ap :: Graph gr => gr a b -> [Node] | |||||

Finds the articulation points for a connected undirected graph, by using the low numbers criteria: a) The root node is an articulation point iff it has two or more children. b) An non-root node v is an articulation point iff there exists at least one child w of v such that lowNumber(w) >= dfsNumber(v). | |||||
