A Cooperative Search Method for the k-Coloring Problem

Author:
Hend Bouziri   El-Ghazali Talbi and Khaled Mellouli  


Journal:
Journal of Mathematical Modelling and Algorithms


Issue Date:
2008


Abstract(summary):

In this paper, a cooperative search method, based on a multi-agent structure is developed to deal with the k-coloring problem. Three agents coordinate using an adaptive memory, a search agent, an intensification agent and a diversification agent. We use the results of a preliminary fitness landscape study to adjust the navigation strategy in the solution space and to fix the search parameters. Our method provides competitive results and it is fast when compared with best existing techniques on instances extracted from the second DIMACS challenge.
