FUN is a series of conferences dedicated to the use, design, and analysis of algorithms and data structures, focusing on results that provide amusing, witty but nonetheless original and scientifically profound contributions to the area.

Fun is a notion that can be judged from different perspectives, and be defined in many different manners. The conference defines fun in a broad sense, including aspects such as elegance, simplicity, amusement, surprise, originality, etc.

The topics of interest include all aspects of algorithm design and analysis, and of computational complexity, under all types of models (sequential, parallel, distributed, streaming, online, etc.).

Submissions

Submissions should be made via the FUN 2026 submission server.

Submissions can have unlimited length, and authors are encouraged to submit complete papers, in A4 or letter format, 11pt, single column, with reasonable margins. The first ten pages of the submitted papers must include a self-contained description of the results, of their motivations and impact. Papers submitted for review should represent original, previously unpublished work. At the time the paper is submitted to the conference, and for the entire review period, the paper (or essentially the same paper) must not be under review by any other conference with published proceedings or by a scientific journal.

At least one author of each accepted paper is expected to physically attend the conference and present the paper.

The deadline for submission is January 13, 2026 (End of Day, Anywhere on Earth (AoE))

Conference proceedings will be published by LIPIcs, Schloss Dagstuhl – Leibniz Center for Informatics, Volume TBA. Authors of accepted papers will be asked to submit the final, camera-ready version of their paper in LIPIcs style not later than March 3, 2026. The page limit is 20 pages maximum, in total, i.e., including title, authors, affiliation, figures, bibliography, etc.

Selected papers will be invited to a special issue of Theoretical Computer Science.
