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 …
WebCycles find_cycle find_cycle # find_cycle(G, source=None, orientation=None) [source] # Returns a cycle found via depth-first traversal. The cycle is a list of edges indicating the cyclic path. Orientation of directed edges is controlled by orientation. Parameters: Ggraph A directed/undirected graph/multigraph. sourcenode, list of nodes 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
