The 39th International Conference on Logic Programming (ICLP 2023)
London, UK July 9-15, 2023
ICLP 2023 will be an in-person event in London, UK.
Since the first conference held in Marseille in 1982, ICLP has been the premier international event for presenting research in logic programming. Contributions are sought in all areas of logic programming, including but not restricted to:
- Theoretical Foundations.
- Language Design and Programming Methodologies.
- Program Analysis and Optimization.
- Implementation Methodologies.
- Related Paradigms, Integration, and Synergies.
- Applications of Logic Programming.
Tracks and Special Sessions
Besides the main track, ICLP 2023 will host additional tracks:
we invite submissions of papers on emerging and deployed applications of LP, describing all aspects of the development, deployment, and evaluation of logic programming systems to solve real-world problems, including interesting case studies and benchmarks, and discussing lessons learned.
we invite submissions to two thematic tracks, exploring specific roles and potential for logic programming; these thematic tracks are:
- Logic Programming and Machine Learning
- Logic Programming and Explainability, Ethics, and Trustworthiness
Recently Published Research Track:
this track provides a forum to discuss important results related to logic programming that appeared recently (from January 2021 onwards) in selective journals and conferences, but have not been previously presented at ICLP.
we invite submissions showcasing logic programming systems and implementations in a live setting. This track is not designed to be sales pitches, demonstrations are a way for the community to see the relevance, potential, and innovation of the tool and allow time for discussion with its creator.
Birds-of-a-Feather (BoF) sessions:
we invite proposals for sessions meant to provide an inclusive environment for colleagues with similar interests to meet for informal discussion. Proposers of BoF sessions should serve as discussion leaders only. BoFs are not intended to be presentations.
In addition, ICLP 2023 will host:
Doctoral Consortium and Mentoring Sessions:
the Doctoral Consortium (DC) on Logic Programming provides students and early career researchers with the opportunity to present and discuss their research directions, obtain feedback from both peers and experts in the field, and participate in mentoring sessions on how to prepare and succeed for a research career. We will have leaders in logic programming research from academia and industry to give invited talks on their research areas. The best paper from the DC will be given the opportunity to make a presentation in a session of the main ICLP conference.
Summer School on Logic Programming.
Logic Programming Contest.

(Deadlines expire at the end of the day, anywhere on earth.)
All submissions must be written in English.
We note that papers accepted at ICLP may appear either in
* Theory and Practice of Logic Programming Journal (TPLP), or
* Technical Communication Proceeding (TC) published by Electronic Proceedings in Theoretical Computer Science (EPTCS)
TPLP format is described at
EPTCS format is described at
All accepted papers will be presented during the conference. Authors of accepted papers will, by default, be automatically included in the list of ALP members, who will receive quarterly updates from the Logic Programming Newsletter at no cost.
For Main Track, Application Track, and Thematic Tracks:
All papers must describe original, previously unpublished research, and must not simultaneously be submitted for publication elsewhere. These restrictions do not apply to previously accepted workshop papers with a limited audience and/or without archival proceedings.
Regular papers (14 pages in TPLP format, including references)
The accepted regular papers will be published in TPLP. The program committee may recommend some regular papers to be published in Technical Communication Proceeding (TC). In this case, the papers will have to be reformatted into EPTCS format and not exceed 14 pages. Authors who submitted Regular papers that were accepted as TC may elect to convert their submissions into extended abstracts (2 or 3 pages in EPTCS format). This should allow authors to submit a long version elsewhere.
Short papers (7 pages in EPTCS format, including references).
The accepted short papers will be published in the Technical Communication Proceedings.
Recently Published Research Track
Extended abstract (2 or 3 pages in EPTCS format)
describing previously published research (from January 2021 onwards) in selective journals and conferences, but that have not been previously presented at ICLP. A title page should be appended to the submission with (i) details on the venue, where the original paper appeared, (ii) a link to the original paper, (iii) a paragraph describing why the authors believe this work warrants a presentation at ICLP. The extended abstracts will be published in the Technical Communication Proceedings.
System Demonstrations and BoF Proposals
Extended abstract (2 or 3 pages in EPTCS format).
System demonstrations should provide highlights of the novel features of the system, along with information about how to access it. BoF proposals should motivate the choice of the topic and its relevance to logic programming, describe the expected audience, identify discussion leaders and their expertise, and provide a brief description of the activities during the BoF session. We expect BoFs to be inclusive and involve active participation for attendees. Describe how your BoF will use inclusive practices and foster attendee involvement. The extended abstracts will be published in the Technical Communication Proceedings.
Submissions will be done via EasyChair.
