Call For Papers

31st International Symposium on Logic-Based Program Synthesis and Transformation

Tallinn (Estonia) and Virtual
September 7-9, 2021
(co-located with PPDP 2021)

* Important update:
* The conference will be held as a hybrid (blended) meeting, both in-person and virtual.


The aim of the LOPSTR series is to stimulate and promote international research and collaboration on logic-based program development. LOPSTR is open to contributions in logic-based program development in any language paradigm. LOPSTR has a reputation for being a lively, friendly forum for presenting and discussing work in progress. Formal proceedings are produced only after the symposium so that authors can incorporate this feedback in the published papers.

The 31st International Symposium on Logic-based Program Synthesis and Transformation (LOPSTR 2021) will be held as a hybrid (blended) meeting, both in-person (at the Teachers' House in Tallinn, Estonia) and virtual.
Previous symposia were held in Bologna (as a virtual meeting), Porto, Frankfurt am Main, Namur, Edinburgh, Siena, Canterbury, Madrid, Leuven, Odense, Hagenberg, Coimbra, Valencia, Kongens Lyngby, Venice, London, Verona, Uppsala, Madrid, Paphos, London, Venice, Manchester, Leuven, Stockholm, Arnhem, Pisa, Louvain-la-Neuve, and Manchester.
LOPSTR 2021 will be co-located with PPDP 2021 (International Symposium on Principles and Practice of Declarative Programming).

Topics of interest cover all aspects of logic-based program development, all stages of the software life cycle, and issues of both programming-in-the-small and programming-in-the-large, including, but not limited to:

- synthesis
- transformation
- specialization
- composition
- optimization
- inversion
- specification
- analysis and verification
- testing and certification
- program and model manipulation
- machine learning for program development
- verification and testing of machine learning systems
- transformational techniques in SE
- applications and tools

Both full papers and extended abstracts describing foundations and applications in these areas are welcome. Survey papers that present some aspects of the above topics from a new perspective and papers that describe experience with industrial applications are also welcome.

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 chairs in case of questions).

* Important Dates *

Abstract submission (optional): May 1, 2021 (AoE)
Paper/Extended abstract submission: June 25, 2021
Notification: July 16, 2021
Camera-ready (for electronic pre-proceedings): August 20, 2021
Symposium: September 7-9, 2021
Revised paper submission: November 1, 2021 (AoE)
Notification: December 1, 2021
Final version (for post-proceedings): January 16, 2022

* Submission Guidelines *

Authors should submit an electronic copy of the paper (written in English) in PDF, formatted in LNCS style. Each submission must include on its first page the paper title; authors and their affiliations; contact author's email; abstract; and three to four keywords which will be used to assist the PC in selecting appropriate reviewers for the paper. Page numbers (and, if possible, line numbers) should appear on the manuscript to help the reviewers in writing their report. Full papers cannot exceed 15 pages excluding references. Extended abstracts cannot exceed 8 pages excluding references. Additional pages may be used for appendices not intended for publication. Reviewers are not required to read the appendices, and thus papers should be intelligible without them. Papers should be submitted via EasyChair:

* Proceedings *

The formal post-conference proceedings will be published by Springer in the Lecture Notes in Computer Science series as in previous years. Full papers can be directly accepted for publication in the formal proceedings, or accepted only for presentation at the symposium and inclusion in informal proceedings. After the symposium, all authors of extended abstracts and full papers accepted only for presentation will be invited to revise and/or extend their submissions. Then, after another round of reviewing, these revised papers may also be published in the formal proceedings. Authors should consult Springer's authors' guidelines and use their proceedings templates for the preparation of their papers. Springer encourages authors to include their ORCIDs in their papers.

* Best paper awards *

Thanks to Springer's sponsorship, two awards (including a 500 EUR prize each) will be given at LOPSTR 2021. The program committee will select the winning papers based on relevance, originality and technical quality but may also take authorship into account (e.g. a student paper).
