题意:在n*m的方格里铺1*2的骨牌,有多少种方案 /* 第一次做插头DP,感觉和状压差不多. 这道题是利用上一行的状态来更新下一行的状态. 1代表上一行这个位置填了一个竖的(即本行可以填): 0代表填了一个横的或者是竖的方格的第二行(即本行可以填). */ #include<cstdio> #include<iostream> #include<cstring> #define N 12 using namespace std; int n,m; <<N]…

[POJ2411]Mondriaan's Dream(轮廓线DP) 题面 Vjudge 题解 这题我会大力状压!!! 时间复杂度大概是\(O(2^{2n}n^2)\),设\(f[i][S]\)表示当前第\(i\)行向下伸展出去的状态为\(S\) 那么每次枚举一下当前行的放法,进行转移就好了. 然后就长成了这个样子(不要在意我强行缩减代码长度) 尽管这不是我们本题的重点,然而我还是放份代码 #include<cstdio> #include<cstring> int n,m;long…

题意:有一个n*m的棋盘,要求用1*2的骨牌来覆盖满它,有多少种方案?(n<12,m<12) 思路: 由于n和m都比较小,可以用轮廓线,就是维护最后边所需要的几个状态,然后进行DP.这里需要维护的状态数就是min(n,m).即大概是一行的大小.每次放的时候,只考虑(1)以当前格子为右方,进行横放:(2)以当前格子为下方进行竖放:(3)还有就是可以不放. 3种都是不一样的,所以前面的一种状态可能可以转为后面的几种状态,只要满足了条件.条件是,横放时,当前格子不能是最左边的:竖放时,当前格子不能是…
