WebAug 8, 2024 · Spanning Tree: A spanning tree T of an undirected graph G is a sub-graph that is a tree which includes all of the vertices of G. This algorithm is intended to find all the cycles in the graph that have the least overlap. If we have a graph [ABCD] the cycles returned by the algorithm will be [ABD] and [BCD]. The cycle [ABCD] will not be returned. WebLet's use the Union-Find algorithm to find cycle in an undirected graph.
