Just to inform you that you have 7 more days until the deadline for the practical and theoretical track of the first round of SOI 2011.

We prolong the deadline for the creativity task (multisnake) by two weeks in order to give you the chance to participate or enhance your programs further.

Note that you can (and should) submit earlier, so if you have problems with the submission, you can contact us. The submission forms will be closed immediately after the deadline.

It is, if unavoidable, possible to submit multiple times in case you find bugs in your submission. We will only look at the last submission for each task though.

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

Between the 14th and the 21st of August, over 300 youngsters from 83 countries came together to compete in the most prestigious programming contest for high-school students in the world. The Swiss Delegation consisted of

  • Samuel Grütter, Gymnasium Kirchenfeld, BE,
  • Timon Gehr, Kantonsschule Trogen, AR,
  • Alain Vaucher, Collège Sainte-Croix, FR und
  • Josef Ziegler, Kantonale Mittelschule Uri, UR.

Apart from the contest itself, which took place on two days with four tasks each, the organizers planned a great deal of activities, such as: An excursion to the Niagara Falls, a visit in Canada's Wonderland as well as various lectures on different subjects in computer science.

The four swiss contestants showed that they can stand the peace of the international competitors, even though we did not score a medal this year. We congratulate all swiss representatives on their performances.

The official ranking of IOI 2010 is available on the official website.. An inofficial –but more informative – ranking is available on SnarkNews.
