Since IOI 2014 participant list was released in mobile app a couple of days ago, I have processed it and it is now available in IOI database.
Almost all Codeforces handles were also imported from thread by accidentallygivenfuck — thanks to him for maintaining it!
Finally, the participant list now marks golds with 1st — 5th absolute ranks as such and sorts them appropriately.
UPD: It turns out that the information in the mobile app was incorrect/outdated. The database was updated. Contestant-wise, serious changes were made in teams from Colombia and Egypt.
Thanks a lot for your efforts to collect data about IOI participants! Hopefully everyone can imagine and appreciate the enormous amount of work involved in supporting the database, manually entering the data and checking for possible duplicates.
Here's a list of top 50 IOI 2014 participants by current CF rating and by maximal CF rating ever achieved (generated today, on July 5th).
The colombian team in the IOI database for IOI 2014 participants is wrong (it appears their same contestants as in IOI 2013, but they are now all four different); however, I don't know the correct names of the new participants :/.
I just compared the data from the database with the data from the official app and it's absolutely the same. So if the Colombian team really is different this year, someone must have made a (really weird) mistake when registering the team.
I think so :/ I actually talked with a colombian friend and he told me that any contestant of IOI 2013 will be present this year.
You are right, the information has been outdated. Thanks for reporting this. See the post update for more info.
my travel journey to Taiwan is going to start after few hours, it will be nice to meet you guys in Taiwan, good luck to everyone.
