Hey, guys, we have very important news for you!
The Grand Final of INST 2021 will be held as an ONLINE event due to the epidemiology situation. Travels are still dangerous, and we don't want our participants to be endangered. The tournament dates are still July 19-26, 2021.
All of the Grand Final problems will be published on our website soon. Also, the Team coordinator will contact you to confirm your participation in the Grand Final.


Finally, we are pleased to announce that the dates of the tournament have been determined: the Grand final of INST will be held from the 19th to 25th of July 2021!
As we all know, travels are challenging now. Therefore, in early June we announced whether the tournament will be held offline or online.
We are looking forward to seeing you all at the Grand final finally!


Dear friends, I regret to inform you that the Online round is canceled due to the lack of participating teams in the Online round. Most of the teams decided to participate only in the Grand final. From our side, we would like to hold an enthralling competition for both participants and jury members. That is why we have decided to cancel the Online round on the 6th of March so that not take your time and effort.
We are extremely sorry for the inconvenience and hope for your understanding.
At the end of March - beginning of April, we expect to announce the plausible dates of the Grand final and hope to see all of you there.


Less than two weeks left before the Online round! Here is the official program of the Online round, which will take place on March 6, 2021.


Hey, guys! The problems of the Online round are just here. So if you have participated in the Extramural round, then you have to solve only 2 more problems, and you're in! Hope to see you on the 6th of March!


We are happy to announce that the Online round of XI INST will be held on March 6, 2021. It’ll be a 1-day online tournament. Teams will prepare solutions of 4 out of 5 presented problems, which we will publish within a week.
