Towards Better Inapproximability Bounds for TSP: A Challenge of Global Dependencies
نویسنده
چکیده
We present in this paper some of the recent techniques and methods for proving best up to now explicit approximation hardness bounds for metric symmetric and asymmetric Traveling Salesman Problem (TSP) as well as related problems of Shortest Superstring and Maximum Compression. We attempt to shed some light on the underlying paradigms and insights which lead to the recent improvements as well as some inherent obstacles for further progress on those problems.

Improved Inapproximability Results for the Shortest Superstring and the Bounded Metric TSP
We present a new method for proving explicit approximation lower bounds for the Shortest Superstring problem, the Maximum Compression problem, Maximum Asymmetric TSP problem, the (1, 2)–ATSP problem, the (1, 2)–TSP problem, the (1, 4)–ATSP problem and the (1, 4)–TSP problem improving on the best up to now known approximation lower bounds for those problems.

متن کاملNew Inapproximability Bounds for TSP
In this paper, we study the approximability of the metric Traveling Salesman Problem (TSP) and prove new explicit inapproximability bounds for that problem. The best up to now known hardness of approximation bounds were 185/184 for the symmetric case (due to Lampis) and 117/116 for the asymmetric case (due to Papadimitriou and Vempala). We construct here two new bounded occurrence CSP reduction...
متن کاملApproximation hardness of graphic TSP on cubic graphs
We prove explicit approximation hardness results for the Graphic TSP on cubic and subcubic graphs as well as the new inapproximability bounds for the corresponding instances of the (1,2)-TSP. The proof technique uses new modular constructions of simulating gadgets for the restricted cubic and subcubic instances. The modular constructions used in the paper could be also of independent interest.
متن کاملOn Approximability of Bounded Degree Instances of Selected Optimization Problems
In order to cope with the approximation hardness of an underlying optimization problem, it is advantageous to consider specific families of instances with properties that can be exploited to obtain efficient approximation algorithms for the restricted version of the problem with improved performance guarantees. In this thesis, we investigate the approximation complexity of selected NP-hard opti...
