Hi. I'm organizing an online IOI-preparation camp in collaboration with Huawei. Every day will be a 5-hour virtual contest, then my problem analysis, and sometimes a lecture. There will be at least 4 contests and 2 lectures.

We will do some old IOI contests (2013?) from the IOI archive, CEOI (2015-2016?), or maybe JOI/JOISC — to be decided this weekend. I don't want to do recent years like 2021 because most participants already covered it. The example lecture topics are those from Range Queries or Trees in Usaco Guide Platinum.

The camp is free for IOI 2022 participants. For everybody else, the video recordings will be posted on Youtube after the camp. By participating you get the live experience (Discord, asking questions, competing with others, leaderboards).

Dates: 25.07-2.08 (updated)
Time of every analysis/lecture: 14:00 UTC / 16:00 CEST
Price: free for IOI participants, 40 USD for everybody else
Platform: Discord & Codeforces & uj.oz (?)

How to register?

Big thanks to Huawei UK R&D for sponsoring this camp.

EDIT: I'm now aware of CEOI collision. There's nothing I can do about it :(

Schedule:
25.07 — CEOI 2016 day 1
26.07 — CEOI 2022 day 1 + lecture
27.07 — CEOI 2016 day 2
28.07 — CEOI 2022 day 2
29.07 — lecture + homework
weekend off
1.08 — CEOI 2017 day 1
2.08 — CEOI 2017 day 2

Participants voted to cover CEOI instead of IOI to avoid problems that they already know.

Sorry about announcing this so late. It was difficult to choose dates, and I wasn't sure about my availability.

Anyway, I encourage you to let your country team know about this camp. It should be a great final practice before the coming finals!

Instead, you can show me proof of donating at least 40 USD to recent IOI-related crowdfunding events (e.g. PavelKunyavskiy for IOI archive; or sending Greek & Tunisian teams to IOI), and CF "badges of support".

I just want to mention that Greek & Tunisian IOI team crowdfundings are much more useful, and ask everyone to prefer them.

... and CF "badges of support" ...

So, to participate, you must have one of the badges?

    There won’t be. It’s not how learning works.
