Hi everyone!
... And a happy May day!
We are very happy to announce that OCPC (formerly, the Osijek Competitive Programming Camp) is back this Summer, on June 21-29, 2025! While the dates are pretty tight, they appear to be the ones that are most suitable (among all the summer internships, exams, other coding events, etc) for the majority of people who filled the dates questionnaire.
This time, the camp is hosted by the Faculty of Mathematics and Computer Science of the University of Bucharest in Bucharest, Romania and is brought to you by the organizing team of adamant, -is-this-fft- and livlivi.
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.
Mirror camps
Before going into further details, we would also like to announce that we expect the following mirror sites this Summer:
- India: OCPC with the collaboration of GoForGold and ICPC India will have an onsite mirror for top teams from India, so if you are one of the world finalist or got top rank in this year Asia West Finals and have chances left for world finals then you can join Indian mirror which will be scheduled during the second half of July.
- Indonesia: We will also organize a mirror site on the premises of the Bina Nusantara University (BINUS) in Jakarta for people based in the APAC region. This mirror is planned to be held in the late August, shortly before ICPC World Finals.
The mirror sites use the same consest sets, but typically have a different organizing team (for example, this winter, a mirror in Singapore, APAC was organized by errorgorn). As the mirror sites will happen after the European (and online) camp edition, they will be properly announced later on. Mirror sites are primarily intended for onsite participation, so if you are geographically located in the corresponding region (or are willing to go there for the camp), we encourage you to wait for the corresponding announcement.
If you want to participate remotely or in Europe, please register for the Bucharest edition of the camp (the one announced here).
Details
The participation fee for both online and onsite participants is 201€ 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.
The expected starting time for the contests is 10am CEST. 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 June 14 if you want to participate remotely and before June 7 if you want to participate in Bucharest. If you require a visa, please register as soon as possible, as it might take a few weeks to receive (depending on your location).
Also, 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!
