The 26th International Symposium on Principles and Practice of Declarative Programming, PPDP 2024

Co-located with FM 2024, held 10-11 September 2024 at the Politecnico di Milano, Italy.



The PPDP 2024 symposium brings together researchers from the declarative programming communities, including those working in the functional, logic, answer-set, and constraint handling programming paradigms. The goal is to stimulate research in the use of logical formalisms and methods for analyzing, performing, specifying, and reasoning about computations, including mechanisms for concurrency, security, static analysis, and verification.

Submissions are invited on all topics related to declarative programming, from principles to practice, from foundations to applications. Topics of interest include, but are not limited to:

The PC chairs will be happy to advise on the appropriateness of a topic.

PPDP will take place 9-11 September 2024 at the Politecnico di Milano, Italy, co-located with the 34th Int’l Symp. on Logic-Based Program Synthesis and Transformation (LOPSTR 2024) within the umbrella of FM 2024

Submission Categories

Submissions can be made in three categories:

Submissions of Research Papers must present original research which is unpublished and not submitted elsewhere. They must not exceed 12 pages ACM style 2-column (including figures, but excluding bibliography). Work that already appeared in unpublished or informally published workshop proceedings may be submitted (please contact the PC chair in case of questions). Research papers will be judged on originality, significance, correctness, clarity, and readability.

Submission of System Descriptions must describe a working system whose description has not been published or submitted elsewhere. They must not exceed 10 pages and should contain a link to a working system. System Descriptions must be marked as such at the time of submission and will be judged on originality, significance, usefulness, clarity, and readability.

Submissions of Experience Reports are meant to help create a body of published, refereed, citable evidence where declarative programming such as functional, logic, answer-set, constraint programming, etc., is used in practice. They must not exceed 5 pages including references. Experience Reports must be marked as such at the time of submission and need not report original research results. They will be judged on significance, usefulness, clarity, and readability.

Possible topics for an Experience Report include, but are not limited to:

Supplementary material may be provided via a link to an extended version of the submission (recommended), or in a clearly marked appendix beyond the above-mentioned page limits. Reviewers are not required to study extended versions or any material beyond the respective page limit. Material beyond the page limit will not be included in the final published version.


The PPDP 2024 proceedings, ISBN 979-8-4007-0969-2, will published in the ACM Digital Library within the ACM International Conference Proceedings Series.

Important note to authors about the new ACM open access publishing model

ACM has introduced a new open access publishing model for the International Conference Proceedings Series (ICPS). Authors based at institutions that are not yet part of the ACM Open program and do not qualify for a waiver will be required to pay an article processing charge (APC) to publish their ICPS article in the ACM Digital Library. To determine whether or not an APC will be applicable to your article, please follow the detailed guidance here.

Further information may be found on the ACM website, as follows:

Format of a submission

For each paper category, you must use the most recent version of the Current ACM Master Template, at the time of writing being 2.01. You must use the LaTeX sigconf proceedings template, as the conference organizers are unable to process final submissions in other formats. In case of problems with the templates, contact ACM’s TeX support team at Aptara.

Authors should note ACM’s statement on author’s rights which apply to final papers. Submitted papers should meet the requirements of ACM’s plagiarism policy.

Requirements for publication

At least one author of each accepted submission will be expected to attend and present the work at the conference. The PC chair may retract a paper that is not presented. The PC chair may also retract a paper if complaints about the paper’s correctness are raised which cannot be resolved by the final paper deadline.

Review process

The reviewing is single-blind, with a two-days rebuttal phase.
