This book constitutes the refereed proceedings of the 17th International Symposium on Practical Aspects of Declarative Languages, PADL 2015, held in Portland, OR, USA, in June 2015.The 10 revised papers presented were carefully reviewed and selected from numerous submissions. The papers cover all forms of declarative concepts, including, functional, logic, constraints, etc.

PADL'00 was co-located with the 27th ACM C- ference on the Principles of ProgrammingLanguages(POPL'00). The event was organized by COMPULOG AMERICAS. Declarativelanguagesbuildonasoundtheoreticalbasisto provideattractive frameworksfor application development. Indeed, these languages havebeen s- cessfully applied to vastly di erent real-worldsituations, ranging from data base management to active networks to software engineering to decision support s- tems, to mention a few examples. One major strength of declarative languages lies in the way work on e cient implementation has allowed programmers to take advantage of their strong theoretical foundations. In fact, new devel- ments in theory and implementation often open up new application areas. On the other hand, as declarative languages are applied to novel problems, a n- ber of interesting research issues arise. Well-known issues include designing for scalability, language extensions for application deployment, and programming environments.Thus, applications are both a cause for and bene t from progress in the theory and implementation of declarative systems. The goal of the International Workshop on Practical Aspects of Declarative Languages (PADL) series is to provide a forum where researchers, practiti- ers, and implementors of declarative languages may exchange ideas on current and novel application areas and on the requirements for eectiv e deployment of declarative systems. This volume contains the proceedings of the year 2000 workshop, held in Boston, Massachusetts, January 17{18, 2000. Thirty-six - persweresubmittedinresponsetothecallforpapers.

This book constitutes the refereed proceedings of the 24th International Conference on Logic Programming, ICLP 2008, held in Udine, Italy, in December 2008. The 35 revised full papers together with 2 invited talks, 2 invited tutorials, 11 papers of the co-located first Workshop on Answer Set Programming and Other Computing Paradigms (ASPOCP 2008), as well as 26 poster presentations and the abstracts of 11 doctoral consortium articles were carefully reviewed and selected from 177 initial submissions. The papers cover all issues of current research in logic programming - they are organized in topical sections on applications, algorithms, systems, and implementations, semantics and foundations, analysis and transformations, CHRs and extensions, implementations and systems, answer set programming and extensions, as well as constraints and optimizations.

This book celebratesthe 25th anniversaryof GULP—the Italian Associationfor LogicProgramming.Authored by Italian researchersat the leading edge of their ?elds, it presents an up-to-date survey of a broad collection of topics in logic programming, making it a useful reference for both researchers and students. During its 25-year existence, GULP has organised a wide range of national and international activities, including both conferences and summer schools. It has been especially active in supporting and encouraging young researchers, by providing scholarships for GULP events and awarding distinguished disser- tions. WeintheinternationallogicprogrammingcommunitylookuponGULPwith a combination of envy, admiration and gratitude. We are pleased to attend its conferences and summer schools, where we can learn about scienti?c advances, catch up with old friends and meet young students. It is an honour for me to acknowledge our appreciation to GULP for its outstanding contributions to our ?eld and to express our best wishes for its continuing prosperity in the future. March 2010 Robert Kowalski Imperial College London Preface On June 18, 1985, a group of pioneering researchers, including representatives from industry, national research labs, and academia, attended the constituent assembly of the Group of researchers and Users of Logic Programming (GULP) association. That was the starting point of a long adventure in science, that 1 we are still experiencing 25 years later. This volume celebrates this important event.
