18th International Symposium on Functional and Logic Programming, May 26-28, 2026, Tsukuba, Japan

https://functional-logic.org/events/flops/2026/

FLOPS aims to bring together practitioners, researchers and implementers of declarative programming, to discuss mutually interesting results and common problems: theoretical advances, their implementations in language systems and tools, and applications of these systems in practice. The scope includes all aspects of the design, semantics, theory, applications, implementations, and teaching of declarative programming. FLOPS specifically aims to promote cross-fertilization between theory and practice and among different styles of declarative programming.

Previous FLOPS meetings were held at Fuji Susono (1995), Shonan Village (1996), Kyoto (1998), Tsukuba (1999), Tokyo (2001), Aizu (2002), Nara (2004), Fuji Susono (2006), Ise (2008), Sendai (2010), Kobe (2012), Kanazawa (2014), Kochi (2016), Nagoya (2018), Akita (2020, online), Kyoto (2022, online), and Kumamoto (2024).

Scope

FLOPS solicits original papers in all areas of declarative programming:

• functional, logic, functional-logic programming, rewriting systems, formal methods and model checking, program transformations and program refinements;

• developing programs with the help of theorem provers or SAT/SMT solvers, verifying properties of programs using declarative programming techniques, or statistical methods including generative AI (*);

• foundations, language design, implementation issues (compilation techniques, memory management, run-time systems, etc.), applications and case studies.

FLOPS promotes cross-fertilization among different styles of declarative programming. Therefore, research papers must be written to be understandable by a wide audience of declarative programmers and researchers. In particular, each submission should explain its contributions in both general and technical terms, clearly identifying what has been accomplished, explaining why it is significant for its area, and comparing it with previous work. Submission of system descriptions and declarative pearls are especially encouraged.

(*) Note that FLOPS is a Programming Languages conference. Submissions should be accessible to a Programming Languages audience. The Program Committee has been selected from that audience, and it may be unable to gauge the quality of your submission if that requires specialized competencies in statistical methods and/or AI. Special attention should also be paid to the reproducibility of the results from public sources.
