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 }.
