Detection of a Cycle in an Undirected Graph. 2 Methods to solve this-. DFS. BFS. Let's done with DFS: Algorithm: For every visited vertex v, if there is an adjacent u such that u is already visited and u is not parent of v, then there is a cycle in graph. If we don’t find such an adjacent for any vertex, we say ...

WebFeb 1, 2024 · Time Complexity: O(V + E) where V is the number of vertices and E is the number of edges in the graph. Auxiliary Space: O(V) where V is the number of vertices in the graph. Another Method: Check cycle exists or Not:- For finding the cycle in an undirected graph we use DFS. Use dfs from every unvisited node. WebCycle in undirected graphs can be detected easily using a depth-first search traversal. While doing a depth-first search traversal, we keep track of the visited node’s parent along with the list of visited nodes. During the traversal, if an adjacent node is found visited that is not the parent of the source node, then we have found a cycle in ...
WebFeb 2, 2024 · union-find algorithm for cycle detection in undirected graphs. Find cycle in undirected Graph using DFS: Use DFS from every unvisited node. Depth First Traversal can be used to detect a cycle in a Graph. There is a cycle in a graph only if there is a back edge present in the graph. A back edge is an edge that is indirectly joining a node to ...
