A Novel Particle Swarm Optimization-Based Algorithm for the Graph Coloring Problem

In this paper, we study the problem of graph coloring and propose a novel particle swarm optimization (PSO) algorithm for it. We use the PSO evolutionary progress to improve a simple deterministic greedy algorithm. The new algorithm can achieve a result that is better than known heuristic algorithms do, as verified by an extensive simulation study. ©2009 IEEE.
