Strategyproof cost-sharing mechanisms for set cover and facility location games

Abstract

Strategyproof cost-sharing mechanisms, lying in the core, that recover 1/a fraction of the cost, are presented for the set cover and facility location games: a=O(log n) for the former and 1:861 for the latter. Our mechanisms utilize approximation algorithms for these problems based on the method of dual-fitting. D 2004 Elsevier B.V. All rights reserved.
