WebGraph Coloring Problem. Graph coloring (also called vertex coloring) is a way of coloring a graph’s vertices such that no two adjacent vertices share the same color. This post will discuss a greedy algorithm for graph coloring and minimize the total number of colors used. We can color it in many ways by using the minimum of 3 colors.
