Hi everyone!
Supported by
The OCPC (Osijek Competitive Programming Camp), an award-winning camp for university students to prepare for ICPC and other coding competitions, is back again this winter, on January 24 — February 1, 2026!
The camp is organized by adamant and -is-this-fft- on the premises of the University of Osijek in Osijek, Croatia.
The camp is inspired by various competitive programming camps that we attended during our active years in ICPC, and is aimed to help college students prepare for ICPC regional contests and finals. The camp will consist of 7 ICPC-style contests and 2 days off.
Details
The participation fee for both online and onsite participants is 198€ per team.
Similar to previous camp editions, the fee does not include regular meals, travel or accommodation.
We support and empathize with those affected by the ongoing war in Ukraine, therefore we offer a free participation for affected individuals and teams affiliated with Ukrainian institutions.
Additionally, we would like to offer the following discounts:
- Early bird discount: We offer a reduced participation fee of 147€ per team if you register before December 17, 2025.
- Hardship discount: We offer fee reduction to 99€ per team, on request, if you feel that default fee makes it a financial burden for you.
We do not require any proof or documentation when using the hardship option, and trust your self-assessment. Nevertheless, we ask you to be mindful when using it, as we still have to rely on participation fees as the baseline for running the camp.
The expected starting time for the contests is 10am CET. For remote participants, it is still a preferred starting time, but we will make accommodations for virtual participation at a later time, when necessary.
Most of our contests are originally developed for the camp. A small number of contests may be based on previous contests that have not been released to the general public. If you have seen some problems of a contest before, you can't participate on that day. We will privately contact participants who might be affected.
After the camp, we will have a silence period during which camp materials will not be released to the public. We ask participants not to discuss the problems in public unless they obtained an explicit permission from contest authors.
If you would like to get a feel of the contests, you can find links to some of the previously published camp contests here.
If you have any questions about the camp, please feel free to send us an email, or join our Discord server!
Participants
If you are interested in participating, please fill the form here.

We ask you to register before January 17, 2026 if you want to participate remotely and before January 10, 2026 if you want to participate in Osijek. If you require a visa, please register as soon as possible, as it might take a few weeks to receive (depending on your location).
If your university or organization has a lively ICPC community that may be interested in attending the camp, and you have some contacts of people in charge (e.g. coaches) we would highly appreciate if you could share some details in a direct message to me. Thanks!
