The rules for this contest are given by the ICPC regional contest rules, with the following clarifications and additions.

In order to keep the contest a safe and fair event for everyone we have decided to employ the fully online format from NWERC 2020. The following temporary rules are intended to accommodate for this change, and take precedence over the official ICPC regional rules where there are contradictions.


Contestants are allowed to participate from any location of their choice. Team members do not have to gather at the same location.


Contestants are allowed to use their own computers and electronic devices.

Internet access

Contestants are allowed to use the internet during the contest, with two restrictions:

  • Contestants are not allowed to publish or post any information on the internet during the contest.
  • Contestants must only read information that was published before the start of the contest.

Examples uses of the internet that are NOT allowed during the contest:

  • Posting information about the problems or sending anyone the problem statements.
  • Asking questions on Stack Overflow or any other forums.
  • Reading discussion threads that may include information about the Winter Contest 2022 problems.

Existing code

Contestants are allowed to use preexisting code found on their computers or on the internet, provided that it does not violate any other rules about internet access (in particular, the code must have been published before the start of the contest).


Contestants are allowed to communicate with their own team members during the contest, and are encouraged to set up a private voice or video conference for their team during the contest. Contestants are also allowed to communicate with organizers and the jury through the "Clarifications" interface in the judging system, where any and all issues during the contest or questions about the problem statements should be directed. Contestants are not allowed to communicate with anyone else (including but not limited to their coach, friends, contestants from other teams, or anyone else on the internet or in person) during the contest.


There are no restrictions on software use during the contest. Contestants are allowed to use any operating system, IDE or editor they like, and configure that software in any way they like before the contest. In particular, contestants may configure their editor to use a code template of their choice, provided it does not violate any other rules about use of existing code.
