===================================================================== IFL 2025 37th Symposium on Implementation and Application of Functional Languages Montevideo, Uruguay October 1-3, 2025 https://www.fing.edu.uy/inco/congresos/ifl2025 ===================================================================== ### Scope The goal of the IFL symposia is to bring together researchers actively engaged in the implementation and application of functional and function-based programming languages. IFL 2025 will be a venue for researchers to present and discuss new ideas and concepts, work in progress, and publication-ripe results related to the implementation and application of functional languages and function-based programming. ### Topics of interest Topics of interest to IFL include, but are not limited to: - language concepts - type systems, type checking, type inferencing - compilation techniques - staged compilation - run-time function specialisation - run-time code generation - partial evaluation - (abstract) interpretation - meta-programming - generic programming - automatic program generation - array processing - concurrent/parallel programming - concurrent/parallel program execution - embedded systems - web applications - (embedded) domain specific languages - security - novel memory management techniques - run-time profiling performance measurements - debugging and tracing - virtual/abstract machine architectures - validation, verification of functional programs - tools and programming techniques ### Peer-review process Differently from previous editions of IFL, IFL 2025 solicits two kinds of submissions: * Regular papers (12 pages excluding references) * Draft papers for presentations ('weak' limit between 8 and 15 pages) Regular papers will undergo a rigorous review by the program committee, and will be evaluated according to their correctness, novelty, originality, relevance, significance, and clarity. Regular papers can be: accepted for publication in the formal proceedings, accepted for presentation at the symposium or rejected. Draft papers will be screened to make sure that they are within the scope of IFL, and will be accepted for presentation or rejected accordingly. We require that at least one of the authors present the work at IFL 2025. Authors of accepted presentations will be given the opportunity to incorporate the feedback from discussions at the symposium and will be invited to submit a revised full article for the formal post-proceedings after the symposium. The program committee will evaluate these submissions according to their correctness, novelty, originality, relevance, significance, and clarity, and will thereby determine whether the paper is accepted or rejected. ### Important dates Submission of regular papers: June 23, 2025 (extended) Regular papers notification: August 4, 2025 Submission of draft papers: August 4, 2025 Draft papers notification: August 11, 2025 Deadline for early registration: September 5, 2025 Submission of pre-proceedings version: September 8, 2025 IFL Symposium: October 1-3, 2025 Submission of papers for post-proceedings: December 15, 2025 Notification of acceptance: February 28, 2026 Camera-ready version: March 30, 2026 Deadlines are end of day Anywhere on Earth (UTC-12) (https://www.timeanddate.com/time/zones/aoe). ### Submission details All contributions must be written in English. Papers must use the ACM two columns conference format, which can be found at: http://www.acm.org/publications/proceedings-template Submit your paper here: https://easychair.org/conferences/?conf=ifl2025 Important note to authors about the new ACM open access publishing model ACM has introduced a new open access publishing model for the International Conference Proceedings Series (ICPS). Authors based at institutions that are not yet part of the ACM Open program and do not qualify for a waiver will be required to pay an article processing charge (APC) to publish their ICPS article in the ACM Digital Library. To determine whether or not an APC will be applicable to your article, please follow the detailed guidance here: https://www.acm.org/publications/icps/author-guidance. Further information may be found on the ACM website, as follows: - Full details of the new ICPS publishing model: https://www.acm.org/publications/icps/faq - Full details of the ACM Open program: https://www.acm.org/publications/openaccess - Please direct all questions about the new model to icps-info@acm.org. ### Peter Landin Prize The Peter Landin Prize is awarded to the best paper presented at the symposium every year. The honoured article is selected by the program committee based on the submissions received for the formal review process. The prize carries a cash award equivalent to 150 Euros. ### Organisation PC Chairs: Alberto Pardo, Universidad de la República, Montevideo, Uruguay Marcos Viera, Universidad de la República, Montevideo, Uruguay Publicity Chair: Mart Lubbers, Radboud University, The Netherlands Local Chairs: Alberto Pardo, Universidad de la República, Montevideo, Uruguay Marcos Viera, Universidad de la República, Montevideo, Uruguay ### Program committee: Matteo Cimini, University of Massachusetts Lowell Facundo Domínguez, Tweag João Paulo Fernandes, Universidade do Porto Jeremy Gibbons, Oxford University Jurriaan Hage, Heriot Watt University Jason Hemann, Seton Hall University Maja Hanne Kirkeby, Roskilde University Mart Lubbers, Radboud University Bruno C.
