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. This event will take place at IBM/itpoint on the Altstetterstrasse 124 in 8048 Zurich-Altstetten at 16:00. It is open to the public and we especially inivite all parents, friends and colleagues of the participants to come and join us. 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.

We finished correcting the submissions for 2T and can therefore now publish the final results of the second round of SOI 2010. In the theoretical part the maximum points per task was 10, giving a total of 30 points for the theoretical part. We scaled those 30 points to 400 points (maximum of the practical part) and added them to the scores of the practical part. So the sum is your total out of 800 points.
The best 12 contestants (marked in bold) are invited to the SOI 2010 Finals, which are going to be held in Zurich May the 7th/8th and May the 21st/22nd.
The Second Round of SOI 2010 took place two weekends last March. For the theoretical part, 25 participants traveled to ETH Zurich and stood up to the challenge we prepared for them. They had 4 hours to solve three algorithmic tasks on paper. The goal was to invent a correct algorithm, which is as efficient as possible. The correctness stands above all, thus a good solution also gives a proof or strong arguments for the correctness.
The weekend after, one had to take the step from theory to practice. In a 5 hour contest, the participants had to solve 4 programming tasks from their homes. As always, the tasks were of an algorithmic nature and writing the code itself is usually the easier part than finding a correct algorithm. A participant was free to choose one of the languages C, C++ or Pascal (even though nobody preferred the last one). The submissions are judged automatically, which is to say that we prepared input/output cases for every problem and tested the submissions against it. Usually there is no feedback as to how many points the just submitted program scored, we enabled the full feedback mode for one problem, nonetheless. It was also this task (handangle), which was solved the most.
From the scores it seems that the tasks were quite difficult. A great deal of the participants finished with 100 out of 400 points or less. We, indeed, expected the tasks to be quite a challenge, thought, however, that more people would come close to the 200 points (by solving task super mouse, for example).
For the qualification of the SOI 2010 finals, we will combine the results of the practical and the theoretical part evenly and decide the top 12 participants of the second round, who are going to be eligible for the finals.
The results of the practical part are already available here: Results 2P

We are still correcting the submissions of the theoretical part.
The Helvetic Coding Contest is a Switzerland-wide programming contest organized by EPF Lausanne and mainly intended for university students. However, this makes it only more interesting for SOI-participants to take part, as you can show the university guys from ETH Zurich, EPF Lausanne and other universities from Switzerland how it is really done…
The Helvetic Coding Contest takes place March 13th in Lausanne and is organized for the first time this year. The main difference to SOI and IOI is that you can participate in teams of at most 3 people (but you will only have one pc to work on). We highly encourage everybody to form a team and take part in this cool new contest. Among the contestants will be some organizers of SOI and hopefully a lot of contestants, so you will definitely see some familiar faces.
Moreover, SOI is paying the travelcosts and participation fees (which are really low) for all SOI-participants, who qualified for the Davos-Camp.
If you are interested, either contact us or register directly at the Helvetic Coding Contest-Homepage below. Please just «SOI» as the entity you represent.

I am hoping to see you there.
