39th Workshop on (Constraint and Functional) Logic Programming (WLP 2025)

September 24, 2025 in Évora, Portugal

Workshop at Declare 2025 (September 24-26, 2025 in Évora, Portugal)
and co-located with

Call for Papers WLP 2025

General

The Workshops on (Constraint) Logic Programming are the annual meeting of the German Society of Logic Programming Gesellschaft für Logische Programmierung e.V. (GLP) and brings together researchers interested in logic programming, constraint programming, answer set programming, and related areas like databases and artificial intelligence (not only from Germany).

The workshops provide a forum for exchanging ideas on declarative programming, especially logic, constraint logic and functional logic programming, nonmonotonic reasoning and knowledge representation, and facilitate interactions between research in theoretical foundations and in the design and implementation of logic-based programming systems.

The technical program of the workshop will include invited talks, presentations of refereed papers, and system demonstrations.

Topics

Contributions are welcome on all theoretical, experimental, and application aspects of logic programming (LP) and constraint programming (CP), including, but not limited to the following areas (the order does not reflect any priorities):

Logic Programming and Extensions

  • logic programming
  • constraint and constraint logic programming
  • functional logic programming
  • multi-paradigm declarative programming
  • implementation and extensions of declarative languages
  • foundations, semantics, specification, verification
  • dynamics, parallelism, concurrency

Knowledge Representation and Nonmonotonic Reasoning

  • deductive databases, data mining
  • knowledge representation, non-monotonic reasoning
  • rule-based systems
  • abductive and inductive logic programming
  • answer-set programming
  • semantics and proof-theoretical investigations

Application of Logic Programming

  • applications & project descriptions, e.g. in the fields planning, scheduling, configuration, computational law
  • logic programming in production, management, environment, education, medicine, internet, etc.
  • cp/lp for semantic web applications and reasoning on the semantic web
  • data modelling for the web, semistructured data, and web query languages
  • lessons learned by teaching in the addressed fields

Implementation of Systems

  • program analysis, abstract interpretation
  • program transformation, partial evaluation, meta-programming
  • interaction of declarative programming with other formalisms/ ai technologies
  • software techniques for declarative programming, programming environments and tools
  • system descriptions, comparisons, evaluations
  • benchmarks
  • implementation techniques
  • software techniques and programming support (e.g., types, modularity, design patterns, debugging, testing, systematic program development).

Submission Details

Authors are invited to submit papers in the following categories:

  • extended abstract (no longer than 12 pages including figures and references) or
  • system description (no longer than 6 pages, excluding references)

via the EasyChair submission website for WLP 2025.

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.

Proceedings (to be confirmed)

All accepted papers will be published as a technical report and made available electronically at the workshop. As for previous events, it is planned to publish selected papers as post-conference proceedings.
