This book constitutes the refereed proceedings of the Second International Workshop on Practical Aspects of Declarative Languages, PADL 2000, held in Boston, MA, USA in January 2000.The 21 revised full papers presented were carefully reviewed and selected from a total of 36 submissions. The papers are organized in topical sections on functional programming, functional-logic programming, logic programming, innovative applications, constraint programming and constraint solving, and systems applications.

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.

This volume contains the proceedings of the 24th International Conference on Logic Programming (ICLP 2008). The conference took place in Udine, Italy during December 9-13, 2008. The conference focuses on the foundations, dev- opments, and applications in the area of logic programming. The ICLP series of conferences is aimed at providing a technical forum for presenting and d- seminating innovative research results in the ?eld of logic programming. The conference features technical presentations, tutorials, invited speakers, and a number of co-located events, including: - The First Workshop on Answer Set Programming and Other Computing Paradigms (ASPOCP 2008) - The Annual Meeting of the ISO/IEC JTC1/SC22/WG17 working group on the standardization of Prolog - The Third International Workshop on Applications of Logic Programming to (Semantic) Web and Web Services (ALPSWS'08) - The18thWorkshoponLogic-basedMethodsin ProgrammingEnvironments (WLPE 2008) - The 8th Colloquium on Implementation of Constraint Logic Programming Systems (CICLOPS 2008) - The 15th RCRA Workshop on Experimental Evaluation of Algorithms for Solving Problems with Combinatorial Explosion ICLP 2008 also featured two special events. The ?rst was the 4th ICLP Doctoral Student Consortium, an event speci?cally organized to encourage p- ticipation and interaction between doctoralstudents working in the area of logic programming. The second event was a special session celebrating 20 years of Stable Model Semantics.
