Final standings and open contest

November 25, 2021

It's our pleasure to announce that all appeals have been resolved and the NWERC 2021 standings have been finalized without any changes. Congratulations again to the NWERC 2021 Champions, Sidney's Cat Tree from the University of Cambridge, as well as all our medalists.

All the contest materials have been published on our website, including the problem set, solution slides, test data and judges' solutions. Also worth mentioning is that this Saturday, November 27th, at 9:00 GMT+0 we will be hosting an open version of NWERC 2021 on Open Kattis.

It's been our pleasure to organize NWERC for the last two years. The ICPC flag is already on its way to TU Delft in the Netherlands, who will be organizing NWERC 2022 and NWERC 2023. We wish them the best of luck with the organization, and hope to see you in Delft next year!

If you are a coach, or contestant that has competed in NWERC for the last time, and are interested in receiving the NWERC 2022 Call for Problems, please send an email to titled "Call for Problems signup".

Last but not least we would like to thank our sponsors, Huawei, Jetbrains, AWS Educate and Reykjavík University for making this event possible! You can find more information about them on our sponsors page.

Friday update

Tomorrow is the day of the practice session. A link to the livestream will be posted on the website tomorrow morning.

A few notes about the format this weekend:

  • The judges have published a document with advice, hints, and general information about the contests this weekend. Contestants are asked to read it in full as it contains important new information, in particular about the inclusion of interactive problems this year.
  • Public standings for the contests can be found at
  • Due to the online nature of the contest this year, we have decided not to hold a simultaneous open contest, and to keep the problemset private until after the contest.
  • Instead, a separate public contest will be held on Open Kattis on Saturday, November 27th from 10:00 - 15:00 GMT+1.

Contest format update

September 19, 2021

After much deliberation we - the NWERC 2021 organizers - have concluded that is still not feasible for us to host a safe onsite NWERC this November. To keep the contest safe and fair we will be repeating last year's online format on November 20-21, incorporating your suggestions to make it even better. Please see this year's rules for more details.
