Websimple_cycles(G) [source] #. Find simple cycles (elementary circuits) of a directed graph. A simple cycle, or elementary circuit, is a closed path where no node appears twice. Two elementary circuits are distinct if they are not cyclic permutations of each other. This is a nonrecursive, iterator/generator version of Johnson’s algorithm [1].
