题目描述: 数据范围:2<=n,m<=8 题解: 很明显需要状压.但是怎么压不知道,压什么不知道. 然后从条件下手. 条件1要求黑色在一起白色在一起,记录轮廓线很容易做到. 条件2要求不能出现$2*2$的同色方格.我们还需要再记录当前位置的左上角. 所以这道题的轮廓线长这样. 丑图. 我们需要确定一个顺序记录哪几块互相联通.由于轮廓线奇特的形状我决定这样标号. 如果编号相同但是并不互相联通我们可以知道他俩不同颜色. 为了颜色我们决定记录某个块的颜色,这样可以得到所有颜色. 于是这道题表中存的就…

解题思路: 分类讨论即可. 代码(懒得删Debug了): #include<map> #include<cstdio> #include<vector> #include<cstring> #include<algorithm> #define black '#' #define white 'o' #define BLACK_AND_WHITE int main(){/*freopen("a.in","r"…

Matlab expects images of type double to be in the 0..1 range and images that are uint8 in the 0..255 range. You can convert the range yourself (but change values in the process), do an explicit cast (and potentially loose precision) or instruct Matla…

题目大概说有几个黑色.白色矩阵,问能选出黑白不相交的矩形面积和的最大值. 建二分图,黑色矩阵为X部的点,白色为Y部,XY的点权都为其矩阵面积,如果有个黑白矩阵相交则它们之间有一条边,那样问题就是要从这个二分图中选出最大的点使其没有公共边且点权和最大. 即二分图的最大点权独立集.可以建容量网络用最小割求解,在二分图基础上加源点汇点,源点向X部连容量为权值的边,Y部向汇点连容量为权值的边,X部与Y部的无向边改为容量INF的有向边,最后的结果就是所有点权和-最小割. #include<cstdio>…
