中文说明：
用遗传算法为 BP 神经网络优化权值，使网络具有快速学习网络权重的能力，并且能够摆脱局部极小点的困扰。遗传算法的全局搜索能力来弥补BP算法全局搜索能力不足，实例证明，这种预测模型比BP网络预测模型具有更高的精度。
English Description：
Genetic algorithm is used to optimize the weights of BP neural network, so that the network has the ability to learn the weights of the network quickly and get rid of the trouble of local minima. The global search ability of genetic algorithm can make up for the lack of global search ability of BP algorithm. The example shows that this prediction model has higher accuracy than BP network prediction model.
