The traditional, serial, algorithm for finding the strongly connected components in a graph is based on depth first search and has complexity which is linear in the size of the graph. Depth first search is difficult to parallelize, which creates a need for a different parallel algorithm for ...
Strongly Connected in Graph强连通 In the mathematical theory of directed graphs, a graph is said to be strongly connected or diconnected if every vertex is reachable from every other vertex. 有向图强连通分量的Tarjan算法 (“郭家寶”,个人网站byvoid.com 的页面 强烈推荐大神的博客) 直接根据定义,用...

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 the following graph. 有向图的强连通分量(St...

We denote with SCC(G) the set of strongly connected components of G . These strongly connected components do not intersect with each other, and cover all vertices in the graph. Thus, the set SCC(G) is a partition of V . Consider this graph ...
