| # beam_cvar | |
| ## Summary | |
| - **Best FA**: +0.330 | |
| - **Oracle calls**: 4,358 | |
| - **Wall time**: 4 hours | |
| - **Epochs**: 191 | |
| ## Algorithm: Beam Search Active Loop | |
| 1. Beam search of width=8, guided by ensemble mean μ (deterministic scoring) | |
| 2. Beam produces K=25 candidates per epoch directly (no separate Thompson selection) | |
| 3. Evaluate K with FA oracle, CVaR fine-tune DDPP, retrain ensemble | |
| Key difference from thompson_cvar: search is directed by μ deterministically. | |
| No per-candidate exploration — always prunes toward ensemble mean. | |
| ## Config | |

| - tau_mode=cvar, tau_quantile=0.80, ddpp_steps_per_epoch=50 | |
