Revision en4, by joisino, 2017-03-24 07:16:15

Hello Codeforces!

Japanese Olympiad in Informatics Spring Camp 2017 will be held from Mar. 19 to Mar. 25.

There will be four online mirror contests during the camp.

The contest duration is 5 hours and there are 3 to 4 problems in each day. Problem statements will be provided both in Japanese and English this year.

There might be unusual tasks such as output-only tasks, optimization tasks, reactive tasks and communication tasks, just like International Olympiad in Informatics (IOI).

Details are available in contest information.

Good luck and have fun!

UPD1:

We will use CMS (customized version) on our server to hold the contests. The registration URL will be announced just before the first contest.

Providing English statements is our first trial for this year, so there aren't past English problems. If you try past problems with Google Translate, you can get them from here.

UPD2:

Registration is available now.

UPD3:

The contests are over. The judge is open now. You can submit your codes in the contest page.
