GAPSO-share
在做优化的时候,起初选择了GA算法,但是GA的不稳定性(或者陷入局部最优)实在让人抓狂,前后两次的结果相差竟然有时候能达到30 以上,当时由于时间的原因,我只好选择了优化1000次,然后以其中的最小值最为最佳方案。虽然问题也算解决了,但是从学术上将,这种奔方法是让人很尴尬的。所以,我从网上下载了一个GA-PSO算法,试着利用GA和PSO组合的策略进行优化,结果算法很问题,效率和不错。我下载原始算法,有一个问题就是它是针对所有的设计变量上下限都是一样的,所以我对程序进行了修改与改进,现在可以处理上下限不一致的问题,同时fix了一些bug。现在把修改后的程序和大家分享一下,希望能对您有用.注意myfit需要用自己的函数,否则出错,因为我的myfit程序在调用过程中,需要使用matlab的Kriging工具箱
