Spain Olympiad in Informatics 2023 Online Mirror
By FelixMP, history, 21 month(s) ago, In English

Hello!

I invite you to participate in the 27th Spain's Olympiad in Informatics' Online Mirror. This is the second year we are doing the mirror after last year's good reception. The two contests will start on 2023 March 25 14:30 UTC and 2023 March 26 8:00 UTC and will last 4 hours each.

Contest facts:

  • Two 5-tasks contests with OI scoring (subtasks).
  • Statements in English and Spanish.
  • Problems are not ordered by difficulty.
  • Problem selection and preparation directed by FelixMP. The full list of authors will be published after the contest.
  • The problems will cover a wide range of difficulties, and the subtasks make it possible to progress in all problems, so it should be an interesting contest for participants of all skill levels. For reference, see the problems from previous years on Codeforces Gym.
  • The allowed languages will be C++, Java and Python.
  • It is possible to participate on only one day, and the two different times make it convenient to participate in at least one of the days from almost anywhere in the world.

In order to participate in the contest, you must register using this form. The contest will be held in a CMS platform and you will receive your credentials and instructions for participating in the email you provided on the form. The deadline for registering is 23 March.

Good luck and enjoy the problems!

    It will be available in the following weeks. Probably problems will be posted in CF gym, just like 2021&2022 edition. You can discuss the problems here if you want something for now.

    Participants in the mirror should receive in the following week a link to an upsolving CMS server which will be available for a limited time. After that, the problems will be uploaded to CF Gym at some point.
