                PPDP 2018: Deadline Extension
======================================================================
                 20th International Symposium on
        Principles and Practice of Declarative Programming

         Frankfurt am Main, Germany, 3-5 September 2018

        http://ppdp-lopstr-18.cs.uni-frankfurt.de/ppdp18.html

            (co-located with LOPSTR 2018 and WFLP 2018)
             http://ppdp-lopstr-18.cs.uni-frankfurt.de
======================================================================



Invited Talks
=============

-   Philippa Gardner, Imperial College: Testing and Verification for
    JavaScript (joint with LOPSTR)
-   Jorge Navas, SRI International: Constrained Horn Clauses for
    Verification (joint with LOPSTR)
-   Chung-Chieh Shan, University of Indiana: Calculating Distributions

Scope
=====

The PPDP 2018 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

-   Language Design: domain-specific languages; interoperability;
    concurrency, parallelism, and distribution; modules; probabilistic
    languages; reactive languages; database languages; knowledge
    representation languages; languages with objects; language
    extensions for tabulation; metaprogramming.

-   Implementations: abstract machines; interpreters; compilation;
    compile-time and run-time optimization; memory management.

-   Foundations: types; logical frameworks; monads and effects;
    semantics.

-   Analysis and Transformation: partial evaluation; abstract
    interpretation; control flow; data flow; information flow;
    termination analysis; resource analysis; type inference and type
    checking; verification; validation; debugging; testing.

-   Tools and Applications: programming and proof environments;
    verification tools; case studies in proof assistants or interactive
    theorem provers; certification; novel applications of declarative
    programming inside and outside of CS; declarative programming
    pearls; practical experience reports and industrial application;
    education.

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

PPDP will be co-located with the 28th Int'l Symp. on Logic-Based Program
Synthesis and Transformation (LOPSTR 2018).

Submission Categories
=====================

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:

insights gained from real-world projects using declarative programming
comparison of declarative programming with conventional programming in
the context of an industrial project or a university curriculum
curricular issues encountered when using declarative programming in
education real-world constraints that created special challenges for an
implementation of a declarative language or for declarative programming
in general novel use of declarative programming in the classroom
programming pearl that illustrates a nifty new data structure or
programming technique.

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.

Format of a submission
======================

For each paper category, you must use the most recent version of the
"Current ACM Master Template" which is available at
<https://www.acm.org/publications/proceedings-template>. 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](mailto:acmtexsupport at aptaracorp.com).

Authors should note [ACM's statement on author's
rights](http://authors.acm.org/) which apply to final papers. Submitted
papers should meet the requirements of [ACM's plagiarism
policy](http://www.acm.org/publications/policies/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.
