September 9-10, 2025 - Rende, Italy

https://lopstr.github.io/2025/

Important dates: - Abstract submission: May 9, 2025 (AoE) - Paper submission: May 16, 2025 (AoE) - Author notification: June 27, 2025 (AoE) - Camera-ready: July 17, 2025 (AoE) - Symposium: September 9-10, 2025

OVERVIEW

The aim of the LOPSTR series is to stimulate and promote internationalresearch and collaboration on logic-based program development. LOPSTRis open to contributions to logic-based program development in anyprogramming language paradigm. LOPSTR has a reputation for being a lively, friendly forum for presenting and discussing work in progress.

LOPSTR 2025 will be held at the University of Calabria, Rende, Italy. It will be co-located with ICLP 2025 and PPDP 2025. At least one of the authors of an accepted paper is expected to attend the conference and present the paper. Information about venue and travel will be available on the ICLP 2025 website.

Topics of interest include 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, butnot limited to:

 - synthesis - transformation - specialization - inversion - composition - optimisation - specification - analysis and verification - testing and certification - program and model manipulation - AI methods for program development - verification and testing of AI-based systems - transformational techniques in software engineering - logic-based methods for security  - logic-based methods for cyber-physical and distributed systems - applications, tools, and industrial practice

Survey papers that present some aspects of the above topics from a newperspective and papers that describe experience with industrialapplications and case studies are also welcome.

PAPER SUBMISSION

Submissions can be made in two categories:

 - Regular Papers (15 pages max.) - Short Papers (8 pages max.)

References will NOT count towards the page limit. Additional pages maybe used for appendices not intended for publication. Reviewers are notrequired to read the appendices, and thus papers should be intelligiblewithout them. All submissions must be written in English.

Submissions must not substantially overlap with papers/tools that havebeen published or that are simultaneously submitted to a journal,conference, or workshop with refereed proceedings.

Submissions of Regular Papers must describe original work. Work that already appeared in unpublished or informally published workshopproceedings may be submitted (please contact the PC Chairs in case ofquestions). 

Submissions of Short Papers may include presentations of exciting ifnot fully polished research or tool demonstrations that are ofacademic and industrial interest. Tool demonstrations should describethe relevant system, usability, and implementation aspects of a tool.

All accepted papers will be included in the conference proceedings andpublished by Springer as a Lecture Notes in Computer Science (LNCS)volume.

After the symposium, a selection of a few best papers will be invitedfor submission to rapid publication in the Journal of Theory andPractice of Logic Programming (TPLP). Authors of selected papers willbe invited to revise and/or extend their submissions to be consideredfor publication. The papers submitted to TPLP will be subject to thejournal's standard reviewing process.

SUBMISSION GUIDELINES

Authors should submit an electronic copy of the paper (written inEnglish) in PDF, formatted in the Lecture Notes in Computer Sciencestyle. Each submission must include on its first page the paper title;authors and their affiliations; contact author's email; abstract; andthree to four keywords which will be used to assist the PC inselecting appropriate reviewers for the paper. Authors should consultSpringer's authors' instructions on the author's page, and use theirproceedings templates, either for LaTeX (available also in Overleaf)or for Word, for the preparation of their papers. Springer encouragesauthors to include their ORCIDs in their papers. In addition, uponacceptance, the corresponding author of each paper, acting on behalfof all of the authors of that paper, must complete and sign aConsent-to-Publish form. The corresponding author signing thecopyright form should match the corresponding author marked on thepaper. Once the files have been sent to Springer, changes relating tothe authorship of the papers cannot be made.

Page numbers (and, if possible, line numbers) should appear on themanuscript to help the reviewers in writing their report. So, forLaTeX, we recommend that authors use:

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

Papers should be submitted via EasyChair:https://easychair.org/conferences/?conf=lopstr2025
