WebIn graph theory, the weak components of a directed graph partition the vertices of the graph into subsets that are totally ordered by reachability. ... relation is an equivalence … WebOct 10, 2024 · A Strongly Connected Component of a graph G is a subset C of the vertices so that. Every vertex in C has a path in G to every other vertex in C (so C is strongly connected) If we add any new vertices to C, say C ∪ { v 1, …, v n }, then we get something that isn't strongly connected (so C is maximal). See, for instance, the wikipedia page ...

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.
