题目链接:QAQ 大致题意:有一个m行n列的矩阵,用1*2的骨牌(可横放或竖放)完全覆盖,骨牌不能重叠,有多少种不同的覆盖的方法? Solution: \(n,m\le11\),肯定是不能暴力的,又类似棋盘问题,一下就能想到状压dp 对于每一列(或每一行)的状态用二进制表示,0表示放了,1表示没放,在转换回十进制存储. 然后枚举一列的所有状态,看它可以转移到哪些状态,然后统计答案就行了. 最后应该输出f[n+1][0],而不是f[n][n].本题需要long long. Code: #inclu…

题目:Mondriaan's Dream 链接:http://poj.org/problem?id=2411 题意:用 1*2 的瓷砖去填 n*m 的地板,问有多少种填法. 思路: 很久很久以前便做过的一道题目,状压DP,当时写得估计挺艰辛的,今天搜插头DP又搜到它,就先用状压DP写了下,顺利多了,没一会就出来了,可惜因为long long没有1A. 思路挺简单,一行一行解决,每一列用1 表示对下一行有影响,用0 表示对下一行没有影响,所以一行最多2048 种可能,然后要筛选一下,因为有些本身就…

[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…
