International Olympiad in Informatics – Statistics

This is an International Olympiad in Informatics database.

This site is intended to give anyone an opportunity to easily contribute the missing data. All changes will be checked before inclusion. Please, create a new person only if you're sure that he or she isn't already in the database. Currently, the big goal is getting the lists of all participants and leaders, as I already have all medalists. For some countries full data is obtained – check the country list for more information.

If you have a correction that is not yet supported by the system, bug report, feature request or any other related information, please contact me by e-mail.
