I've just discovered this question on Quora: What is the story behind your username at CodeForces?. I guess it'd be pretty interesting to hear stories from top participants. For instance, my handle's history is already described there.

This blog is dedicated to everyone who don't have Quora account, so you can share your histories and comments here.

I personally would love to hear stories from tourist, rng_58 and YuukaKazami from current top-10.

Hi everyone!

I am pleased to announce that Codeforces Round #304 (Div.2), of which I am the author, will take place today. This will be my first round, so I hope that it will be cool and interesting. Traditionally Div.1 participants can take part out of the competition.

I want to thank znirzej, Dakurels and Zlobober for help with preparing the problems, thank Delinur for translating the problems, and thank to MikeMirzayanov and all who created polygon for this great system.

I wish you all good luck!

UPD Scoring will be 500-1000-1250-1500-2250.

Привет!

Совсем скоро будет дан старт Финалу чемпионата мира по программированию ACM-ICPC.

Напомним, что своими корнями чемпионат уходит в 1970-й год, когда в США в штате Техас было проведено соревнование силами Alpha Chapter организации UPE (которая до сих пор участвует в проведении финалов). С 1977 соревнования имеют многоуровневую систему отбора и заканчиваются финалом. С 1989-го года организацию и координирование ICPC взял на себя Бэйлорский университет, а соревнование стало включать многочисленные региональные отборы, проводимые другими университетами.

В прошлом сезоне в чемпионате приняли участие 38160 студентов из 2534 университетов 101 страны 6 континентов земного шара!

В этом году в финале в Марракеше встретятся 128 лучших команд мира. Следите за финалом этого года с 12:00. Непосредственно соревнование начнется в 13:00.

The last but not the least interesting team is ITMO University's team 1.

ITMO has most championship titles, 5, out of 19 finals they participated in. They've got 10 Gold medals total, 1 Silver and 1 Bronze.

This year team consist of 2 Bronze Medalist from 2014, Borys and Artem, and World Champion from 2013, Gennady. Team is on first place in OpenCup Standings, won numerous contest this year and universally regarded as favorite to win World Finals, are coached by Andrey Stankevich.

Gennady Korotkevich (TC: 3794, CF: 3407) is one of the most honored coders ever. ACM ICPC Champion in 2013, TCO Winner in 2014, GCJ Winner in 2014, IOI Gold Medalist for a whooping 6 years (2007-2012), that's in addition to SIlver (2006) and many more achievements like Facebook Hacker Cup wins.

Borys Minaiev (TC: 2760, CF: 2776) won Bronze in last year Finals, was TopCoder Open Semifinalist in 2014, Facebook Hacker Cup Finalsit in 2015 and got 3rd place in Kotlin Challenge in 2014.

Artem Vasilyev (TC: 2612, CF: 2545) got World Finals Bronze in 2014 and was KROK Finalist in 2013.

It would be really unlikely for ITMO not to win Gold Medals, I have their chances at 99%. I think their chances to win is about 75%.

This year my alma mater is represented by team Moscow SU Tapirs.

Moscow State University has a long history at World Finals. 19 appearences, 4 Gold medals (all of them — 2nd places), 1 Silver and 7 Bronzes. Moscow SU is also 2 times champions of Europe.

Tapirs team came 2nd last year in Yekaterinburg in intense battle with St. Petersburg State University. In NEERC 2014 they came second as well, while losing to ITMO University team only on penalty time. Moscow SU is currently 3rd in OpenCup standings with one stage win. They had bested ITMO team on 2 more stages. Anton Pankratiev is team coach.

Gleb Evstropov (TC: 2405, CF: GlebsHP 2622) got 3rd in this year Facebook Hacker Cup. He also won Silver medal in IOI 2010 and was Russian Code Cup finalist last year.

Victor Omelyanenko (TC: 2531, CF: TeaPot 2687) got 2nd place on ACM ICPC World Finals last year with Gleb and Mikhail.

Mikhail Pyaderkin (TC: 2428, CF: meshanya 2550) won IOI Gold in 2010 as well as placed 2nd in Vekua Cup personal contest in 2012.

This team got only stronger since last year. Their chance to win Gold are at least 80%, while they had shoy at Championship as well, with about 15% chance.

Last team to look at will be ITMO University team.

Today let’s talk about The University of Tokyo team !#$%&()*+-./:;<=>?@[]^_`{|}~. University of Tokyo has long history of World Finals participations, this would be 13th time. They won one Gold, one Silver and 2 Bronzes, and 2 members of this year team won Gold in 2013.

They won regional contests in Tokyo and Kuala Lumpur, only team in Asia this year with such achievement. Team is currently on 17th place in OpenCup standings, although they skipped several stages and not always had optimal line-up. Tomoyuki Kaneko coaching them.

Kensuke Imanishi (TC: 2625, CF: wrong 2298) won 2 Silver medals in IOI (2010 and 2011) and was GCJ Finalist in 2013, that's beside his Gold in ACM ICPC Finals.

Shogo Murai (TC: 3017, CF: semiexp 2507) has 3 IOI Golds (2010-2012) and target on TopCoder to boot.

Makoto Soejima (TC: 3468, CF: rng_58 2849) is really a legend. He is one of only 4 people to win both GCJ (2011) and TCO (2010, 2011) and currently is TopCoder admin. Beside that he has Silver in IOI (2008, 2009) and Gold in World Finals.

While this team has really strong line up it's results are inconsistent. I'd give them 70% for Gold and about 5% to win.

Tomorrow we will look at team from my alma mater, Moscow State University.

Second team to look at is University of Zagreb

Once again, this third appearance of Zagreb’s team at World Finals and both in 2008 and last year teams got Silver medals. Stjepan Glavina and Ivan Katanic both participated in 2014 Finals.

Team decisively won CERC 2014 with 10 solved problems to second place’s 8. They participated in 3 stages of OpenCup, not very successfully though, and with 15 points are currently in 73rd place. Team also finished 5th in elimination round of Deadline 24. Zagreb’s coach is Kresimir Malnar.

Stjepan Glavina (TC: 2620, CF: 2509) won Gold in IOI 2009 and Silver in 2010.

Ivan Katanic (TC: 2704, CF: 2613) also has 2 IOI medals — Gold in 2011 and Silver in 2010.

Gustav Matula (TC: 2179, CF: 2160) had got his IOI Gold in 2011.

This team as about on par with Lviv, so I predict about 60% chance to get Gold medals and 1% for win.

Check back tomorrow as we’d look at University of Tokyo team.

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!
