WebDefinitions. A graph G consists of two types of elements: vertices and edges . Each edge has two endpoints, which belong to the vertex set. We say that the edge connects (or joins) these two vertices. The vertex set of G is denoted V (G) , or just V if there is no ambiguity. An edge between vertices u and v is written as { u , v }. WebJan 14, 2024 · A directed graph (or digraph ) is a set of vertices and a collection of directed edges that each connects an ordered pair of vertices. We say that a directed edge points from the first vertex in the pair and points to the second vertex in the pair. We use the names 0 through V-1 for the vertices in a V-vertex graph. Glossary.
