中文说明：用遗传算法求解函数最优值，收敛速度快且不易陷入局部最优值。遗传算法是经典算法，此程序适合初学者。
English Description：
Using genetic algorithm to solve the function optimal value, the convergence speed is fast and it is not easy to fall into the local optimal value. Genetic algorithm is a classic algorithm, this program is suitable for beginners.
