Hello Codeforces, especially girls!
The second Europian Girls Olympiad of Informatics just finished. The competition was hosted by Turkey in Antalya. It was the first year this competition was held onsite. EGOI is somehow a girls' version of IOI because countries like Singapore and Peru participate in it too. 45 countries participated in EGOI 2022, while the number of countries participating in IOI is ~90.
I was part of the scientific committee of the competition. I found a great team around me.
From left to right: Fatma Basak Aydemir (Turkey, SC), Nils (Sweden, Problem Setter), Hakan (Turkey, SC), Cheng (China, Problem Setter), I (Iran, SC), Stanislaw (Poland, Problem Setter), Vlad (Romania, SC), Petr (Switzerland, Problem Setter). Tolga Can didn't attend on-site but he was the head scientific committee. Also, Fatih Damirci (head of the Turkey informatics olympiad) was the organizer of the event. He helped us (the Scientific Committee) in many ways.
The Turkish host did everything so that it couldn’t be possible to improve it. I’m wondering if some other country could bet them in the future. We stayed for a week in a 5-star hotel near the beach, two excursion days, and a boat trip. Here you can see what happened in EGOI 2022.
This year, we had more countries and also, stronger participants. Then we prepared a significant harder contest. To give an approximation, the problems were ranging between Div.2 D and Div.2 F.
The results are here. Duru from Turkey took the official first place and made the host very happy.
You can find solutions here (it’s possible that the subtasks don’t match). I'll add solutions for other problems soon. The problems will be soon online for practice.
Thanks to arsijo the problems can be virtually upsolved here:

Fixed.
no
I changed the link: https://ubilo.tubitak.gov.tr/egoi2022/results
No
Unfortunately, the website is down.
Will it be fixed anytime soon ?
Problems are on CF gym. Look above.
oh sorry I haven't noticed. Thanks
Why isn't Georgia in the official list?
GA voted to have Georgia as an official country from the next year if I remember correctly.
Weobe ORZ
And congrats to keta_tsimakuridze for winning EGOI!!
Is there any plan to publish contest in the Gym (like last year)?
Yes. Please wait.
I think it has been quite a long wait now. Any updates?
Please wait.
It's ready. We need someone to check if everything is working, a tester. Please message me.
Will the official grader for the interactive problems be released? Thanks!
I asked for it.
Where could I find the general solution of the problem Data Centres? The link given has the solution for only first 3 subtasks...
Subtask 3 in the pdf is the full solution for the problem on the real contest.
... competition was held onsite... a girls' version of IOIThe only photo in the blog perfectly shows us the amazing atmosphere of this truly unique girls-only programming event!
well they technically didn't say that the organizers are girls too
Yes, there was one girl from Estonia.
And only European countries being official perfectly shows that it’s a version of IOI(where I stands for international, not European).

Congratulations!
The EGOI problems can be virtually upsolved here:
Day1: https://egoi2022-1.eolymp.io/
Day2: https://egoi2022-2.eolymp.io/
There are some issues with the subtasks of Day 1 Question 2 (Lego Wall).
Subtask 3 should not be dependent on subtask 1 and 2 as subtask 3 requires both $$$h$$$ and $$$w$$$ to be smaller than 100 while subtask 1 and 2 have separate constraints on $$$w$$$ and $$$h$$$.
Sorry about that. Fixed.
Hi! Thank you (and the setters) for this great problem set, I really liked it.
I discover something in the problem "Cheat": The judge isn't doing any of the operations to shuffle the vector/rotate the card.
In the "BuildPattern" function, the first segment that I add to the vector always is (0,1)-(1,1), and in the "GetCardNumber" function, the first segment (P[0]) is always P[0].first = (0,0) and P[0].second = (1,1), I checked it with an assert.
My code got AC until subtask 5 (It should get AC only in subtask 3 and 4, since I don't consider rotation).
Fixed.
The statements seem to be not available.
Use PDF version.
