WLP 2026 Call for Papers

40th Workshop on
(Constraint and Functional) Logic Programming (WLP 2026)
https://www.imn.htwk-leipzig.de/WLP2026/

Workshop at INFORMATIK 2026 (https://informatik2026.gi.de)
September 23, 2026 in Dresden, Deutschland
--------------------------------------------------------------------------

The Workshops on (Constraint) Logic Programming are the annual meeting of the German Society of Logic Programming [Gesellschaft
fuer Logische Programmierung e.V. (GLP)](https://www.glp-ev.de/)

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 or functional) 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 and
in LaTex format using LNI style
(https://gi.de/service/publikationen/lni) 
 via the ConfTool conference management system (https://www.conftool.org/informatik2026/index.php?page=newPaper&form_contributiontypeID=27&newpaper=true). Before submitting, you have to register (https://www.conftool.org/informatik2026/)

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 or German, 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.
