WebApr 8, 2024 · A directed path in a graph is a path such that all arrows point in the same direction, e.g. 〈 A, →, B, →, C, →, D 〉. Directed paths have one node with no arrows pointed into it on the path, called the source, and one node with no arrows pointing out of it on the path, called the sink.
