International Olympiad in Informatics – Statistics

This is an International Olympiad in Informatics database. Please note that the site is still in development and features may be added at any moment.

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 there is a goal of getting the lists of all participants, as I mostly have medalists only.

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. For feature requests, please note, that team leaders, guests, task statements, tests, solutions, task authors, organizers, press releases are already planned to be developed in the nearest future.


For ensuring better country statistics, there are 2 countries in the database which might appear different in official data. The Federal Republic of Germany appears as Germany in 1989–1990 and the Federal Republic of Yugoslavia appears as Serbia and Montenegro in 1992–2002. Furthermore, at IOIs 1989 and 1996 the second and third teams are ranked and they received the medals, as far as I know.
