# Tournament¶

Functions concerning tournament graphs.

A tournament graph is a complete oriented graph. In other words, it is a directed graph in which there is exactly one directed edge joining each pair of distinct nodes. For each function in this module that accepts a graph as input, you must provide a tournament graph. The responsibility is on the caller to ensure that the graph is a tournament graph.

To access the functions in this module, you must access them through the networkx.algorithms.tournament module:

>>> import networkx as nx
>>> from networkx.algorithms import tournament
>>> G = nx.DiGraph([(0, 1), (1, 2), (2, 0)])
>>> tournament.is_tournament(G)
True

 hamiltonian_path(G) Returns a Hamiltonian path in the given tournament graph. is_reachable(G, s, t) Decides whether there is a path from s to t in the tournament. is_strongly_connected(G) Decides whether the given tournament is strongly connected. is_tournament(G) Returns True if and only if G is a tournament. random_tournament(n[, seed]) Returns a random tournament graph on n nodes. score_sequence(G) Returns the score sequence for the given tournament graph.
