[POJ 1080] Human Gene Functions 相似于最长公共子序列的做法 dp[i][j]表示 str1[i]相应str2[j]时的最大得分 转移方程为 dp[i][j]=max(dp[i-1][j-1]+score[str1[i]][str2[j]], max(dp[i-1][j]+score[str1[i]]['-'],dp[i][j-1]+score['-'][str2[j]]) ) 注意初始化0下标就好 代码例如以下: #include <iostream> #inc…

Color Length(UVA-1625)(DP LCS变形) 题目大意 输入两个长度分别为n,m(<5000)的颜色序列.要求按顺序合成同一个序列,即每次可以把一个序列开头的颜色放到新序列的尾部. https://odzkskevi.qnssl.com/a68cbd3e27f46b4f02ea12b7b1a1abca 然后产生的新序列中,对于每一个颜色c,都有出现的位置,L(c)表示最小位置和最大位置之差,求L(c)总和最小的新序列. 分析 LCS 是公共上升子序列,在动态转移的过程中,考虑…
