中文说明：本程序是利用遗传算法优化BP神经网络，在算法精确度上要比单纯运用BP神经网高，程序分为三个文件，ga_bp是主文件，其他两个是相关函数文件，只需要放到一个文件夹中即可运行。
English Description：
This procedure is the use of genetic algorithm optimized BP neural network algorithm for higher accuracy than simply using BP neural network, the program is divided into three files, ga_bp is the primary file, function is related to the other two files only need to be placed in a single folder to run.
