中文说明：针对带时间窗的车辆配送问题，用遗传算法，有很多程序，这些程序都是对遗传算法中需要的函数注释以及函数用途说明。并且画图来看遗传算法的优化过程和迭代次数及最优解
English Description：
In view of the vehicle distribution problem with time window, there are many programs using genetic algorithm. These programs are the function annotation and function usage description needed in genetic algorithm. And draw a picture to see the optimization process of genetic algorithm and the number of iterations and the optimal solution
