American Association for Artificial Intelligence, 34-41. Menlo Park, C.A.: AAAI Press; Cambridge, M.A.: MIT Press.0-262-51183-5978-0-262-51183-4http://nrs.harvard.edu/urn-3:HUL.InstRepos:4039784We introduce anytime mechanisms for distributed optimization with self-interested agents. Anytime mechanisms retain good incentive properties even when interrupted before the optimal solution is computed, and provide better quality solutions when given additional time. Anytime mechanisms can solve easy instances of a hard problem quickly and optimally, while providing approximate solutions on very hard instances. In a particular instantiation, GROWRANGE, we successively expand the range of outcomes considered, computing the optimal solution for each range. Truth-revelation remains a dominant strategy equilibrium with a stage-based interruption, and is a best-response with high probability when the interruption is time-based.en-USMonograph or Book2010-05-03
