If you know any other countries' delegations, let me know in the comments. Thanks!
Why duplicated blogs ??
similar blog opened here
furthmore, my name is Hasan Jaddouh not Hasan Jaddou , as written in my passport and my codeforces profile ,please fix it
So far I've seen about 0 commitment from the other post — no table, no adding data from comments etc. Let's see how this goes. Also, why have you asked to change your name only here? :)
Alex7 Last visit: 14 hours ago , maybe you should wait until he enter codeforces then judge him.
also I told my friend to change my name in facebook :)
Well, of course, but to start with a table would have been a great start. Anyway, I believe Alex7 and professorbrill should talk to each other/fight each other/throw a dice/etc. and decide on one thread to leave, if they both going to maintain the page, but the duplicates of this type of threads aren't exactly productive.
I am ready to give up my post to Alex7 whenever he wants. I just thought that he wouldn't do the table :)
the post is yours...
Umarov Doro member of Tajikistan team Codeforces username is Alnair
Thanks.
Also Haitov Jamshed ( Jamik ) member of Tajikistan team participated in IOI-2012!
Although I'm a fake one of YuukaKazami, I want to say his(many people use her lol, maybe you can use her too) name is Lijie Chen.
Seems consistent with this and this. Yuuka Kazami on the other hand seems like a fictional character (and an alternate nickname) — very consistent with this. Fully support the change.
P.S. WJMZ8MR , when suggesting to change someone's name completely from what's written in the profile, please try to give at least some proof. But thanks.
I bet you can do well as a detective :).
My real name is LiJie Chen QAQ, Yuuka Kazami is my favorite character in Touhou >w<.(My avatar).
Also sillycross's name is HaoRan Xu.
what is the meaning of QAQ?
I'm not sure, but I think it's a smile face
In fact,it's a crying face
I didn't mean by smile is smiling , I meant it's emotion face , I used to call them "smile faces"
I didn't have enough info to do this. professorbrill your post is much better than mine, I only wanted to point it out...
Good luck everyone!!
Yusuf Hakan Kalayci(Turkey) was a participant last year. But, unlucky, he couldn't win. Thanks for EDIT.
Haitov Jamshed has so story too, TJK

professorbill, please add the new teams to the table..
He hasn't been on the site for 5 days.
Regardless, this week, I'll implement the addition of contestants to the future olympiads at IOI database, and the list of participants for all olympiads (which is currently absent) with all the information I have (country, links to CF/TC profiles, past achievements).
If there is any other information community would like to see in that table, I would gladly listen.
haha only georgian team has all members' ranks higher or equal to yellow
We have 2 months to make things better:)
@TMandzu All of us have turned yellow only recently, so you have to keep calm yet ;)
There is not announced Russian team. Beside that, Chinese average rating is more than 2200.
I said till now... I know that they have much stronger teams -_-

Slovakia:
Eduard Batmendijn (last IOI: gold)
Jakub Šafin Xellos (last IOI: bronze)
Jozef Marko jodik (last IOI: no participation)
Jaroslav Petrucha (last IOI: no participation)
Thanks for posting, however I'll wait to update it to my database due to things you mentioned in the second thread.
The reason for Czech Republic is that even when criteria is used to select a team, some people might refuse to go (we had a similar situation this year due to IMO), so I would really like to hear from someone who actually know the team.
As for Slovakia, while I understand the case of "unless **** happens", I've heard of "**** happenning on the last day of the camp", so as soon as you say it's finished, I'll update it.
But again, thanks anyway.
Actually, it was "unless magic happens", because the difference in points between 4. and 5. place was larger than the points for the last day's sub-contest. In this case, people refusing participation (or changes in scoring) are magic,
Anyway, got both confirmed. Those are the "regular" teams at least (there could always be changes due to a member running around castles, falling and breaking their hand or so :D)
OK, thanks, added both.
professorbrill , you might want to add both teams of Australia.
Is any country free to have two teams?
Traditionally only host.
Is there any important difference between the two teams of a certain host? Or are they both equal participants of IOI?
As far, as I understand second team is non-competitive. At least at Thailand they got "Сertificate equivalent to a gold/silver/bronze medal", instead of medal.
From IOI Regulations (2010 version):
S5.8 The Present Host may have a second, non-ranked, team at IOI’n.
The only 2 years when the second team won any medals and was ranked were 1989 and 1996. In 1989 Teodor Tonchev won the IOI from the second team with no mentions of anything unrated in the official IOI 1989 booklet and clearly stating that he won the main prize. In 1996 second team from Hungary received 4 bronze medals, and they were mentioned in the results table as bronze medals as well.
The team from The Netherlands:
From South Africa:
Janneman Gericke (new)
Shaylan Lalloo (new)
Paul le Roux (new)
Robert Spencer (no medal 2012) rspencer
Team Italy:
Thanks! I've also updated the database, and now it shows the difference between "No Medal" and "Unranked".
Top-4 from Belarus according to the results of the elections:
- Vladislav Podtelkin(vlad107)
- Konstantin Sokol(kostya_by)
- Sergey Kulik(CherryTree)
- Konstantin Vilchevski(vilcheuski)
This is not official information.
UPD This is our official team now.
Sorry, could you please clarify what do you mean by not official information? Is it like unofficial in a way that you know a team, but it's not officially published or is it like unofficial in a way that the team might as well change later?
Would like to point out to professorbrill that this is updated as official. Also adding that Vladislav Podtelkin won silver in 2012, while Sergey Kulik got bronze. Other two contetants are new to IOI.
The Croatian team is known now, a blog post about it
Team Greece has been added.
Egypt:
Oh. Can you explain this name for Yousef Salama then, please?
Youssef Mohamed Mohamed Ibrahim Salama, We got used to call him Yousef Salama.
Youssef Ibrahim == Yousef Salama.
Thanks! Merged. Left Ibrahim, because he's called like that in all IOI 2012 official documents.

Vietnamese team:
Em la nguoi Viet song a Nga va rat muon duoc biet o Viet Nam tuyen chon doi di thi lap trinh quoc te the nao a? Thi toan quoc roi chon top 4? Hay la co vai Qualification Rounds to chuc cho top 20 roi sau do moi chon top 4 tu 20 nguoi dua tren ket qua Qualification Rounds?
Viet them tieng Anh nua chu ko Codeforces community ghet minh mat.
I am a Vietnamese who lives in Russia. I am very interested in the way of choosing IOI participants in Vietnam. Are those the top 4 of the National Olympiad in Informatics? Or top 20 are chosen and then there are several Qualifications Rounds, based on the results of which the top 4 are chosen?
This year we had 3 rounds. Each round has 2 competition days. 1st round: 3 hours each day, 2nd and 3rd round: 5 hours each.
After 1st round, top 28 are selected. After 2nd round, top 6 are selected. After 3rd round, top 4 are selected.
Are there any specialized schools which provide strong candidates every year? Those schools organize training rounds for practicing, don't they? Is there any way I can find information, tasks from those Qualification Rounds for IOI? Website or anything like that?
Unfortunately, we don't have the official website for Vietnam Olympiad. Only problems in the first round (with unofficial testdata) are uploaded to http://vn.spoj.com/ (in Vietnamese, of course). For problems in subsequent rounds, you may better ask contestants who participated in (there are a few who are currently active on Codeforces).
Regarding your first question, We have a few schools that consistently produce good students every year (you can check this wiki) to see Vietnamese medalists and their high schools). Of course, each school has its own training program, training students from scratch during three years.
By the way, are you planning to go back to Vietnam for next year's selection? I'm just curious :)
Well, all these schools are familiar to me from my parents' stories about elite ones in Vietnam (my Mom told me if we were to return to Vietnam she would surely want me to get into one of those or Hanoi Ams).
Regarding my plans of returning: no I'm not returning to Vietnam since I have studied here in Russia from the 1st grade; currently I am in the 10th grade (Vietnamese 11th since we study only 11 years in Russia), and it must be a very foolish idea to return, though my parents had such plans after my 4th grade in Russia (Vietnamese 5th). Moreover, I am quite sure there many more talented people in my homeland. So I have no worries about the Vietnamese team.
But, to tell you the truth, I would like to participate unofficially :P
Mexican Team:
No IOI 2013 Facebook group this year?
If there's some group, please invite me: https://www.facebook.com/mdantasc otherwise, if you do want, i can create a group and invite everybody.
You might as well go ahead and do it MDantas, nobody seems to have created one yet.
Ok, I'll do it.
Group created: https://www.facebook.com/groups/362768537158225/
Be sure to post it on the IOI 2013 Facebook page.

Formally, this is unofficial now, because it should be approved by Ministry of Education. But this is just bureaucracy.
All four have no participations before.
Just out of curiosity, why do you need your team to be approved by Ministry of Education ?
Russia has a wide spectre of different national wide olympiads (informatics, math, biology, physics, languages, etc). All of them at organized by Ministry of Education and get some kind of government support. So, our national training camps are also sponsored and controlled by Ministry. It also provides some money for our olympic teams. As you can see, all big events are in the area of Ministry.
In short: bureaucracy, and there should be some formal paper for budget planning. "Approved" is a strong word here, I would replace it with "signed".
It's amazing how your country support the olympiads, I wish Brazil had that kind of support, it's really difficult to get some kind of support or just a little help from our country. We don't even get noticed when we got a really good result. All they cares here is about soccer and carnival, education is something that don't really matters in Brazil.
To tell you the truth, though we do get support in term of olympiads, the Ministry of Education always comes up with some stupid ideas which seem never to get approved, especially by the population. I hope they come up with crazy ideas concerning olympiads not so soon.
Are you talking about Brazil ? I've been doing Olympiads for quite a long time and not a single help from the government was given. One of my friend'ss team that went to 2012 World Finals ( ACM-ICPC) was hoping that someone from the government would help them to go to Warsaw, but no one helped and they had to spend their money and beg for some support from some companies. Right now I don't see the government interest in support olympiads.
I guess the situation's similar in most post-Warszaw treaty countries... as founding countries of many international olympiads, it's to be expected :D
In Slovakia, the bigger problem is how purely scientific olympiads are sligtly disadvantaged compared to new-style competitions that require you to sell your ideas and not show they're correct (often even hide that they're incorrect). And weird shit sometimes happens for no reason, like deciding that all olympiads will be held at the same place... I pity people who want to do multiple olympiads for several years, taking the same tours (post-competition programme) several times. The financial support from the government could be better, too. As you can see, we've also got our fair share of trouble :D
Team Finland:
May I ask why only 3 contestants?
Unfortunately, we don't have money to send a full team.
What? who do you mean by "we" ? your government?
The funding comes from the government and other sources. The problem is that algorithm programming is not very appreciated in Finland. If we played ice hockey, we would have no problems with funding.
In Latvia we have pretty much the same attitude. Fortunately, the tickets to the IOI are covered for us, but, as regards participation in the Baltic Olympiad in Informatics, usually zero support is given by the respective government authorities (as far as I know). Can't blame anyone, though, since the ice hockey team is the national priority (:
Tunisian team
sorry if it's annoying , I tried to put it as a link to this photo but CF system considered it as a photo
Tunisian team
Really?
how did you make it?
I just used the button "link" to put the photo but I was viewed as photo not link
maybe this bug has been fixed,
I remember with I posted my comment both photo and link was like this:
and CF system will detect it if it's link or photo (I think)
but now it's different from each other by prefix "!"

So, people don't like me posting updates to professorbrill to keep this table in sync. Oh well. As you wish.
I think as long as professorbrill keeps updating from your comments, they're still useful for us, I mean who cares about this topic, not those "dumb" downvoters.

champion still orange? Wow.
And he is from "Harvard University"? Are university students able to participate in IOI ?
It means prospective student, I think.
Gennady was in IOI last year when he was student of IFMO.
That's because IOI was in September last year.

Practice tasks for IOI 2013 are available. By the looks of it, this year they've decided to give some tasks.
Can anyone help with the second task?
First observation is that if you are going to stay in i-th country then stay for P[i] days because if you stayed for less then you haven't done anything.
Second observation is that if you stayed in i-th country and gained citizenship then after that you shouldn't stay in the j-th country if P[j] > Q[i] and if you didn't stay in any such country then the i-th country citizenship will remain with you, because if you visited the j-th country then you won't be able to visit the i-th country in this period and if you didn't you will be.
So let's say that we have a group of countries A, and we want to check if we can gain citizenship for all of them, let's iterate over A in decreasing order according to the value of Q, in every step we try to put the current country (call it i) in the best place possible, the idea is that if we stayed in this country as late as possible , less number of countries will be affected by the condition of this country.
Let's find the index j such that we can stay in the i-th country any time before we stay in the j-th country, we will stay in the i-th country right before the j-th country, so all the countries from the j-th to the last country will be affected by the i-th country condition, so all of them must have there P value <= Q[i].
Now we can check that we can gain citizenship of all countries of A, if after we sort A in decreasing order according to the value of Q, there is no two indices i and j such that j < i and P[i] > Q[j] and P[j] > Q[i].
Now let's sort all the countries that is given to us in decreasing order of the value of Q, first let's say dp[x] = the size of the largest subset from the first x countries such that we can gain citizenship for all of them then dp[x] = max(dp[x — 1], the size of the largest subset that we can gain citizenship for all of it and ends with index x) let's find using binarysearch the index y such that all the countries with index y and below have their Q value >= P[x], then we can include the subset dp[y] safely, and for the values from y + 1 to x — 1 we should include only the countries that have their P value <= Q[x], we can find this countries using segment tree.

Thanks very much, but I have question. What does the function
int queryreturn? I didn't understand it at all.In every node in the segment tree, let's say it represents the range [L, R], I store a sorted version of this range in the node, then when i want to find the number of elements in a range [s, t] that are < some value k (that's what the query method does), I find the group of nodes that add up to this range, and binary search on each of them to find the number of elements < k, and return the sum.
Update: team Slovakia, Eduard Batmendijn: CF handle Baklazan
The official list of contestants has been published. I and popoffka are currently working on getting the data in the database.
что-то команда Канады не очень то и "канадская":)
The full participant list was imported from the IOI website to the database. The leaders/deputy leaders were added to the delegations as well. The photos will be added at a later date.
Too Late ?? (I think no. Handles are not available here)
Turkmenistan :
1. Sylap accidentallygivenfuck Aliyev — 1997 — No participation
2. Begmuhammet Bega Kakabayev — 1996 — Bronze(2012)
3. Dovletgeldi 1O1 Aydogdyyev — 1996 — No medal(2012)
4. Ahmet turkmen Hudayberdiyev — 1996 — No participation
It would be nice to update the CF-color for all the participants at the start of IOI.
who knows the link to the online tours results?
