  • 2022 recordings — CEOI 2016, CEOI 2017, CEOI 2022, optimization problems, segment tree nodes
  • 2023 recordings — POI 2019, POI 2022, CEOI 2018, graphs

Hi! For a fourth time, I'm organizing an online IOI camp sponsored by Huawei. It's free for IOI participants and coaches. UPDATE: we will accept participants of regional olympiads too (from this year, so e.g. BOI/EGOI/CEOI/APIO 2025)! Every day will be a 5-hour virtual contest, the problem analysis, and sometimes a lecture.

  • Dates: 17-23.07 (6 training days; Sunday off)
  • Contests: IOI 2015, POI 2024 and something else from POI/BOI/CEOI
  • [EDIT] Registration: You need to register using this form https://www.smartsurvey.co.uk/s/SWYTGK/. I will later send you a Discord invite via e-mail. You should be a participant or a team leader for IOI 2025.
  • Lectures: The example lecture topics are those from Range Queries or Trees in Usaco Guide Platinum.
  • Time: The analysis will start every day at 16:00 CEST. You can participate in a contest earlier that day, or a day before. The analysis on Saturday 19.09 will be shifted because of the CF round.

Feel free to make suggestions in the comments.

    This is only for IOI participants, sorry. But you can watch the recordings from previous years. (Ofc. first try to solve the problems on your own!)

The registration is open. You need to fill the form https://www.smartsurvey.co.uk/s/SWYTGK/

We've decided to accept more people this year: participants of IOI and also participants of regional olympiads (CEOI, BOI, APIO, EGOI, etc.). Though keep in mind that the camp is aimed towards students around the bronze medal level at IOI.

    In the form there are options to choose that I started my bachelor at 2022, and participated in ICPC stages, does it mean that students can also join(as preparation for icpc wf)?

      No, sorry. Huawei uses this form for various events, including icpc too. For this camp, you need to compete in an international olympiad.

    Let's say that EJOI is not enough but Balkan OI is. It's ok that you went last year, unless you also graduated high school that year and you're now a college student.

    I'm afraid it's too late to shift the dates. And it's very hard to avoid all the collisions. You can check out the contests and recordings from previous camps.

I've just sent the Discord invites via e-mail. If you haven't received one, check your spam folder or refill the form. We start tomorrow with IOI 2015 day 1.

The camp registration ends in 24 hours: tomorrow at noon.
