说明：  pso 程序，一共三个，DeJong.m，get_psoOptions.m，pso.m结合起来就可以了，直接拷到work目录下就可以运行，其中get_psooptions中可以改设置，变成自己的； DeJong是适应函数，也可以改。
(PSO procedures, a total of three, DeJong.m, get_psoOptions.m, pso.m combine, and they can work directly Manchester directory on the run, which get_psooptions can change settings, into its own; DeJong is the fitness function, but also to change.)
