A connected component is a maximal connected subgraph of an undirected graph. Each vertex belongs to exactly one connected component, as does each edge. A graph is connected if and only if it has exactly one connected component. The strong components are the maximal strongly connected subgraphs of a directed graph. A vertex cut or separating set of a connected graph G is a set of vertices whose removal render… WebFeb 24, 2024 · A directed graph is strongly connected if there is a path between any two pairs of vertices. There are different methods to check the connectivity of directed graph but one of the optimized method is Kosaraju’s DFS based simple algorithm . Kosaraju’s BFS based simple algorithm also work on the same principle as DFS based algorithm does.
