The 17th Japanese Olympiad in Informatics Final Round Online Contest will be held on 11 Feb. (00:30 — 04:30 GMT).
The contest duration is 4 hours and there will be 5 problems, which is the same as the 17th JOI Final Round. Problem statements will be provided both in Japanese and English.
The registration page will be announced 30 minutes before the contest. I will update this blog post then.
You can see details in the contest information page.
UPD: The contest has postponed 30 minutes due to a technical issue. Sorry for inconvenience.
