中文说明：遗传算法程序包，包括用GA直接训练BP网络的权重算法，用GA先求BP网络的权重，再用纯BP直接训练BP的混合GA－BP算法，以及纯BP算法
English Description：
The program package of genetic algorithm includes the hybrid GA-BP algorithm that uses GA to train the weight of BP network directly, the hybrid GA-BP algorithm that uses GA to calculate the weight of BP network first, and then uses pure BP to train BP directly, and the pure BP algorithm
