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. WebJun 16, 2024 · The Depth-First Search (DFS) is a graph traversal algorithm. In this algorithm, one starting vertex is given, and when an adjacent vertex is found, it moves to that adjacent vertex first and tries to traverse in the same manner. It moves through the whole depth, as much as it can go, after that it backtracks to reach previous vertices to …
