PDF-Directed Graphs What is a directed graph Directed Graph directed graph or digraph consists

We call the tail of the head of and uv the ends of If there is an edge with tail and head then we let uv denote such an edge and we say that this edge is directed from to Loops Parallel Edges and Simple Digraphs An edge uv in a digraph is a. . . .
