UVA.10066 The Twin Towers (DP LCS) 题意分析 有2座塔,分别由不同长度的石块组成.现在要求移走一些石块,使得这2座塔的高度相同,求高度最大是多少. 问题的实质可以转化为LCS(最长公共子序列)问题. 推荐一篇写的比较好的博文: 动态规划求解最长公共子序列(LCS) 核心的状态转移方程: if(a[i] == b[j]) dp[i][j] = dp[i-1][j-1] +1; else dp[i][j] = max(dp[i-1][j],dp[i][j-1]);…

UVA.10192 Vacation (DP LCS) 题意分析 某人要指定旅游路线,父母分别给出了一系列城市的旅游顺序,求满足父母建议的最大的城市数量是多少. 对于父母的建议分别作为2个子串,对其做LCS处理,最后的结果即为所求. 核心状态转移方程: if(c1[i] == c2[j]) dp[i][j] =dp[i-1][j-1]+1; else dp[i][j] = max(dp[i-1][j],dp[i][j-1]); 这里还有一个小技巧,当希望读取的字符数据,不是从字符数组的第0个元素…
