networkx.algorithms.tournament.is_strongly_connected¶
-
is_strongly_connected
(G)[source]¶ Decides whether the given tournament is strongly connected.
This function is more theoretically efficient than the
is_strongly_connected()
function.The given graph must be a tournament, otherwise this function’s behavior is undefined.
- Parameters
G (NetworkX graph) – A directed graph representing a tournament.
- Returns
Whether the tournament is strongly connected.
- Return type
Notes
Although this function is more theoretically efficient than the generic strong connectivity function, a speedup requires the use of parallelism. Though it may in the future, the current implementation does not use parallelism, thus you may not see much of a speedup.
This algorithm comes from [1].
