Hi! I'm running an online IOI camp for the fifth time. This edition is sponsored by Harbour.Space Institute of Technology. It's free for IOI participants and coaches. We also accept participants of regional olympiads like APIO, EGOI, BOI and CEOI 2026. Every day will be a 5-hour virtual contest, the problem analysis, and sometimes a lecture.

• Dates: from 29.07 until around 5.08 (6 training days, some day/s off)
• Contests: IOI 2016, 2 days of POI, 2 days of some regional olympiad like CEOI
• Registration: You need to register using this form https://harbour-space.typeform.com/to/Qu4pSHKF. I will later send you a Discord invite via e-mail. You should be a participant or a team leader for IOI 2026 or a regional (multi-national) olympiad in 2026.
• Lectures: The example lecture topics are those from Range Queries or Trees in Usaco Guide Platinum.
• Time: The Zoom analysis will start every day at 15:00 CEST. You can participate in a contest earlier that day, or a day before.

Thanks to the Harbour Space for sponsoring this online camp.
