An algorithm is presented which finds all the elementary circuits-of a directed graph in time bounded by O ( (n + e) (c + 1)) and space bounded by O (n + e), where there are n vertices, e edges and c … WebJan 31, 2024 · For each node in the queue, mark it as visited, and iterate through all the nodes that are connected to it (using the adjacency list), and decrement the degree of each of those nodes by one in the map. Add all nodes whose degree becomes equal to one to the queue. At the end of this algorithm, all the nodes that are unvisited are part of the cycle.
WebMar 22, 2024 · To find cycle in a directed graph we can use the Depth First Traversal (DFS) technique. It is based on the idea that there is a cycle in a graph only if there is a back edge [i.e., a node points to one of its ancestors] present in the graph.
