How to detect cycle in undirected graph
WebTo find the nodes forming the cycle, eliminate all nodes with degree 1, until only the nodes with degree 2 remain. These are the nodes that will form the cycle. This inituition is the underlying logic that we are going to apply to detect cycle and the vertices forming the cycle. Algorithm WebAdd a comment. 4. Make sure that you understand what DFS is doing and why a back-edge means that a graph has a cycle (for example, what does this edge itself has to do with the …

WebJun 16, 2024 · To detect if there is any cycle in the undirected graph or not, we will use the DFS traversal for the given graph. For every visited vertex v, when we have found any … WebFirst, let us find all cycles in the graph. Then, we will filter out the ones that contain chords; this we can detect by checking if the n -vertex induced subgraph is isomorphic to a cycle of length n or not. Let us use your graph as an example:
