IIOT 18/19 - Finals

The final round of the IIOT 2018/19 (International Informatics Olympiad in Teams) will be held on Friday, February 8th, 2019.

Even if you missed the first rounds, your teams can still join in!

The contest is intended for teams of 4 high school contestants, it consists of 8 problems in English at a lower difficulty level than IOI, and lasts for 3 hours USACO-style: teams can choose a time window starting from 11:00 in the CEST/CET time zone, and ending 24 hours after that. For detailed information on how to participate see this post: https://codeforces.com/blog/entry/62572.


Everyone is welcome to participate, especially if you are considering to join officially the IIOT in the future!
