“就是迭代,被众人说得这么玄乎" “之所以归为优化,是因为动态规划本质是一个systemetic bruce force" “因为systemetic,所以比穷举好了许多,就认为是优化的功绩咯" 不等长活动的安排 活动不等长,安排利用率最高的活动安排. T(n) 不一定是最大,所以,最后要找出Table中的T(1)->T(n)中最大的,即是最优的. 最长递增子序列 给定一个长度为N的数组,找出一个最长的单调自增子序列(不一定连续,但是顺序不能乱). 例如:给定一个长度为…

2018-01-12 22:50:06 一.优化问题 优化问题用数学的角度来分析就是去求一个函数或者说方程的极大值或者极小值,通常这种优化问题是有约束条件的,所以也被称为约束优化问题. 约束优化问题(亦译为受约束的最优化问题)是一类数学最优化问题,它由目标函数以及与目标函数中的变量相关的约束条件两部分组成,优化过程则为在约束条件下最优化(最大化或最小化)目标函数. 经典的优化问题: 最短路问题 旅行商问题(TSP) 装箱问题 调度问题 背包问题 了解并熟练掌握这些经典的优化问题会对以后遇到的新的…

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…
