POPL 2024
Wed 17 - Fri 19 January 2024 London, United Kingdom

PADL is a well-established forum for researchers and practitioners to present original work emphasizing novel applications and implementation techniques for all forms of declarative programming, including functional and logic programming, databases and constraint programming, and theorem proving.

PADL’24 will take place during 15-16 January 2024 as a physical (in-person) event. For each accepted paper at least one author is required to register for the conference and present the paper in person.


Unlike previous years, the registration for PADL’24 is handled separately from POPL. Please note that at least one author of each accepted paper must register specifically to PADL.

Call for Papers

PADL is a well-established forum for researchers and practitioners to present original work emphasizing novel applications and implementation techniques for all forms of declarative programming, including functional and logic programming, databases and constraint programming, and theorem proving.

Topics of interest include, but are not limited to:

  • Innovative applications of declarative languages
  • Declarative domain-specific languages and applications
  • Practical applications of theoretical results
  • New language developments and their impact on applications
  • Declarative languages and software engineering
  • Evaluation of implementation techniques on practical applications
  • Practical experiences and industrial applications
  • Novel uses of declarative languages in the classroom
  • Practical extensions such as constraint-based, probabilistic, and reactive languages

PADL 2024 especially welcomes new ideas and approaches related to applications, design and implementation of declarative languages going beyond the scope of the past PADL symposia, for example, advanced database languages and contract languages, as well as verification and theorem proving methods that rely on declarative languages.


PADL 2024 welcomes three kinds of submission:

  • Technical papers (max. 15 pages): Technical papers must describe original, previously unpublished research results.

  • Application papers (max. 8 pages): Application papers are a mechanism to present important practical applications of declarative languages that occur in industry or in areas of research other than Computer Science. Application papers are expected to describe complex and/or real-world applications that rely on an innovative use of declarative languages. Application descriptions, engineering solutions and real-world experiences (both positive and negative) are solicited.

  • Extended abstracts (max. 3 pages): Describing new ideas, a new perspective on already published work, or work-in-progress that is not yet ready for a full publication. Extended abstracts will be posted on the symposium website but will not be published in the formal proceedings.

All page limits exclude references. Submissions must be written in English and formatted according to the standard Springer LNCS style, see https://www.springer.com/gp/computer-science/lncs/conference-proceedings-guidelines

The review process of PADL 2024 is double-anonymous. In your submission, please, omit your names and institutions; refer to your prior work in the third person, just as you refer to prior work by others; do not include acknowledgements that might identify you.

Additional material intended for reviewers but not for publication in the final version - for example, details of proofs - may be placed in a clearly marked appendix that is not included in the page limit. Reviewers are at liberty to ignore appendices and papers must be understandable without them.

Page numbers (and, if possible, line numbers) should appear on the manuscript to help the reviewers in writing their reports. So, for LaTeX, we recommend that authors use:


The conference proceedings of PADL 2024 will be published by Springer-Verlag in the Lecture Notes in Computer Science series. Work that already appeared in unpublished or informally published workshops proceedings may be submitted but the authors should notify the program chairs where it has previously appeared.

Papers should be submitted electronically at https://padl2024.hotcrp.com

Distinguished Papers

The authors of a small number of distinguished papers will be invited to submit a longer version for journal publication after the symposium. For papers related to logic programming, that will be in the journal Theory and Practice of Logic Programming (TPLP), and for papers related to functional programming, in Journal of Functional Programming (JFP). The extended journal submissions should be substantially (roughly 30%) extended: explanations for which there was no space, illuminating examples and proofs, additional definitions and theorems, further experimental results, implementational details and feedback from practical/engineering use, extended discussion of related work, and so on. These submissions will then be subject to the usual peer review process by the journal, although with the aim of a swifter review process by reusing original reviews from PADL.
