Call for Papers

SOFSEM is an annual winter conference devoted to the theory and practice of computer science. The conference traditionally focuses on the latest results and developments of fundamental research in computer science (informatics), inspired by the algorithmic challenges of our time. SOFSEM has a long tradition as a high-quality research conference, and a venue where researchers from academia and industry in all stages of their career can share their insights.

The 52nd SOFSEM will be held February 2–5, 2027 as a physical event in Ioannina, Greece. An on-site pre-conference PhD school on Graph Algorithms and Geometry will be held on Monday, February 1, 2027. The proceedings will be published in the series Lecture Notes in Computer Science (LNCS) by Springer. Additionally, authors of selected papers presented at the conference will be invited to submit extended versions to a special issue of the Discrete Mathematics & Theoretical Computer Science.

Submission Guidelines and Proceedings

SOFSEM 2027 proceedings will be published in the subseries ARCoSS (Advanced Research in Computing and Software Science) of the Lecture Notes in Computer Science (LNCS) series of Springer. Contributors are invited to submit an extended abstract of up to 12 pages in Springer LNCS format (www.springer.com/lncs), including title and abstract, but excluding references. Proofs omitted due to space restrictions must be placed in an appendix, to be read by program committee members at their discretion. 

Papers must be submitted electronically through EasyChair. The submission server is: https://easychair.org/conferences/?conf=sofsem2027

No prior publication or simultaneous submission to other conferences or journals are allowed (except preprint repositories such as arXiv or workshops without formal published proceedings). Submissions are not anonymous.

Authors will be required to submit their accepted papers to the arXiv repository at the same time as submitting their camera-ready versions, in order to provide immediate and unrestricted open access to their papers. The self-archived arXiv papers should consist of (essentially) the LNCS proceedings version plus an optional clearly marked appendix.

At least one author of each accepted paper is required to present the paper at the conference. Also, an individual registration is required for each accepted paper.

Topics of Interest

The program committee encourages submission of original research papers in all areas of foundations of computer science and artificial intelligence, including but not limited to the following:

  • algorithm engineering,
  • algorithms and data structures,
  • automata, languages, rewriting systems,
  • combinatorial optimization,
  • combinatorics on words,
  • computability, decidability, models of computation,
  • computational complexity,
  • computational geometry,
  • cryptography and security,

Awards

SOFSEM 2027 will offer awards for the best paper and the best student paper. The awards will be decided by the program committee. The committee can decide to split the awards over multiple papers, or not to offer an award. Papers eligible for the best student paper can have non-student co-authors, but the main work in a paper that is a candidate for the best student paper award must be done by co-authors that were students at the time of submission, and the award can be received only by such co-authors. It must be indicated at the time of submission whether a paper is a candidate for this award.

Venue

The conference will be held in the "Karolos Papoulias Conference Center", which is located in the University Campus. The campus is located at a 6 km distance from the city centre and access is possible by urban bus that runs every 10 mins from the city centre.
