WebDec 16, 2010 · 6. Just in case, DFS is much more suitable for the task, even more so in directed graphs. If you already knew that, ignore this. As for the pseudocode, well, in an undirected graph, it's a traditional BFS that aborts and reports a cycle found when it reaches a node previously marked as visited. You can find pseudocode for BFS here. WebMay 8, 2013 · The definition of cycle she is using seems to imply she wants triangles, but the proposed algorithm makes it appear she is looking for any length cycle. Anyways, even for directed graphs, Asotsky's answer is incorrect since any undirected graph can be made directed by replacing each edge by two directed edges, one going in either direction. te koop huis kessel

WebJan 2, 2024 · Python Program for Detect Cycle in a Directed Graph. Given a directed graph, check whether the graph contains a cycle or not. Your function should return true if the given graph contains at least one cycle, else return false. For example, the following graph contains three cycles 0->2->0, 0->1->2->0 and 3->3, so your function must return … WebApr 12, 2024 · So Union-find algo will give wrong results for directed graphs. No, we cannot use union-find to detect cycles in a directed graph. This is because a directed graph cannot be represented using the disjoint-set (the data structure on which union-find is performed).
