WebSep 13, 2015 · graph_contains_undirected_cycle This function checks a directed_graph for undirected cycles. More Details... #include [top] graph_has_symmetric_edges This function checks if a directed_graph has a pair of nodes with just one edge between them. If so then it does not have symmetric edges. The existence of a cycle in directed and undirected graphs can be determined by whether depth-first search (DFS) finds an edge that points to an ancestor of the current vertex (it contains a back edge). All the back edges which DFS skips over are part of cycles. In an undirected graph, the edge to the parent of a node should not be counted as a back edge, but finding any other already visited vertex will indicate a back edge. In the case of undirected graphs, only O(n) time is requir…
