Heuristic methods for graph coloring problems

Abstract

In this work, the Graph Coloring Problem and its generalizations - the Bandwidth Coloring Problem, the Multicoloring Problem and the Bandwidth Multicoloring Problem - are studied. A Squeaky Wheel Optimization with Tabu Search heuristic is developed and experiments using benchmark geometric test cases show that the algorithm performs well for these problems and achieves results for the Bandwidth Multicoloring Problem which improve on results obtained by other researchers.
