Although 2-opt is widely used in practice, it is hard to understand its success from a theoretical perspective. We take a statistical approach and examine the features of TSP instances that make the problem either hard or easy to solve. As a measure of problem difficulty for 2-opt we use the approximation ratio that it achieves on a given instance. Our investigations point out important features that make TSP instances hard or easy to be approximated by 2-opt.","lang":"eng"}],"publication":"Revised Selected Papers of the 6th International Conference on Learning and Intelligent Optimization - Volume 7219","type":"conference","title":"Local Search and the Traveling Salesman Problem: A Feature-Based Characterization of Problem Hardness","date_created":"2023-11-14T15:58:59Z","author":[{"first_name":"Olaf","last_name":"Mersmann","full_name":"Mersmann, Olaf"},{"first_name":"Bernd","last_name":"Bischl","full_name":"Bischl, Bernd"},{"first_name":"Jakob","full_name":"Bossek, Jakob","id":"102979","last_name":"Bossek","orcid":"0000-0002-4121-4668"},{"first_name":"Heike","full_name":"Trautmann, Heike","last_name":"Trautmann"},{"first_name":"Markus","last_name":"Wagner","full_name":"Wagner, Markus"},{"full_name":"Neumann, Frank","last_name":"Neumann","first_name":"Frank"}],"publisher":"Springer-Verlag","date_updated":"2023-12-13T10:48:58Z","page":"115–129","citation":{"chicago":"Mersmann, Olaf, Bernd Bischl, Jakob Bossek, Heike Trautmann, Markus Wagner, and Frank Neumann. “Local Search and the Traveling Salesman Problem: A Feature-Based Characterization of Problem Hardness.” In <i>Revised Selected Papers of the 6th International Conference on Learning and Intelligent Optimization - Volume 7219</i>, 115–129.
