Abstract

We study exact algorithms for Metric TSP in . In the early 1990s, algorithms with running time were presented for the planar case, and some years later an algorithm with running time was presented for any . Despite significant interest in subexponential exact algorithms over the past decade, there has been no progress on Metric TSP, except for a lower bound stating that the problem admits no algorithm unless ETH fails. In this paper we settle the complexity of Metric TSP, up to constant factors in the exponent and under ETH, by giving an algorithm with running time .

Euclidean TSP的ETH-Tight精确算法
我们研究了度量TSP的精确算法。在20世纪90年代初,针对平面情况提出了具有运行时间的算法,几年后,针对任何情况提出了具有运行时间的算法。尽管在过去的十年里,人们对亚指数精确算法有了很大的兴趣,但在度量TSP上没有任何进展,除了一个下界,即除非ETH失败,否则该问题不允许算法。本文给出了一种具有运行时间的算法,解决了度量TSP的复杂度,使其在指数和ETH下达到常数因子。
