Greatest Common Increasing Subsequenc Problem Description This is a problem from ZOJ 2432.To make it easyer,you just need output the length of the subsequence.   Input Each sequence is described with M - its length (1 <= M <= 500) and M integer numb…

讲解摘自百度; 最长公共上升子序列(LCIS)的O(n^2)算法? 预备知识:动态规划的基本思想,LCS,LIS.? 问题:字符串a,字符串b,求a和b的LCIS(最长公共上升子序列).? 首先我们可以看到,这个问题具有相当多的重叠子问题.于是我们想到用DP搞.DP的首要任务是什么?定义状态.? 1定义状态F[i][j]表示以a串的前i个字符b串的前j个字符且以b[j]为结尾构成的LCIS的长度.? 为什么是这个而不是其他的状态定义?最重要的原因是我只会这个,还有一个原因是我知道这个定义能搞到平…
