说明：  粒子群优化算法 相信有不少人知道粒子群优化吧。算法简单而且寻优的速度快。我用matlab写了PSO的实现程序，相信对对这方面感兴趣的兄弟有用。为了比较直观的演示PSO的算法，用了2维的。
(PSO algorithm believe a lot of people know it PSO. A simple algorithm optimization and faster. I used Matlab was the PSO procedures, I believe this area of interest to the brothers useful. In order to compare the visual presentation of the PSO algorithm, with a two-dimensional.)
