Trainset Scheduling Optimization Package

This package provides multi-objective optimization algorithms for metro trainset scheduling.
It includes various optimization methods like Genetic Algorithm, CMA-ES, PSO, and Simulated Annealing.

Main classes:
- TrainsetSchedulingOptimizer: Main interface for optimization
- OptimizationConfig: Configuration parameters
- OptimizationResult: Result container

Usage:
    from greedyOptim import optimize_trainset_schedule, OptimizationConfig
    
    config = OptimizationConfig(required_service_trains=20, min_standby=3)
    result = optimize_trainset_schedule(data, method='ga', config=config)
