Call for Papers

The 13th International Symposium on Algorithms and Complexity is planned to take place from 13 June to 16 June 2023 in Larnaca, Cyprus. It will follow the recent, very successful editions of CIAC 2021 online, CIAC 2019 in Rome, Italy, CIAC 2017 in Athens, Greece, CIAC 2015 in Paris, France and CIAC 2013 in Barcelona, Spain.



Authors are invited to submit papers presenting original and unpublished research on algorithms and complexity. Typical areas include:

  1. algorithm design and analysis
  2. sequential, parallel and distributed algorithms 
  3. data structures 
  4. computational and structural complexity
  5. lower bounds and limitations of algorithms 
  6. randomized and approximation algorithms
  7. parameterized algorithms and parameterized complexity classes
  8. smoothed analysis of algorithms
  9. alternatives to the worst-case analysis of algorithms (e.g., algorithms with predictions)
  10. on-line computation and competitive analysis
  11. streaming algorithms
  12. quantum algorithms and complexity
  13. algorithms in algebra, geometry, number theory and combinatorics
  14. computational geometry 
  15. algorithmic game theory and mechanism design
  16. algorithmic economics (including auctions and contests)
  17. computational learning theory
  18. computational biology and bioinformatics
  19. algorithmic issues in communication networks
  20. algorithms for discrete optimization (including convex optimization)
  21. algorithm engineering


Authors are invited to submit an extended abstract or full paper with at most 15 pages, excluding the title page and the references. The title page consists of the title of the paper, author information and the abstract. The first section of the paper should start on the next page.

The usage of the LNCS style file is mandatory. No changes to font size, page geometry, etc. are permitted. Late submissions and submissions not in the correct format will not be considered. Submissions will be through EasyChair (

The paper should contain a succinct statement of the issues and their motivation a summary of the results, a brief explanation of their significance and a comparison to related work, accessible to non-specialists. Proofs omitted due to space constraints must be put into an appendix, to be read by the PC members at their discretion.

Simultaneous submission to other conferences with published proceedings or to journals is not allowed.

At least one author of each accepted paper will have to register for the conference. For authors who cannot present their paper in person for a significant reason, possibility for remote presentation may be offered.
