Iran National OI Team Selection Contests
By Shayan, history, 3 years ago, In English

Hello everyone!

We are glad to invite you to participate in the Iran National OI Team Selection contests.

Every year in Iran, the Iranian National Olympiad in Informatics (INOI) committee conducts a summer camp to choose 8 top students to prepare them for next year's IOI and a spring camp to choose 4 out of those 8 to form the Iranian national team in IOI.

After the successful experience of holding the mirror of last year’s summer camp contest with few contestants, we are going to have the mirror of our national team selection on a larger scale. The level of these contests is around the IOI, and harder than the contests of the summer camp, and the point of holding the mirror of these contests is to help the IOI participants from other countries to prepare better for the IOI, and Persian younger students to have experience of these contests and prepare better for the future.

Now we want to invite the codeforces community to participate in the contests too.

Two contests will be held, each contest will have 3 problems with subtasks and duration of 5 hours, statements will be available in both English and Persian, you will have 7 days time, first 4 days are for participating and you can freely choose 5 hours to participate in the contest, after this 4 days tutorials will be released and you will have 3 days for upsolving problems, after that, the judge will be down.

The first contest time interval begins from May 29. 08:00 GMT, and the second contest time interval begins from June 5. 08:00 GMT. Contests will be held in inoi-judge, and you can see summer camp problems and other announcements there too, for more announcements and discussions you can join our telegram channel.

The whole ranking will be released after the contests, and the top 8 and the top 8 of Persian students under age 18 will be announced as honorary gold medalists, the dataset will be released for the public too, but if you wanted to use our problems in some contests or training camps, please contact us via iran.oi.judge@gmail.com and inform us.

PS:

The chosen national team this year is:

  1. Ali Safari (Amoo_Safar)
  2. Alireza Kaviani (alireza_kaviani)
  3. Ali Shahali (AliShahali1382)
  4. Alireza Keshavarz (Keshi)

In most of these last years we had rank around 3 to 5 in IOI, hope this team will end up with rank 1 or 2 and break our record. :)

I do not support the team, nor do I think Iran will have good results this year since the team has broken tradition and not provided the summer camp with dinner. However there is still time to change that and I hope the faculty and coaches take the necessary steps to ensure the success of this team.

    The English version has an incorrect third sample. The Persian statement has the correct answer.

I can't imagine how fast the computers in Iran are...

I passed the third problem in Day 1 with a solution with time complexity $$$O(nk^3)$$$ ( $$$n\leq 10^5,k\leq 30$$$ ).

And it's not the most amazing, I passed the second problem in Day 2 with a solution which time complexity is $$$O(n^3\log n)$$$ ( $$$n\leq 4\times 10^3$$$) !
