题意:给你一个连通图,问你最多加多少条边,还能保证该图不是强连通图. 对整个图求强连通分量,然后对图缩点,记录一下缩点之后每隔点包含的原来的点的个数,找出最少的那个点,然后对这个点建成完全图,对另外的所有点建成完全图.然后+两个点建边-所有原来的遍就好了. 链接:http://acm.hdu.edu.cn/showproblem.php?pid=4635 #include <iostream> #include <vector> #include <queue> #in…

Write a program to find the strongly connected components in a digraph. Format of functions: void StronglyConnectedComponents( Graph G, void (*visit)(Vertex V) ); where Graph is defined as the following: typedef struct VNode *PtrToVNode; struct VNode…
Strongly Connected Components A directed graph is strongly connected if there is a path between all pairs of vertices. A strongly connected component (SCC) of a directed graph is a maximal strongly connected subgraph. For example, there are 3 SCCs in…

[CF913F]Strongly Connected Tournament 题意:有n个人进行如下锦标赛: 1.所有人都和所有其他的人进行一场比赛,其中标号为i的人打赢标号为j的人(i<j)的概率为$p=a\over b$.2.经过过程1后我们相当于得到了一张竞赛图,将图中所有强联通分量缩到一起,可以得到一个链,然后对每个大小>1的强联通分量重复过程1.3.当没有大小>1的强连通分量时锦标赛结束. 现在给出n,a,b,求期望比赛的场数. $n\le 2000,a<b\le 1000…
