WebTarjan's Algorithm is popular algorithm for finding the Strongly Connected Components (SCC) of a directed graph. In the below graph, the nodes in a blue envelope constitute a single connected component as any node u u as a path to another node v v and vice versa. Note that while we can reach the node f f from the node e e, the opposite is not true. WebDec 14, 2024 · Articulation points represent vulnerabilities in a connected network – single points whose failure would split the network into 2 or more components. They are useful for designing reliable networks. For a disconnected undirected graph, an articulation point is a vertex removal which increases the number of connected components.
