Abstract

David Applegate, Bob Bixby, Bill Cook, and I have written a computer code, available at http://www.keck.caam.rice.edu/concorde.html for solving instances of the traveling salesman problem and used in 1998 to solve a geographical instance with 13,509 cities. One part of the code consists of cutting-plane heuristics inspired by data structures from computer science such as the minimum prefix trees and PQ-trees. This is the part that I will talk about.
