利用遗传算法，对一个函数求取极值的一种方法，考虑到普通遗传算法中初始种群，对极值影响较大，程序的采用了多个初试种群同时学习，相互比较以求取极大值。-Using genetic algorithm, a function of a strike extreme approach, taking into account the general genetic algorithm initial population, a greater impact on the extreme, the program uses multiple populations while learning the first test, compared with each other in order to strike a great value.
