Call for problems


We are seeking you problem ideas for NCPC 2026!

You can submit problems in two ways:

  1. By e-mailing a problem idea to the Competitive Programming Association of Iceland keppnisforritun+ncpccfp@gmail.com no later than Sunday, June 28 2026 (UTC+00).
  2. By submitting a problem to NWERC and marking it as a simultaneous submission to NCPC. Further instructions are available at https://2026.nwerc.eu/cfp.

If you go for option 1, the following instructions apply. A problem proposal should consist of a draft of a problem statement (simple text file is fine), as well as a short description of the intended solution. Test data and a sample solution is appreciated, but not required. If you submit anything more than a simple text file, please follow the Kattis problem package format. It should be possible to implement the intended solution with at most a few hundred lines of code and it should not take more than a couple of seconds to run. See https://nordic.icpc.io/archive for previous years’ problems.

Note that if you submit a problem and it is selected, then you can not participate in NCPC.

Communication regarding the problem selection and later problem preparation is handled through a mailing list, which you will be added to if you propose a problem.

If you would like to be part of the jury involved in selecting/voting on which problems are used, please mention that in your email and briefly mention who you are. You can apply to do this even if you do not submit a problem
