Hello Codeforces!

We are going to hold some online OI-style contests, the tasks are the selected tasks, chosen from the older Iran national team selection contests.

The level of these contests is around the IOI, maybe a bit simpler, and the main reason of them is to help Iranian students to prepare better for the summer camp contests, which will be held around 3 weeks from now and the national medalists will be chosen there.

And also we did translate tasks to English, so that if anyone from anywhere wanted to prepare for the IOI or other competitions could use it too.

We will have 1 contest per week, and you can freely choose 5 hours to participate in the contest, after each contest the top performers will be announced.

You can participate in contests on the inoi-judge website, the first contest time period starts from Aug 10. 08:00 GMT, There is no need of registration from now, whenever a contest starts you can go and participate in it.

Also, you can see tasks of this year’s contests in the problemset, just keep in mind that you should first login to see the tasks.

And also you can join our telegram channel if you want, further content and posts will be there.

The INOI Team Selection 2021 Online Mirror Competition has ended, now the second-day contest’s tasks are on the judge for upsolving, and statements, editorials, and testcases of tasks released here.

We want to apologize if there were any issues in the contests and thank all the people who gave us feedback.

We had an interesting talk with Zixiang Zhou (duality) who has won 2 gold medals and a silver medal in IOI at age 16 and also got 600 points in our competition. we asked some questions about himself, how he practices and his strategy in the contests. We believe it can be beneficial for everyone. You can see this talk in our telegram channel.

Also, soon we will have online mirrors of our summer camp contests and our Regional ICPC, and some other stuff.

Hope this will be helpful.

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 [email protected] 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. :)
