WFLP 2017

25th International Workshop on Functional and Logic Programming

31st Workshop on (Constraint) Logic Programming

September 19-22, 2017

collocated with INAP 2017 and part of Declare 2017 - Conference on Declarative Programming


WFLP 2017 is the combination of two workshops of a successful series of annual workshops on declarative programming. The international workshops on functional and logic programming aim at bringing together researchers interested in functional programming, logic programming, as well as their integration. The workshops on (constraint) logic programming serve as the scientific forum of the annual meeting of the Society of Logic Programming (GLP e.V.) and bring together researchers interested in logic programming, constraint programming, and related areas like databases, artificial intelligence, and operations research.

In this year both workshops will be jointly organized and collocated with the 21st International Conference on Applications of Declarative Programming and Knowledge Management (INAP 2017) and the Summer School on Advanced Concepts for Databases and Logic Programming under the umbrella of the Declare 2017 - Conference on Declarative Programming in order to promote the cross-fertilizing exchange of ideas and experiences among researchers and students from the different communities interested in the foundations, applications, and combinations of high-level, declarative programming languages and related areas. The technical program of the workshop will include invited talks, presentations of refereed papers and demo presentations.

The topics of interest include (but are not limited to):

  • Functional programming
  • Logic programming
  • Constraint 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 (e.g., agents, XML, Java)
  • Implementation of declarative languages
  • Advanced programming environments and tools
  • Software technique for declarative programming
  • Applications

The primary focus is on new and original research results but submissions describing innovative products, prototypes under development, application systems, or interesting experiments (e.g., benchmarks) are also encouraged.

Important dates

Submission of abstracts: July 05, 2017
Submission of papers: July 08, 2017
Notification of acceptance: July 24, 2017
Camera-ready papers: August 04, 2017
Conference/Workshop: September 19-22, 2017

Submission Guidelines

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. Work that already appeared in unpublished or informally published workshop proceedings may be submitted (please contact the PC chair in case of questions).

Papers can be submitted in the following categories:

  • technical papers
  • system descriptions

Technical papers should consist of up to 15 pages, system descriptions should be no longer than 8 pages (including references). Formatting should follow the LNCS guidelines which are available here, along with formatting templates and style files.

Authors should submit an electronic copy of the full paper in PDF. Papers should be submitted via the submission website for WFLP 2017.

Submitted papers will be judged on the basis of significance, relevance, correctness, originality, and clarity. They should include a clear identification of what has been accomplished and why it is significant.


All accepted papers will be published in a technical report. As for previous events, selected papers will be published as a volume in the Springer LNAI series.

Proceedings of previous events appeared as Springer LNCS volumes 8439 (WFLP 2013), 6816 (WFLP 2011), 6559 (WFLP 2010), 5979 (WFLP 2009), 5437 (WLP 2007), and 3392 (WLP 2004).
