JOI Open Contest 2016
This is an IOI-like open competition for students at schools for secondary education. The main purpose of this contest is to give an opportunity to Japanese delegations and candidates of delegations for training and practice. But the contest itself is open to everybody. Everybody is welcome to attend JOI Open Contest 2016!
The duration of the contest is 5 hours. The same contests are held twice (Round 1 and Round 2). Contestants can participate in one of Round 1 or Round 2 according to their time zone. After Round 2 finishes, we will open the judging server for one day. Interested contestants can improve and resubmit their solutions by themselves.
Registration will be open before each contest. A link to the registration page will appear on this page about 30 minutes before the beginning of each contest. Contestants can register on the contest site by themselves from the right before the beginning of each contest until the end of it.
No prizes will be given to the contestants.
