中文说明：
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。
English Description：
I downloaded a GA-PSO algorithm from the Internet and tried to optimize it by using the combination strategy of GA and PSO. The result is that the algorithm is very problematic, efficient and good. I downloaded the original algorithm. One problem is that the upper and lower limits of all design variables are the same, so I modified and improved the program. Now I can deal with the inconsistency between the upper and lower limits, and fix some bugs
