Today Saratov delegation will go to the championship's finals. As you remember, we've been planning to go to Sharm El-Sheikh since January, watching their great February revolution anxiously. As a result, the finals were moved to Orlando (Florida, USA). Our delegation got a little smaller too, as May is a hot month and it's a long way from Russia to the USA.

Our team is famous on Codeforces. And that's not surprising! Just look at them:

• Maxim Ivanov (e-maxx) spends considerable time among the top rated users and among the top contributors. Many know his wonderful site http://e-maxx.ru/, of course. Attentive users recognize him as a determined bug filer in gcc issue tracker and an author of some contests. Maxim is on the fifth year in SSU Mechanics and Mathematics Department and his interests include "programming, programming and... oh yeah, programming :), zen, taoism, philosophy, psychology, the bike".
• Artem Rakhov (RAD) is known as the Codeforces problems' coordinator, the participant of all on-site prestigious competitions (TopCoder Open, Google Code Jam, Faceboook Hacker Cup) and a great Cola fan. Personally, I've known Artem since the eight year at school and I shudder to think how many problems he has solved since then :)
• Nikolay Kuznetsov (NALP) is known as the author of several rounds and the one who fights ardently for clear statements. He used to be in one team with Artem back at school days. I remember how surprised I was when I learned that he got to TopCoder High School Competition. Nikolay is a third-year student of the Department of Computer Science and Informational Technologies of SSU and he is my student. On July, 10 I exam him on the theoretical course in Programming Methods. By the way, Kolya, let me remind you that you haven't yet got the pass for the practical work!

Besides, the team has me as the coach and Antonina Fedorova as the team leader.

I will do my best to keep you up to date on how the trip's going (mostly on the actual finals, of course). However:

I urge the participants of the event not to keep their interesting impressions hidden and bottled up. I want you to share them. For example, you can publish them on Codeforces!

As a conclusion to the entry, I want to ask a question to those who have already planned the whole trip. As far as I understand, the couple of days before the finals in Orlando won't be spent uselessly: there are some grand amusement parks around. I've got a question to those who are prepared and to those who are keen on that: which place will be most interesting for the ACM-ICPC team? As far as I understand, the tickets to those parks are not exactly cheap, but in one can get a discount now and then - how should we purchase the tickets?

Just in case I inform the Saratov residents that we leave today, on May 23, on train 9.

Hello, dear participants and spectators!

Let me remind you that the elimination phase of the open programming competition "Yandex.Algorithm" comes to an end. With it this means that the time for the most important event of the phase has come: the elimination round for the finals (finals will be held at the Yandex Summer School)! This means that today two hundred best participants of the tournament (based on the results of the previous qualification rounds) will compete to get into the top-15 of the world olympiad programming community.

We hope that the round will be appreciated not only by the participants but also by the spectators, who will have the opportinity to watch the events developing for at least two hours.

Please, pay attention to the problems' costs: 500, 1000, 2000, 2500, 2500. I also advise you to read all the statements, as the choice of the costs and the order is certainly subjective.

Round will be rated for all the participants (including those competing hors concours).
Good luck to the participants. The problems are going to be rather hard, so you'll have to do your best!

I also wish a spectacular round to the rest!

Round is over. According to the results, 20 participants solved at least three problems, and just one (the winner) was able to solve the fourth. The first three places were taken by Petr Mitrichev, Gennady Korotkevich and Sergey Kopeliovich. Congratulations!

In addition to this, 15 leaders advanced to the finals: Petr, tourist, Burunduk1, ivan.metelsky, dzhulgakov, e-maxx, LayCurse, rng_58, pieguy, zeliboba, ktuan, levlam, wata, dolphinigle, Progger .

Problems proved to be rather tough. Here's the full analysis.

We are glad to welcome all contestants of a qualifying contest "Yandex.Algorithm 2011 - Round 1".

Today's round authors are Vitaly Goldshteyn, Ignat Kolesnichenko, Stanislav Pak and Denis Yarets. All we are employees or interns of Yandex. We really appreciate Artem Rakhov, Maria Belova and Mike Mirzayanov who helped us to prepare the contest. We hope that our tasks will be quite interesting and you will get much fun solving them.

As you may know top 200 contestants after this round will be able to continue fighting for spots in the final round.

Please pay attention that as well as during the previous qualifying round Codeforces functionality will be a little cut down for the time of the competition. Do not worry, all will return into place after the end of the round.

Round will be rated for the official participants, and for those who failed to qualify and participate out of competition (unofficial).

Welcome to Codeforces Beta Round #72.

Hello!

Now you can view rating statistics for specified country and/or city on the ratings page. But there are also separate pages for rankings of the countries and the cities themselves (links to them are in the sidebar "Top rated").

Rating of a country (city) depends on participants ratings from a country (city) and calculated by the following simple formula:

where N is a minimum of 100 and number of country (city) participants, and K = 0.75.

I'm glad to welcome all fans of programming!

The second qualifying round Yandex.Algorithm will take place today, and it was prepared for you by Artem Rakhov, Michael Mirzayanov and me.

Please pay attention that as well as during the previous qualifying round Codeforces's functionality will be a little cut down for the period of the competition. Don't worry, all will return into place after the round termination.

I remind the best 500 participants pass in Yandex. Algorithm 2011 Round 1 which will take place on May, 20th at 19.00

Good luck!

Hello.

This round will start Yandex.Algorithm 2011. The problems of the round were prepared by me, of course, with the help of the Codeforces team and Yandex.

I hope you enjoy the problems and their solution will start a successful performance at the tournament.

As you have already noticed — the system operates in a somewhat truncated form. We decided to run it in safe mode and turn off some functionality at the time of the contest. After the round everything will be back.

I recall that the top 500 participants will receive a ticket to the first online round of the Yandex.Algorithm. However, if you do not get to qualify at this time, do not despair — you can participate in the second qualification, which will be held on May 6 at 15:00 (UTC).

I wish you have a fun,
MikeMirzayanov

We are glad to introduce Yandex open programming competition "Yandex.Algorithm" hosted by Codeforces. The competition starts on May 4th and will consist of two qualification rounds, two online rounds and a final onsite round. Some of the rounds are created by Yandex employees. The onsite round will be held at the Yandex Summer School in Distributed Computing in Moscow Institute of Physics and Technology.

Any registered member of Codeforces can participate. There will be 5 rounds, 2 hours each. 15 winners of the last online round will be invited to participate in the Summer School and in the final round of Yandex.Open. 70 best participants will get T-shirts.
