Let me say the customary phrase "The series of school online Olympiads have ended!"

The organization of all the Olympiads was supported by Yandex and ABBYY companies. Overall 6 competitions took place, three team Olympiads and three individual ones. It is now high time we looked at the results and found the Olympiad winners. The two nominations (team contests and individual contests) were ratified individually – in each of them the results of the participants’ best two of three performances. Here are the links to the total results in each nomination:

Overall about 750 participants from all over the world had been registered during the series. Of course, the majority of them were Russian participants. As we can see, about 180 teams took part in the team contests and more than 400 school students took part in the individual contests.

After discussion with the WCS organizers the results were decided to be calculated in the following manner. In the team contests 34 best teams (that scored more than 175 points) are rewarded. Among them
  • 8 best teams receive first degree certificates:
    1. Gennady Korotkevich team (Gomel, Belarus)
    2. PhTL №1 #1 (Saratov, Russia)
    3. despise_oimaster team (China)
    4. Minsk-1 team (Minsk, Belarus)
    5. LIT: LIT_1 team (Alexandria, Ukraine)
    6. Fisher is a ball! team (Perm, Russia)
    7. Gomel-2 team (Gomel, Belarus)
    8. Mozyr-1 team (Mozyr, Belarus)
  • The teams that win places form 9th to 19th receive second degree certificates.
  • And the teams that win places from 19th to 33rd receive third degree certificates (note that the 33rd place is divided between two teams).

School Team Contest #3 (Winter Computer School 2010/11) will be held on November 13 at 11:00 (UTC). This is the final team event of the series, and we will be glad to see both permanent participants and new teams.

The contest has been prepared by me, Artem Rakhov, Nikolay Kuznetsov and Ivan Fefer. All of us will soon go the ACM-ICPC regionals in St. Petersburg, and now the guys have to combine the preparations for the semifinals with writing problems for you. Special thanks for the translation of problems to Maria Belova.

Everyone can take part in it out of the competition (informal). Make up your mind :)

We decided to sum up contest results using the ITMO rating system, according to which team gets a score from 0 to 200 per contest. It will be used two best participations out of thee possible. I will not reveal secrets, saying that Gennady Korotkevich showed great results and secured the victory ahead of schedule!

Good luck in the upcoming competition, MikeMirzayanov and stern, but fair jury.

UPD. Statements in PDF: russian version and english version. The statements will be available when the contest starts.

Good day to everybody!

Welcome to School Team Contest #1 that will be held on the 24th of October at 11:00 MSK. The contest will be official for school teams as a part of the series of winter programming school olympiads (http://codeforces.ru/blog/entry/753), and it will be informal (and not rated!) contest for everyone else.

To compete officially, each participant of a school team must at first register personally, then you must create a team of registered participants, and when registration to the contest opens, you must register your team there too.

I hope that the problems will be interesting for school students with different level of programming skills, and not only for school students! Pay attention to some differences from usual Codeforces contests. First, the duration of the contest is 5 hours, and there will be standard ACM rules. Second, problems will not be sorted in increasing order by their complexity, they will be shuffled. So your first problem for you is to find an easy problem :)

The authors of the problems are Mikhail Mirzayanov and me. Thanks to Gerald Agapov, Polina Bondarenko and Artem Rakhov, who helped me to prepare the round. Also thanks to Maria Belova for translating problem statements into English. We all are from Saratov State University.

Good luck!
 
UPD: After the contest start, it will be available PDF-versions of the statements:
UPD: The contest is over. The results are available. The winner in both official and non-official standings is Gennady Korotkevich, who has solved all the problems. Congratulations to the winner! The problem analysis is available.
