WebNow for some more graph terminology. If some edge (u,v) is in graph G, then vertex v is adjacent to vertex u.In a directed graph, edge (u,v) is an out-edge of vertex u and an in-edge of vertex v.In an undirected graph edge (u,v) is incident on vertices u and v.. In Figure 1, vertex y is adjacent to vertex b (but b is not adjacent to y).The edge (b,y) is an out …
