The Swiss Delegation returned last Saturday from the 22th International Olympiad in Informatics, which took place in the renowned University of Waterloo in Canda.

The Swiss Delegation (f.l.t.r.): Josef Ziegler, Thomas Leu, Lazar Todorovic, Sandro Feuz (team leader), Adrian Roos (deputy leader), Nikola Djokic

The SOI 2010 is approaching its end. Right now, as I am writing this, the participants of the SOI 2010 finals are sitting on the last of the four five-hour long contests.
After the contest ends, we are going to honor people which have achieved great things for SOI and there will also be announcment of the winners of the SOI 2010 Finals including the awarding of the medals.

We're also looking forward to our guests of honor from ETH and our supporting partners, who will award the medals to the winners.
After the announcment of the rankings all participants of the SOI 2010 and our honor guests are kindly invited to a dinner.
The first weekend of the SOI 2010 Finals was held 7th and 8th of May at the Credit Suisse Business School in Zurich. Just as the years before our host was very accommodating and provided an excellent environment for the first two five-hour contests of the SOI 2010 Finals.
We had prepared 8 tasks, which emerged to be a hard nut to crack for most participants. The results for both days can be found here: Results Finals 1
We also prepared a graphical representation of the individual submissions, so you can track each participants performance over time Graph Finals 1
The second finals weekend will be on 21st and 22nd of May and be hosted at IBM/itpoint. It will again consist of two five-hour contests with 4 tasks each. After the contest on the 22nd of May there will be the medal ceremony of SOI 2010 and we will announce the Swiss Delegation for the International Olympiad in Informatics 2010 in Canada. There will various representatives from both some of our sponsors as well as ETH Zurich present.
