Rather than adopt this worst-case viewpoint, we introduce a new paradigm that seeks to obtain good performance on typical instances through a modification to the branch-and-bound search paradigm. Incentive compatibility in single-dimensional domains requires that an outcome improves monotonically for an agent as the agent's reported value increases. We obtain a monotone search algorithm by coupling an explicit sensitivity analysis on the decisions made during search with a correction to the outcome to ensure monotonicity. Extensive computational experiments on single-minded combinatorial auctions show better welfare performance than that available from existing approximation algorithms. en_US dc.description.sponsorship Engineering and Applied Sciences en_US dc.language.iso en_US en_US dc.publisher ACM Press en_US dc.relation.isversionof doi:10.1145/2229012.2229067 en_US dash.license OAP dc.title Monotone Branch-and-Bound Search for Restricted Combinatorial Auctions en_US dc.type Conference Paper en_US dc.description.version Accepted Manuscript en_US dash.depositing.author Parkes, David C. dc.date.available 2014-03-20T12:30:14Z dc.relation.book Proceedings of the 13th ACM Conference on Electronic Commerce (EC '12) en_US dc.identifier.doi 10.1145/2229012.2229067 * workflow.legacycomments publisher's version has page numbers en_US dash.contributor.affiliated Lai, John Kwang dash.contributor.affiliated Parkes, David
