SEE ALSO Graph, Graph::Undirected AUTHOR AND COPYRIGHT Jarkko Hietaniemi [email protected] WebIn graph theory, a cop-win graph is an undirected graph on which the pursuer (cop) can always win a pursuit–evasion game against a robber, with the players taking alternating turns in which they can choose to move along an edge of a graph or stay put, until the cop lands on the robber's vertex. Finite cop-win graphs are also called dismantlable graphs or …

"WebJul 2, 2024 · Generally whether a graph is directed or not is a structural decision. That is, it's determined before you implement anything or represent the graph in code. If you need to examine the data of your graph to know if it's directed or not, you may mean something different by "undirected" than it normal. " - Graph/undirected.pm
