You can take a non-recursive DFS algorithm for detecting cycles in undirected graphs where you replace the stack for the nodes by a queue to get a BFS algorithm. It's straightforward: q <- new queue // for DFS you use just a stack append the start node of n in q while q is not empty do n <- remove first element of … WebA path that starts from a given vertex and ends at the same vertex traversing the edges only once is called a cycle. In the below graph, there exists a cycle between vertex 1, 2 and 3. 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.

When we do a Breadth–first search (BFS) from any vertex v in an undirected graph, we may encounter a cross-edge that points to a previously discovered vertex that is neither an ancestor nor a descendant of the current vertex. Each “cross edge” defines a cycle in an undirected graph. If the cross edge is x —> y, then since y ...
