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.

WebNov 8, 2024 · 1 Answer. The idea is that if we find a cycle in G, then we can orient its edges so that the nodes in the cycle will be all strongly connected. The cycle can then be collapsed into a single node. If the graph had no bridges the new graph will also have no bridges and this procedure can be repeated.

A directed graph is weakly connected (or just connected ) if the undirected underlying graph obtained by replacing all directed edges of the graph with undirected edges is a connected graph. A directed graph is strongly connected or strong if it contains a directed path from x to y (and from y to x) for every pair of vertices (x, y). The strong components are the maximal strongly connected subgraphs. WebStrongly connected components also have a use in other graph algorithms: if you replace every strongly connected component by a single vertex, you get a smaller directed acyclic graph, known as the component graph or condensation (Baase ex. …
