Hello, this is Egor. Today we are starting previewing some teams from ACM ICPC World Finals in Marrakech that, by my opinion, have most chances to win gold medals. First to go is Lviv National University team LNU Penguins.

Some trivia: Lviv NU participated just 2 times, but got gold one of those times, in 2008. One of participants of that team, Vasyl Biletsky, is current team's coach (but we should note that he actually was his own team's coach in 2008 as well).

This year team qualified to World Finals as winners of SEERC. They are currently 11th in OpenCup standings (do note, however, that there are many teams in that standing that are not ICPC eligible for one reason or another).

Roman Bilyi (TC: 2513, CF: 2672) participated in Russian Code Cup Finals in 2014 and won Bronze in Snarknews Winter Series 2015

Vitaliy Herasymiv (TC: 2206, CF: 2356) won Silver in IOI 2012

Bohdan Pryshchenko (TC: 2269, CF: 2348) won Gold in Snarknews Winter Series this year and Silver in Summer Series last year.

I believe this team has decent chance to clench gold, about 60%, while their chances to win are slim, about 1% or so.

Stay tuned for tomorrow as we will look at our next team from University of Zagreb!

1:39 And finally he is successful. Meanwhile Ali Haghani tries to solve H. No luck as of yet

1:34 eatmore still debugging E — one of his asserts fails

1:22 eatmore debugging samples on E. This is also the problem I had not solved during test round (and still don't know how to solve)

1:18 No much happening near the top at the moment

1:00 One more problem is "opened" — problem C. Kudos to Ali Haghani

This year is 3rd edition of Bayan Contest.

Inaugural contest took place in 2011. About 800 university and high school students from all Iran tried to qualify for the finals through 2 online rounds and best 30 of them participated in the finals at Bayan offices in Tehran. Seyed Hamed Valizadeh won university stundents contest while Saeed Ilchi won high school part.

Next time Bayan decided to hold international contest. Codeforces was used to select international participants while Bayan's own system was used for selecting Iranian finalists as well as for the final itself. This time 1286 participants from 54 countries and 1728 from Iran tried to qualify and 8 international and 16 local finalists arrived to Parsian Azadi Hotel on February 16th 2013 in order to decide who is the best. peter50216 won the contest, cerealguy was second and I took the third place

This year 10266 participants from 103 countries tried to qualify. Tomorrow 60 finalists will once again clench for the title in Parsian Azadi Hotel conference room. Who will be the winner? Post your favorite in the comments.

Yesterday we arrived to Tehran Imam Khomeini International Airport.

eatmore was on my plane from Moscow, while we also met Ra16bit in the airport who arrived from Minsk.

After rather long process of aquiring visa and going through passport control (we arrived at 3:25 AM, but only got in taxi at 6:20) we got to the Parsian Evin Hotel where participants would live. Contest itself would take place in nearby Parsian Azadin Hotel.

After sleepless night I slept for most of the day.

Stay tuned for updates as today is excursions day.

Hi there!

As you probably know this is the second time Bayan opens it's programming competition to international coders. 2 years ago I participated myself and ended up taking 3rd place. This time around I'll be your blogger.

In this first post I want to give you some useful tips and links to know more about Iran and, if you won trip to Iran, what would you need to know.

Iran is a country with very rich history. Through the ages it participated in Greco-Persian wars, accepted Islam, was under Shah rule and now known as Islamic Republic of Iran since revolution in 1979.

Tehran, capital of Iran, is modern city, but with a lot of historic places throughout the city, like palaces of last Iranian Shahs, which is now museum complex or Grand Bazaar, both of which contestants visited 2 years ago.

As for food, get ready for some tasteful Iranian cuisine. I'd especially recommend lamb kebab.

Now, if you want to use your usual websites like Facebook while in Iran I'd recommend to take care of VPN service in advance. There are many options around Internet.

Finally if you want to stay online while on the go in Tehran I'd recommend visit this page about SIM-cards and data plans in Iran (refer to comment section).

Just fyi. Migration ended

Just FYI

Объявлено расписание на следующий год

Отбор 8 февраля, финал 2-4 мая

UPD: Уникальный шанс! Всего за 40 евро за ночь сдается кровать в твин номере в Hilton West End в Будапеште на 2-5 мая. Включает завтрак, интернет и, скорее всего, доступ в executive lounge. Petr будет жить в том же отеле

Финалисты:

Вот уже несколько лет в ACM сообществе считается нормальным выставление тайм лимита в 2 от времени работы авторского решения. Это неплохо работает в соревнованиях, проводимых по правилам АСМ (однако по моему мнению, стоит выставлять по среднему геометрическому от авторского и того, что не хотелось бы, чтобы прошло)

Однако мне кажется, что в соревнованиях, где результат итогового тестирования не известен до конца контеста такой вариант неприемлим. Локально на тл особо не потестишь, тестирование на макс тесте в запуске довольно трудоемкая штука, и когда тебе кажется, что попал в авторскую асимптотику ты этого делать скорее всего уже не будешь

Конкретно для Codeforces мне кажется разумным 2 варианта — либо ставится минимум 5х от авторского, либо макс тест добавляется в претесты. Мой коментарий про это в посте 200го раунда заминусовали, мне хотелось бы выслушать аргументы тех, кто не согласен с этой точкой зрения

15:24 — Closing ceremony will start shortly and you can watch it on ICPC Live. That's probably it for this translation. Bye-bye, see you soon

13:59 — Petr's blog for today

12:15 — That's it for Dress Rehearsal. Tune in tommorow. Bye-bye, see you soon

12:07 — Contest is over. Results should be availabe shortly

12:00 — Peking University

11:31 — I now accept requests for team photos ;)

11:28 — NRU ITMO:

11:25 — Taiwan National:

11:23 — SPb State:

11:16 — Scoreboard is frozen for the last hour, let's have some more photos :) Moscow State:

11:11 — Problems are same as last year, with slight change in wording

11:09 — Scoreboard is available online (tip of the hat to SuprDewd)

11:03 — Teams previewed in this blog are now placed like this:

2: Shanghai Jiao Tong, 10

3: Tokyo, 9

4: Moscow State, 8

7: SPb SU State, 8

14: Taiwan, 7

17: NRU ITMO, 7

11:00 — Shanghai Jiao Tong:

10:55 — Current leaders:

10:48 — Stanford leading with 10, Shanghai, Moscow and Tokyo with 8

10:40 — Stanford and Shanghai Jiao Tong lead with 8, Tokyo, Moscow and National University of Singapore with 7

10:36 — In the meantime NRU ITMO is 72nd with 2 problems solved

10:34 — All problems are now available in Kattis. Problem J is solved as well which leaves us with only one task not solved by anyone — Problem H. Stanford is leading with 8, Tokyo second with 7

10:30 — Only H and J are not solved as of yet. National Taiwan is close to solve J though — they only have problems with output format. And H is Power Tower again!

10:28 — B, F and E are now solved as well. Tokyo and Stanford are leading with 6

10:22 — First 8 problems are available on Kattis. In the meantime Stanford and Tokyo solved 5 problems, SungKyunKwan, Moscow State, Tehran and Southern California solved 4

10:18 — And now with 5

10:16 — Stanford University is now leading with 4

10:13 — C is solved as well. Shanghai Jiao Tong University is leading with 3. First two problems are available in Kattis

10:11 — Problem A is now available on Kattis for you to solve!

10:09 — A, D, J and K are all solved now as well. University of Chicago is in the lead with 2 solved tasks (and unsuccessful attempt on A)

10:08 — SungKyunKwan University is first team to solve Problem I

10:07 — Problem L is quite easy — given set of ints, you need to find maximum, minimum and their difference

10:05 — Six teams got problem L correct already

10:02 — Contest is started. No submissions yet

9:57 — One more delay, but this is business as usual. Currently contest in the state of "Two minute hold"

9:52 — Teams are currently being instructed. 5 minutes before the start

9:47 — Tune in tommorow for ICPC Live

9:23 — It seems Dress Rehearsal would be a little bit delayed and will start in 34 minutes. Currently teams are exiting arena and will reenter it shortly

9:13 — Remember, this year you can submit problems yourself from both Dress Rehearsal and main contest — just go to Kattis judjing system

9:10 — Teams are currently called to stage in turn by Bill Poucher and got photoed with World Finals Cup and Bill himself

8:51 — Hi! Dress Rehearsal will start in 39 minutes, stay tuned

Hello from St. Petersbutg where long awaited World Finals were officially opened at last.

Before the openning there was lunch near Anichkov palace, courtesy of Yandex, from which I have very cute shot of 2004 World Champion, Pavel Mavrin a. k. a. pashka

The openning itself took place in Alexandrinsky Theatre, one of the oldest in Russia. It was for the most part quick-paced, with a lot of music and art, including a part of ballet and sand drawing.

And now the main part — for the first time ever everyone in the world can have their chance to solve World Finals problems and submit them for testing. Starting 15 minutes after scheduled contest start, at 6:45 GMT on July 2nd (Dress Rehearsal) and 3rd you can submit your solutions to Kattis judjing system, the very same system used by World Finalists themselves. Also do not forget to tune in to ICPC Live and this blog, where I will provide live coverage as well.

Bye-bye, see you soon!

So, what is the last team I want to preview. Do you have any guesses? So many variants... Well, you must have guessed it right — it is SPb NRU ITMO 1.

Let’s start with small facts about each of team members:

• Mikhail won several trips to the next TCO through various side competitions (like photo competition) during TCO 2011

• Niyaz tweeted in April: “Playing dice with Gennady. This is the only game in which he can possibly lose”

Well, I cheated — one fact for two teammates :)

So, 2 of its participants are world champions already. And the third one will probably be. Why everyone thinks they will be champions again. Only once this team was behind another World Finals team in 2013. They won 13th OpenCup with overwhelming advantage (150 points ahead of second place, just 20 points shy of perfect score), although team finished third in previous edition. 7 wins and 4 second places on stages, OpenCup onsite win, NEERC championship — and that’s all in just 10 months. Well, during last OpenCup they ousted a team that featured 2 TCO, 2 GCJ, 2 Hacker Cup and 3 World Finals wins total. So, does anyone else have a fighting chance?

Well, yes. They are humans after all (despite some rumors). And World Finals are known for tricky problem sets. Well, in 5 days we’ll see.

Line up:

Mikhail Kever — Codeforces rating 2530, TopCoder rating 2969, 2012 World Champion, TopCoder Open 2011 finalist, Google Code Jam 2013 finalist, Facebook Hacker Cup 2012 and 2013 finalist

Niyaz Nigmatullin — Codeforces rating 2523, TopCoder rating 2818, 2012 World Champion

Gennady Korotkevich — Codeforces rating 3088, TopCoder rating 3657, TopCoder Open 2013 semifinalist, Google Code Jam 2013 finalist, Facebook Hacker Cup 2013 finalist, 6 time Gold (2007-2012, 1st place in 2009-2011) and Silver (2006) medalist in IOI.

Gold chances? Well, 95%. There is always 5% chance for something really odd to happen

Only two previews remaining, and today’s team is National Taiwan University +1 ironwood branch. This team already participated in World Finals in 2011 and had not won medal with 6 problems solved, but they make good use of this 2 years with outstanding progress in both personal and team competitions.

In 2010 team finished 3rd in Kaohsiung and 1st in Jakarta Regional Contests. In 2011 they placed 1st in Kuala Lumpur and 2nd in Hsinchu Regional Contests, but another team from the same university was selected. In 2012 they won both Kaohsiung and Jakarta Regional Contests. After Jakarta regional they were interviewed, you can view it here.

Line-up:

Pi-Hsun Shih — Codeforces rating 2823, TopCoder rating 3158, TopCoder Open 2013 Semifinalist, Gold medalist in 2009 IOI.

Che-Yang Wu — Codeforces rating 2229, TopCoder rating 2154, Gold (2008) and Silver (2009) medalist in IOI.

Han-Jay Yang — Codeforces rating 2463, TopCoder rating 2790, TopCoder Open 2013 Semifinalist, VK Cup 2012 Finalist, Gold (2008) and Silver (2007) medalist in IOI.

Pretty impressive results in regionals (they had beaten University of Tokyo team in Jakarta) and recent personal result (peter50216 is second in Codeforces rating, kelvin and peter50216 qualified to upcoming TCO onsite) make them quite dangerous. I will give them 60% chance for Gold.

I found this near my subway station

Следующая команда — университет Токио, название команды — «University of Agitsune». За названием стоит целая история. Члены команды называют себя в честь трех животных — кролик (по-японски usagi), угорь (unagi) и лис (kitsune). Если сложить кролика с лисой, то будет usagitsune. Если сложить угря и лиса, будет unagitsune. Теперь, если мы заменим различающиеся буквы дефисом, мы получим u-agitsune. А коль скоро университет Токио иногда называется U-Tokyo, можно по обратной логике получить название команды (благодарим qnighy за предоставленное объяснение).

В прошлом году два её члена принимали участие в OpenCup в команде с названием «Kroliki». Это не просто совпадение, ведь Макото Соеджима изучает русский. В общем рейтинге ребята завоевали седьмое место, а на этапах — одно второе и одно третье место.

Эта команда первой финишировала в своем полуфинале (Tokyo Regional Contest), опередив второе место на одну задачу, а на Kaohsiung Regional Contest — они завоевали третье место. Также они оказались первыми на Japan Domestic Contest.

Состав команды:

• Казухиро Хосака (Kazuhiro Hosaka) — рейтинг Codeforces 2400, рейтинг TopCoder 3101, финалист TopCoder Open 2011, финалист Google Code Jam за 2009, 2012 и 2013, финалист Facebook Hacker Cup 2011-2013, завоевал золотую медаль на Международной олимпиаде по информатике за 2008 и 2009 гг., а также залотую (2009) и серебряную (2008) медаль на Международной олимпиаде по математике.

• Кенсуке Иманиши (Kensuke Imanishi) — рейтинг Codeforces 2436, рейтинг TopCoder 2614, финалист Google Code Jam 2013, завоевал серебряные медали в 2010 и 2011 гг. на Международной олимпиаде по информатике.

• Макото Соеджима (Makoto Soejima) — рейтинг Codeforces 2814, рейтинг TopCoder 3468 (на данный момент является админом алгоритмов TopCoder), победитель чемпионата TopCoder Open за 2010 и 2011 гг., победитель чемпионата Google Code Jam 2011 и финалист 2010 и 2012 гг., финалист Facebook Hacker Cup 2011 и 2013 гг., финалист VK Cup 2012, завоевал серебряные медали на Международной олимпиаде по информатике за 2008 и 2009 гг., 3 раза становился золотым (2007-2009) и бронзовым (2005) медалистом на Международной олимпиаде по математике.

За личные достижения участников эта команда несомненно является одной из фаворитов. Мне кажется, что у них примерно 70% шанс завоевать золото.

Давайте познакомимся немного поближе с командой SPbSU 4 . В таком составе команда выступает уже второй сезон. В прошлом году Егор Суворов ещё учился в школе, то есть в ACM-ICPC участие команда не принимала.

Это единственная команда-финалистка, обогнавшая NRU ITMO в командном соревновании этого года – они победили на украинском этапе Открытого Кубка. Последний сезон Кубка они завершили на третьем месте, а вот два предыдущих сезона завершили на 9-ом и 2-ом местах (на 3 балла опередив NRU ITMO). За этот сезон ребята одержали победу на 3 этапах и занимали второе и третье места. На последнем NEERC команда заняла 4-ое место (решив 4 задачи за последний час), несмотря на то, что за минуту до конца ребята были на втором месте.

Список личных достижений также великолепен:

• Егор Суворов — рейтинг Codeforces 2607, рейтинг TopCoder 2895, финалист Facebook Hacker Cup 2013, финалист VK Cup 2012, завоевал серебряную (2011) и золотую (2012) медали на Международной олимпиаде школьников по информатике.

• Павел Кунявский — рейтинг Codeforces 2564, рейтинг TopCoder 3019, финалист Google Code Jam 2013, завоевал золотую медаль (3-е место в общем списке) на Международной олимпиаде школьников по информатике в 2011 году.

• Дмитрий Егоров — рейтинг Codeforces 2397, рейтинг TopCoder 2773, участник раунда Wild Card Round на TopCoder Open 2012, Завоевал серебряные медали как на Международной олимпиаде школьников по информатике, так и на Международной олимпиаде школьников по математике в 2011 г.

В целом, думаю, это команда, как и некоторые другие, имеет реальный шанс одержать победу на чемпионате мира. В то же время, эта команда может выступать с разными результатами, так что думаю, у них 50% шанс взять золото.

Вторая на очереди команда — команда Мифрил из университета Shanghai Jiao Tong. В целом, об этой команде мне известно не слишком много подробностей. Этот университет трехкратный чемпион мира — победы в 2002, 2005 и 2010 годах. В соответствии с правилами ACM-ICPC студент может принять участие не более чем в двух финалал, но насколько я слышал (поправьте меня, если я неправ) согласно сложившимся в Китае правилам студент не может принимать участие более чем в одном финале мира. Поэтому Bin Jin начал как замена в своей команде.

Университет SJTU победил в соревнованиях Jinhua (опередив второе место на две задачи) и полуфинале в Дхака. В Битве Гигантов (командном матче между Россией и Китаем) они завоевали самое высокое место среди китайских команд (3-е место).

Состав:

Xiaoxu Guo — pейтинг Codeforces 2264, pейтинг TopCoder 2485

Bin Jin — pейтинг Codeforces 2428, pейтинг TopCoder 2743, победитель TopCoder Open 2009, финалист Google Code Jam 2011, член команды-победительницы ACM-IPC World Finals 2010

Jingbo Shang — pейтинг Codeforces 2309, pейтинг TopCoder 2813, финалист VK Cup 2012, финалист TopCoder Open 2012.

Эта команда уже показывала высокие результаты, и, что важнее, имеет опыт крупных побед. Думаю, у них, по крайней мере, 60% шанс завоевать золото

Начнем со знакомства с некоторыми командами-участницами финала. Я напишу про 6 команд, которые, по-моему, являются фаворитами на золотые медали. Впрочем, всякое случается. Смело выкладывайте 6 (3, 12, n) ваших любимых команд в комментариях.

Начнем со студенческой команды Московского государственного университета Moscow SU ST. Её название получило широкую известность и имеет богатую историю. Моя команда, Moscow SU x13, соревновалась с одноименной командой. Обычно команда состоит из саратовских студентов МГУ. В данном составе команда уже второй раз участвует в финале. В прошлом году они заняли 10е место и получили бронзовые медали. На последнем NEERC они отослали код в последнюю минуту (даже в последние 5 секунд) – и заняли 2-е место, повторив успех 2011 года. Они выиграли и крайний четвертьфинал в Москве.

За последние 6 сезонов OpenCup они занимали 7-е, 8-е, 5-е, 6-е, 4-е и 4-е места в общей классификации, 2 вторых места и 6 третьих мест на отдельных этапах, а также третье место в финале 11-го OpenCup.

Впечатляют и личные достижения участников команд:

• Сергей Федоров — рейтинг Codeforces — 2406, рейтинг TopCoder — 2802, участник wildcard-раунда на TopCoder Open 2012, завоевал 2 золотых медали (в 2009 и 2010 гг.) на международной олимпиаде по информатике.
• Александр Калужин — рейтинг Codeforces — 2206,рейтинг TopCoder — 2294, 2 серебряных медали (в 2007 и 2008 гг.) международной олимпиаде по информатике.
• Сергей Рогуленко — рейтинг Codeforces — 2601, рейтинг TopCoder — 2926, прошел в полуфинал TopCoder Open 2011, финал Google Code Jam 2010, завоевал золотую (2008) и серебряную (2009) медали на международной олимпиаде по информатике.

Впечатляющие командные и личные достижения выдвигают эту команду в список фаворитов в любом соревновании по программированию. Я абсолютно уверен, что они заработают медаль и их шанс на золото не меньше 50%. Что вы думаете о Moscow SU ST?

Не забудьте, всего через пол часа, в 18:00 по Москве начнется второй раунд GCJ

Вот и состоялся отбор к Challenge 24, и опять можно искать попутчиков :)

На этот раз это может заинтересовать тех, кто из Будапешта поедет в Екатеринбург на чемпионат Урала.

Предлагается следующая часть пути:

• 29 апреля, 19:00, LH 1341 BUD — FRA
• 29-30 апреля, Hilton Mainz
• 30 апреля, 19:15, LH 1480 FRA — SVX

Соответственно, 30 апреля можно погулять по Майнцу/Франкфурту

29 и 30 можно будет поужинать в бизнес залах (самого по себе этого может не хватить, но с учетом питания на борту можно пережить), завтрак 30го будет в гостинице. К сожалению, цены на этот маршрут из Петербурга/Москвы выросли по сравнению с тем, когда я его брал (тогда было 15к, сейчас 20 с вылетом 26го числа), но вдруг кому-нибудь подойдет? Стоимость отеля — 93 евро. Так как внутри России сейчас перелеты в одну сторону стоят половину раундтрипа, то назад с чемпионата Урала можно купить отдельный билет

cerealguy может рассказать, не занудно ли со мной путешествовать
