The Traveling Salesrep Problem, Edge Assembly Crossover, and 2-opt

- Summary
- Metrics

Abstract

Optimal results for the Traveling Salesrep Problem have been reported on problems with up to 3038 cities using a GA with Edge Assembly Crossover (EAX). This paper first attempts to independently replicate these results on Padberg's 532 city problem. We then evaluate the performance contribution of the various algorithm components. The incorporation of 2-opt into the EAX GA is also explored. Finally, comparative results are presented for a population-based form of 2-opt that uses partial restarts.
