Добрый вечер, Codeforces.
Сегодня в тренировки добавлены первые пять контестов из известной серии Andrew Stankevich Contest. Они полностью доступны для прорешивания и вирутального участия.
По моему опыту участия в Andrew Stankevich Contest'ах я могу сказать, что эти контесты всегда подготовлены качественно, состоят из интересных задач и в них всегда весело и интересно участвовать.
Как говорится, good luck and have fun.
P.S. Все контесты доступны в группе Контесты Андрея Станкевича

Я очень рад, что мои контесты появляются на тренировках Codeforces.
Спасибо за высокую оценку, хотя баги или слабые тесты там, конечно, к сожалению, встречаются.

Good
Where can we find more of his contest? I personally will appreciate anyone who show me the way !
There are some at ZOJ: http://acm.zju.edu.cn/onlinejudge/searchProblem.do?contestId=1&titlefrom=0&authorfrom=0&sourcefrom=0&query=andrew
first problem : Chinese Girls' Amusement
WTL ?
Yes,it's the first problem of Andrew Stankevich Contest 1.
We will add more Andrew Stankevich Contests soon.
thank you!
А почему 3 контест длится 5:30?
Потому что в петрозаводске он длился 5:30.
Очень хочется порешать, но вот блин)
Вот блин
Условия задач доступны только на англиском?
Да.
Вот бы сюда еще старых Петрозаводсков залили!
I think there are some bug in tests of the first contest. It's my submission on problem D of this contest: 3768052
at least for the first test it's ok, isn't it?
You forgot to read from files. You can find input/output files names in the statements and here http://mirror.codeforces.com/gym/100199 near the problem name.
aha, ok , thanks
I like Andrew Stankevich Contests! Look forward for more!
Is there any chance that Petr Mitrichev contests from Petrozavodsk Training Camp could also appear? I have seen some at SGU, but I think not all of them.
It would be great if we could view others code in gym, at least after participating in gym.
Are there any editorials available for Andrew Stankevich Contest? Thanks for adding them in gym by the way.
there are editorials, but all of them were shot on a camera and distributed among participants. most of them in russian.
Actually you can see others' code after you become yellow and apply coach mode. So it is kind of stimulus to get higher rating ;)
Do anyone tell me how to apply coach mode? Thanks.
Go to gym, and in the bottom of the column on the right side of the screen you can see the button "Enable coach mode".
I can't find such button :(. Are you sure that it's available for yellow coders?
Quote from here: http://mirror.codeforces.com/blog/entry/6615?locale=en
"Now not only the red coders can become coaches. The coders with a yellow handle are now accepted as well, provided that they have taken part in an official Codeforces round no earlier than 6 months ago and have taken part in at least 30 rated Codeforces contests."
So, there are some extra restrictions as well. Sorry if I confused you with my previous comments.
Thanks.
В контесте "2003-2004 Летние Петрозаводские сборы, Andrew Stankevich Contest 3" в задаче F есть проблемы с кодировкой файлов ввода-вывода при сдаче на Java. После 20+ сабмитов оказалось, что файлы в кодировке KOI8_R, и надо вручную ее выставлять.
Спасибо. Добавим это объявление в тренировке.
В тестах действительно есть русские символы с кодами больше 127 и вероятно Java воспринимает их как utf-8.
Это похлеще, чем рантайм из-за стековерфлоу в DSU)
Есть где-нибудь разборы, тесты и авторские решения в открытом доступе?
Я не понял, как 2, 3 и 7 контест попали на одни сборы, а 4, 5 и 6 — на другие?
Кроме того, я не понял, как один человек может готовить 3 полноценных петрозаводских тура каждые полгода, но на этот вопрос вряд ли кто-то сможет ответить, кроме andrewzta.
Спасибо за указание на опечатку, поправил.
В посте всё по-старому.

. Просто результат закэшировался. Скоро все обновится.Спасибо.
Сидеть за компом и готовить.
В задаче С 18-го котеста какойто странный комментарий чекера: * ������ �⢥� * wrong probability log, expected: -1335.470584, found: -1870.087529
UPD: Извините, разобрался
I think that these contests is the biggest contribution to the gym so far... I personally want to thank Fefer_Ivan for uploading and updating these contests :)
Добавил 2007-2008 Летние Петрозаводские сборы, Andrew Stankevich Contest 27 (ASC 27).
Where to get the tutorials for these contests?
Hi, I made few submissions to ASC 1 but all of them stuck on 'In queue' status, after 30 minutes or so they turn to 'Running on test 1' and after some 30 minutes more to 'Judgement failed'.
The same here, 2 submissions are in the queue, seems codeforces is overloaded.
works now!
thanks very much,hope the last 45,46 contest will be on gym soon
Thank you very much for uploading these contests, I would give you many more upvotes than 1 if I could. I think this is the best possible source for team trainings. Quality of problems is very high, they are very interesting and well prepared :).
I had participated in the last two contests, I really like them.
The problems are really interesting but hard enough for my current level, I could solve only 1 problem in my both participations.
I think it could be very useful for many people if we can find ideas and solutions for this problems.
What about to open a post for each contest and make a semi-editorial together?
Hi, I am wondering how to submit code for these contests. I keep getting runtime error on test1. I believe something is wrong with the way I submit code since my code passes for other online judges with the same problem. I read from stdin and output to stdout.
You are submitting solution to ASC1, where you should use files for input and output (you can see proper file names at list of problems), but you are using standard input/output streams instead of files — and that is why you can't pass even 1st test.
I see. So I am supposed read from file and output to file as well? Thank you for the reply.
I just started doing the first contest,did 1st problem but couldn't do others as all other questions redirected to the problem statement of first problem.Can someone please look into this?
I'm really sorry,the 1 pdf contained all the problems.
I have submitted some solutions in ASC 1, and they are in queue for 20 minutes or so, and still not processed at the time of writing this. Also, in gym (in coach mode even), solutions submitted by other contest managers(shown on top of standings) are not view-able by double-clicking that cell. Is this some bug or feature?
Can somebody who has tried ASC-31 , help me out. I put up this post days ago, and no reply.
http://mirror.codeforces.com/blog/entry/19042
Does anyone have got an accept in ASC47-J? I've tried several approaches but still got trapped.
are there editorials available in russian or otherwise?
That's exactly what I also want.
Coach mode is not working for all of the ASCs. As soon as I open the ASC, coach mode automatically gets disabled.
Is it only me or someone else facing the same problem? MikeMirzayanov Can you please look into the problem?
I just tried. And yes, I faced the same things as you did.
Coach mode was automatically disabled. You may now enter the contest.
This message appears at the right-down corner, and coach mode is disabled as it reads.
Maybe it is because some tasks from ASC are used in acm.sgu.ru archive
UPD: The bug is still not fixed. :( It would really help if coach mode is enabled for these contests as they are a great resource to learn.
MikeMirzayanov Can you look into it?
It is not a bug at all, it is because these contests are in a group, and when you're in a group, there is no coach mode. Only the owner of the group can see the testcase data.
Can anyone provide a link to the editorials of these problems (any language would work owing to google translate) ?
Without editorials, I don't think any problems are worth trying. From where would I or anyone else who got stuck in any problem is going to get any help ??
Generally:
Try to make as many observations as possible;
If they were not enough to solve the problem, solve other problems/learn new topics/etc;
Repeat from 1 until you solve it.
You can find editorials to some of the contests here:
