Indonezyjska OI - 3-5.10.2022

We are pleased to invite you to Indonesian NOI Open Contest 2022 — an online mirror contest for Indonesian National Olympiad in Informatics 2022. This national olympiad is one of the selection tests for our students to represent Indonesia in the International Olympiad in Informatics (IOI).

The competition is similar to IOI: 2 contest days (+ 1 trial session), each consisting of 3 IOI-style (partial, subtasks) problems to be solved in 5 hours. The schedule is as follows:

Each contest will be held as a virtual contest: each contestant can choose any 5-hour window within the time range for each contest day.

The task statements will be available in both Indonesian and English. The allowed programming language is only C++. Public scoreboard will be revealed after the second contest day.

All three contests are now open for registration on TLX, our Indonesian online judge. For more detailed information and rules, visit
