Recent Advances in Constraints - 12th Annual ERCIM International Workshop on Constraint Solving and Contraint Logic Programming, CSCLP 2007 Rocquencourt, France, June 7-8, 2007 Revised Selected Papers (Paperback, 2008 ed.)

Constraint programming supports a great ambition for computer programming: the one of making programming essentially a modeling task, with equations, constraints, and logicalformulas. This ?eld emerged in the mid-1980sborrowing conceptsfromlogicprogramming, operationsresearch, andarti?cialintelligence. Its foundation is the use of relations on mathematical variables to compute with partial information systems. The successes of constraint programming for so- ing combinatorial optimization problems in industry or commerce are related to the advances made in the ?eld on new constraint propagationtechniques and on declarativelanguageswhich allowcontrolonthe mixing of heterogeneousreso- tiontechniquessuchasnumerical, symbolic, deductive, andheuristictechniques. This volumecontainsthe papers selectedfor the post-proceedingsof the12th International Workshop on Constraint Solving and Constraint Logic Progr- ming (CSCLP 2007) held during June 7-8, 2008 in Rocquencourt, France. This workshop, open to all, was organized as the 12th meeting of the working group onConstraintsofthe EuropeanResearchConsortiumfor Informaticsand Ma- ematics (ERCIM), continuing a series of workshops organized since the creation of the working group in 1997. A selection of papers of these annual workshops have been published since 2002 in a series of books which illustrate the evo- tion of the ?eld, under the title "Recent Advances in Constraints"in the Lecture Notes in Arti?cial Intelligence series. This year, there were 16 submissions, most of them being extended and - vised versions of papers presented at the workshop, plus some new papers. Each submission was reviewed by three reviewers. The Program Committee decided to accept ten papers for publication in this book.
