动态规划(Dynamic Programming)是求解决策过程(decision process)最优化的数学方法.它的名字和动态没有关系,是Richard Bellman为了唬人而取的. 动态规划主要用于解决包含重叠子问题的最优化问题,其基本策略是将原问题分解为相似的子问题,通过求解并保存重复子问题的解,然后逐步合并成为原问题的解.动态规划的关键是用记忆法储存重复问题的答案,避免重复求解,以空间换取时间. 用动态规划解决的经典问题有:最短路径(shortest path),0-1背包问题(K…

*本文主要记录和分享学习到的知识,算不上原创. *参考文献见链接. 旅行商问题.背包问题都是0-1规划问题中最为经典的问题. 通常来说,当我们学习并熟悉一种求解混合整数问题的技巧时,可以用这种技巧来求解旅行商问题或者背包问题,以此来验证自己对该技巧的掌握程度. 目录 什么是旅行商问题 旅行商问题的数学模型 什么是旅行商问题 定义 Given a list of cities and the distances between each pair of cities, what is the sh…

We began our study of algorithmic techniques with greedy algorithms, which in some sense form the most natural approach to algorithm design. Faced with a new computational problem, we've seen that it's not hard to propose multiple possible greedy alg…
