This book constitutes the refereed proceedings of the 6th International
Conference on Integration of AI and OR Techniques in Constraint Programming for
Combinatorial Optimization Problems, CPAIOR 2009, held in Pittsburgh, PA, USA,
in May 2009.
The 20 revised full papers and 10 extended abstracts presented together with 2
invited talks were carefully reviewed and selected from 65 submissions. The
papers describe current research in the fields of constraint programming,
artificial intelligence, and operations research and present new techniques or
new applications in combinatorial optimization, thus exploring ways of solving
large-scale, practical optimization problems through integration and
hybridization of the fields' different techniques.
