We would like to thank our sponsors for their generous support of this event. This conference is concerned with all aspects of computing with constraints, including:theory,algorithms,applications,environments,languages,modelsand systems. We received a wide variety of submissions, each of which was reviewed by at least three referees. Referees were chosen for each submission by an initial bidding process where Program Committee members chose papers from their area of interest. The range of expertise represented by the large ProgramCom- mittee meant that almost all submissions were reviewed by subject experts on the Program Committee, or by colleagues chosen by members of the Program Committeefortheirparticularexpertise.Papersweresolicitedeitheraslong(15 page), or short (8 page) submissions. Short-paper submissions were refereed to exactly the same high standards as long-paper submissions but naturally were expectedtocontainasmallerquantityofnewmaterial.Thusthereisnodistinc- tion in these proceedings between short and long papers. I used the excellent EasyChairconference managementsystem to support this process of reviewing, and for the collation and organization of these proceedings. Submissions were made either to the applications track or to the research track.Therewere101(23short)researchtracksubmissionsofwhich36(8short) wereaccepted,whichisa36%(35%ofshort)acceptancerate.Applicationstrack submissions received special consideration and the acceptance rate was signifi- cantly higher than for the research track. There were 21 (2 short) applications track submissions of which 11 (1 short) were accepted for a 52% (50% of short) acceptance rate. Therewerethreeinvitedtalksfromdistinguishedscientists:RobertNieuwen- huis, Edward Tsang and Moshe Vardi. These proceedings include abstracts of eachoftheirpresentations.Detailsofthewidevarietyofworkshopsandthefour tutorials that took place as part of the conference are also included. I would like to thank the Association for Constraint Programming (ACP) for inviting me to be Program Chair. It has been a rewarding experience, not only because of the high quality of the papers submitted, but also for the help so readily given to me by friends and colleagues around the world. I want to thank all of the authors for submitting such interesting papers. It istheir hardworkthatmakesthe conferencesointeresting,butthe highquality of the submissions also makes the decisionprocess challenging.I would also like to thank the members of the Program Committee for agreeing to help in the VI Preface first place, and for the excellent standardof reviewing.My particular thanks go to those people who providedfourth reviews when decisions were most difficult. Several people deserve special mention. Karen Petrie, who, as Conference Chair, saved my life on many occasions. Ian Gent, who, as the Program Chair for CP 2009, was a source of invaluable information, warnings and good ad- vice. Barry O’Sullivan for his speedy replies to questions, and general support. Peter Stuckey, who was the Applications Track Chair, Pedro Meseguer for the workshop organization, Thomas Schiex for managing the tutorials and Peter Nightingale and Standa Zivny for running the doctoral program. The local Organizing Committee always put in a great deal of work, often unthanked,to make a conference like this successful.Andrea Rendl as Publicity Chair and Neil Moore who ran the website helped me a lot during the build up to CP 2010. September 2010 David Cohen Distinguished Papers The Program Committee chose one paper from the Research Track, one paper fromtheApplicationsTrackandoneStudentPapertoberecognizedasachieving the highest standard submitted in their category.
