WebJan 14, 2024 · A digraph is strongly connected if there is a directed path from every vertex to every other vertex. A digraph that is not strongly connected consists of a set of strongly connected components, which … WebFinding the strongly-connected components is thus closely related to finding cycles. We have already seen that we can detect cycles by looking for back edges in a DFS forest. …

Several algorithms based on depth-first search compute strongly connected components in linear time. • Kosaraju's algorithm uses two passes of depth-first search. The first, in the original graph, is used to choose the order in which the outer loop of the second depth-first search tests vertices for having been visited already and recursively explores them if not. The second depth-first search …
