Decides whether the given tournament is strongly connected.
This function is more theoretically efficient than the
The given graph must be a tournament, otherwise this function’s behavior is undefined.
- GNetworkX graph
A directed graph representing a tournament.
Whether the tournament is strongly connected.
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 .
