While there is nothing special about the order of the nodes within each strongly connected component, one useful property of the algorithm is that no strongly connected component will be identified before any of its successors. Therefore, the order in which the strongly connected components are identified constitutes a reverse topological sort of the DAG formed by the strongly connected components.

How to reduce a strongly connected component to one vertex?

WebA strongly connected component (SCC) of a directed graph G = (V;E) is a maximal set of vertices such that any two vertices in the set are mutually reachable. Example: All vertices along a directed cycle are in the same SCC. Intuitively, we think of a SCC as a cycle. Given a directed graph, some questions that one may be interested in are: WebWhy? In a SCC, there is a path from every vertex to every other vertex in the same SCC. If the graph has a single SCC then every intersection has a route to every other intersection. The SCC algorithm takes linear time O(n + m) for its two runs of DFS, as required.
