What is this?
OCPC is a camp to prepare students for ICPC and similar programming competitions. It is aimed at the highest level of competition, i.e. teams who wish to show strong results in ICPC regionals and participate seriously in ICPC World Finals. Each edition consists of a series of ICPC-style contests (5 hours, 9–12 problems each) for 3-person teams, with analysis sessions and days off in between.
The camp was founded in 2023 and has since run editions in Osijek and other host cities. Browse all past editions, contest mirrors and standings in the archive.

What people say about us?
“OCPC has helped us grow as a team, with an almost endless supply of fun ICPC contests, sometimes with interesting twists! And after contests you can always hang out with other cool CPers :)”
- • ICPC 2025 World Finals Silver Medalist
“I really like the camp and try to participate in it whenever I get a team together.”
“Because our university doesn't have a top team, we don't get invited to any other camps, so it is great to participate at least in this camp. I would say it is organized quite well and the quality of contests is high. Participating in the camp is also useful because that way I have the motivation to train competetive programming. I would definitely recommend this camp to others because it will help with competetive programming.”
- • 9th place in NWERC 2024 (Bronze)
- • 13th place in EUC 2025
- • ICPC 2025 World Finalist
“Really great experience, enjoyable problems and wide range of techniques to learn. For me, ~2200 codeforces enjoyer, there was a lot new or unfamiliar topics, or some interesting applications”
- • 12th place in EUC 2025 (Bronze)
- • ICPC 2025 World Finalist
“For me, OCPC is a time of the year I always highly await. The high quality selection of contests have always proven to be a great and fun challenge to bond over and learn more and new tricks and topics.”
“The organizers also made sure to always provide the best conditions for us the contestants (e.g. snacks outside the contest halls during the competition days) and organized very efficiently icebreaker and teambuilding events in the break days. Overall, I highly recommend participation to this camp for everyone regardless of their skill as they have a lot to gain from participating.”

Who can participate?
Participation is open to anyone, but the camp is primarily aimed at ICPC-eligible teams representing universities. You compete in teams of up to three; the participation fee is charged per team rather than per person, so a fuller team pays less per participant.
Participation fee
The participation fee for both online and onsite participants is 198€ per team (the same for all sites). As in previous editions, it does not include regular meals, travel or accommodation.
Discounts
- Early bird discount: Reduced fee of 147€ per team if you register at least a month before your edition starts — by 8 July 2026 for Hong Kong, or 12 August 2026 for Iași.
- Hardship discount: Fee reduction to 48€ per team, on request, if the default fee creates a financial burden for you. We do not require any proof or documentation, and trust your self-assessment. Nevertheless, we ask you to be mindful when using this option, as we rely on participation fees to run the camp.
- Ukraine support: We support and empathize with those affected by the ongoing war in Ukraine, and offer free participation for affected individuals and teams affiliated with Ukrainian institutions.
Individual sites may add their own arrangements — see each camp page.
Fees are charged in euros, per team. Payments are processed by OCPC LLC, the operator of ocpc.camp — after you register we send your team an invoice payable by card or bank transfer. Cancellations before your camp starts are refunded in full; no refunds are given after the camp starts. See the Terms & Refund Policy.
