Hello, Codeforces! 🤗

We are happy to invite you to participate in COMPFEST 14 Preliminary Online Mirror (Unrated, ICPC Rules, Teams Preferred) on . COMPFEST is a national ICPC-style contest for university students in Indonesia.

The problems are written and prepared by Pyqe, steven.novaryo, Nyse, muhammadhasan01, gansixeneh, nandonathaniel, FerdiHS, TakeMe, and NeoZap.

We would also like to thank:

  • KAN for helping to host the mirror round;
  • rama_pang (rama_pang, yz_, Berted), pengzoo (DishonoredRighteous, golikovnik), bukanYohandi, bry_rp, Drew_, and david.alexander01 for testing the contest and providing us very useful feedback;
  • Universitas Indonesia, all the local committees, administrators, and managers of the whole COMPFEST event;
  • prabowo for existing;
  • fushar for the Judgels platform used in the official contest; and finally
  • MikeMirzayanov for the amazing Codeforces and Polygon platform!
  • Extra thanks for Pyqe for the dedication and effort 💪 in COMPFEST 14, as without him, the contest would not exist.

The contest will last for 5 hours and consist of 13 problems. While it is preferred to participate in a team, individual participation is also allowed. The problems themselves are expected to be easier than ICPC Regional contest.

COMPFEST itself is an annual event hosted by Universitas Indonesia. It is the largest student-run IT event in Indonesia and competitive programming contest is one of the competitions hosted.

We hope you will enjoy and have fun in the contest. Good luck!!

Indian participants won't be able to participate as we have our common preliminary round for all regionals at the same time.

    This contest is ICPC rules. Each problem is worth 1 point, each rejected runs have a 20-minute penalty.

    Here is an example contest with the same format.
