IIOT — Open Contests 2021/22 — ROUND 1 Announcement
By Kaey, history, 2 years ago, In English

The first round of the IIOT (International Informatics Olympiads in Teams) is starting tomorrow, November 15th 2021! The open contest will be 3 hours USACO-style, starting from 17:30 CET, and ending 27 hours after that. In the meanwhile, you can enjoy our teaser below and try to guess the next nine 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/
  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/ 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!

I am an official contestant from Egypt

Are we allowed to copy a prewritten code? and are we allowed to see the standings during the contest?

    For the first question, you have to ask your local organizers. For the second one, the answer is yes and you can find it here.

Because this was a team contest, my team (errorgorn, oolimry, dantoh, tqbfjotld) decided to use google docs*, the best IDE for collaborative programming. We recommend using google docs for team contests as you are able to collaborate in real time. Furthermore, google docs contains many useful features such as

  • embedding pictures in code
  • custom syntax highlighting
  • custom font sizes
  • comic sans
  • and many more

We would share the google docs that we used to FC this contest but the contest is still running, I will share it once the mirror is over.
