IsOriented(G)

-
directed graph
IsOriented(G) returns true if G is a directed graph containing no symmtric pair of arcs. That is, for every pair of vertices u and v in G, at most one of the arcs [u,v] and [v,u] is in G.
Since a pair of symmetric arcs forms a directed cycle, every acyclic directed graph is oriented.
The GraphTheory[IsOriented] command was introduced in Maple 2022.
