Graph theory basics

WebBasic Terms used in Graph Theory. Graph: An abstract mathematical structure, to model pairwise relations between discrete objects. A graph G = ( V , E ) consists of a finite set V ( set of vertices or nodes ) and a set E (set of edges ) of 2-subsets of V. Each edge is a relation ( adjacency ) between two vertices. WebGraph (discrete mathematics) A graph with six vertices and seven edges. In discrete mathematics, and more specifically in graph theory, a graph is a structure amounting to a set of objects in which some pairs of the objects are in some sense "related". The objects correspond to mathematical abstractions called vertices (also called nodes or ...
