Second Round over

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.

Helvetic Coding Contest

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.

You find all information on their website: http://hc2.ch/index.php

I am hoping to see you there.

The Davos-Trainingscamp is over and we hope everybody had a good time. The trainings-possibilities were again unbelievable having programming experts from Switzerland, Slovakia and Russia as coaches. Check out some impressions here: Pictures Davoscamp 2010

The following students participated successfully in the first round of SOI 2010 and qualified for the second round:

SOI Day 2010

The SOI-Day is over and we hope everybody had a good time. We will upload the presentations and an anonymized ranking soon, moreover the VSWO composed a press information: Press Information(german)
