30个例程，非常好用，带有bp，GA，PSO等多种常见算法和模型，别看小，保证是全的-30 routines, very easy to use, with bp, GA, PSO and other common algorithms and models, do not look small, guaranteed to be full of

分别使用PSO和GA优化BP神经网络的参数，用于非线性函数拟合(PSO and GA are used to optimize the parameters of the BP neural network for nonlinear function fitting)

主要是通过GA和PSO的全局搜索能力，用于改进BP网络的权值阈值(It is mainly used to improve the weight threshold of BP network)
