-------------------------------------------------------------------------- CALL FOR PAPERS -------------------------------------------------------------------------- 39th Workshop on (Constraint and Functional) Logic Programming (WLP 2025) https://www.imn.htwk-leipzig.de/WLP2025/ -------------------------------------------------------------------------- Workshop at Declare 2025 (September 24-26, 2025 in Evora, Portugal) https://declare.di.uevora.pt/ co-located with: 16th Workshop on AI-based Management, Optimization and Configuration (MOC 2025) 2nd Workshop on Intelligent Digitalization (IntDig 2025) -------------------------------------------------------------------------- The Workshops on (Constraint) Logic Programming are the annual meeting of the German Society of Logic Programming [Gesellschaft für Logische Programmierung e.V. (GLP)](http://www-ps.informatik.uni-kiel.de/GLP/) The workshops provide provide a forum for exchanging ideas on declarative logic programming, constraint logic programming, non-monotonic reasoning, knowledge representation, and facilitates interactions between research in theoretical foundations and the design, implementation and application of (constraint) logic-based systems. Declarative approaches - especially in combination with other AI technologies and disruptive non-AI technologies - have an increasing relevance for digitalization projects in many sectors. Contributions are welcome on all aspects of logic programming (LP), constraint programming (CP), functional logic programming (LP), and other fields of artificial intelligence, including, but not limited to the following areas: Logic programming Constraint programming Functional logic programming Deductive databases, data mining Extensions of declarative languages, objects Multi-paradigm declarative programming Foundations, semantics, nonmonotonic reasoning, dynamics Parallelism, concurrency Program analysis, abstract interpretation Program transformation, partial evaluation, meta-programming Specification, verification, declarative debugging Knowledge representation, machine learning Interaction of declarative programming with other formalisms/ AI technologies Implementation of declarative languages Advanced programming environments and tools Software engineering in the context of declarative programming Applications & project descriptions, e.g. in the fields planning, scheduling, configuration, computational law Lessons learned by teaching in the addressed fields Submissions: Authors should submit an electronic copy of the full paper in PDF. Papers should be submitted via the EasyChair conference management system (https://easychair.org/conferences/?conf=wlp2025). Authors are invited to submit extended abstract (no longer than 12 pages, excluding references) system description (no longer than 6 pages, excluding references). Papers must describe original work, be written and presented in English, and must not substantially overlap with papers that have been published or that are simultaneously submitted to a journal, conference, or workshop with refereed proceedings. However, work that already appeared in unpublished or informally published workshops proceedings may be submitted, too. Workshop languages are German and English. Important dates: Submission deadline: July 18th, 2025 (extended) Notification of acceptance: August , 2025 Workshop: September 24th, 2025 Workshop Chair: Sibylle Schwarz (HTWK Leipzig, Germany) Program Committee: Slim Abdennadher (German University Cairo, Egypt) Salvador Abreu (University of Évora, Portugal) Stefan Brass (University of Halle, Germany) Ulrich Geske (University of Potsdam, Germany) Michael Hanus (University of Kiel, Germany) Petra Hofstedt (BTU Cottbus-Senftenberg, Germany) Ulrich John (International University of Applied Sciences, Germany) Dietmar Seipel (University of Wuerzburg, Germany) Mario Wenzel (University of Halle, Germany)
