WebFeb 8, 2009 · An undirected graph is acyclic (i.e., a forest) if a DFS yields no back edges. Since back edges are those edges ( u, v) connecting a vertex u to an ancestor v in a depth-first tree, so no back edges means there are only tree edges, so there is no cycle. So we can simply run DFS. If find a back edge, there is a cycle. robert balachandranWebDec 16, 2010 · Regarding your method to detect cycles in undirected graph, consider 2----1.
