В апреле 2012 года компания КРОК на базе проекта Codeforces провела свой первый открытый чемпионат по программированию, в котором приняли участие около двух тысяч человек из различных городов России. Цель этого проекта — поощрение самых талантливых и прогрессивных молодых специалистов и стимулирование интереса к сфере информационных технологий.

Компания КРОК активно участвует в различных социальных проектах. Особое внимание уделяется проектам, связанным с развитием ИТ-отрасли и продвижением ИТ-профессии. У КРОК имеется богатый опыт сотрудничества с ВУЗами, организации студенческих олимпиад, открытых семинаров и лекций. Этой весной «по мотивам» мировых чемпионатов был организован первый открытый чемпионат КРОК по программированию. Проект оказался успешным, и потому проведение подобных соревнований может стать новой традицией для компании. Стоит отметить, что компания КРОК не случайно выступила инициатором проведения чемпионата. В штате отдела разработки программного обеспечения работают свыше 100 профессиональных разработчиков, включая офисы в Москве, Санкт-Петербурге и Нижнем Новгороде. Отдел за свою историю успешно выполнил почти три сотни проектов, включая систему автоматизации переписи населения 2002 и 2010 годов, систему автоматизации ЕГЭ в более 20 регионах, ГАС «Выборы», ИСЭД администрации пермского края, отраслевую систему документооборота ГК «Росатом», интеграционную шину Сбербанка.

Всем привет!

Пришла пора опубликовать фотографии с прошедшего чемпионата. Напоминаю, 27-го апреля в гостеприимном офиса КРОК прошел финал Чемпионата Москвы и МО. Так как Чемпионат был открытым, то присутствовали не только москвичи — были участники из других городов России и даже из ближнего зарубежья.

Ниже много мегабайт фотографий!

Editorial.

Hello Codeforces!

I am glad to welcome you — both onsite and out-of-competition competitors — to the final round of Open Moscow Programming Championship By CROC. I am the writer of this round — Gerald, ivan.popelyshev and Delinur helped me in the preparation of the problems. This is my second round in Codeforces, so far, thanks to the Codeforces team and MikeMirzayanov for giving me this opportunity again!

Please note that this round is held in conjunction with its onsite counterpart, so its starting time may be delayed. Also, since MikeMirzayanov is very busy with the onsite contest at the moment to decrease the load (to avoid any disaster for the onsite competition), I apologize that you may not receive any email reminder about this match.

I've taken feedbacks from my last match into account, so the pretests will be fairly strong. The match should be more interesting for you if you decide to try and solve as many problem as possible, instead of stopping and hacking other codes early in the match :)

The rules below are copied-modified from Ripatti's post:

Competition will happen by usual rules of Codeforces, with hacks and score falling in process of time. The three championship winners will be awarded valuable prizes:

• 100000 rubles for the first place
• Apple MacBook Pro 15 for the second place
• Apple MacBook Pro 13 for the third place

Please remember that the round will be rated only for onsite participants and Division 1 contestants, since the problemset may be more tricky than usual (or it may not be :) ). Division 2 coders can participate, but it will not be rated for them.

There will be five problems ordered by approximately increasing complexity. The scores will be 500-1000-1500-2000-2500. Don’t forget that during contest your solutions will be tested on a small set of pretests. Testing on full testset will be after end of the round. Pretests can don’t cover all cases of input data, so you should test your solutions very carefully.

It is strictly forbidden to publish statements/solutions of the problems before round will be end. Also you shouldn’t to talk about problems, discuss some things about possible solutions of them. Let’s be honest! You can discuss problems after the end of round.

Good luck everyone! I will be watching :)

Hello everyone!

Today is the second round of the Open Moscow Programming Championship By CROC will be. Start is planned at 19:00.

All contestants who passed score no less than contectant of the 300-th place in the Round 1, can participate in the Round 2. Every other contestants can patricipate the Round 2 out of competition. Specially for contestants of the second division we prepared more easy unofficial problemset. The official problemset and the unnoficial one have some common tasks.

Some number of problems are waiting you. They are roughly ordered by the increasing complexity. Score distribution is standard for both divisions (500-1000-1500-2000-2500). Don't forget that during contest your solutions will be tested on a small set of pretests. Testing on full testset will be after end of the round. Pretests can don't cover all cases of input data, so you should test your solutions very carefully.

It is strictly forbidden to publish statements/solutions of the problems before round will be end. Also you shouldn't to talk about problems, discuss some things about possible solutions of them. Let's be honest! You can discuss problems after the end of round.

The round was prepared by Ripatti, havaliza, Gerald, RAD, MikeMirzayanov, Delinur.

Good luck for all!

UPD. We remind that the final of the Open Championship of Moscow and Moscow Region Programming (CROC) take place on April 27 in the office of the CROC. Note that CROC does not pay for the road and residence of the finalists. All participants must arrive at the final in the office of the CROC (Moscow) in the morning on April 27.

The first 50 participants on the results of the competition, which will confirm their participation in the finals, will be invited to final competition. You can confirm participation in the finals during the day after the end of Round 2.

It is recommended to fill the form, regardless of your results in Round 2, as large number of participants can reject the participation in the final.

Good day, Codeforces!

Today at 19:00 the Round 1 of the Open Moscow Programming Championship By CROC will start.

This is usual two-hour Codeforces round with hacks and decreasing values of problems. Everybody, who passed Qualification Round and registered for today’s round, has advanced to Round 1. The remain participants are allowed to participate in this Round out of competition. Round will be rated for everyone as usual. Contestants who gain a score equal to the 300-th place finisher score or greater will advance to the Round 2 (also you need to gain positive score).

You will find a few problems, roughly ordered by the increasing complexity. Score distribution is standard (500-1000-1500-2000-2500). During the Round the problems are judged only on pretests and system testing will take place after the end of the Round. The pretests do not cover all possible cases of input data, test your programs carefully!

Before the end of the round it is strictly forbidden to publish the problem statements/solutions/any thoughts and ideas about them elsewhere. It is forbidden to talk about the problems, discuss the statements and so on. Be honest and let the best men make it into Round 2. When the Round is over, you can discuss the problems and solutions.

It seems that this Round could be a bit hard for Div2 participants. Don’t forget that rating will be calculated only for participants, who make at least one submit.

In today’s round preparation take part: Ripatti, havaliza, haas, RAD, Gerald, MikeMirzayanov, Delinur. A huge thank you to all of them for their work!

Good round to everybody!

Hi everybody!

Let me remind you that on the 3rd of April, at 08:00 the Qualification Round of the Open Moscow Programming Championship By CROC will start.

At the Qualification Round you will find a few simple problems, roughly ordered by the increasing complexity. During the Qualification Round the problems are judged only on pretests and system testing will take place after the end of the Qualification Round (round continues for 24 hours). The pretests do not cover all possible cases of input data, test your programs carefully! The Qualification Round has no hacks or decreasing values of the problems.

The round will last for 24 hours, but it does not mean that we encourage you to spend all this time solving of problems. We hope that most participants will cope with the problems (or with most problems) in a shorter period of time. This duration of the round is chosen so that each participant could find a convenient time to participate.

Before the end of the round it is strictly forbidden to publish the problem statements/solutions/any thoughts and ideas about them elsewhere. It is forbidden to talk about the problems, discuss the statements and so on. Be honest and let the best men make it into Round 1. When the Qualification Round is over, you can discuss the problems and solutions.

You can register for the round at any time up to its end.

The results of the round will not affect the rating, non-competitive participation in the round is not allowed. However, all tasks will go to the archive after the end of the round.

Best of luck and enjoy solving the problems!

UPD: The contest is over! Thank you for your participation. We will remove cheaters soon and the results will become official. Unofficially, the Round 1 cutoff is 1950 points.

UPD 2: We have removed obvious cheaters and people who are under 18 years old at the time of registration. If your results have been removed in error, please contact me for clarification. Now, the Round 1 cutoff is 1900 points.
