A Comparison of Several Models for the Hamiltonian p-Median Problem
Artikel i vetenskaplig tidskrift, 2014

The Hamiltonian p-median problem consists of determining p disjoint cycles of minimum total cost covering all vertices of a graph. We present several new and existing models for this problem, provide a hierarchy with respect to the quality of the lower bounds yielded by their linear programming relaxations, and compare their computational performance on a set of benchmark instances. We conclude that three of the models are superior from a computational point of view, two of which are introduced in this article. (C) 2014 Wiley Periodicals, Inc.
