Concerning IOI Statistics (again)
April 14, 2014

At the IOI statistics page there is already collected a lot of information about previous IOIs. However, also lot of information at the moment is missed like names of contestants without medals, names of team and deputy leaders, guests etc. There is also a possibility to add photos of IOI participants. Some names in the system may be incorrect (especially having diacritical signs and letters not presented in the English alphabet) - please correct them. At the moment the English-like names are allowed (diacritical letters derived from English alphabet are allowed like ā, ä, ł etc.). However there is also a possibility to add an alternate name, which can be in any language you like and this will be searchable in the future. So if you have this situation you can also submit latinized names as well as native ones. You can add all this information by yourselves - the interface for adding or editing information is simple enough - just try it out! However, if you have missed information in any other appropriate form (text file, MS Word document, MS Excel spreadsheet, etc.), just send it to us (the best destination would be Eduard Kalinicenko, and give some days for processing.

If you can fill any of the blanks in the whole IOI history picture, please, do it! At the moment at the country list there is a following colour code for the status of the information: red if no information has been verified as complete; yellow if only information about contestants is complete but leaders are missing or incomplete; and green if everything is OK. We would be glad if the responsible people for their countries will at least provide full information for their own country. It's only 26 years, so it's possible, but the further away we go, the harder it'll be to collect, so let's do it once and for all. In case if you have any questions or problems, do not hesitate to ask Eduard Kalinicenko ( or Mārtiņš Opmanis (, you can also meet me in present at IOI 2014.).
