WebStrongly Connected Components 1 Connected components in undirected graphs A connected component of an undirected graph G = (V,E) is a maximal set of vertices S ⊂V such that for each u ∈S and v ∈S, there exists a path in G from vertex u to vertex v. Definition 1 (Formal Definition). Let u ∼v if and only if G has a path from vertex u to ... WebA connected graph is an undirected graph in which every unordered pair of vertices in the graph is connected. Otherwise, it is called a disconnected graph . In a directed graph, an ordered pair of vertices (x, y) is called strongly connected if a directed path leads from x to y.

WebStep 2: Connected components as if in an undirected graph Start at A and use the post number of Step 1 to break ties (highest post So we travel from A to B. So, we visit D. the stack, and so create D as a strongly connected component. We then pop D from the stack, add D to the list of already visited strongly connected components, and return to B.
