禁用并启用本地连接.bat
有多个内网,局域网复杂时候,有时候开机会获取别的ip导致上不了网,需要禁用再启用本地连接才行。本批处理运行时候会最小化。另外网卡名字不是默认本地连接的话,需要修改批处理内 本地连接 为再用网卡名。譬如本地连接2

遗传算法优化神经网络的拓扑结构与权值
【实例简介】遗传算法(GA)和人工神经网络(ANN)的相互结合有辅助式和合作式两种方式.本文在此基础上提出了融合、BP_GA和GA_BP三种算法,并采用GA_BP算法同时优化BP神经网络的结构、权值和阈值,研究和实现了一套先进的编码技术和进化策略,克服了传统BP神经网络经验尝试方法的盲目性.实例优化与检验结果表明:遗传算法优化获得的神经网络比由经验尝试法得到的BP网络性能更优异,方法更合理.
