What is Graph Coloring?

What is Graph Coloring?

In graph theory, given a set of vertices and edges connecting them, the Graph Coloring Problem involves assigning ‘colors’ (labels, numbers) to vertices. These colors have to follow one important rule. No two vertices connected by an edge can be of the same color. (This is the Vertex Coloring problem. Similarly there is an edge coloring problem.)

Why the interest in Graph Coloring problems?

It turns out that quite a number of problems in life (from classroom to sports team scheduling, time-tabling, to Sudoku) can be mapped to be Graph Coloring problems. And therefore, modeling a problem as a Graph Coloring problem and learning to solve them become very valuable skills.
