Abstract

Graph theory is a branch of mathematics that explores the relationships and connections between objects. These objects represented as vertices or nodes are connected by edges. In graph theory, graph coloring is an assignment of labels traditionally called “colors†to elements of a graph subject to certain constraints. In its simplest form it is a way of coloring the vertices of a graph such that no two adjacent vertices are of the same color; this is called vertex coloring. Similarly, edge coloring and face coloring are defined.
