代码说明:

  一、用GA直接训练BP网络的权重算法 主程序:gafault.m 它包括以下子程序: 1. BP网络初始化:nninit.m――给出P,T,R,S1,S2; 2. 适应值计算函数:gabpEval.m; 3.将遗传算法的编码解码为BP网络所对应的权值、阈值函数:gadecod.m; 二、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 主程序:gabpfault.m 它包括以下子程序: 1. 网络初始化:nninit.m――给出P,T,R,S1,S2; 2. 适应值计算函数:gabpEval.m; 3.将遗传算法的编码解码为BP网络所对应的权值、阈值函数:gadecod.m; 三、纯BP   主程序:(1)bpfault.m 在MATLAB5.2上       (2)bpfault.m 在MATLAB6.5上 为后来所加 (First, the direct training of BP network with GA the weight algorithm Main program: gafault.m It includes the following routines: 1. BP network initialization: nninit.m-- given P, T, R, S1, S2 2. Fitness calculation functions: gabpEval.m 3. Of genetic algorithms for the BP network codec corresponding weights, the threshold function: gadecod.m Second, with the GA first aim at the weight of BP network, and then direct the training of pure BP mixture of BP algorithm GA-BP Main program: gabpfault.m It includes the following routines: 1. Network initialization: nninit.m-- given P, T, R, S1, S2 2. Fitness calculation functions: gabpEval.m 3. Of genetic algorithms for the BP network codec corresponding weights, the threshold function: gadecod.m 3, pure BP Main program: (1) bpfault.m on the MATLAB5.2 (2) bpfault.m the MATLAB6.5 for the subsequently added )
