WebIt follows that a directed graph is an oriented graph if and only if it has no 2-cycle. (This is not the only meaning of "oriented graph"; see Orientation (graph theory).) Tournaments are oriented graphs obtained by choosing a direction for each edge in undirected complete graphs. Note that a tournament is a semicomplete digraph.
