Greedy coloring

Greedy coloring is a graph coloring algorithm used to assign colors to the vertices of a graph such that no two adjacent vertices share the same color. The goal of graph coloring is to minimize the number of colors used, and greedy coloring serves as a heuristic method for this purpose. ### Basic Procedure The greedy coloring algorithm typically follows these steps: 1. **Order the Vertices**: Start by ordering the vertices of the graph.
