Generate nodes in strongly connected components of graph.
G : NetworkX Graph
An directed graph.
comp : generator of lists
A list of nodes for each strongly connected component of G.
NetworkXNotImplemented: If G is undirected.
Uses Tarjan’s algorithm with Nuutila’s modifications. Nonrecursive version of algorithm.
