What is OCPC?

OCPC is a training camp for university teams preparing for ICPC and similar competitions. Both winter editions use the same seven contests, so choose one edition.

Online teams can start each contest within 24 hours of its onsite start and get the full five-hour run. Solution discussions follow the onsite schedule, with recordings available afterwards.

See the Hong Kong schedule or Osijek schedule. Please keep the problems private until their release is authorized.
