PSO工具，用户只需要定义好自己需要优化的函数(计算最小值或者最大值)，并设置好函数自变量的取值范围、每步迭代允许的最大变化量(称为最大速度，Max_V)等，即可自行优化。(PSO tool, users only need to define their own needs optimization function (calculation of minimum or maximum), and set the good function from the range of variables, each iteration the maximum allowable variation (known as maximum speed, Max_V), etc. , can self-optimize.)
