这是计算机算法基础中的动态规划的方法的一个例子，多段图是一个很经典的问题！这里的程序用于求解最小成本路径，用类似的思想可以解决最优分配方案的问题！-This is a computer algorithm based on the dynamic programming methods of an example, many of the map is a classic question! Here the procedures for calculating the minimum cost path, with similar ideas can solve the optimal distribution program!
