Integration of AI and OR Techniques in Constraint Programming for Combinatorial Optimization Problems

The 7th International Conference on Integration of AI and OR Techniques in Constraint Programming for Combinatorial Optimization Problems (CPAIOR 2010) was held in Bologna, Italy, June 16-18, 2010. The conference is intended primarily as a forum to focus on the integration and hybridization of the approaches of constraint programming (CP), arti?cial intelligence (AI), and operations research (OR) technologies for solving lar- scale and complex real-life combinatorial optimization problems. CPAIOR is focused on both theoretical and practical, application-oriented contributions. The interest of the researchcommunity in this conference is witnessed by the highnumber ofhigh-qualitysubmissions receivedthis year,reaching39 long and 33 short papers. From these submissions, we chose 18 long and 17 short papers to be published in full in the proceedings. ThisvolumeincludesextendedabstractsoftheinvitedtalksgivenatCPAIOR. Namely, one by Matteo Fischetti (University of Padova) on cutting planes and their use within search methods; another by Carla Gomes (Cornell University) on the recently funded NSF Expedition in Computing grant on the topic of computationalsustainabilityandonthepotentialapplicationofhybridoptimi- tion approachesto this area;a third by Peter Stuckey (University of Melbourne) on the integration of SATis?ability solvers within constraint programming and integer programming solvers.

Klappentext

This book constitutes the refereed proceedings of the 7th International Conference on Integration of AI and OR Techniques in Constraint Programming for Combinatorial Optimization Problems, CPAIOR 2010, held in Bologna, Italy, in June 2010. The 18 revised full papers and 17 revised short papers presented together with the extended abstracts of 3 invited talks were carefully reviewed and selected from 72 submissions. The papers are focused on both theoretical and practical, application-oriented issues and present current research with a special focus on the integration and hybridization of the approaches of constraint programming, artificial intelligence, and operations research technologies for solving large scale and complex real life combinatorial optimization problems.
