WebAug 9, 2024 at 18:23. @ElleryL, I'm pretty sure this is true for an undirected graph. In an undirected graph, BFS should only produce tree edges and cross edges. Cross edges will always be produced if there are cycles in the undirected graph (i.e. m ≥ n ). This is similar to how dfs on undirected graph produces only tree edges and back edges. WebDec 15, 2024 · Like directed graphs, we can use DFS to detect a cycle in an undirected graph in O (V+E) time. We have discussed DFS based solution for cycle detection in an undirected graph .

WebJul 28, 2024 · An undirected graph is a set of nodes and edges, such that an edge signifies bidirectionality. Any path with 1 or more duplicates of any node(s) present in the path is known as a cycle A graph containing a cycle is called cyclic. We can solve the problem of detecting a cycle in an undirected graph by using dfs or bfs. WebMar 20, 2024 · The cycle in a graph can be detected using graph traversal algorithms.
