-second budget.
+*   **Symmetry-Aware Mutations**: A key insight from Gen 29 is the conditional preservation of symmetry: `if was_symmetric and m_type < 0.95: seq = (seq + seq[::-1]) / 2.0`. This ensures that if the search enters a promising symmetric region of the search space, it remains there unless a very specific mutation intentionally breaks it.
+*   **Interpolation Strategy**: Using `np.interp` to translate sequences between resolutions (Gen 29) is more effective than simple padding, as it preserves the optimized energy distribution of the sequence across scales.
+
+### Performance Analysis
+
+*   **The 1.61 Threshold**: **Gen 29 (1.61)** represents the new state-of-the-art, marginally beating **Gen 28 (1.62)**. The difference lies in Gen 29’s specific "Sensitivity-based Compensation" move, which identifies indices contributing *least* to the convolution and boosts them to increase the sequence sum (the denominator of the objective) without increasing the peak.
+*   **Convergence Trends**: The objective values for high-performing multi-resolution programs have clustered between 1.61 and 1.69. This suggests the search space at $N=768$ is extremely flat near the optimum, and further gains require the precision of sensitivity-based moves rather than increased search iterations.
+*   **Comparison of Approaches**: Sensitivity-guided optimization (Gen 29: 1.61) is now clearly superior to both basic stochastic search (Gen 0: ~2.0+) and basic peak-reduction heuristics (Gen 9: 1.63). The use of the exponential weight provides a differentiable-like refinement capability for a non-smooth objective.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Annealed Temperature for Sensitivity Weighting**: The current best program uses a fixed multiplier of `40.0` in the exponential weight calculation $w = \exp(40.0 \cdot (c / \max(c) - 1.0))$. Implement a dynamic temperature that scales with search progress, such as $T = 20.0 + 80.0 \cdot \text{progress}$. A lower temperature early on allows the sensitivity gradient to consider broader regions of the sequence, while a higher temperature in the final stages makes mutations extremely surgical, focusing only on the absolute highest peaks.
+
+2. **Skewed Time Allocation for High-Resolution Refinement**: While the multi-resolution approach is successful, the current budget splits time equally (33% each) between $N=256, 512, 768$. Reallocate the budget to a 15%/25%/60% split. The complex $L_\infty$ landscape at $N=768$ requires significantly more iterations for the sensitivity-based moves to "flatten" the auto-convolution than the initial "skeleton" shaping at $N=256$.
+
+3. **Symmetry-Breaking and Re-Symmetrization Cycles**: The search often gets trapped in local minima within the symmetric subspace. Introduce a "jitter" mutation that intentionally breaks symmetry (e.g., `seq[:n//2] += noise`) with a small probability, followed by a period of search, and then a "re-symmetrization" step (`seq = (seq + seq[::-1])/2`). This allows the algorithm to explore asymmetric "paths" between different symmetric configurations, potentially finding a deeper global minimum.
+
+4. **Second-Order Smoothing (TV-Regularized Mutations)**: High-frequency "jitter" in the sequence often leads to localized spikes in the auto-convolution. When applying sensitivity-based reductions, apply a local 3-point Gaussian blur specifically to the targeted indices and their immediate neighbors. This ensures that the reduction is smooth rather than "point-wise," preventing the creation of new high-frequency noise that immediately creates new convolution peaks.
+
+5. **Gradient-Informed Denominator Optimization**: Improve the "Compensation Move" by targeting indices with the *absolute lowest* gradient values to increase. Instead of just scaling them, calculate the "Efficiency Ratio" $E_i = 1 / (\text{grad}_i + \epsilon)$ and use it to distribute a fixed "increase budget." This ensures that the sequence sum (the denominator of the objective) is maximized with the least possible impact on the auto-convolution peak, directly optimizing the balance between the numerator and denominator.

+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Dual-Action Softmax Gradient Refinement**: The current state-of-the-art (**Gen 30**, score 1.60) and high performers like **Gen 36** (1.61) utilize a dual approach to gradient moves. Instead of just reducing indices contributing to the peak, they also identify "inactive" indices (those with the lowest gradient) and boost them. This simultaneously lowers the convolution maximum and increases the sequence sum (the denominator), effectively attacking both parts of the objective function.
+*   **Annealed High-Beta Weighting**: Successful programs (**Gen 30**, **Gen 34**, **Gen 36**) employ a softmax proxy for the max-convolution using an increasing $\beta$ (e.g., `beta = 30.0 + 90.0 * progress`). This allows the search to start with a broad view of the convolution landscape and gradually sharpen focus on the exact indices causing the $L_\infty$ peaks as the budget expires.
+*   **Diverse Shape-Based Seeding and Interpolation**: Initializing the search with diverse geometric priors—specifically power-law distributions, symmetric beta-like curves, and sine waves—consistently outperforms random initialization. **Gen 30** (1.60) and **Gen 32** (1.62) use these seeds at lower resolutions ($n=256$) and use `np.interp` to carry the optimized "skeleton" to higher resolutions ($n=768$).
+*   **Spectral High-Frequency Suppression**: Incorporating FFT-based mutations to specifically damp high-frequency noise (**Gen 30**, **Gen 31**, **Gen 34**) prevents the formation of "spiky" sequences. By keeping the sequence smooth in the frequency domain, the algorithm avoids creating localized convolution peaks that are difficult for point-wise stochastic mutations to resolve.
+
+## Ineffective Approaches
+
+*   **Momentum-Based Gradient Descent**: While theoretically sound, implementing momentum-based gradient descent on the softmax proxy (**Gen 35**, score 2.02; **Gen 38**, score 1.98) significantly underperformed compared to stochastic search with gradient-informed mutations. The AC objective landscape appears sufficiently non-convex that the added "inertia" of momentum likely trapped the solver in local minima or overshot narrow optimal valleys.
+*   **Heuristic Logic Errors and Numerical Instability**: **Gen 33** (score 0.0) failed due to logical errors in gradient calculation or numerical instabilities. This highlights that while complex "surgical" heuristics are powerful, they are brittle; the most successful programs (**Gen 30**) use robust, simple `numpy` operations for their gradient approximations.
+*   **Single-Sided Peak Reduction**: Programs that only focused on reducing the convolution peak without a mechanism to fill "valleys" or boost the sequence sum (**Gen 31**, score 1.64; **Gen 39**, score 1.79) were unable to reach the 1.60-1.61 threshold.
+
+## Implementation Insights
+
+*   **Scale-Invariant Evaluation Shortcut**: The **Current Best Program (Gen 30)** optimizes efficiency by using a simplified evaluation `v = 2.0 * np.max(np.convolve(seq, seq)) / n` during the search loop. Since the objective is scale-invariant, it avoids redundant `sum_a` and `sum_a**2` calculations by ensuring the sequence is normalized to a fixed mean via `_normalize_scale`.
+*   **Surgical Mutation Targeting**: The implementation of "Targeted Reduction" in **Gen 30** uses `np.argsort(grad)[-t_size:]` to pinpoint the exact sequence elements with the highest sensitivity. This "surgical" precision, combined with a decaying mutation strength $\sigma$, allows for fine-tuning the sequence at $n=768$ without disrupting the global structure.
+*   **Resolution Schedules**: The most effective schedule found is $n = 256 \to 384 \to 512 \to 768$ (**Gen 30**). Programs that start at lower resolutions (like $n=128$ in **Gen 31**) or use fewer steps often spend too much time on coarse features and not enough on the high-dimensional refinement needed for the final $1.60$ score.
+
+## Performance Analysis
+
+*   **The 1.60 Benchmark**: **Gen 30** achieved the current best value of **1.60**, representing a consistent refinement over previous generations. This performance level is reached by combining symmetry, spectral smoothing, and the dual-action gradient moves.
+*   **Stability of Multi-Resolution**: The clustering of scores between **1.61** and **1.64** across multiple programs (**Gen 31, 32, 34, 36, 37**) confirms that the multi-resolution spectral approach is the most robust framework for this problem. The minor differences in scores (0.01-0.03) are typically down to the specific weights used in the softmax gradient and the variety of initial seeds.
+*   **Impact of Complexity**: There is a diminishing return on complexity; the most complex implementations (momentum, adaptive annealing schedules in **Gen 35/38**) performed worse than the more straightforward stochastic gradient-informed search in **Gen 30**. The key to performance is the *quality* of the mutation (targeting the right indices) rather than the complexity of the update rule.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement a Skewed Resolution Time Allocation**: Currently, the budget is split equally among resolutions. Reallocate the search time to a 15%/25%/60% split for $N=256, 512, 768$, respectively. The complex $L_\infty$ landscape at $N=768$ is significantly more rugged and requires more iterations for the gradient-informed mutations to "flatten" the auto-convolution peaks than the initial "skeleton" shaping at lower resolutions.
+
+2. **Apply Local Gaussian Smoothing to Gradient Mutations**: To prevent the formation of "spiky" sequences that create new high-frequency convolution peaks, apply a local 3-point Gaussian blur (e.g., `[0.25, 0.5, 0.25]`) specifically to the indices targeted by gradient-based reduction and their immediate neighbors. This ensures that the reductions are "smooth" rather than point-wise, maintaining the spectral integrity found in high-performing programs like Gen 30.
+
+3. **Dynamic Mutation Strategy Transition**: Shift the mutation probabilities as a function of `progress`. In the early stages (low resolution/early time), prioritize "Spectral Mutations" and "Block Perturbations" to explore global shapes; in the final 30% of the budget, increase the probability of "Softmax-weighted Gradient Moves" to 90%. This transitions the algorithm from a global stochastic search to a dedicated high-resolution local optimizer when it matters most.
+
+4. **Efficiency-Ratio Informed Boosts**: Refine the "Gradient-based Boost" by targeting indices with the highest "Efficiency Ratio," defined as $1 / (\text{grad}_i + \epsilon)$. Instead of just scaling the lowest-gradient indices, use this ratio to distribute a "boost budget" across indices that increase the sequence sum (the denominator) while having the absolute minimum impact on the auto-convolution maximum (the numerator).
+
+5. **Symmetry-Breaking "Jitter" Cycles**: The search often gets trapped in local minima within the perfectly symmetric subspace. Introduce a rare mutation (e.g., 2% probability) that intentionally breaks symmetry by applying noise to only one half of the sequence, followed by a period of search, and then a "re-symmetrization" step (`seq = (seq + seq[::-1])/2`). This allows the solver to navigate through asymmetric "bridges" between different symmetric local optima.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Dual-Action Softmax Gradient Refinement**: The current best program (**Gen 30**, score 1.60) continues to outperform more recent attempts by using a dual-target gradient strategy. Instead of only reducing indices that contribute to convolution peaks, it also identifies "inactive" indices (low gradient) and boosts them. This two-pronged approach simultaneously lowers the numerator (max convolution) and maintains/increases the denominator (sequence sum), a technique missing in less successful variants like **Gen 46** (score 2.00) which focused primarily on peak reduction.
+*   **Dynamic Softmax Temperature (Beta) Annealing**: Successful programs (**Gen 30, 41, 43, 46**) utilize a softmax proxy for the $L_\infty$ norm with an annealed $\beta$ parameter (e.g., `beta = 30.0 + 90.0 * progress`). This allows the search to initially consider a broad range of convolution indices and gradually narrow its focus to the most problematic peaks as the search progresses. **Gen 30** specifically uses this to weight gradient moves, ensuring surgical precision in the final stages of the 768-length refinement.
+*   **Multi-Resolution Scaling with Skeletal Seeding**: The most effective framework involves starting at a low resolution (e.g., $n=256$) and interpolating upwards to the final length of $n=768$. **Gen 30** (1.60) and **Gen 41** (1.63) both use diverse geometric seeds (Power Law, Gaussian, Sine) to establish a "global skeleton" at low resolution, which is then refined at higher resolutions. This prevents the search from getting trapped in high-frequency local minima that plague sequences initialized directly at $n=768$.
+*   **Spectral High-Frequency Suppression**: Incorporating FFT-based mutations to specifically damp high-frequency noise (**Gen 30**, **Gen 41**, **Gen 43**) prevents the formation of "spiky" sequences. By applying low-pass filters or suppressing the upper 80% of the frequency spectrum, these programs maintain sequence smoothness, which is inherently beneficial for minimizing the autocorrelation ratio.
+
+## Ineffective Approaches
+
+*   **Momentum-Based Gradient Descent**: While theoretically appealing for navigating complex landscapes, momentum-based updates consistently underperformed. **Gen 40** (1.66) and **Gen 41** (1.63) incorporated momentum but could not match the 1.60 score of the stochastic-gradient hybrid in **Gen 30**. In some cases, like **Gen 46** (2.00), momentum likely caused the optimizer to overshoot narrow optimal regions or introduced instability in the auto-convolution objective.
+*   **Numerical Instability in Complex Approximations**: Several programs failed validation (score 0.0) due to numerical issues. **Gen 42** and **Gen 48** suffered from instabilities when using high-beta softmax or Log-Sum-Exp logic for minimax optimization. Without robust clipping or stability offsets (like subtracting the maximum before exponentiation), these mathematical proxies lead to `NaN` values or overflows in high-dimensional search spaces ($n=768$).
+*   **Hardcoding and Environment Misalignment**: **Gen 45** (0.0) failed because it hardcoded internal resolutions and deleted the `kwargs` dictionary, making it unable to adapt to the evaluation environment's requirements. This highlights that "over-optimizing" the code structure by removing flexibility can be as fatal as a poor algorithm.
+*   **Missing Dependencies**: Despite sophisticated logic, **Gen 44** and **Gen 49** failed (0.0) simply due to missing basic imports (`import numpy as np`, `import time`). This underscores that the complexity of the mutation strategy is irrelevant if the execution environment is not properly initialized.
+
+## Implementation Insights
+
+*   **Scale-Invariant Optimization Shortcuts**: The current best program (**Gen 30**) optimizes its inner loop by using a simplified evaluation: `v = 2.0 * np.max(np.convolve(seq, seq)) / n`. Because the objective is scale-invariant, the program maintains a normalized sequence mean (via `_normalize_scale`), allowing it to skip redundant sum-of-squares calculations during high-frequency stochastic iterations.
+*   **Surgical Mutation Targeting**: **Gen 30** Pinpoints indices for modification using `np.argsort(grad)[-t_size:]`. This "surgical" precision, combined with a decaying mutation strength $\sigma$ (0.15 to 0.0), allows the algorithm to fine-tune the sequence at $n=768$ without disrupting the optimized global structure inherited from lower resolutions.
+*   **Symmetry as a Constraint**: All top-performing programs (**Gen 30, 40, 41, 43, 46**) enforce or encourage sequence symmetry (`seq = (seq + seq[::-1]) / 2.0`). This effectively halves the dimensionality of the search space, making the $n=768$ optimization significantly more tractable within the 10-second budget.
+
+## Performance Analysis
+
+*   **The 1.60 Stability Point**: The current best score of **1.60** (**Gen 30**) has proven difficult to beat. Programs using refined versions of the same multi-resolution/gradient-informed strategy (**Gen 41, 43**) tend to cluster between **1.63 and 1.66**. This suggests that the specific "Dual-Action" (peak reduction + valley boosting) found in **Gen 30** is the key differentiator for breaking the 1.63 barrier.
+*   **Complexity vs. Robustness**: There is a clear trend where increasing implementation complexity (e.g., the Log-Sum-Exp logic in **Gen 47** or the momentum in **Gen 46**) leads to worse performance or total failure compared to the simpler, robust stochastic updates used in **Gen 30**.
+*   **Impact of Resolution Schedules**: Starting at $n=256$ and scaling through $384 \to 512 \to 768$ (**Gen 30**) appears more effective than starting at $n=128$ (**Gen 40, 41, 46**). Lower resolutions ($n=128$) may lose too much structural detail when interpolated up to $n=768$, whereas $n=256$ provides a sufficient "base" for the final sequence.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Skewed Resolution Time Allocation**: The current budget is split linearly among resolutions (1/3 each). Reallocate the search time to a 10%/20%/70% split for $n=256, 512, 768$, respectively. The $L_\infty$ landscape at $n=768$ is significantly more rugged and requires more iterations for the "Dual-Action" gradient-informed mutations to flatten specific convolution peaks than the initial "skeleton" shaping at lower resolutions.
+
+2. **Apply Gaussian Smoothing to Gradient Updates**: The current point-wise gradient modifications can introduce high-frequency "spikes" that create new local convolution peaks. Apply a local 3-point Gaussian blur (e.g., `[0.25, 0.5, 0.25]`) to the targeted indices or the calculated `grad` array itself before selecting mutation sites. This ensures that reductions and boosts are "smooth," maintaining the spectral integrity that allows the FFT mutations to remain effective.
+
+3. **Incorporate Efficiency-Ratio Boosting**: Refine the "Gradient-based Boost" mutation by targeting indices with the highest "Efficiency Ratio," defined as $1 / (\text{grad}_i + \epsilon)$. Instead of just scaling the lowest-gradient indices, use this ratio to distribute a "boost budget" to indices that increase the sequence sum (the denominator) while having the absolute minimum impact on the auto-convolution maximum (the numerator), thereby more effectively lowering the overall ratio.
+
+4. **Direct Peak-Contribution Targeting**: Supplement the Softmax gradient with a "Hard-Peak" mutation. Identify the specific indices $k$ where the convolution $C[k]$ is within 1% of the maximum value, and then target the pairs of sequence indices $(i, j)$ such that $i + j = k$ for reduction. This provides a more surgical alternative to the softmax proxy, which can sometimes "blur" the focus when multiple distinct peaks exist in the convolution.
+
+5. **Annealed Symmetry Enforcement**: Instead of treating symmetry as a random mutation (5% probability), implement an "annealing" schedule for symmetry. Early in the search (low resolution), allow for more asymmetric exploration to navigate between different local minima; as `progress` approaches 1.0, increase the frequency of the `(seq + seq[::-1])/2.0` operation to 100% to ensure the final sequence benefits from the search-space reduction and spectral properties of symmetric sequences.

+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+Based on the evaluation of recent programs and the current best performer, the following analysis highlights the strategies and pitfalls encountered in optimizing the autocorrelation inequality objective.
+
+### Successful Algorithmic Patterns
+
+*   **Dual-Action Softmax Gradient Refinement (Gen 30 - Score 1.60)**: This remains the top-performing strategy. It identifies two targets for mutation: reducing indices that contribute most to convolution peaks (high gradient) and boosting "inactive" indices (low gradient). This simultaneously lowers the maximum convolution (numerator) and increases the sequence mass/sum (denominator), effectively minimizing the ratio.
+*   **Structural Priors with Power-Law Seeding (Gen 58 - Score 1.61, Gen 57 - Score 1.62)**: These high-performing programs utilize power-law distributions (e.g., $(n - i)^{-p}$) for initialization. This structural prior, combined with symmetry enforcement, places the initial sequence in a region of the search space much closer to the global optimum than random or flat initialization.
+*   **Symmetry Enforcement as a Dimensionality Reduction Tool (Gen 30, 54, 58, 59)**: All programs achieving scores $\le 1.64$ enforce sequence symmetry (`seq = (seq + seq[::-1]) / 2.0`). This effectively halves the search space complexity at the target resolution of $n=768$, allowing more effective optimization within the 10-second budget.
+*   **Progressive Multi-Resolution Schedules (Gen 30, 54, 57, 58)**: Starting optimization at low resolutions (e.g., $n=128$ or $n=256$) and interpolating upwards to $n=768$ allows the algorithm to find the "global skeleton" of the sequence before refining high-frequency details. Gen 30’s specific schedule ($256 \to 384 \to 512 \to 768$) provides more incremental refinement steps than the jumps used in lower-scoring programs.
+
+### Ineffective Approaches
+
+*   **Pure Peak-Reduction Heuristics (Gen 52, 53 - Scores 1.65-1.67)**: Approaches that focus solely on "surgical peak reduction" or "sensitivity reduction" without a secondary mechanism to maintain or boost the sequence sum tend to stagnate. Without the "Dual-Action" (boost) found in Gen 30, the sequence sum often decreases alongside the peaks, keeping the overall ratio higher.
+*   **Momentum-Based and Complex Differentiable Proxies (Gen 51, 54, 55)**: While momentum and complex gradient approximations are theoretically sound, they often underperform compared to simple stochastic gradient moves. Gen 51 and 54 achieved 1.64, failing to match the 1.60 of Gen 30. In Gen 55, numerical instability in the softmax-weighted gradient calculation led to a validation failure.
+*   **High-Beta Softmax without Stability (Gen 55, 56 - Score 0.0)**: Attempting to use very high temperature (beta) parameters in the softmax function to approximate the $L_\infty$ norm (max operator) often leads to numerical overflow or `NaN` values if not managed with proper offsets or clipping. Programs like Gen 56 failed to pass validation likely due to these stability issues during the log-gradient calculation.
+
+### Implementation Insights
+
+*   **Efficient Softmax-Gradient Implementation**: Gen 30 and 59 use a differentiable proxy where weights are calculated as $w = \exp(\beta \cdot (c / \max(c) - 1))$. Subtracting the maximum from the convolution values before exponentiation is a critical stability technique that prevents floating-point overflow while maintaining the relative weighting of indices.
+*   **Scale-Invariant Evaluation Shortcuts**: The best programs (**Gen 30, 58**) utilize a normalized sequence (via `_normalize_scale`) such that the sum is constant. This allows the inner optimization loop to use a simplified objective $v = 2.0 \cdot \max(\text{conv}) / n$, significantly reducing the computational overhead per iteration by skipping redundant sum calculations.
+*   **Spectral High-Frequency Suppression (Gen 30, 51, 54, 57)**: Using FFT to damp high-frequency noise (e.g., suppressing the top 80% of frequencies) prevents the sequence from becoming "spiky." Smoothness in the spatial domain is a key characteristic of sequences that minimize the peak-to-sum autocorrelation ratio.
+
+### Performance Analysis
+
+*   **The 1.60 Barrier**: The score of **1.60 (Gen 30)** has remained the benchmark for several generations. The closest recent competitor is **Gen 58 (Score 1.61)**, which used a "surgical efficiency-gap" mutation. The difference suggests that Gen 30's specific "Dual-Action" gradient move (combining reduction and boost) is more effective than the efficiency-gap approach.
+*   **Clustering of Heuristic Optimizers**: Most programs employing standard multi-resolution and gradient-proxy techniques (Gens 51, 54, 59) cluster around a score of **1.64**. Moving below this point consistently requires either structural priors (Power Law) or dual-target gradient strategies.
+*   **Validation Failures in Advanced Log-Gradients**: There is a clear trend where increasing the complexity of the gradient approximation (e.g., Gen 55 and 56) increases the risk of program failure (Score 0.0). Simpler stochastic updates with beta-annealing (Gen 30) provide a better balance between optimization power and execution stability.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Skewed Resolution Time Allocation**: Reallocate the 10-second search budget from a linear split to a 10%/20%/70% distribution for resolutions $n=256, 512, 768$, respectively. The objective landscape at $n=768$ is significantly more rugged and requires the majority of the iterations to allow the "Dual-Action" gradient moves to surgically flatten the numerous local convolution peaks that emerge during interpolation.
+
+2. **Apply Local Smoothing to Gradient Updates**: Instead of applying point-wise modifications to the sequence, apply a 3-point Gaussian blur (kernel `[0.25, 0.5, 0.25]`) to the calculated `grad` array before selecting the indices for reduction or boost. This ensures that the mutations are spatially smooth, preventing the introduction of high-frequency "spikes" that immediately create new secondary convolution peaks, thereby maintaining the spectral integrity of the sequence.
+
+3. **Direct Peak-Contribution Targeting (Hard-Peak Mutation)**: Supplement the Softmax-weighted gradient with a "surgical" mutation that identifies the exact index $k$ of the maximum convolution value and targets the specific sequence indices $(i, j)$ where $i+j=k$ and the product $seq[i] \cdot seq[j]$ is largest. By reducing these specific contributors to the global maximum, the algorithm can bypass the "blurring" effect of the softmax proxy when multiple peaks have similar magnitudes.
+
+4. **Annealed Symmetry Enforcement**: Transition symmetry from a random mutation to a deterministic constraint as the search nears completion. If `progress > 0.75`, enforce `seq = (seq + seq[::-1]) / 2.0` at the end of every iteration; this effectively halves the search space dimensionality during the most critical refinement phase, focusing all remaining computational power on the $n/2$ degrees of freedom known to contain high-performing solutions.
+
+5. **Gradient-Based Efficiency-Ratio Boosting**: Refine the "Boost" mutation by targeting indices with the highest "Efficiency Ratio," defined as $1 / (grad_i + \epsilon)$. Instead of scaling the lowest-gradient indices uniformly, distribute a "boost budget" proportionally to this ratio to prioritize increasing indices that contribute most to the sequence sum (the denominator) while having the absolute minimum impact on the convolution maximum (the numerator).

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+- **Multiplicative "Peak Pressure" Optimization (Gen 61):** The most significant breakthrough (Score -2.00) involved moving away from simple additive gradient moves to a multiplicative update rule based on "peak pressure." This technique identifies specific indices contributing to convolution maxima and scales them down proportionally, which is more stable and effective at navigating the $L_\infty$ landscape than additive noise or standard gradient descent.
+- **Power-Law Initialization with Progressive Symmetry (Gen 65, 62):** Starting with a structural prior like a power-law distribution ($(n - i)^{-p}$) or symmetric power-law significantly outperforms random initialization. Gen 65 achieved a high score of -1.95 by combining this seeding with progressive symmetry enforcement, which reduces the search space dimensionality precisely when the algorithm transitions from global shape discovery to local refinement.
+- **Dual-Action Gradient Refinement (Current Best - Gen 30):** This strategy remains a core pillar of success. By identifying two targets—reducing high-gradient indices (peak contributors) and boosting low-gradient "inactive" indices—the algorithm simultaneously lowers the numerator (max convolution) and maintains the denominator (sequence sum). This "push-pull" dynamic prevents the sequence from shrinking into a trivial zero-vector while minimizing the ratio.
+- **Annealed Resolution Scaling (Gen 61, 65, 67):** Successful programs consistently use a multi-resolution schedule (starting as low as $n=128$ and scaling up to $n=768$). This allows the search to settle into a "low-frequency" global optimum before fine-tuning high-frequency components at the target length.
+
+## Ineffective Approaches
+
+- **Library Import Errors in Complex Refiners (Gen 60, 63, 69):** Multiple sophisticated programs (Multiplicative Gradient, Surgical Log-Gradient) failed completely (Score 0.0) due to a recurring implementation oversight: missing `import numpy` or `import time` within the specific scope of the evolution block. This suggests that as optimization logic becomes more complex, maintaining basic environmental boilerplate is a common failure point.
+- **Pure Peak-Reduction without Sum-Maintenance (Gen 52, 53):** Approaches that focus exclusively on reducing the convolution peaks without a mechanism to increase or stabilize the sequence sum tend to plateau. Without the "Dual-Action" or "Efficiency-Gap" boosting components seen in Gen 30 and Gen 64, the ratio often stagnates because the denominator decreases at a similar rate to the numerator.
+- **High-Complexity Gradient Proxies without Stability (Gen 55, 56):** Attempting to use a very high-beta softmax to approximate the max operator often results in numerical overflow or `NaN` values. Programs that achieved high scores (Gen 30, 61) used a stabilized log-sum-exp approach or subtracted the maximum value before exponentiation (`w = exp(beta * (c/max_c - 1))`) to maintain numerical sanity.
+
+## Implementation Insights
+
+- **Scale-Invariant Evaluation Shortcuts:** The current best program (Gen 30) and Gen 61 optimize efficiency by using a normalized sequence (`_normalize_scale`) where the sum is fixed. This allows the inner loop to calculate the objective using only the convolution maximum (`v = 2.0 * max_c / n`), drastically reducing the computational cost per iteration compared to full ratio calculations.
+- **Spectral Mutation for Global Smoothing (Gen 68, 67, 30):** Using FFT to suppress high-frequency noise (e.g., damping the top 80% of frequencies) acts as a powerful regularizer. It ensures the sequence remains "smooth," which is a known characteristic of low-autocorrelation sequences. This prevents the gradient moves from creating "spiky" sequences that are trapped in poor local minima.
+- **Symmetry as a Complexity Filter:** High-performing programs (Gen 61, 65, 62) often treat symmetry not just as a mutation, but as a constraint. By enforcing `seq = (seq + seq[::-1]) / 2.0` throughout the later stages of optimization, they effectively double the search budget by halving the number of free variables to be optimized.
+
+## Performance Analysis
+
+- **Breaking the 1.60 Benchmark:** For several generations, the best performance was stuck at **1.60 (Gen 30)**. The jump to **2.00 (Gen 61)** and **1.95 (Gen 65)** indicates that shifting from additive gradient proxies to multiplicative "peak pressure" updates and better structural seeding (Power-Law) is significantly more effective than increasing the complexity of the gradient approximation itself.
+- **Clustering of Pseudo-Gradient Methods:** Most programs using standard log-gradient descent or efficiency-gap mutations (Gen 64, 66, 67, 68) cluster tightly around the **1.61 to 1.65** range. This suggests a performance ceiling for additive local search methods that only "peak-pressure" or advanced seeding can break.
+- **Impact of Multi-Resolution Schedules:** Programs that start at a lower base resolution (e.g., $n=128$ in Gen 61 and 65) consistently outperform those starting at higher resolutions (e.g., $n=256$ in Gen 60 and 63). The extra steps of refinement allow for a more robust "skeletal" structure to form before the final $n=768$ optimization.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Multiplicative "Peak Pressure" Updates**: Replace the standard additive/multiplicative gradient moves with a rule that specifically targets the convolution maxima. For the index $k$ where the convolution $C = \text{seq} * \text{seq}$ is maximized, identify all pairs $(i, j)$ such that $i+j=k$. Apply a reduction factor to $\text{seq}[i]$ and $\text{seq}[j]$ proportional to the product $\text{seq}[i] \cdot \text{seq}[j]$, which stabilizes the $L_\infty$ landscape more effectively than uniform gradient steps (as seen in the Gen 61 breakthrough, Score -2.00).
+
+2. **Transition to Enforced Symmetry Constraints**: Move symmetry from a random mutation to a deterministic constraint in the latter stages of the search. If `progress > 0.70`, enforce `seq = (seq + seq[::-1]) / 2.0` at the end of every iteration. This halves the search space dimensionality during the refinement phase, allowing the gradient descent to focus computational budget on the $n/2$ degrees of freedom that characterize optimal sequences.
+
+3. **Prioritize Power-Law Seeding**: Refine the `_seed_sequence` function to more heavily weight the Power-Law distribution $(n - i)^{-p}$ with $p \in [0.45, 0.55]$. Evidence from Gen 65 suggests that this specific "skeletal" structure provides a superior global starting point compared to Gaussian or Sine waves, as it naturally balances the sequence sum (denominator) against the distribution of convolution peaks (numerator).
+
+4. **Expand Multi-Resolution Schedule starting at $n=128$**: Introduce a lower initial resolution (e.g., $n=128$) before moving to 256, 512, and 768. Finding the global "envelope" of the sequence is significantly faster and more robust at low resolutions; the resulting structure can then be interpolated to higher resolutions for surgical refinement of high-frequency peaks.
+
+5. **High-Beta Softmax with Log-Sum-Exp Stability**: To better approximate the $L_\infty$ (max) operator, increase the softmax temperature $\beta$ progressively up to 200-500. To prevent numerical overflow at these levels, always use the stabilized form `w = exp(beta * (c/max_c - 1.0))`. This ensures the gradient moves are concentrated only on the most critical peaks, preventing the "blurring" effect that occurs with lower beta values.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+- **Multi-Resolution Search Ladder (Gens 71, 72, 74, 75, 77, 78, 79):** The most consistent success factor is scaling the sequence length progressively (e.g., 128 $\to$ 256 $\to$ 512 $\to$ 768). This allows the algorithm to discover the "skeletal" global structure at low resolutions before fine-tuning high-frequency coefficients at the final target length. **Gen 72 (Current Best: 1.60)** and **Gen 77 (1.61)** utilized four distinct resolution stages with specific time-share allocations.
+- **Sharpened Softmax-Weighted Gradients (Gen 72, 77):** Using a temperature-controlled softmax ($w = \exp(\beta \cdot (c/max\_c - 1.0))$) to identify indices contributing most to the convolution peaks has proven superior to simple gradient proxies. **Gen 72** successfully used an annealed $\beta$ (increasing from 30.0 to 200.0) to focus the optimization on the most critical peak contributors as the search progressed.
+- **Multiplicative "Peak Pressure" and Efficiency-Gap Updates (Gen 71, 72, 79):** Instead of additive noise, the best-performing programs utilize multiplicative scaling (e.g., `seq[idx] *= (1.0 - sigma)`) to reduce mass at peak-contributing indices. This approach, seen in **Gen 71 (1.67)** and **Gen 72 (1.60)**, is more stable for the non-negative constraint and more effective at navigating the $L_\infty$ landscape of the convolution maximum.
+- **Power-Law Seeding for Structural Priors (Gen 71, 72, 73, 78):** Initializing sequences with power-law distributions ($(n-i)^{-p}$) or symmetric variations provides a high-quality starting point. **Gen 72** specifically included diverse seeds (Asymmetric/Symmetric power laws, Sinusoids, and Gaussians), which prevented the search from getting trapped in the poor local minima associated with uniform or random starts.
+
+## Ineffective Approaches
+
+- **Scoping and Import Errors in Complex Logic (Gen 70, 76):** High-complexity programs often fail due to basic environmental errors. **Gen 70** and **Gen 76** achieved scores of 0.0 because they lacked essential library imports (`numpy`, `time`) or crashed during complex mutation logic. This highlights a recurring failure point where algorithmic sophistication is negated by implementation oversights.
+- **Single-Resolution Optimization (Historical Comparison):** Programs that attempt to optimize at $n=768$ from the start consistently perform worse or take longer to converge than those using the 128-768 ladder. Without the multi-resolution smoothing, the gradient-based moves often become trapped by high-frequency "noise" in the convolution output.
+- **Fixed-Beta Softmax Proxies (Gen 73, 78):** Using a static or low-value $\beta$ for softmax gradients leads to sub-optimal results (e.g., **Gen 73's score of 1.96**). Without annealing the precision of the max-operator approximation, the algorithm fails to distinguish between the primary convolution peak and secondary "shoulder" peaks, leading to inefficient mass distribution.
+
+## Implementation Insights
+
+- **Scale-Invariant Objective Shortcuts (Gen 72):** The current best program (**Gen 72**) and several high-performers (Gen 77, 79) utilize a `_normalize_scale` function that forces the sequence sum to equal $n$. This effectively transforms the objective into $2.0 \cdot \max(C) / n$. By fixing the denominator, the mutation operators can focus exclusively on reducing the convolution maximum, which significantly stabilizes the search.
+- **Symmetry as an Annealed Constraint (Gen 72, 77, 79):** Successful programs treat symmetry as a "soft" constraint that hardens over time. **Gen 72** enforces symmetry with 40% probability initially, but increases this during the final resolution stages. This allows for the discovery of asymmetric global shapes that are then refined into the highly symmetric structures known to be optimal for AC problems.
+- **Spectral Regularization (Gen 72, 75, 79):** Using FFT to damp high-frequency components (Spectral Mutation) acts as a powerful regularizer. **Gen 72** daps the top 80% of frequencies during specific mutation steps, ensuring the sequence remains smooth and avoiding the "spiky" distributions that characterize poor local minima in the autocorrelation space.
+- **Time-Budgeted Multi-Resolution (Gen 72):** Assigning explicit time shares to different resolutions (e.g., 10% for $n=128$, 50% for $n=512$) ensures that the algorithm does not spend too much time on low-impact early iterations or arrive at the target resolution ($n=768$) with insufficient time for local refinement.
+
+## Performance Analysis
+
+- **The 1.60 Convergence Barrier:** Performance across the most successful recent programs (Gens 72, 74, 77, 79) has clustered tightly between **1.60 and 1.62**. This suggests that while multi-resolution and softmax gradients are highly effective, the current suite of mutation operators may be approaching a local plateau.
+- **Impact of Mutation Diversity:** **Gen 72 (1.60)** utilized seven distinct mutation types (Block, Scattered, Softmax-Gradient, Peak Pressure, Efficiency Boost, Spectral, and Symmetry Mirror). Programs with fewer operators, like **Gen 75 (1.69)**, typically fail to achieve the same level of refinement.
+- **Efficiency of Multiplicative Moves:** Programs using multiplicative "Peak Pressure" (Gen 72, 78, 79) generally reach values below 1.70 much faster than those relying purely on additive Gaussian noise or simple gradient descent, confirming that proportional reduction of peak contributors is the most efficient way to minimize the ratio.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Annealed High-Beta Softmax with Log-Sum-Exp Stability**: Current programs use $\beta$ up to 200, but to truly break the 1.60 barrier, the softmax needs to more closely approximate the hard $L_\infty$ maximum. Increase the $\beta$ range to 500 in the final resolution stage ($n=768$) and ensure numerical stability by using the identity $w = \exp(\beta \cdot (C - \max(C)))$; this forces the "Softmax Gradient" to only update the indices responsible for the single highest peak, preventing the "blurring" of mass across sub-optimal peaks.
+
+2. **Adaptive Mutation Weighting (Exploration to Exploitation)**: Transition mutation probabilities dynamically as the search progresses through the resolution ladder. Use higher weights for "Spectral Mutation" and "Block Perturbation" during the $n=128$ and $n=256$ stages to discover the global "envelope," then shift weight toward "Sharpened Softmax Gradient" and "Peak Pressure" (up to 80% combined probability) during the final $n=768$ stage for surgical precision in minimizing the convolution maximum.
+
+3. **Deterministic Symmetry Hardening**: While allowing asymmetry is useful for early exploration, the optimal sequences for this problem are known to be highly symmetric. In the final resolution stage ($n=768$), after `progress > 0.85`, move from a 40% chance of symmetry to a 100% deterministic constraint (`seq = (seq + seq[::-1]) / 2.0`) at the end of every iteration; this effectively halves the search space and concentrates the remaining time-budget on the most relevant degrees of freedom.
+
+4. **Windowed Power-Law Seeding**: The power-law distribution $(n-i)^{-p}$ is a successful prior but often suffers from high-frequency noise at the sequence edges ($i \approx 0$). Refine the `_seed_sequence` function by applying a Tukey or Hann window to the power-law seeds to "taper" the edges before the search begins; this provides a smoother initial convolution profile and prevents the gradient descent from wasting iterations correcting edge artifacts.
+
+5. **Coupled "Peak-to-Gap" Mass Transfer**: Instead of independent "Peak Pressure" and "Efficiency Boost" moves, implement a coupled mutation that identifies the indices $(i, j)$ contributing to the max convolution $C[k]$ and the indices $m$ where $C[m]$ is lowest. Directly subtract a small amount $\delta$ from $seq[i], seq[j]$ and add it to $seq[m]$; this "water-filling" approach maintains the sequence sum more effectively than independent multiplicative moves and directly addresses the efficiency gap.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+- **Multi-Resolution Resolution Ladders with Precise Time Allocation:** The most successful programs consistently employ a resolution-climbing strategy (e.g., $128 \to 256 \to 512 \to 768$). The current best program (**Gen 72**, Score 1.60) and high-performers like **Gen 81** and **Gen 87** (both 1.61) allocate specific time shares to each resolution. This allows the search to settle on a global "envelope" at low resolutions before refining high-frequency details at $n=768$.
+- **High-Beta Softmax Gradient Weighting:** Using a softmax function with a high or annealed $\beta$ temperature (e.g., $\beta$ increasing from 30 to 200 in **Gen 72**) to weight gradient updates is critical. This technique identifies the specific indices that contribute most to the convolution peak. **Gen 87 (1.61)** and **Gen 89 (1.62)** successfully used similar "high-beta" or "sensitivity-based" proxies to perform targeted mass redistribution.
+- **Multiplicative "Peak Pressure" Mutations:** Instead of additive Gaussian noise, successful programs use multiplicative scaling to reduce the value of coefficients contributing to convolution peaks. **Gen 72** uses `seq[idx] *= (1.0 - sigma)`, and **Gen 86 (2.00)** utilized "peak-pressure reductions." This approach is inherently more stable for maintaining non-negativity and is more effective at dampening the $L_\infty$ norm of the convolution.
+- **Power-Law and Structural Seeding:** Initializing the search with power-law distributions ($(n-i)^{-p}$) provides a significant head start over random initialization. **Gen 81 (1.61)** and **Gen 89 (1.62)** specifically credited "power-law seeding" for providing flatter initial convolutions, which are then refined by gradient moves.
+
+## Ineffective Approaches
+
+- **Omission of Essential Library Imports:** A catastrophic failure pattern in recent generations (Gens 80, 84, 85, 88) is the failure to include `import numpy` or `import time` within the scoped execution block. Despite featuring sophisticated logic like Log-Sum-Exp or Mirror Descent, these programs achieved a score of 0.0 because they failed validation tests immediately.
+- **Fixed-Resolution Optimization at High $n$:** Programs that attempt to optimize at $n=768$ without a laddering approach (or those that fail the laddering transition like **Gen 82**) often fail. **Gen 82** failed validation likely because it returned a sequence length ($n=768$) that did not match the specific requirements of the evaluation call, highlighting the need for flexible resolution handling.
+- **Numerical Instability in Gradient Proxies:** Approaches like **Gen 83** (Mirror Descent) and **Gen 84** (Natural Gradient) failed due to numerical instabilities. This often occurs when calculating exponentials for softmax or log-sum-exp gradients without proper normalization or "Log-Sum-Exp tricks" to prevent overflow at high $\beta$ values.
+
+## Implementation Insights
+
+- **Scale-Invariant Normalization:** The current best program (**Gen 72**) uses a `_normalize_scale` function that forces $\sum A_i = n$. By fixing the sum, the algorithm simplifies the objective $2n \cdot \max(C) / (\sum A)^2$ to $2 \cdot \max(C) / n$. This turns a complex ratio optimization into a simpler peak-minimization task, which stabilizes the gradient updates.
+- **Symmetry as a Hardening Constraint:** High-performing programs (**Gen 72, 81, 87**) treat symmetry as a flexible constraint. **Gen 72** enforces symmetry with a 40% probability early on, while **Gen 86** used "late-stage symmetry hardening." This allows the search to explore asymmetric spaces early to find better global structures before snapping to the symmetric shapes that are known to be optimal for the AC problem.
+- **Spectral Regularization (FFT Damping):** **Gen 72, 81,** and **87** all incorporate spectral mutations or FFT-based smoothing. By damping the top 80% of frequencies (as seen in **Gen 72**), the algorithm prevents the sequence from becoming too "spiky," which typically leads to high autocorrelation peaks.
+
+## Performance Analysis
+
+- **The 1.60 Efficiency Plateau:** There is a clear performance cluster between 1.60 and 1.62 (Gens 72, 81, 87, 89). This suggests that the combination of multi-resolution ladders and softmax-weighted gradients is highly effective but may be hitting a local optimum. The difference between **Gen 72 (1.60)** and **Gen 81 (1.61)** appears to be the breadth of the mutation suite and the specific annealing schedule.
+- **Sensitivity of Mutation Diversity:** **Gen 72** utilizes seven distinct mutation types (Block, Scattered, Softmax-Gradient, Peak Pressure, Efficiency Boost, Spectral, and Symmetry Mirror). Programs with fewer or less specialized operators (like **Gen 86's** more limited set) tend to converge to higher (worse) values, such as 2.00.
+- **Impact of Time-Budgeting:** The use of `time_shares` in **Gen 72** (e.g., 10% for $n=128$, 50% for $n=512$) is a crucial differentiator. It ensures that the algorithm spends enough time on the final refinement stage at $n=768$ without wasting the entire budget on low-resolution stages that only need to find a rough "skeleton."
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Push Softmax β to "Hard-Max" Limits with Numerical Safeguards**: While the current program uses $\beta$ up to 200, breaking the 1.60 plateau likely requires isolating the exact indices responsible for the peak. Increase the maximum $\beta$ to 500 during the final $n=768$ stage and ensure stability using the identity $w = \exp(\beta \cdot (C - \max(C)))$; this "Super-Sharpened Gradient" will prevent the blurring of mass and allow for surgical dampening of the $L_\infty$ norm.
+
+2. **Transition from Exploration to Exploitation via Adaptive Mutation Weights**: The current static mutation probabilities should be replaced with a schedule that shifts focus as the search progresses. Allocate high weights to "Spectral Mutation" and "Block Perturbation" during the $n=128$ and $n=256$ stages to define the global structure, then transition to over 80% "Softmax Gradient" and "Peak Pressure" moves during the $n=768$ stage to refine the sequence with high precision.
+
+3. **Enforce Deterministic Symmetry Hardening in the Final Phase**: While early-stage asymmetry allows the search to navigate around local optima, the optimal solutions for the Autocorrelation (AC) problem are historically symmetric. In the final resolution stage ($n=768$), especially after `progress > 0.85`, the algorithm should switch from a 40% probability to a 100% deterministic symmetry constraint (`seq = (seq + seq[::-1]) / 2.0`) to effectively halve the search dimensionality and concentrate resources on the most promising region.
+
+4. **Implement Coupled "Peak-to-Gap" Mass Migration**: Instead of independent "Peak Pressure" (reduction) and "Efficiency Boost" (addition) moves, implement a coupled mutation that identifies the indices $(i, j)$ contributing to the max convolution $C[k]$ and the indices $m$ where $C[m]$ is lowest. Directly subtract a small amount $\delta$ from $seq[i], seq[j]$ and add it to $seq[m]$; this "water-filling" approach maintains the sequence sum more effectively and directly addresses the efficiency gap.
+
+5. **Frequency-Selective Spectral Damping**: Refine the spectral mutation to be more targeted than a blanket 80% damping. Analyze the FFT of the sequence and specifically damp the frequency bands that show the highest power relative to the "power-law" ideal; this preserves the beneficial global "envelope" discovered at low resolutions while suppressing the high-frequency "jitter" often introduced by the stochastic gradient moves.

+  "meta_scratch_pad": "The following analysis extracts optimization insights from the evaluation of programs targeting the Autocorrelation (AC) inequality, building upon previous global observations and focusing on the current best-performing implementation (**Gen 190/188**).\n\n### Successful Algorithmic Patterns\n\n*   **Annealed High-Beta Surgical Gradient:** The most successful pattern (achieving 1.60 in **Gen 190**) involves a \"Surgical Mirror Descent\" operator. This method uses a stable softmax-weighted gradient where $\\beta$ is annealed from 30 to 200 over the run. By convolving the weighted error (representing convolution peaks) with the reversed sequence, the algorithm calculates a precise sensitivity map, allowing it to target only the coefficients that contribute to the $L_\\infty$ norm.\n*   **Mass-Preserving Migration & Log-Gradients:** Programs achieving scores of 1.60\u20131.62 (**Gen 190, 194, 198**) utilize \"Peak-to-Valley\" migration. Instead of purely reductive moves, these algorithms shift mass from indices causing convolution peaks to those causing valleys. **Gen 198** specifically utilized log-gradients of the convolution to refine this migration, which helps flatten the convolution profile while maintaining the sequence sum.\n*   **Progressive Resolution Scaling with Symmetry Hardening:** All top-performing programs (**Gen 190, 192, 194, 198**) utilize a multi-resolution ladder (scaling from 128 to 768). The strategy involves spending the final 50% of the time budget at $n=768$. **Gen 190** also implements \"Symmetry Hardening,\" where symmetry is enforced more strictly (increasing from 40% to 100% probability) as the resolution increases, preventing the search from being trapped in suboptimal asymmetric local minima.\n*   **Power-Law and Gaussian Seeding:** Starting with a theoretically grounded shape (like $x^{-0.5}$ in **Gen 190** and **Gen 192**) provides a \"flat\" initial convolution profile. This allows the subsequent gradient-based \"nanosurgery\" to focus on micro-optimizations rather than trying to discover the global envelope from a random state.\n\n### Ineffective Approaches\n\n*   **Missing Core Dependencies:** A recurring failure mode in the current generation (**Gen 193, 195, 199**) was the omission of `import numpy` or `import time` within the local scope or global program. Despite having sophisticated logic (e.g., \"Symmetric Nanosurgery\"), these programs failed validation immediately with a score of 0.0.\n*   **Numerical Instability in High-Beta Weighting:** While high-beta softmax is effective, implementations that fail to use the \"stable softmax trick\" ($c/max\\_c - 1.0$) likely suffer from floating-point overflows. **Gen 197** likely failed validation or convergence due to such instability in its \"Peak Isolation\" logic when calculating exponential weights.\n*   **Over-reliance on Global Spectral Mutations:** While spectral damping (FFT-based) helps maintain a smooth sequence, programs that relied too heavily on it without index-specific surgical moves (implied by the feedback for **Gen 189** and observed in the lower performance of **Gen 194** at 1.62 vs. 1.60) failed to reach the best-known values. Global moves at high resolution disrupt the delicate balance of the convolution.\n\n### Implementation Insights\n\n*   **Multiplicative Multi-Index Updates:** The current best program (**Gen 190**) uses multiplicative updates: `seq[target_idx] *= (1.0 - sigma * scale)`. This is superior to additive updates for this task because it naturally maintains non-negativity and scales the perturbation relative to the coefficient magnitude, which is more effective for a scale-invariant objective.\n*   **Symmetry-Aware Perturbation:** In **Gen 190**, perturbations are applied symmetrically if the sequence is already symmetric (`if was_symmetric: seq[n - bstart - blen : n - bstart] += delta[::-1]`). This preserves the structural properties of the sequence throughout the mutation process, drastically reducing the search space.\n*   **Stable Gradient Attribution:** The \"nanosurgery\" effective in **Gen 190** and **Gen 198** is powered by `grad = np.convolve(w, seq[::-1], mode='full')[n-1 : 2*n-1]`. This specific implementation of the gradient calculation correctly identifies how each $A_i$ influences the convolution peaks $C_k$, which is the crucial differentiator for reaching the 1.60 threshold.\n\n### Performance Analysis\n\n*   **The 1.60 Barrier:** **Gen 190** (and its predecessor **Gen 188**) represents the current performance ceiling. Achieving this score requires the precise integration of power-law initialization, resolution laddering, and annealed surgical mirror descent.\n*   **Resolution and Efficiency:** There is a clear correlation between the time spent at $n=768$ and the final score. Programs like **Gen 192** (1.64) and **Gen 194/198** (1.62) used similar techniques but achieved slightly worse results than **Gen 190** (1.60), likely due to less efficient time allocation between the \"global search\" (low resolution) and \"fine refinement\" (high resolution) phases.\n*   **Success Rate of Sophisticated Heuristics:** The data shows a high \"failure-to-execute\" rate for complex programs. While the \"Surgical Mirror Descent\" approach is the most successful, it is also the most prone to implementation errors (missing imports, numerical overflow), as seen in the 0.0 scores of **Gen 191, 193, 195, 196, 197, and 199**. Successful programs are those that balance sophisticated gradient heuristics with robust, vectorized NumPy implementations.",
+  "meta_recommendations": "1. **Implement Explicit Half-Length Search for the $n=768$ Phase**: Since symmetry is nearly 100% enforced in the final stages of the best program, explicitly reduce the search space by optimizing only the first $n/2$ elements and reflecting them to form the full sequence. This effectively doubles the iteration speed at the most computationally expensive resolution, allowing for deeper refinement of the symmetric profile which has consistently yielded the 1.60 score.\n\n2. **Execute Coupled \"Peak-to-Valley\" Mass Migration**: Replace the independent multiplicative updates (currently $m\\_type < 0.50$ and $m\\_type < 0.80$) with a single operator that moves mass directly from indices with high gradient sensitivity to those with low sensitivity. By subtracting a small delta from \"peak-contributing\" indices and adding it to \"valley-filling\" indices, you maintain a constant $\\sum A$ and prevent the optimizer from drifting into regions of the search space that require global re-normalization.\n\n3. **Escalate to Ultra-High Beta (1000+) with Numerical Stability**: Extend the softmax $\\beta$ annealing range from the current max of 200 up to 1000 or higher during the final 20% of the budget. To prevent overflow, strictly use the `np.exp(beta * (c / max_c - 1.0))` formulation; this \"surgical\" precision isolates only the absolute maximum of the convolution, ensuring that late-stage mutations target the $L_\\infty$ norm exclusively without introducing collateral noise in the rest of the sequence.\n\n4. **Apply Gaussian Smoothing to Gradient Updates**: Before applying the calculated gradient to the sequence, convolve the update vector with a narrow Gaussian kernel ($\\sigma \\approx 1.0 - 2.0$). This prevents \"nanosurgery\" from creating high-frequency \"jaggedness\" or local spikes in the sequence envelope, which often lead to new, secondary convolution peaks that stall convergence near the 1.60 barrier.\n\n5. **Transition to Patience-Based Adaptive Resolution Scaling**: Replace the fixed `time_shares` ladder with a trigger that upscales the resolution only when the objective has failed to improve by a small epsilon (e.g., $10^{-5}$) for a fixed number of iterations (patience). This ensures that the macro-envelope of the sequence is fully optimized at lower resolutions (128, 256) before committing the majority of the time budget to the high-cost $n=768$ refinement.",
+  "meta_recommendations_history": [
+    "Based on the success of Gen 9 and the identified algorithmic patterns, here are five actionable recommendations for future program mutations:\n\n1.  **Distributed Peak-Reduction and Compensation**: Enhance the current \"Peak Reduction\" move by targeting not just the single highest-contributing index, but a neighborhood of indices contributing to the top $k$ peaks of the convolution. Simultaneously, implement a \"Compensation\" step that slightly increases the values of indices that contribute the least to the convolution peaks; this raises the total sum ($\\sum s$) without increasing $\\max(\\text{conv}(s, s))$, directly improving the objective ratio.\n\n2.  **Frequency-Domain (FFT) Mutations**: Since low-frequency structures (sinusoids, Gaussians) are more effective than high-frequency noise, implement mutations in the spectral domain. By applying small perturbations to the low-frequency components of the sequence's FFT and then transforming back, the search can explore smooth variations that preserve the global shape and \"energy\" distribution, which is less likely to create the sharp peaks that degrade the objective score.\n\n3.  **Active Symmetry Enforcement**: While the current program uses symmetry in seeds, it does not maintain it during the mutation phase. Implement an \"Enforce Symmetry\" mutation that replaces a sequence with its average and its reverse ($s_{new} = (s + \\text{reverse}(s)) / 2$). Given the self-convolution nature of the task, symmetric sequences often produce more predictable convolution profiles, making the search for a global minimum more stable and constrained.\n\n4.  **Convergence-Triggered Resolution Scaling**: Instead of fixed time-slices for each resolution (128, 256, 512, 768), implement an adaptive schedule that triggers upsampling only when the objective value fails to improve by a certain epsilon over a set number of iterations. This ensures the program spends more time fine-tuning at the highest resolution ($n=768$), where the search space is largest and most sensitive, rather than being forced to move on by a rigid clock.\n\n5.  **Targeted Coordinate Descent for Fine-Tuning**: In the final resolution phase, replace random scattered perturbations with a targeted coordinate descent on the \"hotspots.\" Identify the indices $i$ that contribute to the convolution values within 95% of the maximum peak; perform small, deterministic line-searches (gradient-free) on these specific values to minimize the peak. This transition from stochastic search to local optimization is crucial for breaking the 1.63 plateau.",
+    "Based on the success of the Current Best Program (Gen 9) and the analysis of previous iterations, here are five actionable recommendations for future program mutations:\n\n1.  **Top-K Peak Targeting and Denominator Boosting**: Enhance the \"Peak Reduction Move\" by identifying the top $k$ indices in the convolution that are within 5% of the maximum peak. Instead of reducing just one index, apply a weighted reduction to the indices contributing to all these high peaks, while simultaneously identifying \"inactive\" indices (those contributing least to the convolution sum) and slightly increasing their values to boost the $(\\sum a)^2$ denominator without raising the numerator.\n\n2.  **Spectral-Domain (FFT) Mutations for Smoothness**: Since low-frequency structures (Gaussians, sines) are more effective than high-frequency noise, implement mutations in the frequency domain using `np.fft.rfft`. Perturb the magnitude of low-frequency components while keeping high-frequency components attenuated; this ensures the sequence remains \"smooth\" during mutations, which is critical for preventing the sharp peaks in the auto-convolution that degrade the objective.\n\n3.  **Adaptive \"Patience-Based\" Resolution Scaling**: Replace the fixed time-slices for resolutions (128, 256, 512, 768) with an adaptive schedule. Implement a \"stagnation counter\" that triggers an upsample via `np.interp` only after the objective value fails to improve by a threshold ($1e-5$) for 50 consecutive iterations, ensuring the search spends minimal time on low-res global shaping and maximizes time on high-res local refinement.\n\n4.  **Symmetry-Preserving Local Search**: Incorporate a mutation that explicitly enforces symmetry ($s = (s + \\text{reverse}(s)) / 2$) every few iterations, as the auto-convolution of a symmetric sequence is mathematically more stable. Combine this with a targeted local search that focuses on the central indices of the sequence, as the auto-convolution peak $p$ frequently occurs near $n$ in symmetric-like distributions.\n\n5.  **Softmax-Weighted Sensitivity Dampening**: Improve upon the discrete \"Peak Reduction\" by calculating a sensitivity vector $V$ where each $V[i]$ is the sum of contributions to the convolution peaks, weighted by a softmax of the convolution values. Use this vector to apply a proportional dampening factor to the sequence ($s_{new} = s \\cdot (1 - \\sigma \\cdot V)$), allowing the program to perform \"soft\" global cooling of all potential peaks simultaneously rather than jumping between individual indices.",
+    "1. **Annealed Temperature for Sensitivity Weighting**: The current best program uses a fixed multiplier of `40.0` in the exponential weight calculation $w = \\exp(40.0 \\cdot (c / \\max(c) - 1.0))$. Implement a dynamic temperature that scales with search progress, such as $T = 20.0 + 80.0 \\cdot \\text{progress}$. A lower temperature early on allows the sensitivity gradient to consider broader regions of the sequence, while a higher temperature in the final stages makes mutations extremely surgical, focusing only on the absolute highest peaks.\n\n2. **Skewed Time Allocation for High-Resolution Refinement**: While the multi-resolution approach is successful, the current budget splits time equally (33% each) between $N=256, 512, 768$. Reallocate the budget to a 15%/25%/60% split. The complex $L_\\infty$ landscape at $N=768$ requires significantly more iterations for the sensitivity-based moves to \"flatten\" the auto-convolution than the initial \"skeleton\" shaping at $N=256$.\n\n3. **Symmetry-Breaking and Re-Symmetrization Cycles**: The search often gets trapped in local minima within the symmetric subspace. Introduce a \"jitter\" mutation that intentionally breaks symmetry (e.g., `seq[:n//2] += noise`) with a small probability, followed by a period of search, and then a \"re-symmetrization\" step (`seq = (seq + seq[::-1])/2`). This allows the algorithm to explore asymmetric \"paths\" between different symmetric configurations, potentially finding a deeper global minimum.\n\n4. **Second-Order Smoothing (TV-Regularized Mutations)**: High-frequency \"jitter\" in the sequence often leads to localized spikes in the auto-convolution. When applying sensitivity-based reductions, apply a local 3-point Gaussian blur specifically to the targeted indices and their immediate neighbors. This ensures that the reduction is smooth rather than \"point-wise,\" preventing the creation of new high-frequency noise that immediately creates new convolution peaks.\n\n5. **Gradient-Informed Denominator Optimization**: Improve the \"Compensation Move\" by targeting indices with the *absolute lowest* gradient values to increase. Instead of just scaling them, calculate the \"Efficiency Ratio\" $E_i = 1 / (\\text{grad}_i + \\epsilon)$ and use it to distribute a fixed \"increase budget.\" This ensures that the sequence sum (the denominator of the objective) is maximized with the least possible impact on the auto-convolution peak, directly optimizing the balance between the numerator and denominator.",
+    "1. **Implement a Skewed Resolution Time Allocation**: Currently, the budget is split equally among resolutions. Reallocate the search time to a 15%/25%/60% split for $N=256, 512, 768$, respectively. The complex $L_\\infty$ landscape at $N=768$ is significantly more rugged and requires more iterations for the gradient-informed mutations to \"flatten\" the auto-convolution peaks than the initial \"skeleton\" shaping at lower resolutions.\n\n2. **Apply Local Gaussian Smoothing to Gradient Mutations**: To prevent the formation of \"spiky\" sequences that create new high-frequency convolution peaks, apply a local 3-point Gaussian blur (e.g., `[0.25, 0.5, 0.25]`) specifically to the indices targeted by gradient-based reduction and their immediate neighbors. This ensures that the reductions are \"smooth\" rather than point-wise, maintaining the spectral integrity found in high-performing programs like Gen 30.\n\n3. **Dynamic Mutation Strategy Transition**: Shift the mutation probabilities as a function of `progress`. In the early stages (low resolution/early time), prioritize \"Spectral Mutations\" and \"Block Perturbations\" to explore global shapes; in the final 30% of the budget, increase the probability of \"Softmax-weighted Gradient Moves\" to 90%. This transitions the algorithm from a global stochastic search to a dedicated high-resolution local optimizer when it matters most.\n\n4. **Efficiency-Ratio Informed Boosts**: Refine the \"Gradient-based Boost\" by targeting indices with the highest \"Efficiency Ratio,\" defined as $1 / (\\text{grad}_i + \\epsilon)$. Instead of just scaling the lowest-gradient indices, use this ratio to distribute a \"boost budget\" across indices that increase the sequence sum (the denominator) while having the absolute minimum impact on the auto-convolution maximum (the numerator).\n\n5. **Symmetry-Breaking \"Jitter\" Cycles**: The search often gets trapped in local minima within the perfectly symmetric subspace. Introduce a rare mutation (e.g., 2% probability) that intentionally breaks symmetry by applying noise to only one half of the sequence, followed by a period of search, and then a \"re-symmetrization\" step (`seq = (seq + seq[::-1])/2`). This allows the solver to navigate through asymmetric \"bridges\" between different symmetric local optima.",
+    "1. **Implement Skewed Resolution Time Allocation**: The current budget is split linearly among resolutions (1/3 each). Reallocate the search time to a 10%/20%/70% split for $n=256, 512, 768$, respectively. The $L_\\infty$ landscape at $n=768$ is significantly more rugged and requires more iterations for the \"Dual-Action\" gradient-informed mutations to flatten specific convolution peaks than the initial \"skeleton\" shaping at lower resolutions.\n\n2. **Apply Gaussian Smoothing to Gradient Updates**: The current point-wise gradient modifications can introduce high-frequency \"spikes\" that create new local convolution peaks. Apply a local 3-point Gaussian blur (e.g., `[0.25, 0.5, 0.25]`) to the targeted indices or the calculated `grad` array itself before selecting mutation sites. This ensures that reductions and boosts are \"smooth,\" maintaining the spectral integrity that allows the FFT mutations to remain effective.\n\n3. **Incorporate Efficiency-Ratio Boosting**: Refine the \"Gradient-based Boost\" mutation by targeting indices with the highest \"Efficiency Ratio,\" defined as $1 / (\\text{grad}_i + \\epsilon)$. Instead of just scaling the lowest-gradient indices, use this ratio to distribute a \"boost budget\" to indices that increase the sequence sum (the denominator) while having the absolute minimum impact on the auto-convolution maximum (the numerator), thereby more effectively lowering the overall ratio.\n\n4. **Direct Peak-Contribution Targeting**: Supplement the Softmax gradient with a \"Hard-Peak\" mutation. Identify the specific indices $k$ where the convolution $C[k]$ is within 1% of the maximum value, and then target the pairs of sequence indices $(i, j)$ such that $i + j = k$ for reduction. This provides a more surgical alternative to the softmax proxy, which can sometimes \"blur\" the focus when multiple distinct peaks exist in the convolution.\n\n5. **Annealed Symmetry Enforcement**: Instead of treating symmetry as a random mutation (5% probability), implement an \"annealing\" schedule for symmetry. Early in the search (low resolution), allow for more asymmetric exploration to navigate between different local minima; as `progress` approaches 1.0, increase the frequency of the `(seq + seq[::-1])/2.0` operation to 100% to ensure the final sequence benefits from the search-space reduction and spectral properties of symmetric sequences.",
+    "1. **Implement Skewed Resolution Time Allocation**: Reallocate the 10-second search budget from a linear split to a 10%/20%/70% distribution for resolutions $n=256, 512, 768$, respectively. The objective landscape at $n=768$ is significantly more rugged and requires the majority of the iterations to allow the \"Dual-Action\" gradient moves to surgically flatten the numerous local convolution peaks that emerge during interpolation.\n\n2. **Apply Local Smoothing to Gradient Updates**: Instead of applying point-wise modifications to the sequence, apply a 3-point Gaussian blur (kernel `[0.25, 0.5, 0.25]`) to the calculated `grad` array before selecting the indices for reduction or boost. This ensures that the mutations are spatially smooth, preventing the introduction of high-frequency \"spikes\" that immediately create new secondary convolution peaks, thereby maintaining the spectral integrity of the sequence.\n\n3. **Direct Peak-Contribution Targeting (Hard-Peak Mutation)**: Supplement the Softmax-weighted gradient with a \"surgical\" mutation that identifies the exact index $k$ of the maximum convolution value and targets the specific sequence indices $(i, j)$ where $i+j=k$ and the product $seq[i] \\cdot seq[j]$ is largest. By reducing these specific contributors to the global maximum, the algorithm can bypass the \"blurring\" effect of the softmax proxy when multiple peaks have similar magnitudes.\n\n4. **Annealed Symmetry Enforcement**: Transition symmetry from a random mutation to a deterministic constraint as the search nears completion. If `progress > 0.75`, enforce `seq = (seq + seq[::-1]) / 2.0` at the end of every iteration; this effectively halves the search space dimensionality during the most critical refinement phase, focusing all remaining computational power on the $n/2$ degrees of freedom known to contain high-performing solutions.\n\n5. **Gradient-Based Efficiency-Ratio Boosting**: Refine the \"Boost\" mutation by targeting indices with the highest \"Efficiency Ratio,\" defined as $1 / (grad_i + \\epsilon)$. Instead of scaling the lowest-gradient indices uniformly, distribute a \"boost budget\" proportionally to this ratio to prioritize increasing indices that contribute most to the sequence sum (the denominator) while having the absolute minimum impact on the convolution maximum (the numerator).",
+    "1. **Implement Multiplicative \"Peak Pressure\" Updates**: Replace the standard additive/multiplicative gradient moves with a rule that specifically targets the convolution maxima. For the index $k$ where the convolution $C = \\text{seq} * \\text{seq}$ is maximized, identify all pairs $(i, j)$ such that $i+j=k$. Apply a reduction factor to $\\text{seq}[i]$ and $\\text{seq}[j]$ proportional to the product $\\text{seq}[i] \\cdot \\text{seq}[j]$, which stabilizes the $L_\\infty$ landscape more effectively than uniform gradient steps (as seen in the Gen 61 breakthrough, Score -2.00).\n\n2. **Transition to Enforced Symmetry Constraints**: Move symmetry from a random mutation to a deterministic constraint in the latter stages of the search. If `progress > 0.70`, enforce `seq = (seq + seq[::-1]) / 2.0` at the end of every iteration. This halves the search space dimensionality during the refinement phase, allowing the gradient descent to focus computational budget on the $n/2$ degrees of freedom that characterize optimal sequences.\n\n3. **Prioritize Power-Law Seeding**: Refine the `_seed_sequence` function to more heavily weight the Power-Law distribution $(n - i)^{-p}$ with $p \\in [0.45, 0.55]$. Evidence from Gen 65 suggests that this specific \"skeletal\" structure provides a superior global starting point compared to Gaussian or Sine waves, as it naturally balances the sequence sum (denominator) against the distribution of convolution peaks (numerator).\n\n4. **Expand Multi-Resolution Schedule starting at $n=128$**: Introduce a lower initial resolution (e.g., $n=128$) before moving to 256, 512, and 768. Finding the global \"envelope\" of the sequence is significantly faster and more robust at low resolutions; the resulting structure can then be interpolated to higher resolutions for surgical refinement of high-frequency peaks.\n\n5. **High-Beta Softmax with Log-Sum-Exp Stability**: To better approximate the $L_\\infty$ (max) operator, increase the softmax temperature $\\beta$ progressively up to 200-500. To prevent numerical overflow at these levels, always use the stabilized form `w = exp(beta * (c/max_c - 1.0))`. This ensures the gradient moves are concentrated only on the most critical peaks, preventing the \"blurring\" effect that occurs with lower beta values.",
+    "1. **Implement Annealed High-Beta Softmax with Log-Sum-Exp Stability**: Current programs use $\\beta$ up to 200, but to truly break the 1.60 barrier, the softmax needs to more closely approximate the hard $L_\\infty$ maximum. Increase the $\\beta$ range to 500 in the final resolution stage ($n=768$) and ensure numerical stability by using the identity $w = \\exp(\\beta \\cdot (C - \\max(C)))$; this forces the \"Softmax Gradient\" to only update the indices responsible for the single highest peak, preventing the \"blurring\" of mass across sub-optimal peaks.\n\n2. **Adaptive Mutation Weighting (Exploration to Exploitation)**: Transition mutation probabilities dynamically as the search progresses through the resolution ladder. Use higher weights for \"Spectral Mutation\" and \"Block Perturbation\" during the $n=128$ and $n=256$ stages to discover the global \"envelope,\" then shift weight toward \"Sharpened Softmax Gradient\" and \"Peak Pressure\" (up to 80% combined probability) during the final $n=768$ stage for surgical precision in minimizing the convolution maximum.\n\n3. **Deterministic Symmetry Hardening**: While allowing asymmetry is useful for early exploration, the optimal sequences for this problem are known to be highly symmetric. In the final resolution stage ($n=768$), after `progress > 0.85`, move from a 40% chance of symmetry to a 100% deterministic constraint (`seq = (seq + seq[::-1]) / 2.0`) at the end of every iteration; this effectively halves the search space and concentrates the remaining time-budget on the most relevant degrees of freedom.\n\n4. **Windowed Power-Law Seeding**: The power-law distribution $(n-i)^{-p}$ is a successful prior but often suffers from high-frequency noise at the sequence edges ($i \\approx 0$). Refine the `_seed_sequence` function by applying a Tukey or Hann window to the power-law seeds to \"taper\" the edges before the search begins; this provides a smoother initial convolution profile and prevents the gradient descent from wasting iterations correcting edge artifacts.\n\n5. **Coupled \"Peak-to-Gap\" Mass Transfer**: Instead of independent \"Peak Pressure\" and \"Efficiency Boost\" moves, implement a coupled mutation that identifies the indices $(i, j)$ contributing to the max convolution $C[k]$ and the indices $m$ where $C[m]$ is lowest. Directly subtract a small amount $\\delta$ from $seq[i], seq[j]$ and add it to $seq[m]$; this \"water-filling\" approach maintains the sequence sum more effectively than independent multiplicative moves and directly addresses the efficiency gap.",
+    "1. **Push Softmax \u03b2 to \"Hard-Max\" Limits with Numerical Safeguards**: While the current program uses $\\beta$ up to 200, breaking the 1.60 plateau likely requires isolating the exact indices responsible for the peak. Increase the maximum $\\beta$ to 500 during the final $n=768$ stage and ensure stability using the identity $w = \\exp(\\beta \\cdot (C - \\max(C)))$; this \"Super-Sharpened Gradient\" will prevent the blurring of mass and allow for surgical dampening of the $L_\\infty$ norm.\n\n2. **Transition from Exploration to Exploitation via Adaptive Mutation Weights**: The current static mutation probabilities should be replaced with a schedule that shifts focus as the search progresses. Allocate high weights to \"Spectral Mutation\" and \"Block Perturbation\" during the $n=128$ and $n=256$ stages to define the global structure, then transition to over 80% \"Softmax Gradient\" and \"Peak Pressure\" moves during the $n=768$ stage to refine the sequence with high precision.\n\n3. **Enforce Deterministic Symmetry Hardening in the Final Phase**: While early-stage asymmetry allows the search to navigate around local optima, the optimal solutions for the Autocorrelation (AC) problem are historically symmetric. In the final resolution stage ($n=768$), especially after `progress > 0.85`, the algorithm should switch from a 40% probability to a 100% deterministic symmetry constraint (`seq = (seq + seq[::-1]) / 2.0`) to effectively halve the search dimensionality and concentrate resources on the most promising region.\n\n4. **Implement Coupled \"Peak-to-Gap\" Mass Migration**: Instead of independent \"Peak Pressure\" (reduction) and \"Efficiency Boost\" (addition) moves, implement a coupled mutation that identifies the indices $(i, j)$ contributing to the max convolution $C[k]$ and the indices $m$ where $C[m]$ is lowest. Directly subtract a small amount $\\delta$ from $seq[i], seq[j]$ and add it to $seq[m]$; this \"water-filling\" approach maintains the sequence sum more effectively and directly addresses the efficiency gap.\n\n5. **Frequency-Selective Spectral Damping**: Refine the spectral mutation to be more targeted than a blanket 80% damping. Analyze the FFT of the sequence and specifically damp the frequency bands that show the highest power relative to the \"power-law\" ideal; this preserves the beneficial global \"envelope\" discovered at low resolutions while suppressing the high-frequency \"jitter\" often introduced by the stochastic gradient moves.",
+    "1. **Implement Coupled \"Peak-to-Gap\" Mass Migration**: Instead of performing independent \"Peak Pressure\" (reduction) and \"Efficiency Boost\" (addition) moves, combine them into a single atomic operation. Identify indices contributing to the convolution maximum ($C_{max}$) and those contributing to the convolution minimum ($C_{min}$), then subtract mass from the former and add it to the latter. This \"water-filling\" approach directly flattens the $L_\\infty$ norm of the convolution while keeping the sequence sum constant, providing more stable convergence than stochastic independent moves.\n\n2. **Push Softmax $\\beta$ to \"Hard-Max\" Limits (500+) with Log-Stability**: To break the 1.60 plateau, the algorithm must isolate the exact sequence indices responsible for the peak convolution values. Increase the maximum $\\beta$ to 500 or higher during the final $n=768$ stage, but ensure numerical stability using the identity $w = \\exp(\\beta \\cdot (C / \\max(C) - 1.0))$. This prevents the `NaN` or `Inf` values that caused failures in Gen 99 while allowing for the \"surgical\" precision needed to damp specific peaks.\n\n3. **Enforce Deterministic Symmetry Hardening in the Final Phase**: While maintaining some asymmetry is useful for navigating local optima early on, the optimal sequences for this task are theoretically symmetric. Shift from a probabilistic symmetry check to a deterministic constraint (`seq = (seq + seq[::-1]) / 2.0`) once progress exceeds 85% of the time budget. This effectively halves the search dimensionality at the moment of highest resolution, allowing the search to focus all remaining iterations on refining the symmetric envelope.\n\n4. **Transition from Exploratory to Surgical Mutation Weights**: Replace the current static mutation probabilities with a schedule that adapts based on the search progress and resolution. Allocate high weights (e.g., 60%) to \"Spectral Mutation\" and \"Block Perturbation\" during the $n=128$ and $n=256$ stages to define the global shape, then transition to over 85% combined weight for \"Sharpened Softmax\" and \"Peak-to-Gap\" moves during the final $n=768$ stage for high-precision exploitation.\n\n5. **Frequency-Selective Spectral Damping via Power-Law Fitting**: Refine the spectral mutation to target frequencies that deviate from the \"ideal\" power-law decay ($k^{-p}$) identified in successful seeds like Gen 90 and 96. Instead of a blanket 80% damping of high frequencies, calculate the sequence's current power spectrum and specifically damp bands that show excess energy relative to the $k^{-0.5}$ envelope. This preserves the beneficial global structure while suppressing the high-frequency \"jitter\" often introduced by stochastic gradient-proxy moves.",
+    "1. **Implement Atomic Peak-to-Gap Mass Migration**: Instead of performing independent \"Sharpened Softmax\" (reduction) and \"Efficiency Boost\" (addition) moves, combine them into a single atomic operation. In one step, identify the indices with the highest contribution to the convolution maximum using the high-beta gradient and subtract mass, then simultaneously add that exact amount of mass to indices identified by the inverse gradient (convolution minima). This \"water-filling\" approach maintains the sequence sum internally, leading to more stable convergence and less reliance on the global normalization function.\n\n2. **Push Softmax $\\beta$ to \"Ultra-Sharp\" Limits (500+) with Log-Stability**: To break the 1.60 plateau, the algorithm must isolate the exact sequence indices responsible for the peak convolution values. Increase the maximum $\\beta$ from 200 to 500 or higher during the final $n=768$ stage, ensuring numerical stability using the identity $w = \\exp(\\beta \\cdot (C / \\max(C) - 1.0))$. This creates a \"Dirac-like\" selection mask that allows for the surgical precision needed to shave off the final fractions of the convolution $L_\\infty$ norm.\n\n3. **Transition to Deterministic Symmetry Hardening in the Final Phase**: While maintaining asymmetry is useful for navigating local optima at low resolutions, the optimal sequence is theoretically symmetric. Shift from the current probabilistic symmetry check to a deterministic constraint (`seq = (seq + seq[::-1]) / 2.0`) once the search enters the final 15% of the time budget or the highest resolution ($n=768$). This effectively halves the search dimensionality at the moment of highest computational cost, allowing the search to focus all remaining iterations on refining the symmetric envelope.\n\n4. **Replace Fixed Time-Shares with Plateau-Triggered Upscaling**: Instead of using hardcoded time shares (e.g., 0.10, 0.25, 0.50), implement a \"patience\" mechanism where the resolution only increases after the current scale has failed to produce an improvement for a set number of iterations. This ensures that the global \"envelope\" of the sequence is fully optimized at lower resolutions (128 and 256) before committing the remaining time to high-frequency refinement at $n=768$, preventing the search from carrying sub-optimal global shapes into the expensive final stage.\n\n5. **Frequency-Selective Spectral Smoothing via $1/f^\\alpha$ Envelope Fitting**: Refine the spectral mutation by calculating the current sequence's power spectrum and damping frequencies that deviate significantly from an \"ideal\" $1/f^\\alpha$ decay (where $\\alpha \\approx 0.5$). Instead of a blanket 40% damping of high frequencies, this approach preserves the beneficial global structure while specifically suppressing the high-frequency \"jitter\" or \"spikiness\" often introduced by stochastic gradient-proxy moves at high resolution.",
+    "1. **Implement Atomic Peak-to-Gap Mass Migration**: Replace independent \"Sharpened Softmax\" and \"Efficiency Boost\" moves with a single atomic operation that identifies indices contributing to convolution maxima (using high-beta softmax) and convolution minima simultaneously. Shift \"mass\" directly from peak-contributing indices to valley-contributing indices to maintain the sequence sum internally, which provides more stable convergence than relying on global normalization after separate additive/multiplicative moves.\n\n2. **Push Softmax $\\beta$ to \"Ultra-Sharp\" Limits (500+) with Log-Stability**: To break the 1.60 plateau, the algorithm must isolate the exact sequence indices responsible for the peak convolution values with higher precision. Increase the maximum $\\beta$ from 200 to 500 or higher during the final $n=768$ stage, ensuring numerical stability by using the log-space identity $w = \\exp(\\beta \\cdot (C / \\max(C) - 1.0))$, effectively creating a \"Dirac-like\" selection mask for surgical peak reduction.\n\n3. **Transition to Deterministic Symmetry Hardening in the Final Phase**: While maintaining asymmetry helps navigate local optima at low resolutions, the optimal sequence is theoretically symmetric. Shift from probabilistic symmetry checks to a deterministic constraint (`seq = (seq + seq[::-1]) / 2.0`) once the search enters the final 15% of the time budget or the highest resolution ($n=768$), effectively halving the search dimensionality at the moment of highest computational cost.\n\n4. **Replace Fixed Time-Shares with Plateau-Triggered Upscaling**: Instead of hardcoded time shares (0.10, 0.25, 0.50), implement a \"patience\" mechanism where the resolution only increases after the current scale has failed to produce an improvement for a set number of iterations (e.g., 50-100). This ensures the global \"envelope\" is fully optimized at lower resolutions before committing the remaining time to high-frequency refinement at $n=768$, preventing the carry-over of sub-optimal global shapes.\n\n5. **Frequency-Selective Spectral Smoothing via Power-Law Envelope Fitting**: Refine the spectral mutation by calculating the sequence's power spectrum and specifically damping components that deviate significantly from a $1/f^{0.5}$ decay. Instead of a blanket 40% damping of high frequencies, this approach preserves the beneficial global structure found in high-performing power-law seeds while suppressing the high-frequency \"jitter\" introduced by stochastic gradient-proxy moves.",
+    "1. **Implement Atomic Peak-to-Valley Mass Migration**: Instead of treating \"Peak Pressure\" (shaving peaks) and \"Efficiency Boost\" (raising valleys) as independent operations, implement a combined move that identifies indices contributing to convolution maxima and minima simultaneously. By subtracting a small multiplicative amount from peak-contributing indices and redistributing that exact mass to indices that contribute to the convolution's \"valleys,\" you maintain the sequence sum $\\sum A_i$ internally. This provides more stable convergence than relying on global normalization after separate moves and directly flattens the $L_\\infty$ norm.\n\n2. **Push Softmax $\\beta$ to \"Ultra-Sharp\" Limits (500+)**: To break the 1.60 plateau, increase the maximum softmax $\\beta$ from 200 to 500 or higher during the final $n=768$ resolution stage. Use the numerically stable log-space identity $w = \\exp(\\beta \\cdot (C / \\max(C) - 1.0))$ to create a near-mask for the exact sequence indices responsible for the peak. This allows for \"nanosurgery\" on the sequence, suppressing the specific indices causing the $L_\\infty$ bottleneck without affecting the global power-law envelope.\n\n3. **Transition to Deterministic Symmetry in the Final Phase**: While the current program uses probabilistic symmetry, the theoretical optima for this problem are symmetric. Shift from 80% probabilistic symmetry to a 100% deterministic constraint (`seq = (seq + seq[::-1]) / 2.0`) once the search enters the final resolution ($n=768$) or the last 15% of the time budget. This effectively halves the search dimensionality at the most computationally expensive stage, allowing for more iterations per second when refining high-frequency details.\n\n4. **Replace Fixed Time-Shares with Plateau-Triggered Upscaling**: Rather than using hardcoded time shares (10%, 25%, 50%), implement a \"patience\" mechanism where the resolution only increases after the current scale has failed to produce a significant improvement for a set number of iterations (e.g., 100). This ensures the global \"envelope\" is fully optimized at lower resolutions (where iterations are cheap) before committing the remaining time to fine-tuning at $n=768$, preventing the algorithm from carrying over sub-optimal global shapes into the final stage.\n\n5. **Formalize Multiplicative Updates as Mirror Descent Steps**: Replace the current heuristic multiplicative moves (`seq *= (1.0 - sigma)`) with a formal Mirror Descent step using a Log-barrier or Entropic projection. Update the sequence using $A_{new} = A \\cdot \\exp(-\\eta \\cdot \\nabla_{conv})$, where $\\nabla_{conv}$ is the gradient of the max-convolution objective. This approach naturally respects the non-negativity constraint and has been shown in Gens 121-127 to be more effective than additive Gaussian noise for preserving the delicate power-law structure of high-performing sequences.",
+    "1. **Implement Unified Peak-to-Valley Mass Migration**: Instead of independent \"Peak Pressure\" (shaving) and \"Efficiency Boost\" (raising) moves, implement a combined move that identifies indices $(i, j)$ contributing to the convolution maximum and indices contributing to the minimum. Subtract a small multiplicative amount from peak-contributing indices and redistribute that exact mass to the valley-contributing indices; this preserves the sequence sum $\\sum A_i$ internally and directly flattens the $L_\\infty$ norm more efficiently than global normalization.\n\n2. **Push Softmax $\\beta$ to \"Nanosurgery\" Limits (500-1000)**: To break the 1.60 plateau, significantly increase the softmax $\\beta$ from the current max of 200 to 500 or higher during the final $n=768$ resolution stage. Use the numerically stable identity $w = \\exp(\\beta \\cdot (C / \\max(C) - 1.0))$ to create an ultra-sharp mask that isolates only the exact sequence elements responsible for the current convolution spike, allowing for surgical reductions that don't degrade the rest of the sequence's \"envelope.\"\n\n3. **Enforce Deterministic Half-Length Optimization in the Final Phase**: Since theoretical optima are symmetric, once the search reaches the final resolution ($n=768$) or the last 20% of the time budget, switch to a mode that only mutates the first $n/2$ elements and mirrors them to the second half (`seq[n//2:] = seq[:n//2][::-1]`). This effectively halves the search dimensionality at the most computationally expensive stage, doubling the number of refinement iterations possible within the remaining time budget.\n\n4. **Replace Fixed Time-Shares with Plateau-Triggered Upscaling**: Rather than using hardcoded time shares (10%, 25%, 50%), implement a \"patience\" mechanism where the resolution only increases after the current scale has failed to produce a significant improvement for a set number of iterations (e.g., 100-200). This ensures the global \"envelope\" is fully optimized at lower resolutions where iterations are computationally cheap before committing the remaining time to high-precision fine-tuning at $n=768$.\n\n5. **Apply Envelope-Preserving Spectral Smoothing**: Periodically apply a low-pass filter via FFT to the best sequence to re-impose a smooth power-law envelope, as aggressive \"peak surgery\" can introduce high-frequency \"jitter\" that creates new, smaller spikes. By slightly dampening high-frequency components (e.g., `f[int(len(f)*0.1):] *= 0.95`) every few successful moves, you ensure the sequence maintains the smooth, low-convolution shape characteristic of the best-performing $x^{-0.5}$ power-law structures.",
+    "1. **Implement Unified Peak-to-Valley Mass Migration**: Instead of performing independent \"Peak Pressure\" (shaving) and \"Efficiency Boost\" (raising) moves, implement a combined move that identifies indices $(i, j)$ contributing to the convolution maximum and indices contributing to the minimum. Subtract a small multiplicative amount from peak-contributing indices and redistribute that exact mass to the valley-contributing indices; this preserves the sequence sum internally and flattens the $L_\\infty$ norm more directly than global normalization.\n\n2. **Push Softmax $\\beta$ to \"Nanosurgery\" Limits (500-1000)**: To break the 1.60 plateau, significantly increase the softmax $\\beta$ from the current max of 200 to 500 or higher during the final $n=768$ resolution stage. Use the numerically stable identity $w = \\exp(\\beta \\cdot (C / \\max(C) - 1.0))$ to create an ultra-sharp mask that isolates only the exact sequence elements responsible for the current convolution spike, allowing for surgical reductions that don't degrade the rest of the sequence's smooth envelope.\n\n3. **Transition to Deterministic Half-Length Optimization in the Final Phase**: Since theoretical optima are symmetric, once the search reaches the final resolution ($n=768$) or the last 25% of the time budget, switch to a mode that only mutates the first $n/2$ elements and mirrors them to the second half (`seq[n//2:] = seq[:n//2][::-1]`).

This ensures the global \"envelope\" is fully optimized at lower resolutions where iterations are computationally cheap before committing the maximum possible remaining time to high-precision fine-tuning at $n=768$.\n\n5. **Apply Gradient-Based Gaussian Smoothing**: After calculating the softmax gradient or peak pressure indices, apply a small Gaussian kernel to the \"delta\" or \"mask\" before applying it to the sequence. This prevents the \"nanosurgery\" from introducing high-frequency \"jitter\" or jagged edges, which often create new, secondary convolution spikes that prevent the $L_\\infty$ norm from dropping below the 1.60 threshold.",
+    "1. **Implement Mass-Preserving Peak-to-Valley Migration**: Build upon the \"Peak Pressure Move\" and \"Efficiency Boost\" by combining them into a single deterministic step. Identify indices $i, j$ whose product $A_i \\cdot A_j$ contributes most to the maximum convolution value and simultaneously identify indices whose contributions are minimal; subtract a small multiplicative $\\epsilon$ from the peak-contributing elements and redistribute that exact sum to the valley-contributing elements. This maintains the sequence sum $\\sum A = n$ internally while directly flattening the $L_\\infty$ norm of the convolution.\n\n2. **Escalate Softmax Beta for \"Nanosurgery\" (500-1000)**: To move beyond the 1.60 plateau, increase the softmax $\\beta$ from the current maximum of 200 to at least 500 during the final $n=768$ resolution. Use the numerically stable identity $w = \\exp(\\beta \\cdot (C / \\max(C) - 1.0))$ to create an ultra-precise mask that isolates only the specific sequence elements responsible for the absolute peak. This allows the optimizer to shave the primary spike without inducing collateral damage (jitter) in the rest of the smooth envelope.\n\n3. **Switch to Deterministic Half-Length Optimization in the Final Phase**: Since the theoretical and empirical optima are symmetric, once the program enters the final 30% of the time budget or the $n=768$ resolution, strictly optimize only the first $n/2$ elements and enforce symmetry via `seq[n//2:] = seq[:n//2][::-1]`. By effectively halving the search dimensionality, the algorithm can perform twice as many \"surgical\" iterations per second at the most computationally expensive resolution.\n\n4. **Apply Gradient Smoothing via Gaussian Kernels**: Before applying a \"Peak Pressure\" or \"Softmax Gradient\" update to the sequence, convolve the modification vector (the delta or multiplicative mask) with a narrow Gaussian kernel ($\\sigma \\approx 1-3$ indices). This prevents the \"nanosurgery\" moves from introducing high-frequency jaggedness or \"spikes\" in the sequence envelope, which often create new, secondary convolution peaks that stall progress near the 1.60 threshold.\n\n5. **Transition from Fixed Time-Shares to Progress-Based Upscaling**: Replace the hardcoded `time_shares` ladder with a \"patience\" trigger for resolution increases. Set a threshold for improvement (e.g., if the best score hasn't improved by 0.1% in 100 iterations); only then upscale from $n=256$ to $n=512$. This ensures the global \"macro-envelope\" is fully converged at cheaper, low-resolution scales before the algorithm commits the majority of the remaining budget to high-precision fine-tuning at $n=768$.",
+    "1. **Implement Mass-Preserving Peak-to-Valley Migration**: Integrate the \"Peak Pressure Move\" and \"Efficiency Boost\" into a single deterministic operation. Subtract a multiplicative $\\epsilon$ from the indices contributing most to the convolution peak and redistribute that exact amount of mass to the indices identified by the gradient as \"valleys.\" This maintains the internal sequence sum $\\sum A = n$ more naturally than global normalization alone, directly flattening the $L_\\infty$ profile without shifting the overall scale.\n\n2. **Escalate Softmax Beta for \"Nanosurgery\" (500-1000)**: To break the 1.60 barrier, increase the softmax $\\beta$ from the current max of 200 to 1000 during the final $n=768$ resolution. Use the numerically stable formula $w = \\exp(\\beta \\cdot (C / \\max(C) - 1.0))$ to create an ultra-precise mask that isolates only the specific sequence elements responsible for the absolute peak. This allows the optimizer to shave the primary spike with extreme precision, avoiding the collateral jitter that limits progress at lower beta values.\n\n3. **Transition to Strict Half-Length Optimization in the Final Phase**: Once the program reaches the $n=768$ resolution or the final 30% of the time budget, switch to optimizing only the first $n/2$ elements and enforce symmetry via `seq[n/2:] = seq[:n/2][::-1]`. By effectively halving the search dimensionality, the algorithm can perform twice as many \"surgical\" iterations per second at the most computationally expensive scale, which is critical for finding the fine-grained refinements needed below 1.60.\n\n4. **Apply Gaussian Smoothing to Mutation Deltas**: Before applying a \"Peak Pressure\" or \"Softmax Gradient\" update to the sequence, convolve the modification vector with a narrow Gaussian kernel ($\\sigma \\approx 1-2$ indices). This prevents \"nanosurgery\" from introducing high-frequency jaggedness or local \"spikes\" in the sequence envelope, which frequently create new, secondary convolution peaks that stall convergence in the final iterations.\n\n5. **Utilize Progress-Based Adaptive Resolution Upscaling**: Replace the fixed `time_shares` ladder with a \"patience\" trigger for resolution increases (e.g., upscale from $n=256$ to $n=512$ only if the best score hasn't improved by 0.05% in 50 iterations). This ensures the global \"macro-envelope\" is fully optimized at lower, computationally cheaper scales before committing the majority of the remaining time budget to high-precision fine-tuning at $n=768$.",
+    "1. **Implement Numerically Stable High-Beta Softmax for Nanosurgery**: To break the 1.60 performance ceiling, escalate the softmax $\\beta$ to 1000 during the final $N=768$ resolution phase using the stable formula `np.exp(beta * (c / np.max(c) - 1.0))`. This ultra-high precision mask allows the optimizer to isolate and subtract mass from only the exact sequence elements responsible for the $L_\\infty$ peak, avoiding the collateral \"jitter\" at lower $\\beta$ values that often prevents fine-grained convergence.\n\n2. **Execute Mass-Preserving Peak-to-Valley Migration**: Instead of independent multiplicative reductions or increases, implement a \"Migration Move\" that subtracts mass from indices contributing to the convolution peak and redistributes it to the \"valleys\" (indices with the lowest gradient sensitivity). This deterministic redistribution maintains the internal sequence sum $\\sum A = n$ more naturally than global normalization, directly flattening the $L_\\infty$ profile without shifting the overall scale of the sequence.\n\n3. **Transition to Strict Half-Length Optimization in the Final Phase**: Once the program reaches the $N=768$ resolution or the final 30% of the time budget, switch to optimizing only the first $n/2$ elements and enforce symmetry via `seq[n/2:] = seq[:n/2][::-1]`. Halving the search dimensionality in the most computationally expensive phase allows the algorithm to perform significantly more \"surgical\" iterations per second, focusing the remaining budget on refining the symmetric form known to be optimal.\n\n4. **Apply Gaussian Smoothing to Mutation Deltas**: Convolve update vectors (like the gradient proxy or peak-pressure adjustments) with a narrow Gaussian kernel ($\\sigma \\approx 1-2$ indices) before applying them to the sequence. This smoothing prevents \"nanosurgery\" from introducing high-frequency jaggedness or local \"spikes\" in the sequence envelope, which frequently create new, secondary convolution peaks that stall progress in late-stage optimization.\n\n5. **Utilize Progress-Based Adaptive Resolution Upscaling**: Replace the fixed `time_shares` ladder with a \"patience\" trigger that upscales the resolution (e.g., from $N=256$ to $N=512$) only when the best score has failed to improve by a threshold (e.g., 0.02%) for 100 iterations. This ensures the global \"macro-envelope\" of the sequence is fully converged at computationally cheaper scales before committing the majority of the time budget to high-resolution refinement.",
+    "1. **Implement Ultra-High Beta \"Nanosurgery\" for Peak Isolation**: Escalate the softmax $\\beta$ from the current maximum of 200 up to 1000 during the final $n=768$ resolution phase. Using the numerically stable formula $\\exp(\\beta \\cdot (c / \\max(c) - 1.0))$, an ultra-high $\\beta$ transforms the gradient into a \"surgical\" mask that isolates only the exact coefficients responsible for the $L_\\infty$ norm peak, preventing the collateral \"jitter\" that often limits convergence near the 1.60 barrier.\n\n2. **Execute Coupled Mass-Preserving Migration**: Replace independent multiplicative increases and decreases with a \"Migration Move\" that subtracts mass from indices with the highest gradient sensitivity (peaks) and adds it to indices with the lowest sensitivity (valleys). This deterministic redistribution flattens the convolution profile while keeping the sequence sum $\\sum A$ perfectly constant, maintaining numerical stability and objective scale without relying on global normalization.\n\n3. **Transition to Half-Length Search for Efficiency**: In the final 30% of the time budget or once reaching $n=768$, switch to optimizing only the first $n/2$ elements and enforce symmetry via `seq[n/2:] = seq[:n/2][::-1]`. Halving the search dimensionality in the most computationally expensive phase allows the algorithm to perform nearly double the iterations per second, focusing the remaining budget on refining the symmetric form which has proven to be optimal in high-performing programs.\n\n4. **Apply Gaussian Smoothing to Mutation Deltas**: Convolve the surgical update vectors (gradient-based adjustments) with a narrow Gaussian kernel ($\\sigma \\approx 1.5$ indices) before applying them to the sequence. This smoothing prevents targeted mutations from introducing high-frequency \"jaggedness\" or local spikes in the sequence envelope, which typically generate new, secondary convolution peaks that cause the optimizer to stall in late-stage refinement.\n\n5. **Utilize Progress-Based Adaptive Resolution Upscaling**: Replace the fixed `time_shares` ladder with a \"patience\" trigger that upscales the resolution (e.g., from 512 to 768) only when the best score has failed to improve by a threshold (e.g., 0.01%) for 50 iterations. This ensures the macro-envelope of the sequence is fully converged at computationally cheaper scales before committing the bulk of the 10-second budget to high-fidelity, high-cost iterations at $n=768$.",
+    "1. **Implement Explicit Half-Length Search for the $n=768$ Phase**: Since symmetry is nearly 100% enforced in the final stages of the best program, explicitly reduce the search space by optimizing only the first $n/2$ elements and reflecting them to form the full sequence. This effectively doubles the iteration speed at the most computationally expensive resolution, allowing for deeper refinement of the symmetric profile which has consistently yielded the 1.60 score.\n\n2. **Execute Coupled \"Peak-to-Valley\" Mass Migration**: Replace the independent multiplicative updates (currently $m\\_type < 0.50$ and $m\\_type < 0.80$) with a single operator that moves mass directly from indices with high gradient sensitivity to those with low sensitivity. By subtracting a small delta from \"peak-contributing\" indices and adding it to \"valley-filling\" indices, you maintain a constant $\\sum A$ and prevent the optimizer from drifting into regions of the search space that require global re-normalization.\n\n3. **Escalate to Ultra-High Beta (1000+) with Numerical Stability**: Extend the softmax $\\beta$ annealing range from the current max of 200 up to 1000 or higher during the final 20% of the budget. To prevent overflow, strictly use the `np.exp(beta * (c / max_c - 1.0))` formulation; this \"surgical\" precision isolates only the absolute maximum of the convolution, ensuring that late-stage mutations target the $L_\\infty$ norm exclusively without introducing collateral noise in the rest of the sequence.\n\n4. **Apply Gaussian Smoothing to Gradient Updates**: Before applying the calculated gradient to the sequence, convolve the update vector with a narrow Gaussian kernel ($\\sigma \\approx 1.0 - 2.0$). This prevents \"nanosurgery\" from creating high-frequency \"jaggedness\" or local spikes in the sequence envelope, which often lead to new, secondary convolution peaks that stall convergence near the 1.60 barrier.\n\n5. **Transition to Patience-Based Adaptive Resolution Scaling**: Replace the fixed `time_shares` ladder with a trigger that upscales the resolution only when the objective has failed to improve by a small epsilon (e.g., $10^{-5}$) for a fixed number of iterations (patience). This ensures that the macro-envelope of the sequence is fully optimized at lower resolutions (128, 256) before committing the majority of the time budget to the high-cost $n=768$ refinement."

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+# Detailed Program Evaluation Analysis
+
+## Successful Algorithmic Patterns
+
+*   **Targeted Convolution Peak Reduction:** The most significant performance improvement (1.57 in **Generation 5**) resulted from a specialized "gradient-informed" mutation. This technique calculates the convolution of the sequence with itself, identifies the indices where the convolution reaches its maximum (peaks), and reduces the specific sequence elements that contribute to those peaks. This is implemented by calculating `grad[k] += seq[p - k]` for peak index `p`, then applying `seq *= (1.0 - alpha * grad/max(grad))`.
+*   **Domain-Specific Binomial Seeding:** **Generation 5** and **Generation 3** leveraged the binomial sequence (where $a_i = a_{i-1} \cdot \frac{2i-1}{2i}$) as a starting point. This specific mathematical seed provides a high-quality initial state that outperforms generic noise or simple sines, contributing to the record score of 1.57.
+*   **Progressive Resolution Upsampling:** Every successful program (**Generations 0, 1, 3, 4, 5, 6, 7, 9**) utilized some form of dynamic sequence lengthening via interpolation (e.g., `np.interp` or `np.linspace`). Starting the search at lower lengths (128 or 256) and upsampling to 1024 allows the algorithm to find optimal global shapes quickly before refining high-frequency details.
+*   **Diverse Multi-Start Initializations:** Programs achieving scores below 1.70 (**Generations 4, 5, 6**) utilized a wide array of initial shapes, including chirps, harmonic sine waves, ramps, and binomial profiles. This diversity prevents the search from becoming trapped in local minima inherent in the autocorrelation objective.
+
+## Ineffective Approaches
+
+*   **Analytical/Subgradient Instability:** **Generation 8** attempted a sophisticated Taylor sequence initialization and subgradient descent. This failed (score 0.0), indicating that pure gradient-based methods may be numerically unstable or sensitive to the non-negativity constraints without robust stochastic fallback.
+*   **Missing Runtime Dependencies:** **Generation 2** implemented a complex peak-flattening logic but failed entirely due to basic Python errors (missing `import numpy` and `import time`), highlighting that even sophisticated algorithms fail without proper environment setup.
+*   **Lack of Scale Invariance Awareness:** While the objective $2n \cdot \text{max}(B) / (\sum A)^2$ is scale-invariant, programs that failed to normalize their sequences during mutation (**Generation 1** vs. **Generation 5**) often struggled with numerical overflow or precision issues when sequences were repeatedly scaled.
+
+## Implementation Insights
+
+*   **Effective Normalization Strategy:** The current best program (**Generation 5**) uses a normalization function `_normalize_scale` that clips values to non-negative and scales them such that the sum equals the length of the sequence. This keeps the values in a range that is numerically stable for both `np.convolve` and `np.power` mutations.
+*   **Local Search Mutation Mix:** The successful search in **Generation 5** balances four distinct mutation types: block noise (30%), multi-peak gradient reduction (35%), element swapping (20%), and smoothing/power transformations (10%). This distribution ensures both coarse shape adjustment and fine-grained refinement.
+*   **Peak-to-Sequence Mapping:** Successful implementations (**Generation 3, 5, 9**) correctly identified that the convolution value at index $p$ is a sum of products $a_i \cdot a_{p-i}$. By targeting only the indices involved in the maximum convolution value, they achieve much faster convergence than random point mutations.
+
+## Performance Analysis
+
+*   **Comparison of Best Values:** **Generation 5** achieved the top performance of 1.57. This is a notable improvement over **Generation 4** (1.67) and **Generation 6** (1.69). The 6-10% improvement is directly attributable to the refinement of the peak-reduction gradient logic and the inclusion of binomial seeds.
+*   **Length Correlation:** There is a clear correlation between sequence length and objective performance. Programs utilizing the maximum allowed length of 1024 (**Generations 1, 3, 5**) generally achieved better results than those stopping at shorter lengths like 284 (**Generation 4**) or 768 (**Generation 0**), provided the search strategy was effective.
+*   **Success of Stochastic Search:** Despite the mathematical nature of the problem, stochastic local search with targeted heuristics (as seen in **Generations 5 and 9**) consistently outperformed the more "pure" mathematical approaches attempted in **Generations 2 and 8**, which failed to produce valid results.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Adaptive Gradient-Step Scaling:** Instead of a fixed 0.04 alpha in the "Multi-peak gradient reduction" mutation, implement an adaptive step size or a line-search approach. Since the objective is scale-invariant, the sequence should be re-normalized after every gradient step, and the step size could be halved if a mutation fails to improve the score, allowing for finer convergence around the 1.57 optima.
+
+2. **Integrate "Generalized Binomial" and Windowed Seeds:** The binomial sequence $a_i = a_{i-1} \cdot \frac{2i-1}{2i}$ is a powerful seed, but its performance might be improved by parameterizing it as $a_i = a_{i-1} \cdot \frac{2i-k}{2i}$ for $k \in [0.5, 1.5]$. Additionally, applying windowing functions (like Tukey or Hann windows) to initial seeds can help suppress edge effects in the convolution that contribute to central peaks.
+
+3. **Incorporate Success-Based Adaptive Mutation Probabilities:** Replace the fixed mutation thresholds (0.30, 0.65, etc.) with a dynamic system that tracks which mutation type has yielded the most "best_val" improvements during the run. By increasing the probability of successful mutations (likely the gradient reduction and upsampling) and decreasing failing ones (like random swaps if they prove too destructive at high lengths), the search becomes more efficient as the deadline approaches.
+
+4. **Enforce Sequence Symmetry via Mirroring Mutations:** The convolution of a symmetric sequence often exhibits more predictable peak behavior. Add a mutation that replaces the sequence with its average mirror image `(seq + seq[::-1]) / 2.0` or simply mirrors one half to the other; this reduces the search space dimensionality and may help stabilize the gradient-informed peak reduction.
+
+5. **Transition to a Simulated Annealing Acceptance Criterion:** The current "greedy" local search (`val < best_val`) is prone to getting trapped in local minima, as seen in the plateauing scores around 1.6-1.7. Implementing a simple Metropolis-Hastings acceptance criterion—where slightly worse sequences are accepted with a probability $P = \exp(-\Delta V / T)$ and a cooling temperature $T$—could allow the algorithm to escape suboptimal "peak configurations" and find more global optima.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Systematic Binomial Sweep as a Theoretical Anchor**: The most successful strategy remains initializing with the sequence family $(1-z)^{-k/2}$. The **Current Best Program (1.57 value)** performs a precise sweep of $k$ from 0.94 to 1.06 across 41 points. **Generation 93** and **Generation 96** also utilized binomial seeds to achieve competitive values of 1.58, confirming that this initialization places the optimizer in the correct basin for the $\pi/2 \approx 1.57$ theoretical limit.
+*   **Resolution Laddering for High-Resolution Refinement**: Progressively increasing sequence length (e.g., $1024 \to 1536 \to 2048$) allows the optimizer to capture coarse structures before refining high-frequency details. **Generation 95** and **Generation 98** reached a value of 2.00 at $n=2048$ using this laddering approach. **Generation 96** successfully combined laddering with binomial initialization to reach 1.58 at $n=2048$, the best result currently seen at that maximum resolution.
+*   **Momentum-Augmented Entropic Mirror Descent (EMD)**: Utilizing multiplicative updates ($seq \cdot e^{-\eta \cdot velocity}$) with a momentum term (typically 0.75) is the standard for high-performing programs. The **Current Best Program** and **Generation 95** use this to maintain the non-negativity constraint while navigating the non-smooth landscape of the autoconvolution maximum.
+*   **Annealed Softmax for Gradient Approximation**: To optimize the $L_\infty$ norm of the convolution, successful programs approximate the gradient using a softmax-weighted sum of the convolution peaks. The **Current Best Program** and **Generation 96** use an annealed approach, increasing the exponent (up to 1000) over time to transition from smoothing multiple peaks to aggressively targeting the absolute maximum.
+
+## Ineffective Approaches
+
+*   **Numerical Instability in Gradient Weights**: Using extremely high exponents in softmax calculations without proper normalization leads to catastrophic failure. **Generation 91** failed (score 0.0) due to numerical overflows when using exponents up to 900 without the robust scaling seen in the **Current Best Program**, which uses `exp(exponent * (c - m) / m)` to keep the argument non-positive.
+*   **Execution Environment Omissions**: Several sophisticated approaches failed due to basic implementation errors. **Generation 92** and **Generation 99** both achieved scores of 0.0 despite using theoretically sound Mirror Descent because they failed to include necessary imports (`numpy`, `time`) within the executable block.
+*   **Resolution Scaling Instability**: While laddering is often effective, it introduces risk. **Generation 94** failed validation during the transition from $n=1024$ to $n=1536$. This suggests that interpolation or re-normalization during resolution changes must be handled with extreme care to maintain the objective's properties.
+*   **Dimensionality vs. Budget Trade-off**: Programs targeting $n=2048$ (**Generations 90, 95, 98**) often struggle to match the 1.57 value achieved at $n=1536$ (**Current Best Program**). The increased dimensionality at $n=2048$ makes the search more susceptible to local minima or insufficient convergence within the 10-second budget, often plateauing at 2.00 or 1.58.
+
+## Implementation Insights
+
+*   **Spectral Gradient Smoothing**: To prevent multiplicative updates from introducing high-frequency noise that spikes the $L_\infty$ norm, the **Current Best Program** applies a 3-point Gaussian-like smoothing kernel to the gradient. It also uses a "cooling" schedule for this width (0.15 to 0.05) to allow finer adjustments as the search nears a local optimum.
+*   **Granular Multiplicative Line Search**: Rather than relying on a fixed learning rate, the **Current Best Program** tests seven discrete step sizes (from 0.0002 to 0.02) at each iteration. This ensures monotonic improvement and prevents the "overshooting" common in exponential update rules.
+*   **Symmetry as a Dimensionality Reducer**: Programs achieving values of 2.00 or better (**Gen 95, 97, 98**) often enforce strict sequence symmetry ($a_i = a_{n-i-1}$). This effectively halves the search space, allowing the optimizer to converge more quickly within the time limit.
+*   **Efficient Gradient Computation**: The **Current Best Program** computes the gradient of the max-convolution using `np.correlate(weights, best_seq, mode='valid')`. This recognizes that the sensitivity of the convolution peak to a change in $a_i$ is determined by the cross-correlation of the peak weights with the sequence itself.
+
+## Performance Analysis
+
+*   **The 1.57 Barrier**: The **Current Best Program**'s value of 1.57 at $n=1536$ remains the global benchmark. Even with resolution laddering to $n=2048$, the best results (**Gen 96**) only reach 1.58. This indicates that $n=1536$ is currently the optimal balance between the $2n$ multiplier in the objective function and the complexity of the optimization.
+*   **Success of Staged Escalation**: **Generation 90** achieved a score of -3.19 at $n=2048$ using staged resolution increases. While significantly worse than the 1.57 benchmark, it demonstrates that resolution escalation can maintain stability at high dimensions where other methods fail validation.
+*   **Stability of Binomial Seeds**: Every program that achieved a value below 1.60 (**Current Best, Gen 93, Gen 96**) utilized a binomial-derived initialization. Programs using U-shaped or other heuristics (**Gen 95, Gen 97, Gen 98**) typically plateau at a value of 2.00, suggesting that the binomial seed is essential for reaching the lower theoretical bound.
+*   **Impact of Budgeting**: High-performing programs consistently use a time-aware approach. The **Current Best Program** uses `total_elapsed` to scale both the softmax exponent and the spectral smoothing width, ensuring the strategy evolves from exploration to exploitation as the 10-second deadline approaches.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+Based on the success of the current best program and the analysis of the 1.57 convergence plateau, here are five actionable recommendations for future program mutations:
+
+1.  **Deterministic Symmetry Enforcement**: The current best program applies symmetrization stochastically. Evidence suggests the optimal sequence for this inequality is strictly symmetric. Enforce symmetry at every iteration by symmetrizing both the gradient (`grad = (grad + grad[::-1]) / 2`) and the sequence itself; this effectively halves the dimensionality of the search space, allowing Mirror Descent to converge much faster on high-resolution manifolds.
+
+2.  **Parabolic Step-Size Optimization**: Replace the discrete step-size search with a local quadratic fit to find the optimal learning rate. By evaluating the objective at three small step sizes (e.g., $0, \epsilon$, and $2\epsilon$), you can fit a parabola and jump directly to the predicted minimum. This precision is vital for "shaving" the final decimal points of the autoconvolution peaks when progress becomes extremely marginal.
+
+3.  **Resolution Laddering with Interpolation**: To break the 1.57 plateau, use a multi-stage approach: spend the first 30% of the budget at $n=768$ to rapidly find the global basin using the binomial sweep, then interpolate the sequence to $n=1536$ or $n=2048$ for high-precision refinement. This "warm start" prevents the optimizer from getting trapped in the local minima that frequently plague high-resolution starts while providing the degrees of freedom needed for a lower objective value.
+
+4.  **Exponential Softmax Cooling and Hard Thresholding**: Transition from a linear to an exponential schedule for the softmax exponent (e.g., $50 \cdot (1000/50)^t$) to focus the gradient more aggressively as time expires. In the final 15% of the time budget, introduce a "hard-threshold" where weights for all convolution indices below 99.9% of the current maximum are set to zero, forcing the gradient to exclusively target the absolute peaks.
+
+5.  **Momentum-Refined Gradient Smoothing**: Instead of periodic sequence smoothing, apply a constant Gaussian smoothing kernel (e.g., width 5 or 7) directly to the momentum-augmented gradient. This prevents the "jaggedness" or high-frequency oscillations introduced by aggressive multiplicative updates from ever being integrated into the sequence, maintaining the smooth, binomial-like curvature required for minimizing the $L_\infty$ norm of the autoconvolution.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Precise Binomial Parameter Sweeping**: Initializing with a binomial sequence derived from the family $(1-z)^{-k/2}$ remains the most reliable method for reaching the theoretical bound of $\pi/2 \approx 1.57$. The **Current Best Program (1.57 value)** and **Generation 107 (1.58 value)** both utilize a focused sweep of $k$ values (specifically 0.94 to 1.06) to find a high-quality basin before starting gradient descent.
+*   **Resolution Laddering (Upsampling)**: Progressively increasing the sequence length (e.g., from 768 to 2048) allows the optimizer to solve the coarse structure of the problem before refining high-frequency details. **Generation 101** achieved a value of 1.58 at $n=2048$ by laddering from 768, demonstrating that this technique can bridge the gap between low-resolution efficiency and high-resolution precision.
+*   **Momentum-Augmented Entropic Mirror Descent (EMD)**: Utilizing multiplicative updates ($seq \cdot e^{-\eta \cdot grad}$) paired with momentum (typically 0.75) is the primary engine for high-performance programs. This approach, used in the **Current Best Program** and **Generations 103 and 109**, ensures non-negativity and provides smoother convergence on the non-convex convolution landscape.
+*   **Softmax-Weighted Gradient Approximation**: To optimize the $L_\infty$ norm (max-convolution), successful programs approximate the gradient using a softmax-weighted sum of the convolution peaks. The **Current Best Program** uses an annealed exponent (50 to 1000) to transition from global smoothing to targeting the absolute maximum, while **Generation 101** uses this to prioritize "dominant peaks."
+
+## Ineffective Approaches
+
+*   **Fatal Implementation Omissions**: Despite sophisticated mathematical logic, **Generations 105, 106, and 108** all failed (score 0.0) due to basic Python errors: missing required library imports (`numpy`, `time`) or calling undefined helper functions (e.g., `_get_binomial`, `_fast_eval`). This highlights that modular logic requires strict inclusion of all dependencies within the execution block.
+*   **Inefficient Line Search Strategies**: **Generation 102** utilized a parabolic line search and achieved a poor value of 3.46. In contrast, the **Current Best Program** uses a "Granular Multiplicative Line Search" (testing 7 discrete step sizes like 0.0002 to 0.02), which is significantly more effective for the exponential update rules used in Mirror Descent.
+*   **Optimization Stagnation at Higher Resolutions**: Many programs targeting $n=2048$ directly (**Generations 100, 103**) plateaued at a value of 2.00. The increased search space complexity at $n=2048$ often prevents convergence within the 10-second budget unless preceded by a lower-resolution "laddering" phase or a highly accurate binomial seed.
+
+## Implementation Insights
+
+*   **Spectral Gradient Smoothing**: To prevent multiplicative updates from introducing high-frequency noise that spikes the max-convolution, the **Current Best Program** applies a 3-point Gaussian-like smoothing kernel to the gradient. It employs a "cooling" schedule for the kernel width (dropping from 0.15 to 0.05), allowing the optimizer to make finer adjustments as it nears the deadline.
+*   **Efficient Gradient Computation via Correlation**: The **Current Best Program** and **Generation 101** optimize computation by calculating the gradient using `np.correlate(weights, seq, mode='valid')`. This recognizes that the sensitivity of the convolution peak to a change in sequence elements is mathematically equivalent to the cross-correlation of peak weights with the sequence.
+*   **Symmetry as a Constraint**: **Generations 100, 101, 103, and 109** all enforce sequence symmetry ($a_i = a_{n-i-1}$). This effectively halves the dimensionality of the search space, which is critical for achieving stability when optimizing sequences of length 2048 within a limited time budget.
+*   **Scale-Invariant Normalization**: Since the objective function $2n \cdot \max(b) / (\sum a)^2$ is scale-invariant, the **Current Best Program** uses a `_normalize_scale` helper to keep the sum of the sequence equal to its length. This prevents numerical overflow or underflow during the exponential updates of Mirror Descent.
+
+## Performance Analysis
+
+*   **The 1.57 Benchmark**: The **Current Best Program** remains the leader with a value of 1.57 at $n=1536$. No program has yet surpassed this at $n=2048$, with the best $n=2048$ results (**Gen 101**) reaching 1.58. This suggests that $n=1536$ provides the optimal balance of resolution and optimization tractability for the current time budget.
+*   **Impact of Dimensionality**: There is a clear performance "tier" system: programs using binomial seeds and EMD typically fall between 1.57 and 1.60 (**Current Best, Gen 101, Gen 107**), while programs using standard Mirror Descent or laddering without precise sweeps often plateau at 2.00 (**Gen 100, 103, 109**).
+*   **Success of Hybrid Strategies**: The most successful recent programs (**Gen 101, 107**) combine **Resolution Laddering** with **Binomial Sweeping**. This hybrid approach allows the algorithm to find a global region of interest quickly and then refine it at higher resolutions, though the **Current Best**'s single-resolution (1536) high-intensity search still holds a slight edge.
+*   **Budget-Aware Parameter Scaling**: The **Current Best Program**'s use of `total_elapsed` to scale the softmax exponent and the spectral smoothing width ensures the optimizer transitions smoothly from exploration (smooth gradients, low exponent) to exploitation (sharp gradients targeting specific peaks) as time expires.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Strict Symmetry Enforcement at High Resolution**: While the current best program initializes with symmetric sequences and occasionally symmetrizes, evidence suggests the optimal solution is perfectly symmetric. Forcing symmetry at every iteration—by averaging the gradient with its reverse (`grad = (grad + grad[::-1]) / 2`) and the sequence itself—effectively halves the search space dimensionality. This reduction is critical for achieving faster convergence on the $n=1536$ or $n=2048$ manifolds within the tight 10-second budget.
+
+2. **Parabolic Step-Size Optimization**: Replace the current discrete "Granular Multiplicative Line Search" (testing 7 fixed steps) with a local quadratic fit. By evaluating the objective at three small relative step sizes (e.g., $0, \eta$, and $2\eta$), you can fit a parabola to the results and jump directly to the predicted minimum. This precision is vital for "shaving" the final decimal points of the autoconvolution peaks when progress using discrete steps plateaus.
+
+3. **Resolution Laddering with Cubic Interpolation**: To improve the 1.57 benchmark, implement a two-stage "warm start" strategy. Spend the first 25% of the time budget at $n=768$ to rapidly find the global basin using the binomial sweep and high-speed Mirror Descent, then use cubic interpolation (`scipy.interpolate.interp1d`) to upsample the sequence to $n=1536$ or $2048$ for high-resolution refinement. This avoids the high-frequency local minima that often trap high-resolution starts while providing the degrees of freedom needed for a lower objective value.
+
+4. **Exponential Softmax Cooling and Hard Peak-Targeting**: Transition from a linear to an exponential schedule for the softmax exponent (e.g., scaling from 50 to 2000) to focus the gradient more aggressively on the absolute maximum of the convolution. In the final 10% of the time budget, introduce a "hard-threshold" where weights for all convolution indices below 99.5% of the current maximum are set to zero, forcing the optimizer to exclusively minimize the dominant peaks that define the $L_\infty$ norm.
+
+5. **Curvature-Aware Gradient Smoothing**: Synchronize the spectral smoothing kernel width with the softmax exponent schedule. As the exponent increases to target sharp peaks, the Gaussian smoothing kernel width should decrease (e.g., from 0.20 down to 0.01) to allow the sequence to develop the high-frequency features necessary to "fill" the gaps between peaks. This prevents the smoothing from fighting the optimization in the final exploitation phase while maintaining stability during the initial exploration.

+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+Based on the evaluation results of Generations 110–121 and the performance of the current best program, the following optimization insights have been extracted:
+
+### Successful Algorithmic Patterns
+
+*   **Precise Binomial Parameter Sweeping with Symmetry**: Initializing with the binomial family $(1-z)^{-k/2}$ remains the most robust strategy. The **Current Best Program (1.57 value)** and **Generation 113 (1.58 value)** both utilize a focused sweep of $k \in [0.94, 1.06]$. Generation 113 combined this with "deterministic symmetry," enforcing $a_i = a_{n-i-1}$ to halve the search space, which proved critical for achieving a 1.58 score at $n=2048$.
+*   **Resolution Laddering (Upsampling)**: Progressively increasing sequence length (e.g., from 1024 to 2048) allows the optimizer to resolve coarse structures efficiently before fine-tuning high-frequency details. This was the central theme of successful programs in this cohort: **Generations 112, 113, 119, and 121** all reached the 2.00 threshold or better using laddering, with **Gen 113** achieving the best results at $n=2048$ (1.58).
+*   **Momentum-Augmented Entropic Mirror Descent (EMD)**: Multiplicative updates ($seq \cdot e^{-\eta \cdot grad}$) are more effective than additive updates for maintaining non-negativity and navigating the convolution landscape. The **Current Best Program** and **Gen 113** use this with momentum (0.75), which prevents the optimization from oscillating near the sharp peaks of the $L_\infty$ norm.
+*   **Softmax-Weighted Gradient Approximation**: To optimize the max-convolution (a non-differentiable objective), successful programs approximate the gradient using a softmax-weighted sum of all convolution results. The **Current Best Program** uses an annealed exponent (scaling from 50 to 1000) to shift focus from global smoothing to targeting the absolute maximum peak as the time budget expires.
+
+### Ineffective Approaches
+
+*   **Fatal Library Scope Errors**: Despite sophisticated logic, **Generations 110, 114, 116, and 117** all failed (score 0.0) due to missing `import numpy as np` or `import time` within the execution block. This underscores that all dependencies must be explicitly included in every generation regardless of perceived complexity.
+*   **Static/Hardcoded Sequence Lengths**: **Generations 111 and 114** failed validation because they used fixed lengths (e.g., 768, 1536, or 2048) without adapting to the specific length $n$ required by the environment's evaluation call. Even if a program uses laddering, the final output must match the requested $n$.
+*   **Complex Search Strategies vs. Budget Constraints**: **Generation 116** attempted a "Parabolic Line Search," and **Generation 115** used "Spectral Mutations." Both failed to pass validation or time-out tests. In contrast, the **Current Best Program** uses a "Granular Multiplicative Line Search" (testing ~7 discrete step sizes), which provides a better balance of precision and speed.
+
+### Implementation Insights
+
+*   **Spectral Gradient Smoothing**: The **Current Best Program** applies a 3-point Gaussian-like smoothing kernel to the gradient. By "cooling" the kernel width (dropping from 0.15 to 0.05), it allows for broad structural changes early and high-resolution adjustments late in the run.
+*   **Efficient Gradient Computation via Cross-Correlation**: The most performant programs compute the gradient by correlating the peak weights with the sequence (`np.correlate(weights, seq, mode='valid')`). This is a mathematically efficient way to determine how a change in any element $a_i$ affects the sum of weighted convolution peaks.
+*   **Symmetry as a Constraint**: Programs reaching the 2.00 threshold (Gens 112, 119, 121) all enforced sequence symmetry at every step. This effectively reduces the dimensionality of the search space for $n=2048$ from 2048 to 1024, significantly accelerating convergence within the 10-second budget.
+*   **Scale-Invariant Normalization**: Since the objective is scale-invariant, the **Current Best Program** and **Gen 113** use a normalization helper to keep $\sum a_i = n$. This prevents numerical overflow/underflow when using exponential (multiplicative) updates.
+
+### Performance Analysis
+
+*   **The Resolution/Precision Trade-off**: The **Current Best Program** holds the lead (1.57) at $n=1536$. While **Generation 113** successfully utilized laddering to reach $n=2048$ with a score of 1.58, the slightly lower resolution of 1536 currently allows for more optimization iterations within the time limit, leading to better final values.
+*   **Laddering Convergence Tiers**: There is a clear performance tiering in recent evaluations. Basic laddering with symmetry reaches **2.00** (Gens 112, 119, 121). Adding a precise binomial sweep and momentum MD improves this to **1.58** (Gen 113). The best performance (1.57) is reached by further refining the MD with spectral smoothing and an annealed softmax exponent.
+*   **Stability of Binomial Seeds**: Across all successful programs, the binomial sequence remains the essential starting point. Every program that achieved a score $\le 2.00$ initialized with a variation of the binomial sequence, confirming that the basin of the optimal solution is consistently found near the $(1-z)^{-k/2}$ family.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Mandatory Symmetry Constraint at High Resolution**: The current best program only symmetrizes 5% of the time, yet the most successful high-resolution runs (Gens 113, 121) enforced symmetry throughout. Modify the Mirror Descent loop to explicitly average the gradient with its reverse (`grad = (grad + grad[::-1]) / 2`) and the sequence with its reverse at every iteration. This reduces the search space dimensionality from $n$ to $n/2$, which is critical for achieving a score below 1.57 within the 10-second budget at $n=1536$ or $n=2048$.
+
+2. **Two-Stage Multi-Resolution Laddering**: Implement a "warm-start" by spending the first 20% of the time budget optimizing at $n=512$ or $n=768$. Once the coarse global basin is found, upsample the sequence to $n=2048$ using `np.interp`. This allows the optimizer to rapidly establish the underlying binomial-like structure at low cost before using the remaining budget to fine-tune the high-frequency peaks that only emerge at higher resolutions.
+
+3. **Parabolic Line Search for Step-Size Optimization**: Replace the discrete 7-step "Granular Multiplicative Line Search" with a local quadratic fit. Evaluate the objective at three small relative step sizes (e.g., $0, \eta, 2\eta$), fit a parabola to the results, and jump directly to the predicted minimum. This precision is vital for "shaving" the final decimal points of the autoconvolution peaks when progress using discrete steps plateaus near the end of the budget.
+
+4. **Exponential Softmax Cooling with Hard-Peak Masking**: Transition from a linear to an exponential schedule for the softmax exponent (e.g., scaling from 50 to 2000) to more aggressively target the absolute maximum of the convolution. In the final 15% of the time budget, introduce a "hard-threshold" mask where weights for all convolution indices below 99.8% of the current maximum are set to zero, forcing the Mirror Descent to exclusively minimize the specific peaks that define the $L_\infty$ norm.
+
+5. **Curvature-Aware Smoothing Decay**: Synchronize the spectral smoothing kernel width with the softmax exponent schedule. Start with a broader Gaussian-like kernel (side weights of 0.20) to maintain sequence stability during early exploration, but decay these weights to zero (or a very small value like 0.01) as the softmax focus narrows. This prevents the smoothing operation from "fighting" the optimization during the final exploitation phase where high-frequency adjustments are needed to fill the gaps between peaks.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+### Successful Algorithmic Patterns
+
+*   **Resolution Laddering (Upsampling) for Convergence**: Progressively increasing sequence length (e.g., from 512 or 1024 up to 2048) consistently allows programs to reach the 2.00 threshold. This was the defining characteristic of **Generations 120, 123, 125, 126, and 128**, all of which achieved the optimal "Correct" status. By starting with lower-resolution sweeps, the optimizer establishes a robust global structure before refining high-frequency convolution peaks at $n=2048$.
+*   **Symmetry as a Search Space Reducer**: Strict symmetry enforcement ($a_i = a_{n-i-1}$) significantly improves convergence within the 10-second budget. **Generation 123 (Symmetric Entropic Mirror Descent)** and **Generation 125 (Symmetric Binomial MD)** reached 2.00 by utilizing symmetry to halve the number of free variables, effectively accelerating the search for the autoconvolution bottleneck.
+*   **Annealed Softmax Gradient Approximation (Current Best Program)**: The **Current Best Program (1.57 value)** utilizes an annealed softmax exponent that scales from 50.0 to 1000.0 over the runtime. This shifts the optimization focus from global smoothing early in the run to a sharp $L_\infty$ targeting of the absolute maximum convolution peak as the deadline approaches.
+*   **Precise Binomial Parameterization**: Every successful program (value $\le 2.00$) initialized with a variation of the binomial sequence $(1-z)^{-k/2}$. The **Current Best Program** and **Generation 113** specifically identify the $k \in [0.94, 1.06]$ range as the most productive starting basin for further local refinement.
+
+### Ineffective Approaches
+
+*   **Fatal Dependency Scoping**: Despite high algorithmic complexity, **Generation 129** and **Generation 127** failed (score 0.0) due to missing `import numpy as np` or `import time` within the executable block. This confirms that even advanced numerical strategies like "Parabolic Line Search" are neutralized by basic runtime environment errors.
+*   **Numerical Instability in Upsampling**: **Generation 124** failed validation despite using "progressive upsampling" and "soft-max gradients." Feedback suggests that upsampling (e.g., from 1024 to 1536) can introduce numerical instabilities or sequence length mismatches if not handled with robust normalization and boundary checks.
+*   **Empty Evolutionary Markers**: **Generation 122** failed immediately due to the absence of executable logic. This highlights that "placeholders" for spectral or laddering strategies do not provide any baseline for the evaluation framework.
+
+### Implementation Insights
+
+*   **Spectral Gradient Smoothing**: The **Current Best Program (1.57)** applies a Gaussian-like smoothing kernel to the gradient that "cools" over time (width dropping from 0.15 to 0.05). This allows the optimizer to make broad structural adjustments in the first half of the budget while permitting high-resolution "peak shaving" in the final stages.
+*   **Scale-Invariant Normalization**: Successful programs maintain stability by normalizing the sequence such that $\sum a_i = n$. The **Current Best Program** and **Generation 128** use normalization helpers to prevent the exponential updates of Mirror Descent from causing numerical overflow while preserving the scale-invariant nature of the objective function.
+*   **Multiplicative vs. Additive Updates**: Mirror Descent with multiplicative updates ($seq \cdot e^{-\eta \cdot grad}$) is superior to standard gradient descent. This is evident in the **Current Best Program**, which uses a "Granular Multiplicative Line Search" (testing step sizes from 0.0002 to 0.02) to maintain sequence non-negativity and navigate the sharp ridges of the convolution landscape.
+*   **Efficient Correlation-Based Gradients**: High-performing programs compute gradients by correlating the peak weights with the sequence (`np.correlate(weights, seq, mode='valid')`). This provides a mathematically exact and computationally efficient way to determine how individual sequence elements contribute to the maximum convolution peaks.
+
+### Performance Analysis
+
+*   **The Resolution-Value Trade-off**: While **Generations 120, 123, 125, 126, and 128** all hit the 2.00 mark at $n=2048$ using resolution laddering, the **Current Best Program** achieved a significantly better 1.57 score at $n=1536$. This indicates that for a fixed 10-second budget, optimizing a slightly shorter sequence (1536 vs 2048) allows for more iterations and finer convergence, yielding a better overall objective value.
+*   **Laddering Convergence Tiers**: There is a clear performance "floor" at 2.00 for programs using standard laddering and symmetry. Breaking below this threshold (to the 1.57 - 1.58 range) requires the addition of momentum-augmented Mirror Descent, spectral smoothing, and the annealed softmax gradient approximation found in the **Current Best Program**.
+*   **Reliability of Binomial Seeds**: Across the entire cohort, no program achieved a score $\le 2.00$ without using binomial initialization. Programs that attempted to start from "Empty Evolutionary Blocks" or "U-shape seeds" without binomial refinement failed to match the performance of the $(1-z)^{-k/2}$ family.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Three-Stage Resolution Laddering to $n=2048$**: While the current best program achieved 1.57 at $n=1536$, the global insights show that $n=2048$ is the target for the most robust results. Implement a laddering schedule that spends 15% of the budget at $n=512$, 25% at $n=1024$, and the remainder at $n=2048$, using `np.interp` for upsampling. This allows the optimizer to solve the "coarse" binomial structure quickly before spending the majority of the time budget on the high-dimensional $n=2048$ landscape.
+
+2. **Mandatory Symmetry Constraint for High-Resolution Convergence**: The current best program only symmetrizes 5% of the time, but successful $n=2048$ runs (Gens 123, 125) suggest that reducing the search space is critical at high resolution. Modify the Mirror Descent loop to explicitly enforce symmetry at every iteration by averaging the sequence and its reverse (`seq = (seq + seq[::-1]) / 2.0`) and doing the same for the gradient. This halves the number of free variables, effectively doubling the optimization speed within the fixed 10-second budget.
+
+3. **Parabolic Line Search for Precise Peak Shaving**: Replace the discrete 7-step "Granular Multiplicative Line Search" with a local quadratic fit to more accurately find the optimal step size. Evaluate the objective at three small relative step sizes (e.g., $0, \eta, 2\eta$), fit a parabola to the objective values, and jump to the vertex. This precision is vital for minimizing the $L_\infty$ norm of the convolution when progress typically plateaus using fixed or discrete step sizes.
+
+4. **Hard-Peak Masking in the Final Optimization Phase**: In the final 20% of the time budget, transition from the annealed softmax gradient to a "hard-threshold" mask. Instead of weighting all convolution indices, set the weights to zero for all indices whose values are less than 99.8% of the current maximum. This forces the Mirror Descent to exclusively focus its updates on the specific peaks that define the objective value, preventing "drift" in the rest of the sequence profile.
+
+5. **Nesterov-style Acceleration for Mirror Descent**: Upgrade the simple momentum ($0.75$) to a Nesterov-style accelerated gradient update. Calculate the gradient at the "looked-ahead" sequence position (`best_seq + momentum * velocity`) rather than the current position. This improvement helps the optimizer navigate the narrow, sharp ridges of the autoconvolution landscape more efficiently, which is essential as the softmax exponent increases and the gradient becomes more volatile.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Annealed Softmax Gradient for Peak Shaving**: The most successful programs (**Generation 131, 132, and the Current Best Program**) utilize an annealed softmax exponent (shifting from ~50.0 to 1000.0). This allows the optimizer to transition from global structural adjustments to high-intensity targeting of the absolute convolution maximum (the $L_\infty$ bottleneck). Programs using this technique consistently reached the **1.57** objective value.
+*   **Theoretically-Grounded Binomial Seeding**: Every high-performing program utilizes a sweep of binomial coefficients based on $(1-z)^{-k/2}$, specifically targeting the $k \in [0.94, 1.06]$ range. The **Current Best Program** and **Generation 139** use a precise 41-step sweep of this parameter, which acts as a "theoretical anchor" for the 1.57 limit, providing a much more robust starting point than random or uniform seeds.
+*   **Spectral Gradient Smoothing with Cooling**: To maintain the integrity of the sequence profile while performing high-resolution optimization, the **Current Best Program** and **Generation 132** apply Gaussian-like smoothing to the gradient. The smoothing kernel "cools" (e.g., width dropping from 0.15 to 0.05) over the budget, allowing for broader adjustments early and fine-grained "peak shaving" as the deadline approaches.
+*   **Momentum-Augmented Entropic Mirror Descent**: Integrating momentum (typically $\beta=0.75$) with multiplicative Mirror Descent updates has proven more effective than standard gradient descent. This combination, used in **Generations 131, 133, and 139**, helps navigate the sharp ridges of the convolution landscape without falling into local minima or oscillating.
+
+## Ineffective Approaches
+
+*   **Overshooting Resolution vs. Budget**: While resolution laddering up to $n=2048$ is theoretically superior, programs like **Generation 133, 134, and 137** achieved scores of only **1.75 to 2.00** at this resolution. In contrast, the **Current Best Program** achieved **1.57 at $n=1536$**. This suggests that within a 10-second budget, $n=2048$ may leave insufficient time for the iterative Mirror Descent to converge, whereas $n=1536$ strikes a better balance.
+*   **Fatal Dependency Scoping**: Even sophisticated algorithmic approaches fail entirely if basic environment management is neglected. **Generation 138** (Spectral Mirror Descent v2) failed with a score of **0.0** simply because it missed essential `import numpy` and `import time` statements within the executable block.
+*   **Inefficient Peak Suppression**: **Generation 135** (Ladder Mirror Symmetrizer) failed validation despite using "peak sharpening." This indicates that if the multiplicative update logic is not precisely tuned to the scale-invariant objective constraints (e.g., proper normalization or gradient derivation), the optimizer can deviate into invalid or high-objective regions.
+
+## Implementation Insights
+
+*   **Granular Multiplicative Line Search**: The **Current Best Program** implements a search over a specific set of small step sizes `[0.0002, 0.0005, 0.001, 0.002, 0.005, 0.01, 0.02]` using multiplicative updates (`seq * exp(-step * velocity)`). This ensures non-negativity and allows the program to make the largest possible safe step toward the convolution bottleneck in every iteration.
+*   **Efficient Gradient Calculation via Correlation**: High-performing programs calculate gradients by correlating the softmax-weighted peak locations with the sequence itself (`np.correlate(weights, best_seq, mode='valid')`). This provides a computationally efficient way to identify which sequence elements contribute most to the convolution peaks, facilitating targeted reduction.
+*   **Periodic Stability Mutations**: The **Current Best Program** incorporates low-probability (5%) mutations, including symmetrization and power transforms. These mutations act as a regularizer, preventing the sequence from becoming too "jagged" or numerically unstable during the aggressive Mirror Descent iterations.
+*   **Symmetry as a Complexity Reducer**: **Generations 130, 133, and 137** highlight that enforcing strict symmetry ($a_i = a_{n-i-1}$) significantly reduces search space complexity. While the **Current Best Program** uses symmetry as a starting point and a potential mutation, it prioritizes the spectral descent to reach the 1.57 threshold.
+
+## Performance Analysis
+
+*   **The 1.57 Convergence Floor**: There is a clear performance tier at **1.57**. Programs achieving this (**Gen 131, 132, 139**) all share the combination of binomial seeding, momentum mirror descent, and softmax peak weighting. This suggests 1.57 is a local (or global) minimum for the $(1-z)^{-k/2}$ family of sequences that is consistently reachable with these techniques.
+*   **The 2.00 Plateau for Standard Laddering**: Programs that rely primarily on resolution laddering and symmetry without advanced spectral smoothing or annealed gradients (e.g., **Gen 130, 133, 137**) consistently plateau at an objective value of **2.00**. This demonstrates that while laddering provides a good baseline, it is insufficient to reach the optimal 1.57 range on its own.
+*   **Resolution-Time Trade-off**: Analyzing **Generation 136** (1.59 at $n=2048$) vs. **Generation 139** (1.57 at $n=1536$) reveals that increasing resolution beyond 1536 offers diminishing returns under a 10-second limit. The extra iterations possible at $n=1536$ yield a more optimized sequence than the higher-resolution but less-refined $n=2048$ output.
+*   **Success of Hybrid Initializations**: The shift from purely random or uniform starts to hybrid "Binomial + Local Search" has moved the average successful program score from ~3.0-4.0 in earlier generations to the 1.57-2.00 range. All "Correct" programs in this cohort utilized binomial seeds.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Multi-Stage Resolution Laddering to $n=2048$**: The current best program reaches the 1.57 threshold at $n=1536$, but theory suggests $n=2048$ is the ceiling for the most competitive results. Implement a three-stage schedule (e.g., $n=512$ for 1.5s, $n=1024$ for 2.5s, $n=2048$ for 6s) using `np.interp` for upsampling to allow the Mirror Descent to converge on the coarse binomial structure quickly before performing high-resolution peak shaving.
+
+2. **Transition to Nesterov-Accelerated Mirror Descent**: Upgrade the simple 0.75 momentum to a Nesterov-style update by calculating the softmax gradient at a "look-ahead" sequence position (`best_seq + momentum * velocity`). This is particularly effective for navigating the narrow, sharp ridges of the convolution landscape that appear as the softmax exponent increases, preventing the oscillations that occur with standard momentum in the final optimization phase.
+
+3. **Enforce Structural Symmetry in Early Iterations**: Reduce the initial search space complexity by enforcing strict sequence symmetry ($a_i = a_{n-i-1}$) during the first 50% of the time budget. By averaging the sequence and its gradient with their mirrored versions, you effectively halve the number of free variables, which accelerates the discovery of the optimal binomial-like profile before allowing for asymmetric fine-tuning in the final stages.
+
+4. **Hard-Peak Gradient Masking in the Final Phase**: In the last 15% of the optimization budget, switch from the annealed softmax gradient to a "hard-mask" approach where gradient weights are set to zero for all convolution indices below 99.9% of the current maximum. This forces the Mirror Descent to focus its updates exclusively on the specific indices causing the $L_\infty$ bottleneck, preventing "profile drift" in non-peak areas from accidentally increasing the objective value.
+
+5. **Quadratic Approximation for Step-Size Selection**: Replace the discrete 7-step multiplicative line search with a local quadratic fit to determine the optimal step size. By evaluating the objective at three small relative steps (e.g., $\eta = 0, 0.001, 0.002$), the program can analytically find the vertex of the local parabolic approximation, leading to significantly more precise "peak shaving" than the current granular search.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Precision Binomial Sweeping as a Theoretical Anchor**: The most consistent path to the **1.57** objective value involves a dense sweep of binomial coefficients based on $(1-z)^{-k/2}$ for $k \in [0.94, 1.06]$. The **Current Best Program** and **Generations 144 and 147** use this initialization to bypass the stochastic search for a global structure, starting instead from a mathematically grounded near-optimum.
+*   **Cooling Spectral Gradient Smoothing**: To refine the sequence without introducing high-frequency noise, the **Current Best Program** employs a Gaussian-like smoothing kernel on the gradient that "cools" over time (width narrowing from 0.15 to 0.05). This allows the optimizer to perform broad structural shaping in the early budget phase and precise "peak shaving" on the convolution bottlenecks in the final seconds.
+*   **Momentum-Augmented Multiplicative Mirror Descent**: Utilizing an exponential map for updates (`seq * exp(-step * velocity)`) combined with momentum (typically $\beta=0.75$) has proven superior to standard additive gradients. This approach, seen in **Generation 147 (1.57)** and the **Current Best Program (1.57)**, strictly preserves non-negativity while navigating the non-smooth $L_\infty$ landscape of the autoconvolution.
+*   **Annealed Softmax for Bottleneck Targeting**: Successful programs (e.g., **Generation 145, 147**) utilize an annealed softmax exponent (ranging from 50 to 1000) to transform the autoconvolution into a gradient signal. This focuses the optimization pressure specifically on the indices contributing to the maximum convolution peaks, which are the primary drivers of the objective function.
+
+## Ineffective Approaches
+
+*   **Instability in Adaptive Peak Weighting**: While targeting peaks is essential, aggressive "adaptive weighting" or "bottleneck masking" can lead to catastrophic failure. **Generation 142 (3.17)** and **Generation 146 (0.0)** attempted sophisticated gradient masking and adaptive exponentiation that likely introduced instabilities or invalid sequences, preventing them from reaching the 1.57-1.58 performance tier.
+*   **Interpolation Artifacts in Resolution Laddering**: Moving from low to high resolution (e.g., 1024 to 2048) often introduces artifacts. **Generation 146** failed validation specifically because the interpolation during the laddering process could not be rectified by the gradient descent within the time budget.
+*   **Diminishing Returns of $n=2048$**: Although the limit $n \to \infty$ is theoretically better, the 10-second time budget creates a trade-off. **Generation 139 and the Current Best Program** achieved **1.57** at $n=1536$, while many programs attempting $n=2048$ (**Generations 140, 141, 145**) plateaued at **1.58 or 1.59**. This indicates that the extra iterations possible at $n=1536$ are more valuable than the higher resolution of $n=2048$ under tight time constraints.
+
+## Implementation Insights
+
+*   **Granular Line Search for Convergence**: The **Current Best Program** implements a specific multiplicative line search across a fixed set of small step sizes `[0.0002, 0.0005, 0.001, 0.002, 0.005, 0.01, 0.02]`. This ensures that every iteration makes the maximum possible improvement without overstepping the narrow "ridges" of the convolution landscape.
+*   **Symmetry as a Regularizer, Not a Constraint**: While **Generations 148 and 149** enforced strict symmetry and reached **2.00**, the **Current Best Program** uses symmetrization as a low-probability (5%) mutation. This allows the optimizer to explore slightly asymmetric profiles that may offer lower objective values while still benefiting from the stability of symmetric structures.
+*   **Computational Efficiency via NumPy Correlation**: High-performing implementations like the **Current Best Program** calculate the gradient using `np.correlate(weights, seq, mode='valid')`. This is an efficient way to determine the sensitivity of the maximum convolution peak to individual sequence elements, which is critical when working with large $n$ (1536-2048) and limited time.
+
+## Performance Analysis
+
+*   **The 1.57 Convergence Floor**: A clear performance ceiling exists at **1.57**. This score is consistently reached only by programs combining binomial seeding, momentum-augmented mirror descent, and fine-tuned gradient smoothing (**Generation 144, 147, and Current Best Program**).
+*   **The 2.00 Laddering Plateau**: Programs that rely on resolution laddering and symmetry but lack advanced spectral smoothing or precise binomial sweeps (**Generations 148, 149**) consistently plateau at **2.00**. This suggests that standard optimization techniques are insufficient to break into the 1.5x range without specific "peak shaving" mechanisms.
+*   **The Success of n=1536**: The data suggests that $n=1536$ is the current "sweet spot" for the 10-second budget. It provides enough resolution to approximate the $n \to \infty$ limit while allowing for a sufficient number of Mirror Descent iterations to reach the **1.57** floor, a feat that higher-resolution attempts at $n=2048$ often struggle to match within the same timeframe.
+*   **Initialization Sensitivity**: The jump from **3.17 (Gen 142)** to **1.57 (Gen 144)** demonstrates that even with similar Mirror Descent logic, the quality of the initial seed and the stability of the gradient calculation (e.g., avoiding over-aggressive peak weighting) are the primary determinants of success.

+The following are actionable recommendations for the next program generations:
+
+1. **Implement Three-Stage Resolution Laddering to $n=2048$**: While the current best uses $n=1536$, theory suggests $n=2048$ is superior if managed efficiently. Start at $n=768$ for the first 2 seconds to rapidly converge the global binomial structure, then upsample using `np.interp` to $n=1536$ for 4 seconds, and finally to $n=2048$ for high-resolution "peak shaving." This captures the computational speed of low-res and the theoretical floor of high-res.
+
+2. **Transition to Nesterov-Accelerated Multiplicative Updates**: Upgrade the 0.75 momentum to a Nesterov-style update by calculating the softmax gradient at a "look-ahead" sequence position (`best_seq * exp(-momentum * velocity)`). This is particularly effective for navigating the extremely narrow ridges of the convolution landscape that appear as the softmax exponent reaches 1000, preventing the oscillations seen in standard momentum.
+
+3. **Replace Discrete Line Search with Local Parabolic Approximation**: Instead of testing a fixed list of 7 step sizes, evaluate the objective at three small relative steps (e.g., $\eta = 0.0, 0.001, 0.002$). Use these three points to fit a local quadratic and analytically find the vertex; this provides a much more precise step size for the Mirror Descent, which is critical when trying to break the 1.57 convergence floor.
+
+4. **Dynamic Softmax Exponent linked to Convolution Sparsity**: Rather than a linear time-based ramp, calculate the "sharpness" of the convolution peaks (e.g., the ratio of the maximum to the mean) and use it to scale the softmax exponent. This ensures that the optimization pressure remains broad while the convolution is "lumpy" and only focuses on the extreme $L_\infty$ bottlenecks once the overall profile has been smoothed by the spectral gradient kernel.
+
+5. **Asymmetric Weighting for Tail-End Gradient Pressure**: Evidence suggests that the $L_\infty$ objective is highly sensitive to the decay rates at the sequence boundaries. Apply a "spatial" weight to the gradient that slightly amplifies updates at the indices $i \in [0, 0.05n]$ and $i \in [0.95n, n]$. This forces the Mirror Descent to more aggressively optimize the "tails" of the binomial distribution, which are often the primary drivers of autoconvolution peaks in the final stages.

+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Fixed-Resolution Optimization at $n=1536$ (The 1.57 Ceiling):** The **Current Best Program** maintains its lead with a score of **1.57** by optimizing directly at a sequence length of 1536. While multiple programs (**Generations 150, 152, 154, 155, 156, 157, 159**) utilized "Resolution Laddering" to reach $n=2048$, they all plateaued at **1.58**. This confirms that for a 10-second budget, the extra iterations available at $n=1536$ allow for finer "peak shaving" than the higher resolution of $n=2048$.
+*   **Binomial Sweep for Theoretical Initialization:** The most successful programs consistently start with a sweep of binomial sequences derived from $(1-z)^{-k/2}$. The **Current Best Program** uses a sweep of $k \in [0.94, 1.06]$, which provides the global structure necessary to reach the 1.5x range. Even programs that hit 1.58 (**Generations 152, 154, 159**) credit binomial initialization as their foundational starting point.
+*   **Dynamic Spectral Smoothing Kernels:** The **Current Best Program** utilizes a Gaussian-like smoothing kernel on the gradient that narrows (from width 0.15 down to 0.05) as the time budget elapses. This "cooling" effect allows the optimizer to handle broad structural shaping early on and switch to surgical refinements of the autoconvolution peaks in the final seconds. **Generations 154, 155, and 156** also adopted spectral smoothing to reach 1.58, demonstrating its necessity for stability in high-dimensional search.
+*   **Momentum-Augmented Entropic Mirror Descent:** The use of multiplicative updates (`seq * exp(-step * velocity)`) combined with Nesterov-style or standard momentum (typically $\beta=0.75$) remains the dominant strategy. This is seen in the **Current Best Program (1.57)** and was successfully implemented in **Generations 150, 154, and 157** to achieve 1.58.
+
+## Ineffective Approaches
+
+*   **The "Laddering Plateau" at 1.58:** A significant number of programs (**Generations 150, 152, 154, 155, 156, 157, 159**) implemented "Resolution Laddering"—starting optimization at a lower $n$ (e.g., 768 or 1024) and upsampling to 2048. While this approach is robust and consistently reaches **1.58**, it consistently fails to reach the **1.57** achieved by the fixed-resolution approach of the **Current Best Program**. This suggests that the interpolation step in laddering may introduce artifacts that require more time to "clean up" than the budget allows.
+*   **Instability in Multiplicative Updates:** **Generation 151** attempted a laddered Mirror Descent but failed validation (score 0.0). The feedback suggests that multiplicative updates can be unstable if the gradient-based landscape is not properly managed, potentially leading to sequence values that violate the implicit constraints of the objective.
+*   **Computational Overheads of Complexity:** **Generation 153** failed because of basic implementation errors (missing imports and length mismatches). This highlights a risk where increasing the complexity of the optimization logic (e.g., "two-stage optimization with generalized seeds") leads to bugs that are difficult to catch within the evolution cycle, whereas the **Current Best Program** maintains a streamlined, highly efficient loop.
+
+## Implementation Insights
+
+*   **Granular Line Search for Peak Control:** The **Current Best Program** uses a specific set of small step sizes `[0.0002, 0.0005, 0.001, 0.002, 0.005, 0.01, 0.02]` in a multiplicative line search. This allows the algorithm to perform "precise peak shaving" on the convolution bottlenecks, which is the key to moving from 1.58 down to 1.57.
+*   **Softmax Proxy for Max-Convolution:** High-performing programs (**Gen 154, 157, 159, and the Current Best**) all use an annealed softmax (exponent ranging from 50 to 1000) to create a differentiable proxy for the `max()` operator. This focuses optimization pressure on the indices that actually contribute to the objective value.
+*   **Symmetry as a Soft Constraint:** While some programs explicitly enforce symmetry to reduce the search space, the **Current Best Program** uses symmetrization as a rare mutation (5% probability). This allows the optimizer to explore asymmetric profiles that might offer marginal gains over strictly symmetric ones, while still benefiting from the stability of the binomial base.
+*   **Efficient Gradient Calculation:** Successful programs utilize `np.correlate` or `np.convolve` to compute gradients. This efficiency is critical; for $n=1536$ or $n=2048$, the number of iterations performed within 10 seconds directly correlates with the ability to minimize the maximum convolution value.
+
+## Performance Analysis
+
+*   **Convergence Stability:** There is a very strong convergence around the **1.58** score for any program using a combination of binomial seeds and Mirror Descent (7 out of 10 programs in this batch). Breaking this 1.58 barrier to reach **1.57** requires the specific refinements found in the **Current Best Program**, such as the cooling spectral kernel and the direct $n=1536$ approach.
+*   **Resolution vs. Iteration Count:** The data suggests a clear trade-off. Programs targeting $n=2048$ (**Gen 150, 152, 154, 155, 156, 157, 159**) are computationally more expensive per iteration. The **Current Best Program** at $n=1536$ reaches a better score (**1.57**), suggesting that the benefit of higher resolution is outweighed by the loss of optimization iterations within the 10-second window.
+*   **Robustness of Binomial Seeds:** Every program that achieved a score of 1.58 or better utilized some form of binomial initialization. Programs that omit this (seen in earlier generations) rarely break the 2.00 plateau, confirming that the global structure of $(1-z)^{-k/2}$ is essential for this specific mathematical inequality.
+*   **Validation Failures:** The 20% failure rate in this batch (**Gen 151, 153**) indicates that as the "laddering" and "multi-stage" logic becomes more complex, the risk of technical failures (instability, import errors, or dimension mismatches) increases significantly.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Replace Linear Interpolation with FFT-based Upsampling for Laddering**: The "1.58 plateau" observed in laddering programs likely stems from piecewise-linear artifacts introduced by `np.interp`, which create high-frequency noise in the autoconvolution. Implement resolution transitions (e.g., $1024 \to 1536 \to 2048$) using FFT-based resampling (zero-padding in the frequency domain) to preserve the spectral smoothness of the binomial base and allow the $n=2048$ resolution to finally surpass the $n=1536$ fixed-resolution results.
+
+2. **Transition to Nesterov-Accelerated Mirror Descent**: Upgrade the current momentum implementation to a Nesterov-style update by calculating the softmax gradient at a "look-ahead" sequence position (e.g., `best_seq * np.exp(-momentum * velocity)`). This is specifically designed to handle the extremely narrow, high-curvature ridges that appear in the $L_\infty$ landscape as the softmax exponent approaches 1000, preventing the oscillations that limit the current 1.57 best.
+
+3. **Implement Local Parabolic Line Search for Peak Shaving**: Instead of the current fixed-list multiplicative line search (7 discrete steps), evaluate the objective at three small relative step sizes (e.g., $0, \eta, 2\eta$). Use these points to fit a local quadratic and analytically solve for the vertex to find the optimal $\eta$; this provides the surgical precision required to "shave" the final $0.01$ off the score during the last 2 seconds of the budget.
+
+4. **Apply Spatial Gradient Weighting to Sequence Boundaries**: Evidence suggests the $L_\infty$ objective is highly sensitive to the decay rate at the sequence edges. Implement a "spatial mask" that amplifies the gradient updates at the first and last 5% of the sequence indices by a factor of 1.2–1.5; this forces the Mirror Descent to more aggressively optimize the "tails" of the distribution, which are often the hidden drivers of autoconvolution bottlenecks.
+
+5. **Dynamic Softmax Scaling based on Peak Ratio**: Rather than a linear time-based ramp for the softmax exponent (50 to 1000), scale the exponent based on the "sharpness" of the convolution peaks (e.g., $\max(c) / \text{mean}(c)$). This ensures the optimizer maintains a broad structural focus while the convolution is "lumpy" and only shifts to a "hard" max-proxy once the global profile is sufficiently flat, preventing premature convergence to local minima.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Fixed-Resolution Dominance at $n=1536$:** While resolution laddering has been used to reach $n=2048$, the most consistent path to the current best score of **1.57** involves direct optimization at $n=1536$ (**Generations 161, 166, 167, 168**). The **Current Best Program** targets $n=1536$ to maximize the number of optimization iterations within the 10-second budget, allowing for more "peak shaving" than higher-resolution attempts.
+*   **Momentum-Augmented Entropic Mirror Descent:** The use of multiplicative updates (`best_seq * np.exp(-step_size * velocity)`) combined with Nesterov-style momentum remains the superior optimization framework for this non-negative problem. This approach, used in the **Current Best Program** and **Generations 161, 162, 164, 166, and 168**, ensures non-negativity naturally while efficiently navigating the high-dimensional landscape.
+*   **Cooling Spectral Gradient Smoothing:** The **Current Best Program** employs a Gaussian-like smoothing kernel on the gradient that "cools" over time (narrowing from a width of 0.15 to 0.05). This strategy allows the optimizer to perform broad structural shaping in the early phase and surgical refinement of autoconvolution peaks in the final seconds, contributing to the **1.57** score.
+*   **Targeted Binomial Sweep ($k \approx 1.0$):** All programs hitting the **1.57** mark (**Generations 161-168**) initialize with a sweep of binomial sequences $(1-z)^{-k/2}$. The **Current Best Program** specifically sweeps $k \in [0.94, 1.06]$, which provides the mathematically grounded "U-shape" necessary to minimize the max-convolution objective.
+
+## Ineffective Approaches
+
+*   **Resolution Laddering Overhead:** Despite some success in reaching **1.57** with laddering (**Generations 162, 164**), other attempts at resolution scaling led to significantly worse results. **Generation 163** (Adam + FFT upsampling) only achieved **2.00**, **Generation 169** hit **2.19**, and **Generation 165** reached **2.51**. This confirms that the computational cost of upsampling and the time required to "clean up" interpolation artifacts often outweigh the benefits of higher resolution within strict time limits.
+*   **Standard Adam Optimization:** **Generation 163** attempted to use Adam on log-coefficients but only achieved a score of **2.00**. This suggests that standard momentum-based Mirror Descent is better suited for this specific objective function than Adam's adaptive learning rates, likely because the latter may struggle with the specific curvature of autoconvolution peaks.
+*   **Over-Engineering Complexity:** **Generation 160** failed entirely despite using "sophisticated techniques" like softmax-weighted peak optimization and multi-resolution upsampling. This highlights the risk of complex implementations failing validation or stability checks, whereas the **Current Best Program** uses a streamlined, stable loop.
+
+## Implementation Insights
+
+*   **Granular Multiplicative Line Search:** The **Current Best Program** utilizes a specific set of small, predefined step sizes `[0.0002, 0.0005, 0.001, 0.002, 0.005, 0.01, 0.02]` in its line search. This allows for precise "shaving" of the convolution peaks, which is the critical operation for moving from the 1.58 plateau down to **1.57**.
+*   **Softmax Cooling/Annealing:** High-performing programs (**Current Best, Generation 162, 169**) use an annealed softmax proxy for the `max()` operator. By increasing the exponent (e.g., from 50 to 1000 in the **Current Best Program**), the gradient becomes increasingly focused on the exact indices of the highest convolution peaks as the search progresses.
+*   **Symmetry as an Occasional Mutation:** The **Current Best Program** does not strictly enforce symmetry in every iteration; instead, it uses symmetrization as a rare mutation (15% of the 5% mutation chance). This allows the optimizer to explore slightly asymmetric profiles that may offer marginal improvements while still utilizing the stability of the symmetric binomial base.
+*   **FFT Resampling for Laddering:** When resolution laddering is used, FFT-based resampling (**Generations 163, 165, 169**) is the preferred method for upsampling as it preserves the spectral integrity of the sequence better than linear interpolation, although it does not guarantee a score improvement over fixed-resolution $n=1536$.
+
+## Performance Analysis
+
+*   **The 1.57 Convergence:** There is a remarkably strong convergence at the **1.57** score across different generations (**161, 162, 164, 166, 167, 168**). This suggests that 1.57 is a significant local (or potentially global) optimum for sequences around $n=1536$ to $n=2048$ that can be reached within 10 seconds.
+*   **Sensitivity to Hyperparameters:** The difference between a **2.51** (Gen 165) and a **1.57** (Gen 161) often comes down to the optimization method (Mirror Descent vs. standard Descent) and the precision of the initialization sweep. Programs that skip the refined binomial sweep or use less targeted optimization consistently fail to break the 2.00 barrier.
+*   **Iteration Volume vs. Resolution:** Programs that targeted $n=1536$ were generally more successful in reaching the **1.57** score than those pushing to $n=2048$. The extra 33% increase in sequence length for $n=2048$ significantly increases the cost of both the convolution and the correlation in the gradient step, reducing the total number of refinements possible within the budget.
+*   **Stability of Multiplicative Updates:** The **Current Best Program** demonstrates that `np.exp(-step * velocity)` is exceptionally stable for maintaining non-negativity. Programs that failed or underperformed often lacked this specific multiplicative update structure or failed to properly normalize the sequence during the process.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Nesterov-Accelerated Mirror Descent**: Upgrade the standard momentum implementation to a Nesterov-style "look-ahead" update by calculating the softmax gradient at a predicted position (e.g., `best_seq * np.exp(-momentum * velocity)`). This approach is better suited for navigating the narrow, high-curvature ridges that emerge in the autoconvolution landscape as the softmax exponent increases, preventing the oscillations that currently stall refinement at the 1.57 mark.
+
+2. **Replace Discrete Line Search with Golden Section Search**: Instead of the fixed 7-step multiplicative list, implement a Golden Section Search to find the optimal step size $\eta$ within the range $[0.0001, 0.05]$. This provides the surgical precision required to find the exact minimum along the descent direction, which is critical for "peak shaving" during the final seconds of the optimization budget when discrete steps are too coarse.
+
+3. **Incorporate Late-Stage FFT-based Resolution Escalation**: Transition from $n=1536$ to $n=2048$ during the final 15% of the time budget using FFT-based upsampling (zero-padding in the frequency domain). FFT upsampling preserves the spectral integrity and smoothness of the binomial-derived profile better than linear interpolation, potentially allowing the optimizer to bypass the 1.57 plateau by refining the sequence at a higher resolution without introducing noise.
+
+4. **Dual-Track Symmetry Optimization**: Maintain two parallel sequences—one strictly symmetric and one allowed to be asymmetric—and optimize them simultaneously or via alternating iterations. Since the $(1-z)^{-k/2}$ anchor is symmetric, enforcing symmetry provides stability, while allowing controlled asymmetry in the "asymmetric track" can help the optimizer shave off persistent local peaks that a purely symmetric profile might be unable to resolve.
+
+5. **Adaptive Softmax Scaling Based on Peak Statistics**: Replace the linear time-based ramp for the softmax exponent ($50 \to 1000$) with a dynamic scaling factor based on the ratio of the maximum convolution peak to the mean ($m / \text{avg}(c)$). This ensures the gradient focus only sharpens once the global autoconvolution profile is sufficiently flat, preventing the optimizer from "locking in" on specific peaks prematurely before the broader structural U-shape is fully optimized.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Symmetrized Nesterov-style Mirror Descent:** The most successful programs (**Generations 170, 171, 172, 175, 176, 179**, and the **Current Best Program**) all utilize Mirror Descent with Nesterov momentum and multiplicative updates (`exp(-step * velocity)`). This approach ensures non-negativity while efficiently targeting the non-differentiable `max(convolve)` objective. Explicitly symmetrizing both the sequence profile and the gradient—as seen in the **Current Best Program** and **Generation 179**—consistently results in the top score of **1.57**.
+*   **Targeted Binomial and Power-Law Anchoring:** Initializing from theoretically-informed seeds, specifically binomial sequences $(1-z)^{-k/2}$ with $k \in [0.9, 1.1]$, provides a critical starting structure. The **Current Best Program** and **Generation 175** performed a sweep of these $k$ values to find an "anchor" sequence, which proved more effective than random initialization for sequences of length 1536 and 2048.
+*   **Annealed Softmax Peak Focusing:** High-performing programs replace the non-differentiable `max()` function with a softmax-weighted gradient. The **Current Best Program** utilizes an "exponent cooling" strategy, increasing the exponent from 100 to 900 over the optimization budget. This progressively narrows the gradient focus onto the highest autoconvolution peaks, enabling surgical "shaving" of those bottlenecks to reach the **1.57** plateau.
+*   **FFT-based Spectral Smoothing and Resampling:** Maintaining structural smoothness while transitioning between resolutions (e.g., $1536 \rightarrow 2048$) is vital. **Generations 170, 172, and 179** used FFT-based resampling or spectral smoothing kernels (like `[0.01, 0.98, 0.01]`) to prevent high-frequency noise from corrupting the autoconvolution profile during resolution escalation.
+
+## Ineffective Approaches
+
+*   **Unrefined Resolution Escalation:** While laddering can reach $n=2048$, it is often detrimental if not paired with smoothing. **Generations 177 and 178** implemented resolution escalation but only achieved scores of **3.45** and **3.53**, significantly worse than the **1.57** baseline. This indicates that poor interpolation or lack of post-upsampling refinement creates artifacts that the optimizer cannot overcome within the 10-second limit.
+*   **Low-Resolution Ceilings:** **Generation 173** utilized a progressive upsampling strategy but stopped at $n=1280$, resulting in a score of **2.00**. This confirms that the objective function $2n \cdot \max(B) / (\sum A)^2$ requires maximizing $n$ (reaching 1536 or 2048) while simultaneously minimizing peaks to achieve competitive results.
+*   **Missing Computational Safeguards:** **Generation 174** failed to pass validation despite using sophisticated mirror descent. This failure highlights that even mathematically sound models will fail if basic implementation details—such as required imports (`numpy`, `time`) or handling of computational time limits—are neglected.
+*   **Standard Additive Gradient Descent:** Consistent with previous insights, programs that rely on standard additive updates or Adam-style optimization (**Generation 163**) continue to underperform (2.00+) compared to the multiplicative mirror descent framework used in the **Current Best Program**.
+
+## Implementation Insights
+
+*   **Predictive Look-ahead (Nesterov Mirror Descent):** The **Current Best Program** implements a look-ahead step (`seq_look = normalize(curr_seq * exp(-momentum * velocity))`) to calculate gradients. This predictive mechanism allows the optimizer to anticipate the curvature of the autoconvolution landscape, leading to more stable convergence on sequences up to $n=2048$.
+*   **Gradient Correlation for Efficiency:** The gradient of the autoconvolution maximum with respect to the sequence coefficients is efficiently computed using `np.correlate(w_l, seq_look, mode='valid')`. This operation, utilized by the **Current Best Program**, is computationally cheaper than repeated convolutions and is the key to maintaining a high iteration count at $n=2048$.
+*   **Hybrid Stochastic/Deterministic Search:** The **Current Best Program** combines Mirror Descent with Simulated Annealing (Metropolis-Hastings acceptance). By including a temperature-based acceptance criteria (`temp = 1e-6 * (1 - progress)`), the program can escape local minima early in the search while settling into precise refinement in the final seconds.
+*   **Micro-Line Searches:** Rather than a fixed learning rate, the **Current Best Program** and **Generation 179** use micro-line searches (testing steps like `alpha * 0.5, alpha, alpha * 2.0`). This ensures every iteration effectively reduces the objective, which is critical for moving from the 1.58 plateau to the **1.57** mark.
+
+## Performance Analysis
+
+*   **The 1.57 Barrier at High Resolutions:** A significant number of programs (**Generations 170, 171, 172, 175, 176, 179**) reached the **1.57** evaluation value at sequence lengths of either 1536 or 2048. This suggests that the optimization has hit a structural limit for sequences of this type, where further improvement requires extremely fine control over the coefficient shape.
+*   **Sequence Length vs. Iteration Count:** While **Generation 170** reached 1.57 at $n=1536$, the **Current Best Program** and **Generation 179** achieved the same 1.57 at $n=2048$. The extra length provides a more favorable multiplier in the objective function ($2n$), but the increased computational cost of convolution at $n=2048$ reduces the number of possible iterations. The most successful programs balance this by using highly efficient correlation-based gradients.
+*   **Symmetry and Convergence:** Programs that strictly enforce symmetry (**Generation 176, 179**) or use it as a primary mutation (**Current Best Program**) show zero variance in their performance across runs (aux_std_dev 0.00). This confirms that the search space reduction provided by symmetry is essential for achieving consistent high-tier results within the 10-second budget.
+*   **Impact of Initialization:** Programs that skipped the binomial/power-law sweep and relied on random or flat initialization consistently failed to break the 2.00 barrier, proving that the objective's landscape is too complex for local search to find the optimal "U-shape" from scratch.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+Based on the successful optimization patterns and the current best program's performance at the 1.57 plateau, here are five actionable recommendations for future program mutations:
+
+1.  **Implement Closed-Loop Softmax Annealing**: Instead of the current time-based linear ramp ($100 \to 900$), adapt the softmax exponent based on the "flatness" of the autoconvolution profile. Calculate the ratio between the maximum peak and the 90th percentile of the convolution; increase the exponent sharply only when this ratio drops below a certain threshold (e.g., 1.05), ensuring the gradient focuses on fine-tuning only after the global U-shape is stable.
+
+2.  **Integrate Preconditioned Mirror Descent**: Use a diagonal approximation of the Hessian to scale the learning rate for each coefficient, similar to RMSProp or Adam but adapted for the multiplicative update. By tracking a moving average of the squared gradients (`cache = decay * cache + (1 - decay) * grad**2`), you can normalize the updates across the sequence, preventing the "edges" of the U-shape (which often have larger gradients) from dominating the refinement of the "center."
+
+3.  **Implement Fractional "Phase-Shift" Micro-Rolls**: Replace the discrete `np.roll` with a sub-pixel shift implemented via the Fourier Shift Theorem (multiplying the FFT of the sequence by $e^{-i 2\pi \delta f}$). Shifting the sequence by fractional amounts (e.g., 0.1 to 0.5 indices) can help align the autoconvolution peaks more precisely between discrete grid points, potentially lowering the maximum peak value that integer shifts cannot resolve.
+
+4.  **Multi-Stage Resolution Cascading with FFT Upsampling**: Transition through a formal resolution ladder ($n=512 \to 1024 \to 2048$) using spectral zero-padding (FFT upsampling) rather than linear interpolation. Spend 20% of the budget at each lower resolution to establish the macro-scale U-shape rapidly, and reserve the final 60% of the budget at $n=2048$ for high-precision Mirror Descent, as lower resolutions converge much faster to the 1.6-1.7 range.
+
+5.  **Controlled Late-Stage Symmetry Breaking**: After the optimizer reaches the 1.57 plateau using strict symmetry, introduce a "relaxation" phase in the final 10% of the time budget. Allow the sequence to become slightly asymmetric by reducing the weight of the symmetrization step (`seq = (1-eps)*seq + eps*seq[::-1]`, where `eps` decays from 1.0 to 0.95), which can allow the optimizer to "shave" specific persistent peaks that are structurally unavoidable in a perfectly symmetric profile.

+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Spectral Resolution Laddering with FFT Resampling:** The most successful programs in this cycle (**Generations 182, 184, 186, 187, and 188**) all utilized a strategy of optimizing at a lower resolution (e.g., 1024 or 1536) and then upsampling to $n=2048$ using FFT-based interpolation or `np.interp`. This "laddering" allows the optimizer to find a smooth global shape first before refining high-frequency details, consistently hitting the **1.57** evaluation plateau.
+*   **Symmetrized Nesterov Mirror Descent:** The **Current Best Program (Gen 188)** and **Generation 186** achieved a score of **1.57** by combining multiplicative mirror descent (`exp(-step * grad)`) with Nesterov-style momentum and explicit symmetry projection (`(seq + seq[::-1]) / 2`). Multiplicative updates are superior to additive ones because they naturally preserve the non-negativity of the sequence while allowing for exponential convergence on small coefficient values.
+*   **Annealed Softmax Peak Weighting:** Replacing the non-differentiable `max()` function with a softmax-weighted gradient focused on convolution peaks remains the dominant strategy. The **Current Best Program** uses an "exponent cooling" strategy, ramping the softmax temperature from 100 up to 900. This enables the optimizer to initially target several high peaks and eventually focus "surgically" on the single largest bottleneck peak to shave down the objective value.
+*   **Preconditioned Binomial Seeding:** Programs that performed a targeted sweep of binomial sequences $(1-x)^{-k/2}$ with $k \approx 1.0$ (e.g., **Gen 185, 187, 188**) consistently outperformed random initialization. The **Current Best Program** specifically tests $k$ in the range $[0.98, 1.02]$, which provides a nearly optimal "U-shape" that the mirror descent then refines.
+
+## Ineffective Approaches
+
+*   **Basic Implementation Failures (Imports and Logic):** Despite using sophisticated concepts like resolution laddering, **Generation 181** failed with a score of **0.0** due to missing `numpy` and `time` imports. Similarly, **Generation 189** failed all validation tests, likely due to a fundamental misalignment between the complex gradient logic (dynamic beta scheduling) and the actual objective function requirements.
+*   **Insufficient Resolution Targeting:** While **Generation 180** used high-quality techniques like entropic mirror descent and binomial initialization, it only targeted $n=1536$ and achieved a score of **2.33**. Comparing this to **Gen 182** (score **1.57** at $n=2048$) confirms that maximizing the sequence length to the 2048 limit is mathematically necessary to minimize the $2n \cdot \text{max}(B) / (\text{sum } A)^2$ objective.
+*   **Unstable Resolution Transitions:** Programs that attempted upsampling without subsequent refinement or smoothing kernels (like the `[0.05, 0.9, 0.05]` filter in the **Current Best Program**) tend to introduce high-frequency artifacts. These artifacts create artificial peaks in the autoconvolution that degrade the score, as seen in earlier generations that failed to reach the 1.57 mark.
+
+## Implementation Insights
+
+*   **Efficient Gradient Computation via Correlation:** The **Current Best Program** and **Gen 184** compute the gradient of the convolution maximum using `np.correlate(w_l, seq_look, mode='valid')`. This is significantly more efficient than re-calculating full convolutions, allowing for more iterations within the 10-second budget even at the $n=2048$ resolution.
+*   **Micro-Line Searches for Stability:** The **Current Best Program** implements a micro-line search, evaluating three potential step sizes (`alpha * 0.5, alpha, alpha * 2.0`) in each iteration. This prevents the "catastrophic divergence" often seen in mirror descent when the gradient becomes steep, ensuring steady progress toward the **1.57** value.
+*   **Hybrid Search (SA + Mirror Descent):** The integration of a Metropolis-Hastings acceptance criterion (Simulated Annealing) in **Generation 186** and the **Current Best Program** allows the search to escape local optima early in the run. By cooling the temperature (`temp = 1e-6 * (1 - progress)`), the program shifts from exploration to high-precision refinement in the final seconds.
+*   **Predictive Look-ahead:** The **Current Best Program** uses a "look-ahead" sequence (`seq_look`) for gradient calculation, which is a hallmark of Nesterov momentum. By calculating the gradient at the predicted next position rather than the current one, the optimizer accounts for the curvature of the autoconvolution landscape more effectively.
+
+## Performance Analysis
+
+*   **Convergence on the 1.57 Floor:** A cluster of programs (**Generations 182, 184, 186, 187, 188**) all achieved an evaluation value of **1.57** at $n=2048$. This suggests that for the given constraints, 1.57 represents a near-optimal structural limit for non-negative sequences. Success is now defined by the reliability (zero variance) and the ability to reach this value consistently within 10 seconds.
+*   **The Impact of Sequence Length:** There is a clear performance gap between $n=1536$ (best score **2.33** in **Gen 180**) and $n=2048$ (best score **1.57** in **Gen 182+**). This confirms that the $2n$ multiplier in the objective function heavily rewards larger $n$, provided the autoconvolution peaks can be kept proportionally low.
+*   **Robustness of Symmetrical Initialization:** Programs that enforced symmetry from the start or during the initialization sweep (**Gen 185, 188**) demonstrated much more stable convergence. The **Current Best Program** has an `aux_std_dev` of **0.00**, indicating that the combination of binomial seeding and symmetry projection removes almost all stochastic uncertainty from the optimization process.
+*   **Laddering Efficiency:** Programs that used resolution laddering (**Gen 182, 184**) reached the target score faster than those attempting to optimize $n=2048$ from a cold start. This suggests that the lower-resolution optimization acts as a powerful "preconditioner" for the high-resolution refinement.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+Based on the success of the current best program and the evolution of the 1.57 plateau, here are five actionable recommendations for future program mutations:
+
+1.  **Replace Linear Interpolation with FFT-based Upsampling**: Instead of using `np.interp` during resolution laddering, utilize spectral zero-padding (transforming the sequence to the frequency domain with `np.fft.rfft`, padding the high frequencies with zeros, and transforming back). Linear interpolation introduces high-frequency "kinks" that create artificial peaks in the autoconvolution; FFT upsampling preserves the smooth, band-limited nature of the optimal U-shape, providing a superior starting point for the final $n=2048$ refinement.
+
+2.  **Implement PAPR-Driven Dynamic Softmax**: Shift from a time-based linear ramp for the softmax exponent ($100 \to 900$) to one driven by the Peak-to-Average Power Ratio (PAPR) of the convolution. Calculate `exponent = base_exp * (max(conv) / mean(conv))`; this automatically sharpens the gradient focus only when the convolution profile is "flat" and contains multiple competing peaks, preventing the optimizer from over-correcting when a single dominant peak is already being addressed.
+
+3.  **Apply Spectral Gradient Filtering**: Apply a low-pass Gaussian filter to the computed gradient in the frequency domain before performing the multiplicative update. By dampening the high-frequency components of the gradient, you ensure that the Mirror Descent step prioritizes the low-frequency "U-shape" structure, which is the primary driver of the 1.57 score, and avoids introducing "jitter" that creates localized spikes in the autoconvolution.
+
+4.  **Integrate Multiplicative RMSProp/Adam Scaling**: Adapt the Mirror Descent update to include a second-moment tracker (like RMSProp) for each coefficient: `cache = decay * cache + (1 - decay) * grad**2`. Normalize the update by `step * grad / (np.sqrt(cache) + eps)`. This per-coefficient scaling prevents the large gradients at the sequence boundaries from drowning out the subtle adjustments needed in the sequence center, where the autoconvolution is most sensitive to small changes.
+
+5.  **Implement Late-Stage Stochastic Symmetry Relaxation**: After reaching a stable plateau with strict symmetry (e.g., at 90% of the budget), introduce a "symmetry relaxation" factor. Instead of forcing `seq = (seq + seq[::-1]) / 2`, use a weighted average `seq = (1-eta)*seq + eta*seq[::-1]` where `eta` slowly decays from 0.5 to 0.45. This allows the optimizer to "shave" specific, persistent peaks that may be structurally trapped by perfect symmetry, potentially breaking the 1.57 limit.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+# Detailed Program Evaluation Analysis
+
+## Successful Algorithmic Patterns
+
+*   **Convolution-Targeted Gradient Mutation:** The most effective strategy across all successful programs (**Generations 10, 11, 12**) is identifying the specific indices of the sequence that contribute to the maximum convolution peaks. By calculating a "gradient" where `grad[k]` is the sum of `seq[p - k]` for all peak indices `p`, and then reducing `seq[k]` proportional to this gradient (e.g., `seq *= (1.0 - 0.04 * grad / max_grad)`), the optimizer directly flattens the bottleneck of the objective function. This approach consistently achieved the top score of **1.57**.
+*   **Binomial and Power-Law Seed Initialization:** Starting the search from mathematically grounded distributions rather than random noise is critical. Programs reaching the **1.57** threshold (**Generations 10, 12**) utilized specialized "binomial seeds" (derived from $a_i = a_{i-1} \cdot \frac{2i-1}{2i}$) and power-law distributions. **Generation 18**, which used more generic geometric shapes (sines, ramps), only achieved a score of **1.79**, suggesting that the binomial distribution provides a superior starting basin for this specific inequality.
+*   **Multi-Resolution Upsampling (Interpolation):** The current best program and its successful predecessors (**Generations 10-12**) all employ a strategy of starting with low-resolution sequences (e.g., length 128 or 256) and progressively upsampling to the maximum length of **1024** using `np.interp`. This allows the algorithm to find a globally optimal "smooth" shape before refining the high-frequency components that minimize the final objective.
+*   **Weighted Mutation Mix:** The best performing programs (**Generations 10, 11, 12**) utilize a specific probability distribution for mutations: approximately 30-35% targeted gradient reduction, 30% block noise, and 15-20% element swapping/shuffling. This balance ensures the search explores new shapes while aggressively optimizing the current best candidate's peaks.
+
+## Ineffective Approaches
+
+*   **Missing Runtime Dependencies in Execution Blocks:** A significant number of sophisticated programs (**Generations 13, 14, 16, 17, 19**) failed with a score of **0.0** because they omitted essential library imports (`import numpy as np`, `import time`) within the scope of the executable code block. This indicates that even theoretically sound strategies (like the "Adaptive Stochastic Peak Reduction" in **Generation 17**) cannot be evaluated if the implementation is not self-contained.
+*   **Over-Reliance on Generic Geometric Shapes:** **Generation 18** attempted to use a wide variety of shapes (humps, sines, ramps) but resulted in a lower score (**1.79**) compared to the **1.57** achieved by programs focused on binomial/power-law seeds. This suggests that for the AC inequality, the global optimum is closer to specific asymptotic mathematical sequences than to general trigonometric or linear functions.
+*   **Hardcoded Constraints vs. Test Flexibility:** **Generation 16** failed with a **0.0** score partly due to a hardcoded target length of 1024, which likely conflicted with validation tests using different sequence lengths. Successful programs like the **Current Best (Generation 12)** use dynamic length handling and `candidate_lengths` to remain robust across different evaluation scenarios.
+
+## Implementation Insights
+
+*   **Scale-Invariant Normalization:** The current best program utilizes a `_normalize_scale` function that clips negative values and scales the sequence so that its sum equals its length (`sum(seq) == len(seq)`). While the objective function $2n \cdot \text{max}(B) / (\sum A)^2$ is theoretically scale-invariant, this implementation detail is vital for numerical stability during repeated `np.power` and gradient-based mutations.
+*   **Peak Thresholding:** In the most successful programs (**Generations 10, 11, 12**), the gradient calculation targets not just the single maximum peak, but all indices where the convolution is within 99% of the maximum (`c > 0.99 * max_c`). This "multi-peak" targeting prevents the optimization from oscillating between two nearly-equal peaks and leads to a more uniform flattening of the autocorrelation function.
+*   **Smoothing as a Regularizer:** Successive use of `(roll(seq, 1) + 2*seq + roll(seq, -1)) / 4.0` acts as a low-pass filter. The best programs (**Generations 10-12**) use this mutation sparingly (approx. 5-10% of the time) to prevent the sequence from becoming too "jagged," which typically increases the maximum convolution value.
+
+## Performance Analysis
+
+*   **Performance Plateau at 1.57:** Multiple generations (**10, 11, 12**) have converged on the score of **1.57** at sequence length **1024**. This suggests that the "Binomial + Gradient Peak Reduction" strategy is highly robust but may have reached a local or global limit for the current search space and budget.
+*   **Length-Performance Correlation:** There is a direct correlation between sequence length and the achieved value. **Generation 18**, which focused on length 1024, achieved 1.79, while earlier versions using smaller lengths (e.g., **Generation 4** at length 284 with a score of 1.67) showed that increasing $n$ is generally necessary to reach the 1.57 mark, provided the mutation strategy is sufficiently targeted.
+*   **Impact of Stochasticity:** Programs that failed to incorporate uphill moves or sufficient noise (like the subgradient descent in **Generation 8**, score 0.0) were outperformed by the hybrid stochastic-gradient approach in the **Current Best Program**. The stochastic element (block noise and shuffling) is essential for escaping the complex local minima of the $L_\infty$ norm of the convolution.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Implement Adaptive Learning Rate for Gradient Mutations:** The current multi-peak gradient reduction uses a fixed step size of 0.04. Replace this with a "line search" or "decaying learning rate" approach where the mutation is only accepted if it improves the objective, or the step size (alpha) is reduced by half whenever a move fails to produce an improvement, allowing the sequence to converge more precisely at the 1.57 plateau.
+
+2. **Parameterize the Binomial Seed Distribution:** The standard binomial sequence ($a_i = a_{i-1} \cdot \frac{2i-1}{2i}$) has been the most successful starting point. Extend this by parameterizing the seed as $a_i = a_{i-1} \cdot \frac{2i-k}{2i}$ where $k$ is sampled between 0.5 and 1.5, allowing the algorithm to explore a wider family of power-law decays that may yield better initial basins than the fixed mathematical identity.
+
+3. **Enforce Sequence Symmetry via Mirroring Mutations:** Since many optimal autocorrelation sequences are symmetric, introduce a mutation that enforces symmetry by replacing the sequence with its mirrored average: `(seq + seq[::-1]) / 2.0`. This reduces the search dimensionality and forces the gradient reduction to treat the "left" and "right" sides of the convolution peaks identically, which can stabilize the optimization.
+
+4. **Transition to a Simulated Annealing Acceptance Criterion:** The current "greedy" search logic only accepts improvements, which often leads to local optima at high sequence lengths. Implement a Metropolis-Hastings acceptance rule where a worse sequence is accepted with probability $P = \exp(-\Delta V / T)$, using a temperature $T$ that cools over the duration of the budget; this allows the sequence to "reorganize" its peak structure.
+
+5. **Incorporate Windowing Functions to Suppress Edge Artifacts:** Convolution results are highly sensitive to the values at the beginning and end of the sequence. Add a mutation that applies a Tukey or Hann window to the sequence, or specifically smooths the boundary elements ($a_0$ to $a_{n/10}$ and $a_{9n/10}$ to $a_{n-1}$), to prevent sharp edges from creating unnecessary secondary peaks in the autocorrelation function.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Symmetrized Resolution Laddering with FFT Interpolation:** The most effective programs (**Current Best**, **Generations 192, 196**) utilize a multi-stage approach, optimizing first at lower resolutions (e.g., 1024 or 1536) before upsampling to $n=2048$. Using `np.interp` combined with spectral smoothing (like the `[0.05, 0.9, 0.05]` kernel in the **Current Best**) allows the optimizer to establish a smooth global "U-shape" before refining high-frequency convolution peaks.
+*   **Binomial-Seed Parameter Sweeps:** Rather than random initialization, the top-performing programs (**Current Best**, **Generation 199**) perform a targeted sweep of binomial sequences $(1-x)^{-k/2}$ with $k$ values near 1.0 (specifically $0.98$ to $1.02$). This provides a mathematically robust starting point that is already close to the structural optimum for the autoconvolution objective, which is then refined via gradient descent.
+*   **Multiplicative Mirror Descent with Nesterov Momentum:** Incorporating multiplicative updates (`seq * exp(-lr * grad)`) instead of additive ones has proven critical for maintaining non-negativity and handling the wide dynamic range of coefficients. When paired with Nesterov-style predictive look-ahead (**Current Best**, **Generation 193**), this approach efficiently navigates the complex, non-convex landscape of the autoconvolution maximum.
+*   **Softmax-Weighted Gradient Targeting:** Replacing the non-differentiable `max()` with a softmax-weighted sum of the convolution peaks allows for precise gradient-based refinement. The **Current Best** program employs a "cooling" or "sharpening" schedule, increasing the softmax exponent from 100 to 900 over the run duration to focus the optimization on the most problematic peaks.
+
+## Ineffective Approaches
+
+*   **Execution Runtime Failures (Missing Imports):** A significant number of sophisticated programs (**Generations 191, 195, 198**) failed entirely (score 0.0) because they omitted basic `import numpy` or `import time` statements within the execution block. This highlights that even the most advanced mathematical logic is useless without fundamental coding hygiene in the standalone environment.
+*   **Aggressive Resolution Jumps Without Smoothing:** While laddering is effective, jumps that are too large or lack subsequent smoothing can introduce high-frequency artifacts. **Generation 197** attempted a ladder from 512 to 2048 but only achieved a score of **2.07**, significantly worse than the **1.57** achieved by programs using more gradual or smoothed transitions (like **Gen 192** and **196**).
+*   **Static Step Sizes in Mirror Descent:** Programs that do not implement adaptive step-size mechanisms (like the micro-line search in the **Current Best**) often suffer from "catastrophic divergence" where the sequence values explode or collapse to zero when the gradient becomes steep, resulting in poorer evaluation values (e.g., **Generation 194**'s score of **3.53**).
+
+## Implementation Insights
+
+*   **Efficiency via Correlation Gradients:** The **Current Best** and **Generation 193** optimize gradient calculation by using `np.correlate(weights, sequence, mode='valid')`. This identifies the contribution of each coefficient to the weighted convolution peaks without requiring the computation of the full Jacobian, significantly increasing the number of iterations possible within the 10-second budget.
+*   **Micro-Line Search for Stability:** The **Current Best** program implements a micro-line search at each step, evaluating `alpha * 0.5`, `alpha`, and `alpha * 2.0`. This ensures that the Mirror Descent step is always taking the most productive path, contributing to the **0.00 standard deviation** and high reliability seen in its performance metrics.
+*   **Symmetry Projection:** Explicitly enforcing sequence symmetry (`(seq + seq[::-1]) / 2`) at each iteration or during the look-ahead step (**Current Best**, **Generation 192**) effectively halves the search space and stabilizes the autoconvolution profile, as the optimal non-negative sequences for this problem are known to be largely symmetric.
+*   **PAPR-Driven Dynamic Sharpening:** **Generation 196** and **197** experimented with "PAPR-driven" (Peak-to-Average Power Ratio) adjustments to the gradient, attempting to use the sequence's own distribution to scale updates. While complex, the most successful version of this remains the softmax-weighted peak optimization used in the **Current Best**.
+
+## Performance Analysis
+
+*   **The 1.57 Convergence Floor:** There is a clear performance plateau at **1.57** (at $n=2048$). Multiple programs (**Generations 192, 196,** and the **Current Best**) hit this exact value. This suggests that the combination of binomial seeding and Nesterov Mirror Descent has effectively solved the structural requirements of the $n=2048$ sequence.
+*   **Sequence Length Impact:** There is a direct correlation between sequence length and the objective value $2n \cdot \text{max}(B) / (\text{sum } A)^2$. **Generation 190** achieved 1.57 at $n=1536$, but the majority of top scores are achieved at $n=2048$. The extra resolution allows for more gradual "tapering" of the sequence ends, which minimizes the autoconvolution peaks relative to the total sum.
+*   **Reliability vs. Complexity:** The **Current Best Program** demonstrates that reliability (zero variance) is achieved by replacing stochastic elements with a comprehensive initial sweep (the 9-point binomial sweep) followed by deterministic gradient refinement. Programs that relied too heavily on random mutations or simulated annealing alone (e.g., **Generation 197**) showed significantly higher (worse) evaluation values.
+*   **Optimization Efficiency:** Comparison between **Generation 194 (3.53)** and **Generation 192 (1.57)** shows that high-resolution optimization ($n=2048$) is only effective if the gradient correctly targets the convolution peaks. Simply using a high-resolution sequence without the focused softmax-weighted gradient results in much higher objective values.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+Based on the successful patterns identified in the 1.57 plateau and the logic of the current best program, here are five actionable recommendations for future program mutations:
+
+1.  **Replace Linear Interpolation with FFT-based Upsampling**: Instead of using `np.interp` for resolution laddering, implement spectral zero-padding by transforming the sequence to the frequency domain with `np.fft.rfft`, padding the high-frequency components with zeros, and transforming back. This prevents the high-frequency "kinks" introduced by linear interpolation, ensuring that the smooth, band-limited "U-shape" remains intact when transitioning to the final $n=2048$ resolution.
+
+2.  **Implement PAPR-Driven Dynamic Softmax Focusing**: Shift from a time-based linear ramp for the softmax exponent ($100 \to 900$) to an adaptive mechanism driven by the Peak-to-Average Power Ratio (PAPR) of the convolution profile. By scaling the exponent based on the ratio of `max(conv) / mean(conv)`, the optimizer can automatically sharpen its focus when a single dominant peak emerges and broaden its focus when multiple peaks compete, preventing premature convergence to local sub-optima.
+
+3.  **Integrate Multiplicative Adam/RMSProp Scaling**: Enhance the Nesterov Mirror Descent by adding a second-moment tracker (like RMSProp) to the multiplicative update: `cache = decay * cache + (1 - decay) * grad**2`. Normalizing the update by `step * grad / (np.sqrt(cache) + eps)` prevents the large gradients at the sequence boundaries from dominating the update, allowing for more precise, high-resolution adjustments in the sequence center where the autoconvolution is most sensitive.
+
+4.  **Apply Spectral Gradient Filtering**: Instead of the current 3-point spatial smoothing kernel, apply a low-pass Gaussian filter to the gradient in the frequency domain before the Mirror Descent update. This ensures that the updates primarily reinforce the low-frequency global structure that drives the 1.57 score, effectively "filtering out" high-frequency noise that could lead to the formation of new, unwanted autoconvolution spikes.
+
+5.  **Introduce Late-Stage Symmetry Relaxation**: While symmetry is a powerful constraint, the 1.57 plateau may represent a local minimum for perfectly symmetric sequences. In the final 10% of the execution budget, replace the strict `(seq + seq[::-1]) / 2` projection with a relaxed version, `(1-eta)*seq + eta*seq[::-1]` where `eta` decays from 0.5 to 0.48, allowing the optimizer to "shave" persistent peaks that cannot be suppressed under perfect symmetry.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Multi-Peak Gradient Targeting:** The most significant performance driver, seen in the **Current Best Program** and **Generations 22, 23, 24, and 27**, is a specialized gradient descent that targets all convolution peaks within a 99% threshold of the maximum. By calculating a "grad" where `grad[k]` is the sum of `seq[p - k]` for all peak indices `p`, and applying multiplicative reduction (e.g., `seq *= (1.0 - 0.04 * grad / max_grad)`), the algorithm flattens multiple bottlenecks simultaneously rather than oscillating between single peaks. This consistently leads to the best objective value of **1.57**.
+*   **Binomial Coefficient and Power-Law Seeding:** Starting from mathematically grounded shapes is far superior to random initialization. The **Current Best Program** and **Generation 27 (binomial_gradient_refiner)** utilize seeds derived from the expansion $(1-x)^{-1/2}$ (where $a_i \approx a_{i-1} \cdot \frac{2i-1}{2i}$) or $1/\sqrt{i}$. This initialization places the search within the basin of the theoretical $\pi/2$ limit, allowing the optimizer to focus on refinement rather than global shape discovery.
+*   **Progressive Multi-Resolution Upsampling:** Successful programs (**Current Best**, **Generation 22**) start searching at lower resolutions (e.g., $n=128$ or $n=256$) and use linear interpolation (`np.interp`) to transition to the target length of $1024$. This "coarse-to-fine" strategy allows the algorithm to optimize the global curvature of the sequence before fine-tuning the high-frequency components that minimize the final autoconvolution ratio.
+*   **Symmetry and Regularization:** **Generation 22** and **Generation 27** incorporated mirroring (enforcing sequence symmetry) and periodic smoothing (using a 1-2-1 weighted kernel). These techniques act as a regularizer, preventing the sequence from becoming "jagged," which typically results in higher convolution peaks.
+
+## Ineffective Approaches
+
+*   **Namespace and Import Failures:** A recurring catastrophic failure mode (seen in **Generations 20, 25, 26, 28, and 29**) is the omission of essential library imports (`import numpy as np`, `import time`) within the scope of the execution block. Despite having sophisticated peak-reduction logic, these programs achieved a score of **0.0** because they were non-functional in the evaluation environment.
+*   **Generic Geometric Initialization:** While **Generation 18** (from previous insights) used diverse shapes like sines and ramps, it only reached a score of **1.79**. Modern successful programs (**Current Best**) have replaced or augmented these with "binomial" and "chirp" seeds, indicating that generic trigonometric functions are less effective for the AC inequality task than specific asymptotic sequences.
+*   **Empty Implementation Blocks:** **Generation 21 (gradient_minimax_optimizer)** provided only markers without executable logic, resulting in an immediate **0.0** score. This highlights that the evolution process occasionally produces "hollow" mutations that must be discarded in favor of structurally complete logic.
+
+## Implementation Insights
+
+*   **Numerical Stability via Sum-Normalization:** The **Current Best Program** utilizes a `_normalize_scale` function that forces `sum(seq) == len(seq)`. While the AC inequality $2n \cdot \text{max}(B) / (\sum A)^2$ is scale-invariant, maintaining a constant sum prevents numerical overflow during multiplicative gradient updates and keeps the denominator of the objective function stable across varying sequence lengths.
+*   **Multi-Start Length Strategy:** The **Current Best Program** does not just optimize at $n=1024$; it evaluates candidates at $[128, 256, 512, 1024]$. This multi-start approach ensures that if a lower-length sequence provides a better structural foundation, it can be upsampled to 1024 to reach the final objective.
+*   **Stochastic/Gradient Hybridization:** The successful programs use a mutation mix (approx. 35% peak-gradient, 30% block noise, 20% shuffling). This combination allows for aggressive exploitation of the current shape via gradient descent while maintaining exploration through stochastic noise, which is critical for escaping local minima in $L_\infty$ optimization.
+
+## Performance Analysis
+
+*   **The 1.57 Convergence Plateau:** Multiple high-performing programs (**Current Best, Generations 22, 23, 24, 27**) have all converged exactly on a score of **1.57** for sequence length **1024**. This suggests that 1.57 (approximating $\pi/2$) is a significant numerical threshold for this problem and that the "Binomial + Peak Gradient" strategy is the current state-of-the-art approach for this budget.
+*   **Impact of Sequence Length:** There is a clear correlation between sequence length and performance. Programs reaching the 1.57 mark consistently do so at the maximum allowed length ($n=1024$), whereas earlier generations with shorter sequences (e.g., $n=284$ in **Generation 4**) were limited to scores around 1.67.
+*   **Success Rate of Targeted Mutations:** The transition from random mutation to "Multi-peak gradient reduction" (introduced in the **Current Best** and predecessors) directly corresponds to the jump from 1.7+ scores to the 1.57 plateau. Programs that target only the single maximum peak fail to reach this level of performance as efficiently as those targeting the 99% peak-set.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Dynamic Peak Targeting Threshold:** Instead of a static 99% threshold for identifying convolution peaks in the gradient descent step, use a dynamic threshold that scales with the search progress (e.g., `max_c - (max_c - mean_c) * 0.01`). This ensures that as the convolution profile flattens, the optimizer continues to focus only on the most significant bottlenecks rather than being diluted by an increasing number of sub-peaks that have already been sufficiently suppressed.
+
+2. **Symmetry-Enforcement Mutations:** Introduce a mutation that periodically forces the sequence to be perfectly symmetric using `seq = (seq + seq[::-1]) / 2.0`. Mathematical theory for optimal autoconvolution sequences often points toward symmetric or near-symmetric distributions; enforcing this reduces the search space dimensionality and prevents the gradient reduction from creating asymmetric oscillations that lead to higher peak values.
+
+3. **Adaptive Step-Size Line Search:** Replace the fixed 0.04 multiplier in the gradient mutation with a mini-line search. For each gradient update, evaluate the objective at three step sizes (e.g., 0.01, 0.04, 0.1) and select the best one, or implement a decay where the step size is halved whenever 50 iterations pass without an improvement. This is crucial for breaking the 1.57 plateau, where very fine adjustments are required to navigate the high-dimensional landscape.
+
+4. **Momentum-Augmented Gradients:** Incorporate a "momentum" term into the multi-peak gradient logic by storing the previous gradient direction: `velocity = 0.9 * velocity + 0.1 * current_grad`. Applying updates based on this velocity helps the optimizer "carry through" consistent descent directions and avoids the "zig-zagging" behavior that occurs when the optimizer oscillates between targeting different sets of peaks in successive iterations.
+
+5. **Spectral Smoothing via FFT:** Implement a mutation that applies a low-pass filter in the frequency domain (FFT -> zero out/attenuate high frequencies -> Inverse FFT). While the current program uses a 1-2-1 spatial smoother, spectral smoothing can more effectively eliminate high-frequency "jitter" across the entire sequence length simultaneously, which often causes the sharp, localized peaks in the convolution that limit the current best score.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Exponentially-Weighted Peak Gradient Descent:** The most sophisticated evolution of the peak-targeting strategy, as seen in the **Current Best Program (Generation 39)** and **Generation 34**, uses exponential weighting (`w = np.exp(100.0 * (c[p] - m) / m)`) to prioritize the absolute maximum of the convolution while still addressing nearby bottlenecks. This creates a smoother, more effective gradient than the binary 99%-threshold mask used in earlier generations (e.g., Gen 27), allowing for more precise flattening of the autoconvolution profile to the 1.57 limit.
+*   **Diverse Analytical Seeding (Binomial & U-Shape):** Starting with mathematically grounded distributions is critical. The **Current Best Program** and **Generations 30, 32, and 34-38** all utilize variants of the binomial distribution ($a_i \approx a_{i-1} \cdot \frac{2i-k}{2i}$) with $k$ values around 0.95 to 1.05. Additionally, the inclusion of "U-shaped" seeds (e.g., `((idx + 0.5) * (n_len - idx - 0.5))**-0.5`) in **Generation 39** and **Generation 34** provides alternative starting basins that are well-suited for the scale-invariant AC inequality.
+*   **Spectral (FFT) Smoothing and Filtering:** Integrating low-pass FFT filters to suppress high-frequency noise (seen in **Generations 35, 36, 38, and 39**) prevents the local search from stalling on "jagged" local minima. By zeroing out higher frequencies of the sequence during mutation, the algorithm maintains a smooth global curvature, which is essential for minimizing the maximum of the autoconvolution.
+*   **Multiplicative Exponential Updates:** Successful programs like the **Current Best (Gen 39)** and **Generation 35** have shifted from additive gradient updates to multiplicative ones (`seq * np.exp(-step * velocity)`). This approach naturally enforces the non-negativity constraint and provides more stable convergence in $L_\infty$ optimization problems where values can vary by orders of magnitude.
+
+## Ineffective Approaches
+
+*   **Omission of Core Library Imports:** Despite advancements in algorithmic logic, basic programming errors persist. **Generation 33 (spectral_momentum_optimizer)** failed entirely (score 0.0) because it did not include `import numpy as np` and `import time`, highlighting that even the most advanced momentum-based logic is useless without a functional environment.
+*   **Numerical Instability in Advanced Seeding:** **Generation 31 (momentum_peak_descent_with_symmetry)** failed validation. This suggests that while sophisticated seeds like arcsine distributions are theoretically interesting, they can lead to numerical instability or logic errors during initialization if not carefully constrained by safety checks.
+*   **Generic Multi-start Without Domain-Specific Seeds:** Programs that rely on generic trigonometric or random starts (alluded to in previous global insights and improved upon in **Gen 30-39**) consistently underperform compared to those utilizing binomial expansions. Generic seeds fail to place the search within the specific basin required to reach the $\pi/2 \approx 1.57$ plateau.
+
+## Implementation Insights
+
+*   **Adaptive Resolution and Upsampling:** The **Current Best Program** evaluates multiple sequence lengths (1024, 1152, 1280) and uses `np.interp` to transition between them. This allows the algorithm to discover a robust global shape at one resolution and refine the fine-grained details at a higher resolution, which is critical for reaching the 1.57 objective value.
+*   **Scale-Invariant Sum Normalization:** While the objective function is mathematically scale-invariant, the **Current Best Program** maintains numerical stability by forcing `sum(seq) == len(seq)`. This prevents floating-point overflow during the exponential weighting and multiplicative update phases of the gradient descent.
+*   **Momentum-Augmented Local Search:** The transition from simple gradient descent to momentum-based descent (velocity = $0.9 \cdot velocity + 0.1 \cdot grad$) in **Generations 31, 33, 34, 36, and 39** helps the optimizer navigate the "narrow valleys" of the convolution landscape, preventing oscillation between different peak indices.
+
+## Performance Analysis
+
+*   **The 1.57 Convergence Floor:** A significant cluster of programs (**Generations 30, 32, 34, 35, 36, 37, 38, and 39**) all achieved the identical objective value of **1.57**. This value (which approximates $\pi/2$) appears to be a global minimum or a very strong local attractor for this problem. Performance improvements are now measured by the efficiency/reliability of reaching this floor rather than surpassing it.
+*   **Correlation Between Length and Resolution:** While the 1.57 floor is reachable at $n=1024$ (**Gens 32, 35, 37, 38**), the **Current Best Program** and **Generations 30, 34, and 36** utilize longer sequences ($n=1152$ or $n=1280$) to stabilize the result. Increasing the sequence length $n$ provides more degrees of freedom to flatten the autoconvolution peaks without significantly increasing the computational cost within the 10-second budget.
+*   **Impact of Mutation Ratios:** The successful programs maintain a specific mutation balance: high probability for peak-focused gradient steps ($\approx$ 65-70%) and low probability for random noise or structural changes ($\approx$ 5-10%). This heavy bias toward exploitation (gradient refinement) is necessary because the binomial seeds already provide a high-quality global starting point.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Progressive Resolution Upsampling:** Implement a structured strategy that begins optimization at a lower resolution (e.g., $n=512$) to rapidly settle into the correct global basin, then uses `np.interp` to upsample the sequence to $n=2048$ or higher for the final refinement stages. Higher resolution provides more degrees of freedom to "shave off" the maximum values of the autoconvolution profile, which is essential for precision as the sequence approaches the 1.57 limit.
+
+2. **Adam-style Per-Element Learning Rates:** Replace the global step size in the multiplicative update with an Adam-like mechanism that maintains running estimates of the first and second moments of the gradients (`m_t` and `v_t`). By scaling the update of each sequence element by $1 / (\sqrt{v_t} + \epsilon)$, the optimizer can make significant progress on "flat" indices while making very fine adjustments to the indices that cause the sharpest convolution peaks, preventing the "zig-zagging" behavior seen in standard momentum.
+
+3. **Dynamic Peak-Weighting Exponent:** Transition the exponential weighting constant (currently fixed at `100.0` in the current best) into a dynamic parameter that increases over the course of the run (e.g., `100.0 * (1.0 + progress_ratio)`). Increasing the exponent "sharpens" the gradient's focus onto the absolute maximum of the convolution as the profile flattens, ensuring the optimizer doesn't waste budget adjusting sub-peaks that are already safely below the current maximum.
+
+4. **Nesterov Accelerated Gradient (NAG):** Upgrade the standard momentum update to Nesterov's version by calculating the peak-targeting gradient at the "look-ahead" position (`seq - momentum * velocity`). This allows the optimizer to anticipate the curvature of the autoconvolution landscape and reduce velocity before overshooting a local minimum, which is particularly effective in the narrow, high-dimensional "valleys" characteristic of $L_\infty$ optimization problems.
+
+5. **Iterative Spectral-Spatial Projection:** Introduce a "projection" mutation that sequentially applies symmetry enforcement, a low-pass FFT filter, and then a spatial "clipping" to maintain non-negativity. Alternating between the frequency domain (to ensure global smoothness) and the spatial domain (to handle the local peaks and non-negativity) mimics the successful Gerchberg-Saxton style algorithms used in phase retrieval and can help the sequence escape the 1.57 plateau.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Exponentially Weighted Peak Gradients:** The most consistent success factor across the current best program and **Generations 44, 47, 48, and 49** is the use of exponential weighting to approximate a gradient for the non-differentiable $L_\infty$ norm of the autoconvolution. By applying weights like `np.exp(100.0 * (c[p] - m) / m)`, the optimizer focuses intensely on the highest peaks while maintaining a smooth gradient for nearby bottlenecks. This allows multiple programs to reach the **1.57 objective value** consistently.
+*   **Diverse Analytical Seeding (Binomial & U-Shape):** Starting the optimization from mathematically informed distributions remains the most critical factor for entering the correct basin of attraction. The **Current Best Program** and **Generation 44** utilize binomial seeds ($a_i \approx a_{i-1} \cdot \frac{2i-k}{2i}$) with $k \approx 1.0$, while the **Current Best** also includes U-shaped seeds (`((idx + 0.5) * (n_len - idx - 0.5))**-0.5`). These seeds provide a global structure that random or flat starts cannot easily replicate.
+*   **Multiplicative Updates and Entropic Mirror Descent:** Successful implementations (**Generations 45, 47, and the Current Best**) have transitioned to multiplicative updates (e.g., `seq * np.exp(-step * velocity)`). This technique naturally enforces the non-negativity constraint and behaves like entropic mirror descent, which is particularly effective for optimizing distributions on a simplex or scale-invariant objectives where maintaining relative ratios is more important than absolute additive changes.
+*   **Symmetry and Spectral Regularization:** Incorporating structural priors such as sequence symmetry (`(seq + seq[::-1]) / 2.0`) and low-pass FFT filtering (seen in the **Current Best** and **Generation 48**) prevents the optimization from falling into "jagged" local minima. By zeroing out high-frequency components of the sequence, the algorithm preserves the smooth global curvature necessary to minimize the autoconvolution peak.
+
+## Ineffective Approaches
+
+*   **Numerical Instability in Adam-style Optimizers:** While Adam is a standard tool, it frequently failed in this specific task (**Generations 42 and 46**). The feedback suggests that standard Adam logic, when applied to the log-gradients or multiplicative updates of convolution peaks, often led to numerical instability or failure to converge within the 10-second budget compared to simpler momentum-based gradient descent.
+*   **Library Import Failures:** Despite sophisticated algorithmic logic, **Generation 43** failed entirely (score 0.0) due to missing `numpy` and `time` imports. This mirrors failures in previous generations (e.g., Gen 33), indicating that environment setup remains a recurring point of failure for more complex multi-file or modular implementations.
+*   **Over-reliance on Complex Local Search Heuristics:** **Generation 40** utilized a "Spectral-Gradient Simulated Annealing" approach but failed to produce a valid result (score 0.0). This suggests that overly complex hybrid mutation strategies can introduce logic errors or fail to meet the specific constraints of the objective function, whereas more direct gradient-based refinement on binomial seeds (as in **Gen 44-49**) is more robust.
+
+## Implementation Insights
+
+*   **Adaptive Resolution Ladders:** The **Current Best Program** and **Generation 45** demonstrate that starting at a lower resolution ($n=1024$) and upsampling via `np.interp` to $n=1280$ is highly effective. This allows the optimizer to find a stable global minimum quickly and then refine the "peaks" at a higher resolution, providing more degrees of freedom to satisfy the AC inequality.
+*   **Scale-Invariant Normalization for Stability:** The **Current Best Program** utilizes a custom `_normalize_scale` function that forces `sum(seq) == len(seq)`. While the objective is theoretically scale-invariant, this specific normalization prevents floating-point overflow during the exponential weighting phase ($e^{100 \dots}$) and ensures the gradient magnitudes remain predictable across different sequence lengths.
+*   **Sharpened Bottleneck Targeting:** The **Current Best** uses a specific thresholding logic: `threshold = m - 0.002 * (m - np.mean(c))`. This identifies only the most significant "bottleneck" peaks in the autoconvolution, preventing the gradient from being diluted by minor fluctuations and focusing the optimization effort where it is most needed to lower the $L_\infty$ norm.
+
+## Performance Analysis
+
+*   **The 1.57 Convergence Plateau:** A clear performance ceiling has emerged at the value of **1.57** (approximating $\pi/2$). This value was achieved by **Generations 44, 45, 47, 48, and 49**, as well as the **Current Best**. Success is no longer defined by achieving a lower score, but by the reliability and speed with which an algorithm can reach this theoretical limit.
+*   **Sequence Length vs. Convergence:** While the 1.57 value is reachable at $n=1024$ (**Generations 44, 48, 49**), the programs that utilized $n=1280$ (**Generation 45, 47, and the Current Best**) tended to produce more stable results. The additional coefficients at $n=1280$ provide a smoother autoconvolution profile, making it easier for the gradient descent to "flatten" the maximum peak.
+*   **Mutation Budget Allocation:** The most successful programs (scoring 1.57) allocate approximately **65-70%** of their computational budget to gradient-based refinement and only **5-10%** to random noise or structural changes. This confirms that once a binomial seed provides a good global starting point, intensive local exploitation is the most effective path to the 1.57 limit.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Dynamic Schedule for Peak-Weighting and Thresholds:** Transition the fixed parameters in the gradient calculation—specifically the exponential weighting constant (currently `100.0`) and the bottleneck threshold (currently `0.002`)—into time-dependent schedules. Start with a lower exponent (e.g., `50.0`) and a wider threshold to capture a broad gradient, then exponentially increase the weight (up to `500.0+`) and tighten the threshold as the deadline approaches to focus all optimization pressure on the absolute $L_\infty$ maximum.
+
+2. **Projected Multiplicative Gradient Descent:** Rather than treating symmetry enforcement and FFT filtering as independent mutations, integrate them as "projections" applied after every successful multiplicative update. This ensures the sequence remains on the manifold of smooth, symmetric distributions throughout the entire optimization process, preventing the "jaggedness" that often arises from high-weight exponential gradients and allowing for more aggressive step sizes.
+
+3. **Structured Resolution Laddering (Curriculum Learning):** Implement a formal resolution curriculum that starts optimization at $n=512$ to rapidly solve the global structure, then performs a one-way upsampling to $n=1024$ and finally $n=2048$ for the last 20% of the time budget. Higher resolutions provide the necessary degrees of freedom to "shave off" the tops of the autoconvolution peaks that become immovable at lower $n$ once the 1.57 plateau is reached.
+
+4. **Second-Moment Adaptive Step Sizes (Adam-Multiplicative):** Replace the static list of `step` values with a per-element adaptive learning rate inspired by Adam, applied to the multiplicative update (`seq * np.exp(-step * velocity / (np.sqrt(v_t) + eps))`). Maintaining a running estimate of gradient variance ($v_t$) will allow the optimizer to accelerate adjustments on the "shoulders" of the sequence while maintaining precision on the critical coefficients that control the convolution maximum.
+
+5. **Binomial Parameter ($k$) Optimization Loop:** Since the binomial seed $a_i \approx a_{i-1} \cdot \frac{2i-k}{2i}$ is the most successful starting point, dedicate the first 5% of the budget to a 1D golden-section search or fine-grained sweep over the $k$ parameter (e.g., $k \in [0.8, 1.2]$). Finding the optimal $k$ for a specific target $n$ can place the initial sequence much closer to the global minimum than the current fixed-choice strategy, significantly reducing the work required by the gradient descent phase.

+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Multi-Resolution Laddering and Upsampling**: The most consistent high-performing programs (Generations 50, 51, 54, 58, 59, and the Current Best) utilize a resolution laddering strategy. They typically start optimization at $n=1024$ and progressively upsample to $n=1280$, $n=1536$, or even $n=2048$ (as seen in **Generation 50 and 51**). This allows the algorithm to find a coarse global minimum and then refine the "peaks" of the autoconvolution at higher resolutions where more degrees of freedom are available to "flatten" the maximum values.
+*   **Exponentially Weighted Max-Convolution Gradients**: To navigate the non-differentiable $L_\infty$ norm of the autoconvolution, successful programs use a sharpened softmax or exponential weighting scheme. The **Current Best Program** and **Generation 54** apply weights like `np.exp(100.0 * (c[p] - m) / m)` to the gradient. This focuses the optimization specifically on the indices contributing to the highest peaks, effectively "pushing down" the maximum value while ignoring non-critical parts of the sequence.
+*   **Physics-Inspired and Binomial Seeding**: Starting from diverse analytical distributions is more effective than random initialization. The **Current Best Program**, **Generation 50**, and **Generation 59** all utilize binomial seeds (based on the recurrence $a_i = a_{i-1} \cdot \frac{2i-k}{2i}$) and U-shaped distributions. These seeds provide a smooth, near-optimal global structure that gradient descent can quickly refine to the theoretical 1.57 plateau.
+*   **Multiplicative Mirror Descent Updates**: Successful implementations (**Current Best**, **Generation 58**, and **Generation 47**) utilize multiplicative updates (e.g., `seq * np.exp(-step * velocity)`). This approach naturally maintains the non-negativity constraint and functions as entropic mirror descent, which is more robust for scale-invariant objectives like the AC inequality than standard additive gradient descent.
+
+## Ineffective Approaches
+
+*   **Hardcoded Resolution Constraints**: **Generation 53** failed (score 0.0) despite a sophisticated gradient approach because it hardcoded a final sequence length of 1152, which did not align with the evaluator's expected dimensions. Similarly, **Generation 56** failed due to reliance on fixed-length noise (1024) that did not adapt to the required sequence constraints.
+*   **Unconstrained Exponential Scaling**: **Generation 55** implemented an exponential gradient multiplicative update but failed all validation tests. Feedback suggests that unconstrained exponential scaling leads to numerical instability or overflow, especially when the target objective is sensitive to the scale of coefficients.
+*   **Inaccurate Max-Operator Gradient Approximations**: **Generation 57** (Adam-Mirror Ladder) failed because it likely struggled with the non-smooth nature of the maximum operator. Without the specific "sharpened" weighting used in successful programs (like the `100.0` multiplier in the **Current Best**), standard momentum-based approaches often fail to effectively lower the absolute maximum peak of the autoconvolution.
+
+## Implementation Insights
+
+*   **Stable Normalization for Numerical Precision**: The **Current Best Program** utilizes a custom `_normalize_scale` function that ensures `sum(seq) == len(seq)`. While the AC objective is theoretically scale-invariant, this normalization is critical for preventing floating-point overflow during the exponential weighting phase and keeping the gradient magnitudes predictable across different sequence lengths.
+*   **Threshold-Based Bottleneck Targeting**: The **Current Best** employs a specific thresholding logic: `threshold = m - 0.002 * (m - np.mean(c))`. This isolates only the most significant "bottleneck" peaks in the autoconvolution, preventing the gradient from being diluted by minor fluctuations and focusing the optimization effort where it most impacts the objective.
+*   **Symmetry and Spectral Regularization**: Programs that achieved 1.57 (**Current Best**, **Generation 51**) often enforce symmetry via `(seq + seq[::-1]) / 2.0` and use FFT-based low-pass filtering. These operations act as structural priors that prevent the optimizer from drifting into "jagged" or asymmetric local minima that characterize sub-optimal sequences.
+*   **Adaptive Line Search in Log-Space**: The **Current Best** performs an adaptive line search across a range of step sizes `[0.001, 0.005, ..., 0.08]` using exponential updates. This ensures that every successful step monotonically decreases the objective while maintaining the relative proportions of the sequence.
+
+## Performance Analysis
+
+*   **The 1.57 Objective Plateau**: A clear performance ceiling exists at **1.57** (approximating $\pi/2$). This score has been consistently reached by **Generations 50, 51, 54, 58**, and the **Current Best**. Programs achieving this value typically utilize a combination of binomial seeds and a high-resolution final pass ($n \ge 1024$).
+*   **Effect of Sequence Length on Stability**: While 1.57 is achievable at $n=1024$ (**Generation 54, 58**), the **Current Best** and **Generation 51** demonstrate that higher resolutions ($n=1280$ to $n=2048$) provide more consistent results. The additional coefficients allow for a smoother autoconvolution profile, making it easier for the optimizer to "flatten" the max peak.
+*   **Convergence vs. Complexity**: Simpler momentum-based gradient descent on focused peaks (**Generation 59, 1.58**) performed slightly worse than those using the highly sharpened `100.0` exponent weighting (**Current Best, 1.57**). This suggests that the "sharpness" of the peak-targeting mechanism is the primary differentiator between near-optimal and optimal performance.
+*   **Computational Budget Allocation**: The most successful programs allocate the majority of their budget (approx. 70%) to gradient refinement and a significant portion to the initial multi-start seed sweep. Random mutations (swaps, jitter) are generally less effective and are only used as fallback mechanisms in the most robust programs.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+1. **Dynamic Schedule for Peak-Weighting and Thresholds**: Transition the fixed parameters in the gradient calculation—specifically the exponential weighting constant (currently `100.0`) and the bottleneck threshold (currently `0.002`)—into time-dependent schedules. Start the optimization with a lower exponent (e.g., `50.0`) and a wider threshold (e.g., `0.01`) to capture a broad gradient, then exponentially increase the weight (up to `500.0+`) and tighten the threshold as the deadline approaches to focus all optimization pressure on the absolute $L_\infty$ maximum.
+
+2. **Projected Multiplicative Gradient Descent**: Rather than treating symmetry enforcement and FFT filtering as independent rare mutations, integrate them as "projections" applied after every successful multiplicative update. This ensures the sequence remains on the manifold of smooth, symmetric distributions throughout the entire optimization process, preventing the "jaggedness" that often arises from high-weight exponential gradients and allowing for more aggressive step sizes without losing global structure.
+
+3. **Structured Resolution Laddering (Curriculum Learning)**: Implement a formal resolution curriculum that starts optimization at $n=512$ to rapidly solve the global structure, then performs a one-way upsampling to $n=1024$ and finally $n=2048$ for the last 20% of the time budget. Higher resolutions provide the necessary degrees of freedom to "shave off" the tops of the autoconvolution peaks that become immovable at lower $n$ once the 1.57 plateau is reached, followed by a final interpolation back to the target length.
+
+4. **Second-Moment Adaptive Step Sizes (Multiplicative Adam)**: Replace the current list of static `step` values with a per-element adaptive learning rate inspired by the Adam optimizer, but applied to the multiplicative update: `seq * np.exp(-step * m_t / (np.sqrt(v_t) + eps))`. Maintaining running estimates of the gradient mean ($m_t$) and variance ($v_t$) specifically for the multiplicative log-space updates will allow the optimizer to accelerate adjustments on the "shoulders" of the sequence while maintaining high precision on the critical coefficients that control the convolution maximum.
+
+5. **Binomial Parameter ($k$) Optimization Loop**: Since the binomial seed $a_i = a_{i-1} \cdot \frac{2i-k}{2i}$ is the most successful starting point, dedicate the first 5-10% of the budget to a fine-grained sweep or a golden-section search over the $k$ parameter (e.g., $k \in [0.8, 1.2]$). Finding the optimal $k$ for a specific target $n$ can place the initial sequence much closer to the theoretical 1.57 minimum than the current fixed-choice strategy, significantly reducing the iterations required by the gradient descent phase.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Binomial-Specific Seeding with Parameter Sweeping**: The most successful programs consistently initialize with analytical binomial sequences. **Generation 61, 68, and 69** all achieved the optimal **1.57** score by sweeping binomial variants (e.g., using the recurrence $a_i = a_{i-1} \cdot \frac{2i-k}{2i}$ with $k \approx 1.0$). **Generation 68** specifically identified the seed $(1-x)^{-k/2}$ as a high-quality baseline that places the optimization in a near-optimal basin from the start.
+*   **Sharpened Entropic Mirror Descent**: Transitioning from additive gradients to multiplicative updates (Entropic Mirror Descent) is crucial for maintaining non-negativity and scale invariance. The **Current Best Program** and **Generation 61** utilize a "sharpened" gradient where convolution peaks are weighted exponentially (e.g., `np.exp(100.0 * (c[p] - m) / m)`). This focuses optimization pressure exclusively on the maximum values of the autoconvolution, effectively "flattening" the objective.
+*   **Resolution Laddering (Upsampling)**: Progressing from lower to higher sequence lengths allows the algorithm to find a global structure before refining high-frequency details. **Generation 60** reached 1.58 at $n=2048$, while **Generation 66 and 69** reached **1.57** by laddering from 1024 up to 1536. This strategy prevents the optimizer from getting stuck in "jagged" local minima that occur when optimizing high-resolution sequences from scratch.
+*   **Spectral Regularization (FFT Filtering)**: To counteract the noise introduced by high-weight gradient updates, successful programs like **Generation 66** and the **Current Best** incorporate FFT-based low-pass filtering. This ensures the sequence remains smooth and symmetric, which is a structural property of optimal solutions for the AC inequality.
+
+## Ineffective Approaches
+
+*   **Missing Dependency Imports**: A cluster of programs in the Gen 60s (**Generations 62, 63, and 64**) failed with a score of **0.0** because they omitted basic `import numpy` or `import time` statements within the executable block. Even sophisticated logic like "Adam-Mirror Descent" (Gen 65) or "Resolution Laddering" (Gen 67) resulted in total failure due to these boilerplate errors.
+*   **Numerical Overflow in Peak Detection**: **Generation 63** attempted to use an extremely high exponential weight (120.0) for peak detection. Feedback indicated this caused numerical overflow during gradient descent. The **Current Best Program** balances this by using a weight of 100.0 combined with a robust normalization function to keep values within stable floating-point ranges.
+*   **Unstructured Mutations**: While the **Current Best** includes sparse noise and swaps as a fallback, programs that relied too heavily on random jitter or power transforms without targeted gradient refinement (like the failed attempts in **Generation 64**) could not reach the 1.57 plateau. Purely stochastic approaches are insufficient for the precision required to flatten convolution peaks.
+
+## Implementation Insights
+
+*   **Adaptive Log-Space Line Search**: The **Current Best Program** implements a line search that tests a range of step sizes `[0.001, 0.005, ..., 0.08]` using the multiplicative update `seq * np.exp(-step * velocity)`. This ensures that every update step is guaranteed to either improve the objective or maintain the current best, preventing "over-shooting" during the sensitive final refinement stages.
+*   **Precise Thresholding for Bottlenecks**: Rather than calculating a gradient for the entire autoconvolution, the **Current Best** uses `threshold = m - 0.002 * (m - np.mean(c))` to isolate only the most significant peaks. This targeted approach prevents "gradient dilution" where improvements to one peak inadvertently raise others.
+*   **Symmetry Enforcement**: The **Current Best** and **Generation 66** explicitly enforce symmetry via `(seq + seq[::-1]) / 2.0`. Since the autoconvolution of a sequence is related to its spectral properties, maintaining symmetry reduces the search space and stabilizes the descent toward the 1.57 limit.
+*   **Scale-Stable Normalization**: The `_normalize_scale` function in the **Current Best** (setting `sum(seq) == len(seq)`) is critical. While the AC ratio is scale-invariant, this specific normalization prevents the exponential weighting in the gradient calculation from exploding or vanishing, ensuring consistent "pressure" on the convolution peaks regardless of sequence length.
+
+## Performance Analysis
+
+*   **The 1.57 Convergence Plateau**: There is a definitive performance ceiling at **1.57** (approx. $\pi/2$). This value was reached by **Generations 61, 66, 68, 69**, and the **Current Best**. The convergence to this specific value across multiple different implementations (Entropic Mirror Descent, Binomial Sweeps, and Resolution Laddering) suggests it is the global optimum for the tested sequence lengths ($1024 \le n \le 1536$).
+*   **Resolution vs. Efficiency**: While **Generation 60** achieved 1.58 at $n=2048$, the **Current Best** and **Generation 61** achieved the superior **1.57** at a lower $n=1280$. This indicates that beyond a certain threshold (around $n=1024$), the quality of the optimization logic and the starting seed are more important for the score than increasing the sequence length.
+*   **Stability of Binomial Seeds**: Programs that started with binomial seeds (**Generation 68, 69**) consistently outperformed those using power-law or sine-based seeds. The binomial distribution provides a "smooth" convolution profile that requires significantly less refinement to reach the 1.57 target compared to noisy or flat initializations.
+*   **Impact of Momentum**: Comparing **Generation 59 (1.58)** to **Generation 60 (1.58)** and the **Current Best (1.57)** shows that momentum-augmented gradients help in navigating the complex landscape of the $L_\infty$ norm, allowing the optimizer to "push through" local plateaus where the maximum peak might shift between different indices.

+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+Based on the success of the current best program and the evolution of the 1.57 convergence plateau, here are five actionable recommendations for future program mutations:
+
+1.  **Annealed Peak Weighting and Thresholding**: The current program uses a fixed exponential weight of `100.0` and a fixed bottleneck threshold of `0.002`. Transition these into a dynamic schedule: start with a weight of `20.0` and a threshold of `0.05` to capture a broad gradient and establish global structure, then exponentially increase the weight to `250.0+` and tighten the threshold to `0.0005` in the final 20% of the time budget. This "annealing" focuses all optimization pressure on the absolute $L_\infty$ maximum as the sequence approaches the 1.57 limit.
+
+2.  **Symmetry-Preserving Multiplicative Updates**: Currently, symmetry is enforced as a stochastic mutation. Instead, integrate it directly into the gradient descent step by symmetrizing the gradient itself (`grad = (grad + grad[::-1]) / 2.0`) before applying the multiplicative update. This ensures that every step remains on the manifold of symmetric sequences, which the 1.57-scoring programs suggest is a structural requirement for the global optimum, significantly reducing the search space dimensionality.
+
+3.  **Quadratic Interpolation for Line Search**: The current program tests six discrete `step` values. Replace this with a three-point quadratic fit: evaluate the objective at steps `[0.0, 0.01, 0.04]`, fit a parabola to these points, and jump directly to the predicted minimum of that parabola. This allows for much more precise "shaving" of the autoconvolution peaks, which is critical when the improvements become marginal (e.g., moving from 1.575 to 1.571).
+
+4.  **Spectral Damping of High-Frequency "Jitter"**: While the current program uses a hard FFT cutoff, a "spectral damping" approach may be more effective. Multiply the FFT coefficients by a Gaussian window $e^{-f^2 / (2\sigma^2)}$ after each update, where $\sigma$ starts large and gradually decreases. This prevents the "jaggedness" often introduced by high-weight exponential gradients while preserving the essential mid-frequency components of the binomial-like shape.
+
+5.  **Multi-Stage Resolution Escalation**: Rather than choosing a random resolution change, implement a deterministic ladder: spend the first 2s at $n=512$ to find the optimal $k$ and general shape, then interpolate to $n=1024$ for 4s of refinement, and finally to $n=1536$ for the remaining time. Higher resolutions provide more "degrees of freedom" to flatten the convolution; starting at a lower resolution ensures the high-resolution phase begins in a near-optimal basin, avoiding local minima.

+
+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Momentum-Augmented Entropic Mirror Descent (EMD)**: The most consistent high-performing programs (**Generations 70, 77, and 79**) utilize EMD with multiplicative updates (`seq * np.exp(-step * velocity)`). This approach naturally maintains non-negativity and is better suited for simplex-like or scale-invariant constraints than standard SGD. Integrating momentum (typically 0.65) helps the optimizer navigate the non-smooth $L_\infty$ landscape of the autoconvolution peaks.
+*   **High-Resolution Binomial Sweep Initialization**: Starting from a mathematically grounded basin remains the strongest predictor of success. **Generation 79 (Current Best)** and **Generation 70** both achieved the **1.57** plateau by performing an initial grid search over binomial sequences $(1-x)^{-k/2}$ with $k$ values near 1.0 (e.g., `np.linspace(0.96, 1.04, 33)`). This places the optimization in a near-optimal region before any gradient steps are taken.
+*   **Annealed Softmax Gradient Weighting**: To optimize the non-differentiable maximum of the autoconvolution, successful programs use a softmax-weighted gradient. **Generation 79** uses an aggressive exponent schedule (`exponent = 50.0 + 750.0 * total_elapsed`) to concentrate gradient pressure on the highest peaks. **Generation 77** and **70** used similar sharpening techniques to "flatten" the convolution profile effectively.
+*   **Periodic Structural Regularization**: Maintaining the global shape of the sequence is vital to avoid local minima. The **Current Best Program (Gen 79)** and **Generation 70** periodically apply symmetrization (`(s + s[::-1]) / 2`) and smoothing kernels. This ensures the sequence remains within the structural family of optimal solutions for the AC inequality.
+
+## Ineffective Approaches
+
+*   **Incomplete Resolution Laddering**: While laddering (scaling from $n=1024$ to $2048$) was hypothesized to help, **Generations 71 and 72** only achieved a score of **2.00** despite the higher sequence length. This suggests that without the specific binomial initialization or if the refinement logic is insufficiently tuned for high dimensions ($n=2048$), the optimizer can stall at a suboptimal local minimum.
+*   **Boilerplate and Import Errors**: **Generations 76 and 78** failed completely (score **0.0**) due to validation errors or missing imports (e.g., `numpy` or `time`). This highlights that even sophisticated strategies like "Resolution-Laddering Mirror Descent" are useless if the implementation lacks basic execution robustness.
+*   **Overshooting the 1.57 Plateau**: **Generation 73** achieved a poor score of **3.46** despite using entropic mirror descent. Its failure stemmed from an ineffective combination of parameters that likely caused the sequence to deviate from the optimal binomial-like shape, proving that gradient-based refinement must be carefully constrained by line searches or small step sizes.
+
+## Implementation Insights
+
+*   **Multiplicative Line Search**: The **Current Best Program (Gen 79)** implements a "mini line search" for every update, testing step sizes `[0.001, 0.002, 0.005, 0.01, 0.02, 0.04]`. This prevents the "gradient explosion" often associated with exponential weighting and ensures that every step strictly improves the objective or maintains the best-found value.
+*   **Gradient via Correlation**: To compute the update for the autoconvolution, **Gen 79** correctly identifies that the gradient of $\max(\text{conv}(a, a))$ is proportional to $2 \cdot \text{correlate}(\text{weights}, a)$. Using `np.correlate(weights, best_seq, mode='valid')` allows for efficient computation of the sensitivity of convolution peaks to changes in the input sequence.
+*   **Time-Aware Scheduling**: The effectiveness of **Generation 79** is partly due to its use of `total_elapsed` to scale the softmax exponent. By starting with a lower exponent (50.0) and ending very high (800.0), it transitions from a broad optimization of all peaks to a laser-focused refinement of the absolute maximum.
+*   **Scale-Invariant Normalization**: **Gen 79** employs a normalization function that keeps `sum(seq) == len(seq)`. While the objective ratio is scale-invariant, keeping the sequence values in a predictable range (around 1.0) is critical for the stability of the `np.exp()` and `np.power()` operations used in the update and mutation phases.
+
+## Performance Analysis
+
+*   **The 1.57 Convergence Ceiling**: A significant number of programs (**Gens 70, 77, 79**) have converged exactly to **1.57** at a sequence length of $n=1536$. This value (approximately $\pi/2$) appears to be the practical global minimum for this range of $n$.
+*   **Sequence Length vs. Score**: There is no linear correlation between sequence length and score beyond a certain point. **Generation 71** used $n=2048$ but scored **2.00**, whereas **Generation 79** used $n=1536$ to achieve **1.57**. This indicates that the quality of the starting manifold (Binomial) and the refinement algorithm (Mirror Descent) are more important than the raw resolution of the sequence.
+*   **Efficiency of Binomial Initialization**: The sweep in **Gen 79** is highly efficient. By testing 33 variants of the binomial seed at the start, the program identifies a starting value very close to 1.57 within the first second of execution, leaving the remaining 9 seconds for high-precision local refinement.
+*   **Symmetry as a Complexity Reducer**: Programs that enforced symmetry (like the **Current Best** and **Gen 71**) tended to be more stable. Symmetrization acts as a strong prior that effectively halves the dimensionality of the search space, allowing Mirror Descent to converge faster within the 10-second budget.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+Based on the success of the current best program (Generation 79) and the analysis of the 1.57 convergence plateau, here are five actionable recommendations for future program mutations:
+
+1.  **Deterministic Symmetry Integration**: The current best program applies symmetrization stochastically (`rng.random() < 0.3`). Evidence suggests that the optimal sequence for the 1.57 plateau is strictly symmetric. Instead of stochastic application, enforce symmetry at every iteration by symmetrizing the gradient (`grad = (grad + grad[::-1]) / 2.0`) and the resulting sequence. This reduces the search space dimensionality by half, allowing the Mirror Descent algorithm to converge more quickly and accurately on the high-resolution manifold.
+
+2.  **Adaptive Quadratic Line Search**: Replace the current discrete step-size search (`[0.001, ..., 0.04]`) with a quadratic interpolation approach. Evaluate the objective at three points (e.g., step sizes 0, 0.01, and 0.02), fit a parabola to the results, and jump directly to the predicted minimum. This provides a more precise learning rate for "shaving" the autoconvolution peaks, which is essential for breaking the 1.57 plateau where improvements become extremely marginal.
+
+3.  **Dynamic Softmax "Cooling" Schedule**: Generation 79 uses a linear schedule for the softmax exponent (`50.0 + 750.0 * total_elapsed`). Refine this by using a more aggressive exponential or power-law schedule (e.g., $50 \cdot 16^t$) and introducing a "bottleneck threshold." In the final 20% of the time budget, zero out all gradient components associated with convolution values that are less than 99.9% of the current maximum. This ensures that the optimizer doesn't inadvertently raise secondary peaks while trying to lower the primary one.
+
+4.  **Spectral Gradient Smoothing**: To prevent the "jaggedness" or high-frequency noise that often arises from aggressive multiplicative updates, apply a Gaussian smoothing kernel directly to the gradient before the Mirror Descent step. This is more effective than periodic sequence smoothing (used in Gen 79) because it prevents the noise from being integrated into the sequence in the first place, maintaining the natural binomial-like curvature required for low autoconvolution.
+
+5.  **Multi-Stage Resolution Escalation**: While $n=1536$ is the current standard, implement a deterministic ladder: spend 2s at $n=512$ to find the optimal binomial $k$ and establish the global profile, interpolate to $n=1024$ for 4s of refinement, and finish at $n=2048$ for the final 4s. Higher resolutions provide more degrees of freedom to "flatten" the convolution peaks; starting at a lower resolution ensures the high-resolution phase begins in a near-optimal basin, avoiding the local minima that hindered previous high-res attempts (like Gen 71).

+# GLOBAL INSIGHTS SCRATCHPAD
+
+The following are global insights about optimization approaches and their effectiveness:
+
+## Successful Algorithmic Patterns
+
+*   **Systematic Binomial Sweep Initialization**: Starting with a sequence family based on $(1-x)^{-k/2}$ is the single most effective strategy for reaching the theoretical lower bound. The **Current Best Program (Gen 79/83)** and **Generation 81** utilize a grid search over $k$ (e.g., `np.linspace(0.94, 1.06, 41)`) to find a global starting point near the 1.57 objective value. This avoids the local minima that trap purely stochastic or uniform initializations.
+*   **Momentum-Augmented Entropic Mirror Descent (EMD)**: Utilizing multiplicative updates (`seq * np.exp(-step * velocity)`) preserves the non-negativity constraint while naturally handling the scale-invariant nature of the objective. High-performing programs like **Generations 81, 83, and 89** use this approach with a momentum factor (typically 0.75) to navigate the non-smooth autoconvolution landscape.
+*   **Annealed Softmax Peak Weighting**: To optimize the $L_\infty$ norm (maximum peak) of the autoconvolution, successful programs use a softmax-weighted gradient. The **Current Best Program** uses an aggressive exponent schedule (`50.0 + 950.0 * total_elapsed`) to focus the gradient on the highest convolution peaks as the search progresses.
+*   **Resolution Laddering (Intermediate Success)**: Scaling the sequence resolution (e.g., from $n=1024$ to $n=1536$ or $2048$) allows the optimizer to refine high-frequency details. **Generation 89** achieved a valid (though slightly worse) objective of 2.00 at $n=2048$ by laddering up from 1536, suggesting this is a viable path for high-precision refinement if properly constrained.
+
+## Ineffective Approaches
+
+*   **High-Resolution Dimensionality Trap**: While laddering to $n=2048$ was intended to improve precision, **Generations 82, 85, and 89** only reached an objective of **2.00**, whereas **Generations 81, 83, and 84** reached **1.57** at $n=1536$. This indicates that increasing $n$ without significantly more iterations or a better-tuned gradient can lead to worse relative performance due to the $2n$ term in the objective function.
+*   **Continuous Optimization Oversimplification**: **Generations 80 and 87** failed (score **0.0**) because they treated the problem as a purely continuous optimization task, failing to account for the discrete boundaries or specific format requirements of the target problem. 
+*   **Numerical Instability in Complex Transitions**: Programs like **Generation 86** and **88** failed validation despite using sophisticated mirror descent and laddering. The feedback for **Gen 86** specifically points to the complexity of resolution transitions and strict symmetry enforcement introducing numerical errors that prevented convergence within the 10-second budget.
+
+## Implementation Insights
+
+*   **Gradient Calculation via Cross-Correlation**: The most effective way to calculate the gradient for the autoconvolution is identifying that the sensitivity of $\max(\text{conv}(a, a))$ is proportional to the cross-correlation of the peak weights and the sequence itself. The **Current Best Program** implements this using `np.correlate(weights, best_seq, mode='valid')`.
+*   **Spectral Gradient Smoothing**: To maintain the structural integrity of the binomial-like profile, the **Current Best Program** and **Generation 83** apply a Gaussian-like smoothing kernel to the gradient (`[s_width, 1.0 - 2*s_width, s_width]`). This prevents the multiplicative updates from creating "spiky" sequences that would increase the maximum convolution peak.
+*   **Granular Multiplicative Line Search**: To ensure monotonic improvement, the **Current Best Program** tests multiple small step sizes (`[0.0002, 0.0005, 0.001, 0.002, 0.005, 0.01, 0.02]`) for every update. This prevents the "gradient explosion" risk inherent in exponential updates.
+*   **Time-Aware Exponent Scaling**: The **Current Best Program** uses `total_elapsed` to scale the softmax exponent from 50.0 to 1000.0. This allows the optimizer to initially smooth several high peaks before focusing intensely on the absolute maximum in the final seconds of execution.
+
+## Performance Analysis
+
+*   **The 1.57 Plateau vs. n=2048**: There is a clear performance divide based on sequence length. Programs targeting $n=1536$ (**Gen 81, 83, 84, 79**) consistently achieved the superior score of **1.57**. Programs targeting $n=2048$ (**Gen 82, 85, 89**) converged to **2.00**. This suggests that $n=1536$ is the current "sweet spot" for balancing resolution and optimization complexity within the time limit.
+*   **Symmetry as a Stabilizer**: Programs that achieved 2.00 or 1.57 often enforced sequence symmetry (**Gen 82, 85, 89**). Symmetry acts as a dimensionality reduction technique, effectively halving the number of parameters the Mirror Descent algorithm must optimize, which leads to faster convergence.
+*   **Initialization Efficiency**: The 33-41 point binomial sweep used in the **Current Best Program** and **Gen 81** is highly efficient. It typically finds a near-optimal sequence within the first 10-15% of the time budget, allowing the remainder of the time to be used for high-precision local gradient refinement.
+*   **Robustness Failures**: A high percentage of the "Resolution Laddering" programs (**Gens 80, 86, 87, 88**) failed entirely. This suggests that while laddering and sophisticated gradients are powerful, they are highly sensitive to implementation errors, numerical overflow in `np.exp`, or failure to normalize sequences correctly after interpolation.
+
+# META RECOMMENDATIONS
+
+The following are actionable recommendations for the next program generations:
+
+Based on the success of the current best program and the analysis of the 1.57 convergence plateau, here are five actionable recommendations for future program mutations:
+
+1.  **Deterministic Symmetry Enforcement**: The current best program applies symmetrization stochastically. Evidence suggests the optimal sequence for this inequality is strictly symmetric. Enforce symmetry at every iteration by symmetrizing both the gradient (`grad = (grad + grad[::-1]) / 2`) and the sequence itself; this effectively halves the dimensionality of the search space, allowing Mirror Descent to converge much faster on high-resolution manifolds.
+
+2.  **Parabolic Step-Size Optimization**: Replace the discrete step-size search with a local quadratic fit to find the optimal learning rate. By evaluating the objective at three small step sizes (e.g., $0, \epsilon$, and $2\epsilon$), you can fit a parabola and jump directly to the predicted minimum. This precision is vital for "shaving" the final decimal points of the autoconvolution peaks when progress becomes extremely marginal.
+
+3.  **Resolution Laddering with Interpolation**: To break the 1.57 plateau, use a multi-stage approach: spend the first 30% of the budget at $n=768$ to rapidly find the global basin using the binomial sweep, then interpolate the sequence to $n=1536$ or $n=2048$ for high-precision refinement. This "warm start" prevents the optimizer from getting trapped in the local minima that frequently plague high-resolution starts while providing the degrees of freedom needed for a lower objective.
+
+4.  **Exponential Softmax Cooling and Hard Thresholding**: Transition from a linear to an exponential schedule for the softmax exponent (e.g., $50 \cdot (1000/50)^t$) to focus the gradient more aggressively as time expires. In the final 15% of the time budget, introduce a "hard-threshold" where weights for all convolution indices below 99.9% of the current maximum are set to zero, forcing the gradient to exclusively target the absolute peaks.
+
+5.  **Momentum-Refined Gradient Smoothing**: Instead of periodic sequence smoothing, apply a constant Gaussian smoothing kernel directly to the momentum-augmented gradient. This prevents the "jaggedness" or high-frequency oscillations introduced by aggressive multiplicative updates from ever being integrated into the sequence, maintaining the smooth, binomial-like curvature required for minimizing the $L_\infty$ norm of the autoconvolution.

+  "meta_scratch_pad": "## Successful Algorithmic Patterns\n\n*   **Symmetrized Resolution Laddering with FFT Interpolation:** The most effective programs (**Current Best**, **Generations 192, 196**) utilize a multi-stage approach, optimizing first at lower resolutions (e.g., 1024 or 1536) before upsampling to $n=2048$. Using `np.interp` combined with spectral smoothing (like the `[0.05, 0.9, 0.05]` kernel in the **Current Best**) allows the optimizer to establish a smooth global \"U-shape\" before refining high-frequency convolution peaks.\n*   **Binomial-Seed Parameter Sweeps:** Rather than random initialization, the top-performing programs (**Current Best**, **Generation 199**) perform a targeted sweep of binomial sequences $(1-x)^{-k/2}$ with $k$ values near 1.0 (specifically $0.98$ to $1.02$). This provides a mathematically robust starting point that is already close to the structural optimum for the autoconvolution objective, which is then refined via gradient descent.\n*   **Multiplicative Mirror Descent with Nesterov Momentum:** Incorporating multiplicative updates (`seq * exp(-lr * grad)`) instead of additive ones has proven critical for maintaining non-negativity and handling the wide dynamic range of coefficients. When paired with Nesterov-style predictive look-ahead (**Current Best**, **Generation 193**), this approach efficiently navigates the complex, non-convex landscape of the autoconvolution maximum.\n*   **Softmax-Weighted Gradient Targeting:** Replacing the non-differentiable `max()` with a softmax-weighted sum of the convolution peaks allows for precise gradient-based refinement. The **Current Best** program employs a \"cooling\" or \"sharpening\" schedule, increasing the softmax exponent from 100 to 900 over the run duration to focus the optimization on the most problematic peaks.\n\n## Ineffective Approaches\n\n*   **Execution Runtime Failures (Missing Imports):** A significant number of sophisticated programs (**Generations 191, 195, 198**) failed entirely (score 0.0) because they omitted basic `import numpy` or `import time` statements within the execution block. This highlights that even the most advanced mathematical logic is useless without fundamental coding hygiene in the standalone environment.\n*   **Aggressive Resolution Jumps Without Smoothing:** While laddering is effective, jumps that are too large or lack subsequent smoothing can introduce high-frequency artifacts. **Generation 197** attempted a ladder from 512 to 2048 but only achieved a score of **2.07**, significantly worse than the **1.57** achieved by programs using more gradual or smoothed transitions (like **Gen 192** and **196**).\n*   **Static Step Sizes in Mirror Descent:** Programs that do not implement adaptive step-size mechanisms (like the micro-line search in the **Current Best**) often suffer from \"catastrophic divergence\" where the sequence values explode or collapse to zero when the gradient becomes steep, resulting in poorer evaluation values (e.g., **Generation 194**'s score of **3.53**).\n\n## Implementation Insights\n\n*   **Efficiency via Correlation Gradients:** The **Current Best** and **Generation 193** optimize gradient calculation by using `np.correlate(weights, sequence, mode='valid')`. This identifies the contribution of each coefficient to the weighted convolution peaks without requiring the computation of the full Jacobian, significantly increasing the number of iterations possible within the 10-second budget.\n*   **Micro-Line Search for Stability:** The **Current Best** program implements a micro-line search at each step, evaluating `alpha * 0.5`, `alpha`, and `alpha * 2.0`. This ensures that the Mirror Descent step is always taking the most productive path, contributing to the **0.00 standard deviation** and high reliability seen in its performance metrics.\n*   **Symmetry Projection:** Explicitly enforcing sequence symmetry (`(seq + seq[::-1]) / 2`) at each iteration or during the look-ahead step (**Current Best**, **Generation 192**) effectively halves the search space and stabilizes the autoconvolution profile, as the optimal non-negative sequences for this problem are known to be largely symmetric.\n*   **PAPR-Driven Dynamic Sharpening:** **Generation 196** and **197** experimented with \"PAPR-driven\" (Peak-to-Average Power Ratio) adjustments to the gradient, attempting to use the sequence's own distribution to scale updates. While complex, the most successful version of this remains the softmax-weighted peak optimization used in the **Current Best**.\n\n## Performance Analysis\n\n*   **The 1.57 Convergence Floor:** There is a clear performance plateau at **1.57** (at $n=2048$). Multiple programs (**Generations 192, 196,** and the **Current Best**) hit this exact value. This suggests that the combination of binomial seeding and Nesterov Mirror Descent has effectively solved the structural requirements of the $n=2048$ sequence.\n*   **Sequence Length Impact:** There is a direct correlation between sequence length and the objective value $2n \\cdot \\text{max}(B) / (\\text{sum } A)^2$. **Generation 190** achieved 1.57 at $n=1536$, but the majority of top scores are achieved at $n=2048$. The extra resolution allows for more gradual \"tapering\" of the sequence ends, which minimizes the autoconvolution peaks relative to the total sum.\n*   **Reliability vs. Complexity:** The **Current Best Program** demonstrates that reliability (zero variance) is achieved by replacing stochastic elements with a comprehensive initial sweep (the 9-point binomial sweep) followed by deterministic gradient refinement. Programs that relied too heavily on random mutations or simulated annealing alone (e.g., **Generation 197**) showed significantly higher (worse) evaluation values.\n*   **Optimization Efficiency:** Comparison between **Generation 194 (3.53)** and **Generation 192 (1.57)** shows that high-resolution optimization ($n=2048$) is only effective if the gradient correctly targets the convolution peaks. Simply using a high-resolution sequence without the focused softmax-weighted gradient results in much higher objective values.",
+  "meta_recommendations": "Based on the successful patterns identified in the 1.57 plateau and the logic of the current best program, here are five actionable recommendations for future program mutations:\n\n1.  **Replace Linear Interpolation with FFT-based Upsampling**: Instead of using `np.interp` for resolution laddering, implement spectral zero-padding by transforming the sequence to the frequency domain with `np.fft.rfft`, padding the high-frequency components with zeros, and transforming back. This prevents the high-frequency \"kinks\" introduced by linear interpolation, ensuring that the smooth, band-limited \"U-shape\" remains intact when transitioning to the final $n=2048$ resolution.\n\n2.  **Implement PAPR-Driven Dynamic Softmax Focusing**: Shift from a time-based linear ramp for the softmax exponent ($100 \\to 900$) to an adaptive mechanism driven by the Peak-to-Average Power Ratio (PAPR) of the convolution profile. By scaling the exponent based on the ratio of `max(conv) / mean(conv)`, the optimizer can automatically sharpen its focus when a single dominant peak emerges and broaden its focus when multiple peaks compete, preventing premature convergence to local sub-optima.\n\n3.  **Integrate Multiplicative Adam/RMSProp Scaling**: Enhance the Nesterov Mirror Descent by adding a second-moment tracker (like RMSProp) to the multiplicative update: `cache = decay * cache + (1 - decay) * grad**2`. Normalizing the update by `step * grad / (np.sqrt(cache) + eps)` prevents the large gradients at the sequence boundaries from dominating the update, allowing for more precise, high-resolution adjustments in the sequence center where the autoconvolution is most sensitive.\n\n4.  **Apply Spectral Gradient Filtering**: Instead of the current 3-point spatial smoothing kernel, apply a low-pass Gaussian filter to the gradient in the frequency domain before the Mirror Descent update. This ensures that the updates primarily reinforce the low-frequency global structure that drives the 1.57 score, effectively \"filtering out\" high-frequency noise that could lead to the formation of new, unwanted autoconvolution spikes.\n\n5.  **Introduce Late-Stage Symmetry Relaxation**: While symmetry is a powerful constraint, the 1.57 plateau may represent a local minimum for perfectly symmetric sequences. In the final 10% of the execution budget, replace the strict `(seq + seq[::-1]) / 2` projection with a relaxed version, `(1-eta)*seq + eta*seq[::-1]` where `eta` decays from 0.5 to 0.48, allowing the optimizer to \"shave\" persistent peaks that cannot be suppressed under perfect symmetry.",
+  "meta_recommendations_history": [
+    "1. **Implement Adaptive Gradient-Step Scaling:** Instead of a fixed 0.04 alpha in the \"Multi-peak gradient reduction\" mutation, implement an adaptive step size or a line-search approach. Since the objective is scale-invariant, the sequence should be re-normalized after every gradient step, and the step size could be halved if a mutation fails to improve the score, allowing for finer convergence around the 1.57 optima.\n\n2. **Integrate \"Generalized Binomial\" and Windowed Seeds:** The binomial sequence $a_i = a_{i-1} \\cdot \\frac{2i-1}{2i}$ is a powerful seed, but its performance might be improved by parameterizing it as $a_i = a_{i-1} \\cdot \\frac{2i-k}{2i}$ for $k \\in [0.5, 1.5]$. Additionally, applying windowing functions (like Tukey or Hann windows) to initial seeds can help suppress edge effects in the convolution that contribute to central peaks.\n\n3. **Incorporate Success-Based Adaptive Mutation Probabilities:** Replace the fixed mutation thresholds (0.30, 0.65, etc.) with a dynamic system that tracks which mutation type has yielded the most \"best_val\" improvements during the run. By increasing the probability of successful mutations (likely the gradient reduction and upsampling) and decreasing failing ones (like random swaps if they prove too destructive at high lengths), the search becomes more efficient as the deadline approaches.\n\n4. **Enforce Sequence Symmetry via Mirroring Mutations:** The convolution of a symmetric sequence often exhibits more predictable peak behavior. Add a mutation that replaces the sequence with its average mirror image `(seq + seq[::-1]) / 2.0` or simply mirrors one half to the other; this reduces the search space dimensionality and may help stabilize the gradient-informed peak reduction.\n\n5. **Transition to a Simulated Annealing Acceptance Criterion:** The current \"greedy\" local search (`val < best_val`) is prone to getting trapped in local minima, as seen in the plateauing scores around 1.6-1.7. Implementing a simple Metropolis-Hastings acceptance criterion\u2014where slightly worse sequences are accepted with a probability $P = \\exp(-\\Delta V / T)$ and a cooling temperature $T$\u2014could allow the algorithm to escape suboptimal \"peak configurations\" and find more global optima.",
+    "1. **Implement Adaptive Learning Rate for Gradient Mutations:** The current multi-peak gradient reduction uses a fixed step size of 0.04. Replace this with a \"line search\" or \"decaying learning rate\" approach where the mutation is only accepted if it improves the objective, or the step size (alpha) is reduced by half whenever a move fails to produce an improvement, allowing the sequence to converge more precisely at the 1.57 plateau.\n\n2. **Parameterize the Binomial Seed Distribution:** The standard binomial sequence ($a_i = a_{i-1} \\cdot \\frac{2i-1}{2i}$) has been the most successful starting point. Extend this by parameterizing the seed as $a_i = a_{i-1} \\cdot \\frac{2i-k}{2i}$ where $k$ is sampled between 0.5 and 1.5, allowing the algorithm to explore a wider family of power-law decays that may yield better initial basins than the fixed mathematical identity.\n\n3. **Enforce Sequence Symmetry via Mirroring Mutations:** Since many optimal autocorrelation sequences are symmetric, introduce a mutation that enforces symmetry by replacing the sequence with its mirrored average: `(seq + seq[::-1]) / 2.0`. This reduces the search dimensionality and forces the gradient reduction to treat the \"left\" and \"right\" sides of the convolution peaks identically, which can stabilize the optimization.\n\n4. **Transition to a Simulated Annealing Acceptance Criterion:** The current \"greedy\" search logic only accepts improvements, which often leads to local optima at high sequence lengths. Implement a Metropolis-Hastings acceptance rule where a worse sequence is accepted with probability $P = \\exp(-\\Delta V / T)$, using a temperature $T$ that cools over the duration of the budget; this allows the sequence to \"reorganize\" its peak structure.\n\n5. **Incorporate Windowing Functions to Suppress Edge Artifacts:** Convolution results are highly sensitive to the values at the beginning and end of the sequence. Add a mutation that applies a Tukey or Hann window to the sequence, or specifically smooths the boundary elements ($a_0$ to $a_{n/10}$ and $a_{9n/10}$ to $a_{n-1}$), to prevent sharp edges from creating unnecessary secondary peaks in the autocorrelation function.",
+    "1. **Dynamic Peak Targeting Threshold:** Instead of a static 99% threshold for identifying convolution peaks in the gradient descent step, use a dynamic threshold that scales with the search progress (e.g., `max_c - (max_c - mean_c) * 0.01`). This ensures that as the convolution profile flattens, the optimizer continues to focus only on the most significant bottlenecks rather than being diluted by an increasing number of sub-peaks that have already been sufficiently suppressed.\n\n2. **Symmetry-Enforcement Mutations:** Introduce a mutation that periodically forces the sequence to be perfectly symmetric using `seq = (seq + seq[::-1]) / 2.0`. Mathematical theory for optimal autoconvolution sequences often points toward symmetric or near-symmetric distributions; enforcing this reduces the search space dimensionality and prevents the gradient reduction from creating asymmetric oscillations that lead to higher peak values.\n\n3. **Adaptive Step-Size Line Search:** Replace the fixed 0.04 multiplier in the gradient mutation with a mini-line search. For each gradient update, evaluate the objective at three step sizes (e.g., 0.01, 0.04, 0.1) and select the best one, or implement a decay where the step size is halved whenever 50 iterations pass without an improvement. This is crucial for breaking the 1.57 plateau, where very fine adjustments are required to navigate the high-dimensional landscape.\n\n4. **Momentum-Augmented Gradients:** Incorporate a \"momentum\" term into the multi-peak gradient logic by storing the previous gradient direction: `velocity = 0.9 * velocity + 0.1 * current_grad`. Applying updates based on this velocity helps the optimizer \"carry through\" consistent descent directions and avoids the \"zig-zagging\" behavior that occurs when the optimizer oscillates between targeting different sets of peaks in successive iterations.\n\n5. **Spectral Smoothing via FFT:** Implement a mutation that applies a low-pass filter in the frequency domain (FFT -> zero out/attenuate high frequencies -> Inverse FFT). While the current program uses a 1-2-1 spatial smoother, spectral smoothing can more effectively eliminate high-frequency \"jitter\" across the entire sequence length simultaneously, which often causes the sharp, localized peaks in the convolution that limit the current best score.",
+    "1. **Progressive Resolution Upsampling:** Implement a structured strategy that begins optimization at a lower resolution (e.g., $n=512$) to rapidly settle into the correct global basin, then uses `np.interp` to upsample the sequence to $n=2048$ or higher for the final refinement stages. Higher resolution provides more degrees of freedom to \"shave off\" the maximum values of the autoconvolution profile, which is essential for precision as the sequence approaches the 1.57 limit.\n\n2. **Adam-style Per-Element Learning Rates:** Replace the global step size in the multiplicative update with an Adam-like mechanism that maintains running estimates of the first and second moments of the gradients (`m_t` and `v_t`). By scaling the update of each sequence element by $1 / (\\sqrt{v_t} + \\epsilon)$, the optimizer can make significant progress on \"flat\" indices while making very fine adjustments to the indices that cause the sharpest convolution peaks, preventing the \"zig-zagging\" behavior seen in standard momentum.\n\n3. **Dynamic Peak-Weighting Exponent:** Transition the exponential weighting constant (currently fixed at `100.0` in the current best) into a dynamic parameter that increases over the course of the run (e.g., `100.0 * (1.0 + progress_ratio)`). Increasing the exponent \"sharpens\" the gradient's focus onto the absolute maximum of the convolution as the profile flattens, ensuring the optimizer doesn't waste budget adjusting sub-peaks that are already safely below the current maximum.\n\n4. **Nesterov Accelerated Gradient (NAG):** Upgrade the standard momentum update to Nesterov's version by calculating the peak-targeting gradient at the \"look-ahead\" position (`seq - momentum * velocity`). This allows the optimizer to anticipate the curvature of the autoconvolution landscape and reduce velocity before overshooting a local minimum, which is particularly effective in the narrow, high-dimensional \"valleys\" characteristic of $L_\\infty$ optimization problems.\n\n5. **Iterative Spectral-Spatial Projection:** Introduce a \"projection\" mutation that sequentially applies symmetry enforcement, a low-pass FFT filter, and then a spatial \"clipping\" to maintain non-negativity. Alternating between the frequency domain (to ensure global smoothness) and the spatial domain (to handle the local peaks and non-negativity) mimics the successful Gerchberg-Saxton style algorithms used in phase retrieval and can help the sequence escape the 1.57 plateau.",
+    "1. **Dynamic Schedule for Peak-Weighting and Thresholds:** Transition the fixed parameters in the gradient calculation\u2014specifically the exponential weighting constant (currently `100.0`) and the bottleneck threshold (currently `0.002`)\u2014into time-dependent schedules. Start with a lower exponent (e.g., `50.0`) and a wider threshold to capture a broad gradient, then exponentially increase the weight (up to `500.0+`) and tighten the threshold as the deadline approaches to focus all optimization pressure on the absolute $L_\\infty$ maximum.\n\n2. **Projected Multiplicative Gradient Descent:** Rather than treating symmetry enforcement and FFT filtering as independent mutations, integrate them as \"projections\" applied after every successful multiplicative update. This ensures the sequence remains on the manifold of smooth, symmetric distributions throughout the entire optimization process, preventing the \"jaggedness\" that often arises from high-weight exponential gradients and allowing for more aggressive step sizes.\n\n3. **Structured Resolution Laddering (Curriculum Learning):** Implement a formal resolution curriculum that starts optimization at $n=512$ to rapidly solve the global structure, then performs a one-way upsampling to $n=1024$ and finally $n=2048$ for the last 20% of the time budget. Higher resolutions provide the necessary degrees of freedom to \"shave off\" the tops of the autoconvolution peaks that become immovable at lower $n$ once the 1.57 plateau is reached.\n\n4. **Second-Moment Adaptive Step Sizes (Adam-Multiplicative):** Replace the static list of `step` values with a per-element adaptive learning rate inspired by Adam, applied to the multiplicative update (`seq * np.exp(-step * velocity / (np.sqrt(v_t) + eps))`). Maintaining a running estimate of gradient variance ($v_t$) will allow the optimizer to accelerate adjustments on the \"shoulders\" of the sequence while maintaining precision on the critical coefficients that control the convolution maximum.\n\n5. **Binomial Parameter ($k$) Optimization Loop:** Since the binomial seed $a_i \\approx a_{i-1} \\cdot \\frac{2i-k}{2i}$ is the most successful starting point, dedicate the first 5% of the budget to a 1D golden-section search or fine-grained sweep over the $k$ parameter (e.g., $k \\in [0.8, 1.2]$). Finding the optimal $k$ for a specific target $n$ can place the initial sequence much closer to the global minimum than the current fixed-choice strategy, significantly reducing the work required by the gradient descent phase.",

Start the optimization with a lower exponent (e.g., `50.0`) and a wider threshold (e.g., `0.01`) to capture a broad gradient, then exponentially increase the weight (up to `500.0+`) and tighten the threshold as the deadline approaches to focus all optimization pressure on the absolute $L_\\infty$ maximum.\n\n2. **Projected Multiplicative Gradient Descent**: Rather than treating symmetry enforcement and FFT filtering as independent rare mutations, integrate them as \"projections\" applied after every successful multiplicative update. This ensures the sequence remains on the manifold of smooth, symmetric distributions throughout the entire optimization process, preventing the \"jaggedness\" that often arises from high-weight exponential gradients and allowing for more aggressive step sizes without losing global structure.\n\n3. **Structured Resolution Laddering (Curriculum Learning)**: Implement a formal resolution curriculum that starts optimization at $n=512$ to rapidly solve the global structure, then performs a one-way upsampling to $n=1024$ and finally $n=2048$ for the last 20% of the time budget. Higher resolutions provide the necessary degrees of freedom to \"shave off\" the tops of the autoconvolution peaks that become immovable at lower $n$ once the 1.57 plateau is reached, followed by a final interpolation back to the target length.\n\n4. **Second-Moment Adaptive Step Sizes (Multiplicative Adam)**: Replace the current list of static `step` values with a per-element adaptive learning rate inspired by the Adam optimizer, but applied to the multiplicative update: `seq * np.exp(-step * m_t / (np.sqrt(v_t) + eps))`. Maintaining running estimates of the gradient mean ($m_t$) and variance ($v_t$) specifically for the multiplicative log-space updates will allow the optimizer to accelerate adjustments on the \"shoulders\" of the sequence while maintaining high precision on the critical coefficients that control the convolution maximum.\n\n5. **Binomial Parameter ($k$) Optimization Loop**: Since the binomial seed $a_i = a_{i-1} \\cdot \\frac{2i-k}{2i}$ is the most successful starting point, dedicate the first 5-10% of the budget to a fine-grained sweep or a golden-section search over the $k$ parameter (e.g., $k \\in [0.8, 1.2]$). Finding the optimal $k$ for a specific target $n$ can place the initial sequence much closer to the theoretical 1.57 minimum than the current fixed-choice strategy, significantly reducing the iterations required by the gradient descent phase.",
+    "Based on the success of the current best program and the evolution of the 1.57 convergence plateau, here are five actionable recommendations for future program mutations:\n\n1.  **Annealed Peak Weighting and Thresholding**: The current program uses a fixed exponential weight of `100.0` and a fixed bottleneck threshold of `0.002`. Transition these into a dynamic schedule: start with a weight of `20.0` and a threshold of `0.05` to capture a broad gradient and establish global structure, then exponentially increase the weight to `250.0+` and tighten the threshold to `0.0005` in the final 20% of the time budget. This \"annealing\" focuses all optimization pressure on the absolute $L_\\infty$ maximum as the sequence approaches the 1.57 limit.\n\n2.  **Symmetry-Preserving Multiplicative Updates**: Currently, symmetry is enforced as a stochastic mutation. Instead, integrate it directly into the gradient descent step by symmetrizing the gradient itself (`grad = (grad + grad[::-1]) / 2.0`) before applying the multiplicative update. This ensures that every step remains on the manifold of symmetric sequences, which the 1.57-scoring programs suggest is a structural requirement for the global optimum, significantly reducing the search space dimensionality.\n\n3.  **Quadratic Interpolation for Line Search**: The current program tests six discrete `step` values. Replace this with a three-point quadratic fit: evaluate the objective at steps `[0.0, 0.01, 0.04]`, fit a parabola to these points, and jump directly to the predicted minimum of that parabola. This allows for much more precise \"shaving\" of the autoconvolution peaks, which is critical when the improvements become marginal (e.g., moving from 1.575 to 1.571).\n\n4.  **Spectral Damping of High-Frequency \"Jitter\"**: While the current program uses a hard FFT cutoff, a \"spectral damping\" approach may be more effective. Multiply the FFT coefficients by a Gaussian window $e^{-f^2 / (2\\sigma^2)}$ after each update, where $\\sigma$ starts large and gradually decreases. This prevents the \"jaggedness\" often introduced by high-weight exponential gradients while preserving the essential mid-frequency components of the binomial-like shape.\n\n5.  **Multi-Stage Resolution Escalation**: Rather than choosing a random resolution change, implement a deterministic ladder: spend the first 2s at $n=512$ to find the optimal $k$ and general shape, then interpolate to $n=1024$ for 4s of refinement, and finally to $n=1536$ for the remaining time. Higher resolutions provide more \"degrees of freedom\" to flatten the convolution; starting at a lower resolution ensures the high-resolution phase begins in a near-optimal basin, avoiding local minima.",
+    "Based on the success of the current best program (Generation 79) and the analysis of the 1.57 convergence plateau, here are five actionable recommendations for future program mutations:\n\n1.  **Deterministic Symmetry Integration**: The current best program applies symmetrization stochastically (`rng.random() < 0.3`). Evidence suggests that the optimal sequence for the 1.57 plateau is strictly symmetric. Instead of stochastic application, enforce symmetry at every iteration by symmetrizing the gradient (`grad = (grad + grad[::-1]) / 2.0`) and the resulting sequence. This reduces the search space dimensionality by half, allowing the Mirror Descent algorithm to converge more quickly and accurately on the high-resolution manifold.\n\n2.  **Adaptive Quadratic Line Search**: Replace the current discrete step-size search (`[0.001, ..., 0.04]`) with a quadratic interpolation approach. Evaluate the objective at three points (e.g., step sizes 0, 0.01, and 0.02), fit a parabola to the results, and jump directly to the predicted minimum. This provides a more precise learning rate for \"shaving\" the autoconvolution peaks, which is essential for breaking the 1.57 plateau where improvements become extremely marginal.\n\n3.  **Dynamic Softmax \"Cooling\" Schedule**: Generation 79 uses a linear schedule for the softmax exponent (`50.0 + 750.0 * total_elapsed`). Refine this by using a more aggressive exponential or power-law schedule (e.g., $50 \\cdot 16^t$) and introducing a \"bottleneck threshold.\" In the final 20% of the time budget, zero out all gradient components associated with convolution values that are less than 99.9% of the current maximum. This ensures that the optimizer doesn't inadvertently raise secondary peaks while trying to lower the primary one.\n\n4.  **Spectral Gradient Smoothing**: To prevent the \"jaggedness\" or high-frequency noise that often arises from aggressive multiplicative updates, apply a Gaussian smoothing kernel directly to the gradient before the Mirror Descent step. This is more effective than periodic sequence smoothing (used in Gen 79) because it prevents the noise from being integrated into the sequence in the first place, maintaining the natural binomial-like curvature required for low autoconvolution.\n\n5.  **Multi-Stage Resolution Escalation**: While $n=1536$ is the current standard, implement a deterministic ladder: spend 2s at $n=512$ to find the optimal binomial $k$ and establish the global profile, interpolate to $n=1024$ for 4s of refinement, and finish at $n=2048$ for the final 4s. Higher resolutions provide more degrees of freedom to \"flatten\" the convolution peaks; starting at a lower resolution ensures the high-resolution phase begins in a near-optimal basin, avoiding the local minima that hindered previous high-res attempts (like Gen 71).",
+    "Based on the success of the current best program and the analysis of the 1.57 convergence plateau, here are five actionable recommendations for future program mutations:\n\n1.  **Deterministic Symmetry Enforcement**: The current best program applies symmetrization stochastically. Evidence suggests the optimal sequence for this inequality is strictly symmetric. Enforce symmetry at every iteration by symmetrizing both the gradient (`grad = (grad + grad[::-1]) / 2`) and the sequence itself; this effectively halves the dimensionality of the search space, allowing Mirror Descent to converge much faster on high-resolution manifolds.\n\n2.  **Parabolic Step-Size Optimization**: Replace the discrete step-size search with a local quadratic fit to find the optimal learning rate. By evaluating the objective at three small step sizes (e.g., $0, \\epsilon$, and $2\\epsilon$), you can fit a parabola and jump directly to the predicted minimum. This precision is vital for \"shaving\" the final decimal points of the autoconvolution peaks when progress becomes extremely marginal.\n\n3.  **Resolution Laddering with Interpolation**: To break the 1.57 plateau, use a multi-stage approach: spend the first 30% of the budget at $n=768$ to rapidly find the global basin using the binomial sweep, then interpolate the sequence to $n=1536$ or $n=2048$ for high-precision refinement. This \"warm start\" prevents the optimizer from getting trapped in the local minima that frequently plague high-resolution starts while providing the degrees of freedom needed for a lower objective.\n\n4.  **Exponential Softmax Cooling and Hard Thresholding**: Transition from a linear to an exponential schedule for the softmax exponent (e.g., $50 \\cdot (1000/50)^t$) to focus the gradient more aggressively as time expires. In the final 15% of the time budget, introduce a \"hard-threshold\" where weights for all convolution indices below 99.9% of the current maximum are set to zero, forcing the gradient to exclusively target the absolute peaks.\n\n5.  **Momentum-Refined Gradient Smoothing**: Instead of periodic sequence smoothing, apply a constant Gaussian smoothing kernel directly to the momentum-augmented gradient. This prevents the \"jaggedness\" or high-frequency oscillations introduced by aggressive multiplicative updates from ever being integrated into the sequence, maintaining the smooth, binomial-like curvature required for minimizing the $L_\\infty$ norm of the autoconvolution.",

+    "1. **Strict Symmetry Enforcement at High Resolution**: While the current best program initializes with symmetric sequences and occasionally symmetrizes, evidence suggests the optimal solution is perfectly symmetric. Forcing symmetry at every iteration\u2014by averaging the gradient with its reverse (`grad = (grad + grad[::-1]) / 2`) and the sequence itself\u2014effectively halves the search space dimensionality. This reduction is critical for achieving faster convergence on the $n=1536$ or $n=2048$ manifolds within the tight 10-second budget.\n\n2. **Parabolic Step-Size Optimization**: Replace the current discrete \"Granular Multiplicative Line Search\" (testing 7 fixed steps) with a local quadratic fit. By evaluating the objective at three small relative step sizes (e.g., $0, \\eta$, and $2\\eta$), you can fit a parabola to the results and jump directly to the predicted minimum. This precision is vital for \"shaving\" the final decimal points of the autoconvolution peaks when progress using discrete steps plateaus.\n\n3. **Resolution Laddering with Cubic Interpolation**: To improve the 1.57 benchmark, implement a two-stage \"warm start\" strategy. Spend the first 25% of the time budget at $n=768$ to rapidly find the global basin using the binomial sweep and high-speed Mirror Descent, then use cubic interpolation (`scipy.interpolate.interp1d`) to upsample the sequence to $n=1536$ or $2048$ for high-resolution refinement. This avoids the high-frequency local minima that often trap high-resolution starts while providing the degrees of freedom needed for a lower objective value.\n\n4. **Exponential Softmax Cooling and Hard Peak-Targeting**: Transition from a linear to an exponential schedule for the softmax exponent (e.g., scaling from 50 to 2000) to focus the gradient more aggressively on the absolute maximum of the convolution. In the final 10% of the time budget, introduce a \"hard-threshold\" where weights for all convolution indices below 99.5% of the current maximum are set to zero, forcing the optimizer to exclusively minimize the dominant peaks that define the $L_\\infty$ norm.\n\n5. **Curvature-Aware Gradient Smoothing**: Synchronize the spectral smoothing kernel width with the softmax exponent schedule. As the exponent increases to target sharp peaks, the Gaussian smoothing kernel width should decrease (e.g., from 0.20 down to 0.01) to allow the sequence to develop the high-frequency features necessary to \"fill\" the gaps between peaks. This prevents the smoothing from fighting the optimization in the final exploitation phase while maintaining stability during the initial exploration.",
+    "1. **Mandatory Symmetry Constraint at High Resolution**: The current best program only symmetrizes 5% of the time, yet the most successful high-resolution runs (Gens 113, 121) enforced symmetry throughout. Modify the Mirror Descent loop to explicitly average the gradient with its reverse (`grad = (grad + grad[::-1]) / 2`) and the sequence with its reverse at every iteration. This reduces the search space dimensionality from $n$ to $n/2$, which is critical for achieving a score below 1.57 within the 10-second budget at $n=1536$ or $n=2048$.\n\n2. **Two-Stage Multi-Resolution Laddering**: Implement a \"warm-start\" by spending the first 20% of the time budget optimizing at $n=512$ or $n=768$. Once the coarse global basin is found, upsample the sequence to $n=2048$ using `np.interp`. This allows the optimizer to rapidly establish the underlying binomial-like structure at low cost before using the remaining budget to fine-tune the high-frequency peaks that only emerge at higher resolutions.\n\n3. **Parabolic Line Search for Step-Size Optimization**: Replace the discrete 7-step \"Granular Multiplicative Line Search\" with a local quadratic fit. Evaluate the objective at three small relative step sizes (e.g., $0, \\eta, 2\\eta$), fit a parabola to the results, and jump directly to the predicted minimum. This precision is vital for \"shaving\" the final decimal points of the autoconvolution peaks when progress using discrete steps plateaus near the end of the budget.\n\n4. **Exponential Softmax Cooling with Hard-Peak Masking**: Transition from a linear to an exponential schedule for the softmax exponent (e.g., scaling from 50 to 2000) to more aggressively target the absolute maximum of the convolution. In the final 15% of the time budget, introduce a \"hard-threshold\" mask where weights for all convolution indices below 99.8% of the current maximum are set to zero, forcing the Mirror Descent to exclusively minimize the specific peaks that define the $L_\\infty$ norm.\n\n5. **Curvature-Aware Smoothing Decay**: Synchronize the spectral smoothing kernel width with the softmax exponent schedule. Start with a broader Gaussian-like kernel (side weights of 0.20) to maintain sequence stability during early exploration, but decay these weights to zero (or a very small value like 0.01) as the softmax focus narrows. This prevents the smoothing operation from \"fighting\" the optimization during the final exploitation phase where high-frequency adjustments are needed to fill the gaps between peaks.",
+    "1. **Implement Three-Stage Resolution Laddering to $n=2048$**: While the current best program achieved 1.57 at $n=1536$, the global insights show that $n=2048$ is the target for the most robust results. Implement a laddering schedule that spends 15% of the budget at $n=512$, 25% at $n=1024$, and the remainder at $n=2048$, using `np.interp` for upsampling. This allows the optimizer to solve the \"coarse\" binomial structure quickly before spending the majority of the time budget on the high-dimensional $n=2048$ landscape.\n\n2. **Mandatory Symmetry Constraint for High-Resolution Convergence**: The current best program only symmetrizes 5% of the time, but successful $n=2048$ runs (Gens 123, 125) suggest that reducing the search space is critical at high resolution. Modify the Mirror Descent loop to explicitly enforce symmetry at every iteration by averaging the sequence and its reverse (`seq = (seq + seq[::-1]) / 2.0`) and doing the same for the gradient. This halves the number of free variables, effectively doubling the optimization speed within the fixed 10-second budget.\n\n3. **Parabolic Line Search for Precise Peak Shaving**: Replace the discrete 7-step \"Granular Multiplicative Line Search\" with a local quadratic fit to more accurately find the optimal step size. Evaluate the objective at three small relative step sizes (e.g., $0, \\eta, 2\\eta$), fit a parabola to the objective values, and jump to the vertex. This precision is vital for minimizing the $L_\\infty$ norm of the convolution when progress typically plateaus using fixed or discrete step sizes.\n\n4. **Hard-Peak Masking in the Final Optimization Phase**: In the final 20% of the time budget, transition from the annealed softmax gradient to a \"hard-threshold\" mask. Instead of weighting all convolution indices, set the weights to zero for all indices whose values are less than 99.8% of the current maximum. This forces the Mirror Descent to exclusively focus its updates on the specific peaks that define the objective value, preventing \"drift\" in the rest of the sequence profile.\n\n5. **Nesterov-style Acceleration for Mirror Descent**: Upgrade the simple momentum ($0.75$) to a Nesterov-style accelerated gradient update. Calculate the gradient at the \"looked-ahead\" sequence position (`best_seq + momentum * velocity`) rather than the current position. This improvement helps the optimizer navigate the narrow, sharp ridges of the autoconvolution landscape more efficiently, which is essential as the softmax exponent increases and the gradient becomes more volatile.",
+    "1. **Implement Multi-Stage Resolution Laddering to $n=2048$**: The current best program reaches the 1.57 threshold at $n=1536$, but theory suggests $n=2048$ is the ceiling for the most competitive results. Implement a three-stage schedule (e.g., $n=512$ for 1.5s, $n=1024$ for 2.5s, $n=2048$ for 6s) using `np.interp` for upsampling to allow the Mirror Descent to converge on the coarse binomial structure quickly before performing high-resolution peak shaving.\n\n2. **Transition to Nesterov-Accelerated Mirror Descent**: Upgrade the simple 0.75 momentum to a Nesterov-style update by calculating the softmax gradient at a \"look-ahead\" sequence position (`best_seq + momentum * velocity`). This is particularly effective for navigating the narrow, sharp ridges of the convolution landscape that appear as the softmax exponent increases, preventing the oscillations that occur with standard momentum in the final optimization phase.\n\n3. **Enforce Structural Symmetry in Early Iterations**: Reduce the initial search space complexity by enforcing strict sequence symmetry ($a_i = a_{n-i-1}$) during the first 50% of the time budget. By averaging the sequence and its gradient with their mirrored versions, you effectively halve the number of free variables, which accelerates the discovery of the optimal binomial-like profile before allowing for asymmetric fine-tuning in the final stages.\n\n4. **Hard-Peak Gradient Masking in the Final Phase**: In the last 15% of the optimization budget, switch from the annealed softmax gradient to a \"hard-mask\" approach where gradient weights are set to zero for all convolution indices below 99.9% of the current maximum. This forces the Mirror Descent to focus its updates exclusively on the specific indices causing the $L_\\infty$ bottleneck, preventing \"profile drift\" in non-peak areas from accidentally increasing the objective value.\n\n5. **Quadratic Approximation for Step-Size Selection**: Replace the discrete 7-step multiplicative line search with a local quadratic fit to determine the optimal step size. By evaluating the objective at three small relative steps (e.g., $\\eta = 0, 0.001, 0.002$), the program can analytically find the vertex of the local parabolic approximation, leading to significantly more precise \"peak shaving\" than the current granular search.",
+    "1. **Implement Three-Stage Resolution Laddering to $n=2048$**: While the current best uses $n=1536$, theory suggests $n=2048$ is superior if managed efficiently. Start at $n=768$ for the first 2 seconds to rapidly converge the global binomial structure, then upsample using `np.interp` to $n=1536$ for 4 seconds, and finally to $n=2048$ for high-resolution \"peak shaving.\" This captures the computational speed of low-res and the theoretical floor of high-res.\n\n2. **Transition to Nesterov-Accelerated Multiplicative Updates**: Upgrade the 0.75 momentum to a Nesterov-style update by calculating the softmax gradient at a \"look-ahead\" sequence position (`best_seq * exp(-momentum * velocity)`). This is particularly effective for navigating the extremely narrow ridges of the convolution landscape that appear as the softmax exponent reaches 1000, preventing the oscillations seen in standard momentum.\n\n3. **Replace Discrete Line Search with Local Parabolic Approximation**: Instead of testing a fixed list of 7 step sizes, evaluate the objective at three small relative steps (e.g., $\\eta = 0.0, 0.001, 0.002$). Use these three points to fit a local quadratic and analytically find the vertex; this provides a much more precise step size for the Mirror Descent, which is critical when trying to break the 1.57 convergence floor.\n\n4. **Dynamic Softmax Exponent linked to Convolution Sparsity**: Rather than a linear time-based ramp, calculate the \"sharpness\" of the convolution peaks (e.g., the ratio of the maximum to the mean) and use it to scale the softmax exponent. This ensures that the optimization pressure remains broad while the convolution is \"lumpy\" and only focuses on the extreme $L_\\infty$ bottlenecks once the overall profile has been smoothed by the spectral gradient kernel.\n\n5. **Asymmetric Weighting for Tail-End Gradient Pressure**: Evidence suggests that the $L_\\infty$ objective is highly sensitive to the decay rates at the sequence boundaries. Apply a \"spatial\" weight to the gradient that slightly amplifies updates at the indices $i \\in [0, 0.05n]$ and $i \\in [0.95n, n]$. This forces the Mirror Descent to more aggressively optimize the \"tails\" of the binomial distribution, which are often the primary drivers of autoconvolution peaks in the final stages.",
+    "1. **Replace Linear Interpolation with FFT-based Upsampling for Laddering**: The \"1.58 plateau\" observed in laddering programs likely stems from piecewise-linear artifacts introduced by `np.interp`, which create high-frequency noise in the autoconvolution. Implement resolution transitions (e.g., $1024 \\to 1536 \\to 2048$) using FFT-based resampling (zero-padding in the frequency domain) to preserve the spectral smoothness of the binomial base and allow the $n=2048$ resolution to finally surpass the $n=1536$ fixed-resolution results.\n\n2. **Transition to Nesterov-Accelerated Mirror Descent**: Upgrade the current momentum implementation to a Nesterov-style update by calculating the softmax gradient at a \"look-ahead\" sequence position (e.g., `best_seq * np.exp(-momentum * velocity)`). This is specifically designed to handle the extremely narrow, high-curvature ridges that appear in the $L_\\infty$ landscape as the softmax exponent approaches 1000, preventing the oscillations that limit the current 1.57 best.\n\n3. **Implement Local Parabolic Line Search for Peak Shaving**: Instead of the current fixed-list multiplicative line search (7 discrete steps), evaluate the objective at three small relative step sizes (e.g., $0, \\eta, 2\\eta$). Use these points to fit a local quadratic and analytically solve for the vertex to find the optimal $\\eta$; this provides the surgical precision required to \"shave\" the final $0.01$ off the score during the last 2 seconds of the budget.\n\n4. **Apply Spatial Gradient Weighting to Sequence Boundaries**: Evidence suggests the $L_\\infty$ objective is highly sensitive to the decay rate at the sequence edges. Implement a \"spatial mask\" that amplifies the gradient updates at the first and last 5% of the sequence indices by a factor of 1.2\u20131.5; this forces the Mirror Descent to more aggressively optimize the \"tails\" of the distribution, which are often the hidden drivers of autoconvolution bottlenecks.\n\n5. **Dynamic Softmax Scaling based on Peak Ratio**: Rather than a linear time-based ramp for the softmax exponent (50 to 1000), scale the exponent based on the \"sharpness\" of the convolution peaks (e.g., $\\max(c) / \\text{mean}(c)$). This ensures the optimizer maintains a broad structural focus while the convolution is \"lumpy\" and only shifts to a \"hard\" max-proxy once the global profile is sufficiently flat, preventing premature convergence to local minima.",
+    "1. **Implement Nesterov-Accelerated Mirror Descent**: Upgrade the standard momentum implementation to a Nesterov-style \"look-ahead\" update by calculating the softmax gradient at a predicted position (e.g., `best_seq * np.exp(-momentum * velocity)`). This approach is better suited for navigating the narrow, high-curvature ridges that emerge in the autoconvolution landscape as the softmax exponent increases, preventing the oscillations that currently stall refinement at the 1.57 mark.\n\n2. **Replace Discrete Line Search with Golden Section Search**: Instead of the fixed 7-step multiplicative list, implement a Golden Section Search to find the optimal step size $\\eta$ within the range $[0.0001, 0.05]$. This provides the surgical precision required to find the exact minimum along the descent direction, which is critical for \"peak shaving\" during the final seconds of the optimization budget when discrete steps are too coarse.\n\n3. **Incorporate Late-Stage FFT-based Resolution Escalation**: Transition from $n=1536$ to $n=2048$ during the final 15% of the time budget using FFT-based upsampling (zero-padding in the frequency domain). FFT upsampling preserves the spectral integrity and smoothness of the binomial-derived profile better than linear interpolation, potentially allowing the optimizer to bypass the 1.57 plateau by refining the sequence at a higher resolution without introducing noise.\n\n4. **Dual-Track Symmetry Optimization**: Maintain two parallel sequences\u2014one strictly symmetric and one allowed to be asymmetric\u2014and optimize them simultaneously or via alternating iterations. Since the $(1-z)^{-k/2}$ anchor is symmetric, enforcing symmetry provides stability, while allowing controlled asymmetry in the \"asymmetric track\" can help the optimizer shave off persistent local peaks that a purely symmetric profile might be unable to resolve.\n\n5. **Adaptive Softmax Scaling Based on Peak Statistics**: Replace the linear time-based ramp for the softmax exponent ($50 \\to 1000$) with a dynamic scaling factor based on the ratio of the maximum convolution peak to the mean ($m / \\text{avg}(c)$). This ensures the gradient focus only sharpens once the global autoconvolution profile is sufficiently flat, preventing the optimizer from \"locking in\" on specific peaks prematurely before the broader structural U-shape is fully optimized.",
+    "Based on the successful optimization patterns and the current best program's performance at the 1.57 plateau, here are five actionable recommendations for future program mutations:\n\n1.  **Implement Closed-Loop Softmax Annealing**: Instead of the current time-based linear ramp ($100 \\to 900$), adapt the softmax exponent based on the \"flatness\" of the autoconvolution profile. Calculate the ratio between the maximum peak and the 90th percentile of the convolution; increase the exponent sharply only when this ratio drops below a certain threshold (e.g., 1.05), ensuring the gradient focuses on fine-tuning only after the global U-shape is stable.\n\n2.  **Integrate Preconditioned Mirror Descent**: Use a diagonal approximation of the Hessian to scale the learning rate for each coefficient, similar to RMSProp or Adam but adapted for the multiplicative update. By tracking a moving average of the squared gradients (`cache = decay * cache + (1 - decay) * grad**2`), you can normalize the updates across the sequence, preventing the \"edges\" of the U-shape (which often have larger gradients) from dominating the refinement of the \"center.\"\n\n3.  **Implement Fractional \"Phase-Shift\" Micro-Rolls**: Replace the discrete `np.roll` with a sub-pixel shift implemented via the Fourier Shift Theorem (multiplying the FFT of the sequence by $e^{-i 2\\pi \\delta f}$). Shifting the sequence by fractional amounts (e.g., 0.1 to 0.5 indices) can help align the autoconvolution peaks more precisely between discrete grid points, potentially lowering the maximum peak value that integer shifts cannot resolve.\n\n4.  **Multi-Stage Resolution Cascading with FFT Upsampling**: Transition through a formal resolution ladder ($n=512 \\to 1024 \\to 2048$) using spectral zero-padding (FFT upsampling) rather than linear interpolation. Spend 20% of the budget at each lower resolution to establish the macro-scale U-shape rapidly, and reserve the final 60% of the budget at $n=2048$ for high-precision Mirror Descent, as lower resolutions converge much faster to the 1.6-1.7 range.\n\n5.  **Controlled Late-Stage Symmetry Breaking**: After the optimizer reaches the 1.57 plateau using strict symmetry, introduce a \"relaxation\" phase in the final 10% of the time budget. Allow the sequence to become slightly asymmetric by reducing the weight of the symmetrization step (`seq = (1-eps)*seq + eps*seq[::-1]`, where `eps` decays from 1.0 to 0.95), which can allow the optimizer to \"shave\" specific persistent peaks that are structurally unavoidable in a perfectly symmetric profile.",
+    "Based on the success of the current best program and the evolution of the 1.57 plateau, here are five actionable recommendations for future program mutations:\n\n1.  **Replace Linear Interpolation with FFT-based Upsampling**: Instead of using `np.interp` during resolution laddering, utilize spectral zero-padding (transforming the sequence to the frequency domain with `np.fft.rfft`, padding the high frequencies with zeros, and transforming back). Linear interpolation introduces high-frequency \"kinks\" that create artificial peaks in the autoconvolution; FFT upsampling preserves the smooth, band-limited nature of the optimal U-shape, providing a superior starting point for the final $n=2048$ refinement.\n\n2.  **Implement PAPR-Driven Dynamic Softmax**: Shift from a time-based linear ramp for the softmax exponent ($100 \\to 900$) to one driven by the Peak-to-Average Power Ratio (PAPR) of the convolution. Calculate `exponent = base_exp * (max(conv) / mean(conv))`; this automatically sharpens the gradient focus only when the convolution profile is \"flat\" and contains multiple competing peaks, preventing the optimizer from over-correcting when a single dominant peak is already being addressed.\n\n3.  **Apply Spectral Gradient Filtering**: Apply a low-pass Gaussian filter to the computed gradient in the frequency domain before performing the multiplicative update. By dampening the high-frequency components of the gradient, you ensure that the Mirror Descent step prioritizes the low-frequency \"U-shape\" structure, which is the primary driver of the 1.57 score, and avoids introducing \"jitter\" that creates localized spikes in the autoconvolution.\n\n4.  **Integrate Multiplicative RMSProp/Adam Scaling**: Adapt the Mirror Descent update to include a second-moment tracker (like RMSProp) for each coefficient: `cache = decay * cache + (1 - decay) * grad**2`. Normalize the update by `step * grad / (np.sqrt(cache) + eps)`. This per-coefficient scaling prevents the large gradients at the sequence boundaries from drowning out the subtle adjustments needed in the sequence center, where the autoconvolution is most sensitive to small changes.\n\n5.  **Implement Late-Stage Stochastic Symmetry Relaxation**: After reaching a stable plateau with strict symmetry (e.g., at 90% of the budget), introduce a \"symmetry relaxation\" factor. Instead of forcing `seq = (seq + seq[::-1]) / 2`, use a weighted average `seq = (1-eta)*seq + eta*seq[::-1]` where `eta` slowly decays from 0.5 to 0.45. This allows the optimizer to \"shave\" specific, persistent peaks that may be structurally trapped by perfect symmetry, potentially breaking the 1.57 limit.",
+    "Based on the successful patterns identified in the 1.57 plateau and the logic of the current best program, here are five actionable recommendations for future program mutations:\n\n1.  **Replace Linear Interpolation with FFT-based Upsampling**: Instead of using `np.interp` for resolution laddering, implement spectral zero-padding by transforming the sequence to the frequency domain with `np.fft.rfft`, padding the high-frequency components with zeros, and transforming back. This prevents the high-frequency \"kinks\" introduced by linear interpolation, ensuring that the smooth, band-limited \"U-shape\" remains intact when transitioning to the final $n=2048$ resolution.\n\n2.  **Implement PAPR-Driven Dynamic Softmax Focusing**: Shift from a time-based linear ramp for the softmax exponent ($100 \\to 900$) to an adaptive mechanism driven by the Peak-to-Average Power Ratio (PAPR) of the convolution profile. By scaling the exponent based on the ratio of `max(conv) / mean(conv)`, the optimizer can automatically sharpen its focus when a single dominant peak emerges and broaden its focus when multiple peaks compete, preventing premature convergence to local sub-optima.\n\n3.  **Integrate Multiplicative Adam/RMSProp Scaling**: Enhance the Nesterov Mirror Descent by adding a second-moment tracker (like RMSProp) to the multiplicative update: `cache = decay * cache + (1 - decay) * grad**2`. Normalizing the update by `step * grad / (np.sqrt(cache) + eps)` prevents the large gradients at the sequence boundaries from dominating the update, allowing for more precise, high-resolution adjustments in the sequence center where the autoconvolution is most sensitive.\n\n4.  **Apply Spectral Gradient Filtering**: Instead of the current 3-point spatial smoothing kernel, apply a low-pass Gaussian filter to the gradient in the frequency domain before the Mirror Descent update. This ensures that the updates primarily reinforce the low-frequency global structure that drives the 1.57 score, effectively \"filtering out\" high-frequency noise that could lead to the formation of new, unwanted autoconvolution spikes.\n\n5.  **Introduce Late-Stage Symmetry Relaxation**: While symmetry is a powerful constraint, the 1.57 plateau may represent a local minimum for perfectly symmetric sequences. In the final 10% of the execution budget, replace the strict `(seq + seq[::-1]) / 2` projection with a relaxed version, `(1-eta)*seq + eta*seq[::-1]` where `eta` decays from 0.5 to 0.48, allowing the optimizer to \"shave\" persistent peaks that cannot be suppressed under perfect symmetry."

+Hard constraints:
+- All circles must be disjoint.
+- All circles must lie fully inside the unit square.

+# Erdos Minimum Overlap Task
+
+This task optimizes a step function `h:[0,2]->[0,1]` under:
+
+- `sum(h) == n_points / 2` (discrete integral equals 1)
+- objective: minimize
+  `C5 = max(correlate(h, 1-h) * dx)`
+
+ShinkaEvolve maximizes scores, so evaluator reports:
+
+- `combined_score = -mean_c5`
+
+Lower `C5` means better solution and therefore higher `combined_score`.
