Abstract

In this paper we introduce a technique for building efficient iterated local search procedures. This technique, that we call perturbation, uses global information on TSP instances to speed-up and improve the quality of the tours found by heuristic methods. The experimental results done on up to 100,000 cities, show that our techniques outperform the known methods for iterating local search for very large instances.
