Find Minimum Weight Cycle in an Undirected Graph

WebIn the case of undirected graphs, only O(n) time is required to find a cycle in an n-vertex graph, since at most n − 1 edges can be tree edges. Many topological sortingalgorithms will detect cycles too, since those are obstacles for topological order to exist.
