IIOT — Open Contests 2024/25 — ROUND 1 Announcement
By Kaey, 3 days ago, In English

The first round of the IIOT (International Informatics Olympiads in Teams) is starting on Monday November 11th 2024! The open contest will be 3 hours USACO-style, starting from 17:00 CET, and ending 27 hours after that. In the meanwhile, you can enjoy our teaser below and try to guess the next problems from the hints :)

This contest, of a lower difficulty level than the IOI, is intended for teams of 4 contestants from the same high school (check this post for further details). However, everyone is welcome to participate to the open contests!

If you want to participate, you must:

  1. Visit the contest website: https://mirror.squadre.olinfo.it/ for the standard division or https://mirror-esordienti.squadre.olinfo.it/ for the debutant division.
  2. Click the link "register", fill out the form and then click on the register button and then "back to login"
  3. You can now log in with the same username and password you used to sign up
  4. If the login is successful you will be ready to participate, just wait for the contest to start! (and maybe save the page in your bookmarks, so that you can quickly get back to it when the contest begins)
  5. When the contest starts, you will see a red button. Click it when you want to start your 3 hour time window!
  6. The ranking for each contest will be available at https://mirror.squadre.olinfo.it/ranking/ or https://mirror-esordienti.squadre.olinfo.it/ranking/ after the start of each contest
  7. The tasks will also be available for training in https://training.olinfo.it/#/tasks/ few days after the contests
  8. Good luck and have fun!

We hope that you will join us or encourage your students to do so!

      Oh okay, I thought the editorial won't be published as it's not a regular CF round. Anyways, thanks for the hints.
