greedyOptim/base_new.py

"""
Refactored base.py - now uses modular structure for better maintainability.

This module has been restructured into separate files:
- models.py: Data classes and configurations
- evaluator.py: Constraint checking and objective evaluation  
- genetic_algorithm.py: Genetic Algorithm implementation
- advanced_optimizers.py: CMA-ES, PSO, and Simulated Annealing
- scheduler.py: Main interface and comparison tools

For backward compatibility, the main functions are still available here.
