Strongly connected components (SCC) are the maximally connected subgraphs of a directed graph where every node is reachable from every other node (in other words, there exists a path between every node in the subgraph). Neptune Analytics implements this algorithm using a modified multi-step approac...
algorithm@ Strongly Connected Component 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 foll...
Tarjan的极大强连通子图(strongly connected components,SCC)算法基于深度优先遍历(DFS)实现。本文就尝试从深度优先遍历的角度思考一下Tarjan的方法是如何找出SCC的。 深度优先遍历 深度优先遍历可以说是求SCC比较直观的一个途径。例如对于下图来说,我们从A开始遍历,如果能够回到A,那么整个路径就是一个连通分量。例如下图...
A directed graph is called a strongly connected graph if every vertex is reachable from every other vertex. A strongly connected sub-graph with a large number of vertices in a directed graph is called a strongly connected component. The algorithm for strongly connected components is based on the...
On DFS callback, if the previous node is on the stack, then min the current node’s low-link value with the last node’s low-link value. After visiting all neighbors, if the current node started a connected component, then pop nodes off the stack until the current node is reached. ...
The strongly connected components of the above graph are: Strongly connected components You can observe that in the first strongly connected component, every vertex can reach the other vertex through the directed path. These components can be found using Kosaraju's Algorithm. Kosaraju's Algorithm ...

The exit times play a key role in the algorithm, which will become clear when we discuss the following theorem.First, we define the exit time tout[C] of a strongly connected component C as the maximum of the values tout[v] for all v∈C. ...
