The PPDP 2019 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.
The 21th International Symposium on Principles and Practice of Declarative Programming will take place 7–9 October 2019 in Porto, Portugal. The symposium will be collocated with Symposium on Formal Methods, FM'19 and a part of the FM Week.
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 chair will be happy to advise on the appropriateness of a topic.
PPDP 2019 will be held in Porto, Protugal. Previous symposia were held at
Frankfurt am Main (Germany),
Montréal (Canada), and
They are indexed by the DBLP Computer Science Bibliography.
Submissions can be made in three categories: regular Research Papers, System Descriptions, and Experience Reports.
Submissions of Research Papers must present original research which is unpublished and not submitted elsewhere.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 Work that already appeared in unpublished or informally published workshop proceedings may be submitted (please contact the PC chair in case of questions).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 in a clearly marked appendix beyond the above-mentioned page limits. Reviewers are not required to study any material beyond the respective page limit.
For each paper category, you must use the most recent version of the "Current ACM Master Template" which is available at ACM webpage. The most recent version at the time of writing is 1.48. 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 applies to final papers. Submitted papers should meet the requirements of ACM's plagiarism policy.
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.
The reviewing is single-blind.
PPDP 2019 is organised in cooperation with ACM and SIGPLAN.
