Drużynowa IOI

For the sixth time, the International Informatics Olympiad in Teams is taking place and will be mirrored into online rounds. These contests have a lower difficulty level than those of the IOI, and are intended for teams are intended for teams of 4 contestants from the same high school. However, everyone is welcome to participate to the mirror contests, especially if you are considering to join officially the IIOT in the future!

More specifically, we allow:

  • several teams from the same school (also in the official contest)
  • teams participating only in some contests (also in the official contest)
  • smaller teams (also in the official contest) and larger teams
  • teams of students from different schools and non-students
  • changes in team members between contests

The mirror contests timing will be USACO-like: it will be open for 27 hours but you will be able to compete for up to 3 hours (you can decide when to "start" your time window, after the login). Participation will be available upon registration (re-registration needed for each contest). The problem statements will be available in English only, and the languages officially supported are C, C++, Pascal and Python 3. Every contest will consist of 9 problems (see https://squadre.olinfo.it and https://iio.team for further information).

Note: you can decide when to start your 3 hour time window, but remember that the contest will end 27 hours after the start of the official contest regardless of your time window!
