LOPSTR 2021
31st International Symposium on
Logic-based Program Synthesis and Transformation
September 7-9, 2021 - Tallinn, Estonia
Co-located with PPDP 2021

Overview

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 at the Tallinn, Estonia. Previous symposia were held in Bologna (as a virtual meeting), Porto, Frankfurt am Main, Namur, Edinburgh, Siena, Canterbury, Madrid, Leuven, Odense, Hagenberg, Coimbra, Valencia, Lyngby, Venice, London, Verona, Uppsala, Madrid, Paphos, London, Venice, Manchester, Leuven, Stockholm, Arnhem, Pisa, Louvain-la-Neuve and Manchester (you might have a look at the contents of past LOPSTR symposia at DBLP).

LOPSTR 2021 will be co-located with PPDP 2021. Information about venue and travel is available on the joint PPDP/LOPSTR conference website.

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
  • optimisation
  • 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 Work that already appeared in unpublished or informally published workshop proceedings may be submitted (please contact the PC chairs in case of questions).

Submission Guidelines

Authors should submit an electronic copy of the paper (written in English) in PDF, formatted in the Lecture Notes in Computer Science 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. So, for LaTeX, we recommend that authors use:

\pagestyle{plain}
\usepackage{lineno}
\linenumbers

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 the Easychair submission website for LOPSTR 2021.

Proceedings

The formal post-conference proceedings will be published by Springer in the Lecture Notes in Computer Science series as in previous years (the complete list of previous LOPSTR proceedings is available here). 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' instructions and use their proceedings templates, either for LaTeX (available also in Overleaf) or for Word, for the preparation of their papers. Springer encourages authors to include their ORCIDs in their papers. In addition, the corresponding author of each paper, acting on behalf of all of the authors of that paper, must complete and sign a Consent-to-Publish form. The corresponding author signing the copyright form should match the corresponding author marked on the paper. Once the files have been sent to Springer, changes relating to the authorship of the papers cannot be made.

Best Paper Awards and Prizes

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).
