Strategyproof cost-sharing mechanisms for set cover and facility location games
Strategyproof cost-sharing mechanisms, lying in the core, that recover 1/? fraction of the cost, are presented for the set cover and facility location games: ?=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.
