About SOI

The Swiss Olympiad in Informatics is a programming contest for young people under 20 years of age. Since 1992, the competition has been offering computer enthusiasts a platform to match their skills with others who share their interest. At the same time, the Swiss Olympiad in Informatics also elects the Swiss delegation for the International Olympiad in Informatics. It might just be you representing our country at the next international event while getting in touch with participants from over 80 countries around the world!

Participation is worthwhile:

What is the SOI?

The Swiss Olympiad in Informatics is the national qualification for participation in the IOI (the International Olympiad in Informatics). The SOI aims to train and select four participants to represent Switzerland at the International Olympiad in Informatics.

SOI Team 2015 with Prof. Ron Rivest

The SOI is mainly organized by former contestants in close collaboration with the Chair of Information Technology and Education and the ABZ - Informatikunterricht of ETH Zurich. But of course the realization of the event also depends largely on the generosity and cooperation of our partners. And last but not least, we work together with all the national scientific Olympiads of Switzerland to nourish the hunger of young people for science.

What is the IOI?

The International Olympiad in Informatics is one of five scientific olympiads, that are supported by UNESCO. Each year circa 300 participants from more than 80 different countries compete to take home a gold, silver or bronze medal. Apart from the contest, there are also excursions and other special events each year.
