中文说明：基于遗传算法下对函数最大值求解。算法终止时迭代次数比较大，多数在1500-8000次，少数情况下终止的或早或晚；
English Description：
Based on genetic algorithm, the function maximum is solved. When the algorithm is terminated, the number of iterations is relatively large, most of them are 1500-8000, and in a few cases, the termination is sooner or later;
