Cross back discover undirected graphs
Did you know?
WebAn undirected graph is acyclic (i.e., a forest) if and only if a DFS yields no back edges. If there’s a back edge, there’s a cycle. If there’s no back edge, then by Theorem 22.10, there are only tree edges. Hence, the graph is acyclic. Thus, we can run DFS: if we nd a back edge, there’s a cycle. Time: O(V). (Not O(V+ E)!) WebJun 30, 2024 · In the following graph, there are 3 back edges, marked with cross sign. It can be observed that these 3 back edges indicate 3 cycles present in the graph. For a disconnected graph, we get the DFS forest …

WebDec 14, 2024 · Note: A vertex in an undirected connected graph is an articulation point (or cut vertex) if removing it (and edges through it) disconnects the graph. 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.
