题目链接:http://acm.zju.edu.cn/onlinejudge/showProblem.do?problemCode=2182 题意:给出一个无向图,问最少删掉多少个顶点之后图变得不连通? 思路:将原图每个点拆点(i,i+n),连边<i,i+n,1>,对原图的边(u,v),连边<u+n,v,INF>,<v+n,u,INF>.然后对于每对顶点(i,j)跑最大流(i+n,j).所有最大流的最小值即为答案. struct node { int v,cap,nex…

无向图顶点连通度的求解,即最少删除多少个点使无向图不连通. 我校“荣誉”出品的<图论算法理论.实现及其应用>这本书上写的有错误,请不要看了,正确的是这样的: 对于每个顶点,分成两个点,v和v’: 对于每个顶点,v到v’建边,容量为1: 对于无向边(u,v),建边<u’,v>和<v’,u>容量为+∞: 然后枚举每一对没有边直接相连的点对(x,y),x’为源点,y为汇点,跑最大流.最大流的最小值即为答案. #include<cstdio> #include<…
