Abstract
Abstract:This Thesis deals with the development of a Swarm Intelligence algorithm to solve theclassical problem of Graph Coloring. The Gravitational Swarm for Graph Coloring(GS-GC) algorithm maps the GCP problem into a collection of autonomous agents thatmove in a space following a global gravitational attraction to the color goals andattraction-repulsion local forces corresponding to the graph topology. The Thesisprovides formal asymptotic convergence proofs showing that the GS-GC stationarystates correspond to GCP solutions. The Thesis provides also extensive empiricalsupport of the GS-GC comparing it with state of the art algorithms.
