算法设计于分析中的多段图问题，用VC编写应用动态规划的算法设计方法，利用最优性原理以及所获得的递推关系式求取最优决策序列，通过多段图的定义，找到由源点s到汇点t的最小成本路径，进而可以灵活解决可以用多段图描述的许多实际问题.-algorithm design in the analysis of many of the map, prepared with VC dynamic programming algorithm design, the optimum principle as well as the recursive relation to strike the optimal sequence of decision-making through more of the map defined by the source to find s t point to the Department of the minimum cost paths and further a flexible solution could spend more of the map describes the many practical problems.
