WebMay 2, 2024 · That only represents a cycle if the corresponding edge had not yet been travelled before. One way to make the algorithm work, is to store the edge on the stack, not just a node. Then you can easily check if a neighbor is the other end of the edge, and then just ignore it: def find_cycle (graph, start): colors = { node : "WHITE" for node in ... WebA path that starts from a given vertex and ends at the same vertex traversing the edges only once is called a cycle. Example : In the below graph, there exists a cycle between vertex 1, 2 and 3. Note: 1. There are no parallel edges between two vertices. 2. There are no self-loops(an edge connecting the vertex to itself) in the graph. 3.
WebDec 15, 2024 · Like directed graphs, we can use DFS to detect a cycle in an undirected graph in O (V+E) time. We have discussed DFS based solution for cycle detection in an undirected graph . In this article, the BFS based solution is discussed. We do a BFS traversal of the given graph. For every visited vertex ‘v’, if there is an adjacent ‘u’ such ...

WebDec 16, 2010 · Regarding your method to detect cycles in undirected graph, consider 2----1. If I start BFS from 1 I will begin by marking it as visited and add it to the queue. Then, in the while loop, I will retrieve it from the queue and mark any adjacent unvisited vertices as visited and add them to the queue. in other words, I will add 2 to the queue.
