WebDFS of Graph. You are given a connected undirected graph. Perform a Depth First Traversal of the graph. Note: Use a recursive approach to find the DFS traversal of the … 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.

WebWe can easily find the root vertex in O (n + m) time using a DFS. The idea is to start a DFS procedure from any node of the graph and mark the visited vertices. If there are any unvisited vertices, start the DFS again until all vertices are visited. Finally, the vertex having the maximum departure time in DFS is a candidate for the root vertex.
