Slightly Improved Upper Bound on the Integrality Ratio for the Path TSP

arXiv:2004.07217

Abstract

In this paper we investigate the integrality ratio of the standard LP relaxation for the metric Path TSP. We make a near-optimal choice for an auxiliary function used in the analysis of Traub and Vygen which leads to an improved upper bound on the integrality ratio of 1.5273.
