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.

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 ...
