strongly_connected_components_recursive

strongly_connected_components_recursive(G)

Return nodes in strongly connected components of graph.

Recursive version of algorithm.

Parameters :

G : NetworkX Graph

An directed graph.

Returns :

comp : list of lists

A list of nodes for each component of G. The list is ordered from largest connected component to smallest.
