is_strongly_connected(G)

Test directed graph for strong connectivity.

A directed graph is strongly connected if and only if every vertex in the graph is reachable from every other vertex.

Parameters

G (NetworkX Graph) – A directed graph.

Returns

connected – True if the graph is strongly connected, False otherwise.

Return type

bool

Raises

NetworkXNotImplemented – If G is undirected.
