С помощью нескольких опытных и уважаемых членов сообщества (спасибо!) было сформулировано правило, разрешающее использовать сторонний код при выполнении определенных условий. Внимательно ознакомьтесь с текстом.

Следующий текст войдет как часть в обновленные правила соревнований. Ближайший контест будет проведен уже по обновленным правилам. Таким образом, есть около двух суток для уточнения деталей, если что-то непонятно.

Решения и генераторы могут содержать код, чьим автором являетесь не вы, только в двух случаях:

  1. этот код был написан и опубликован/распространен строго до начала раунда,
  2. этот код сгенерирован с помощью инструментов, которые были написаны и опубликованы/распространены строго до начала раунда.

Любое использование стороннего кода не должно нарушать лицензий или авторских прав третьих лиц. Помните, что даже выложенный в открытом доступе код не всегда является свободным! По требованию правообладателя код, нарушающий лицензию или авторские права, может быть признан нарушающим правила.

В случае внесения изменений в код из пунктов 1) и/или 2) все эти изменения должны быть сделаны исключительно лично вами.

В случае возникновения спорных ситуаций (сомнения по поводу времени публикации, подозрение на нарушение правила об отсутствии общения во время раунда, прочее) бремя доказательства соблюдения правил полностью ложится на участника.

В настоящее время единственным надежным способом доказательства соответсвии правилу является наличие публикации используемого кода в интернете и его присутствие в опубликованном виде в кэшах известных поисковых систем.

Например, этому правилу соответствует использование кода с сайта http://e-maxx.ru/ или из Wikipedia (если код был написан и опубликован/распространен строго до начала раунда). Соответствие правилам использования в этом случае легко проверяется с помощью кэшей поисковых систем. Аналогично, допустимо использование кода из книги/статьи, опубликованной до контеста. С другой стороны, использование внутрикомандных заготовок (например, для финала ACM-ICPC) недопустимо, если не существует надежного и объективного способа доказательства времени написания этого кода.

Это правило ни в коей мере не послабляет запрет на общение, обсуждения или какую-либо другую форму коммуникации между участниками на любые темы, имеющие отношения к задачам, во время раунда.

IMHO, такой способ почти всегда существует: ведь составлять prewritten code для финала ACM-ICPC удобнее всего командно, т.е. придётся использовать version control (и это скорее всего будет github). Так что история коммитов там — неплохое доказательство.

    В случае github или других известных сервисов да, вопросов нет.

    Оказалось, что времени коммита в github верить нельзя.

        pastebin/github самые простые и доступные варианты.

        Если не хочется код хранить в открытом доступе — копия на dropbox (хранит историю изменений за месяц). Возникает спорная ситуация — доступ по линку. Как вариант подойдёт крупный (известный) файлообменник с зашифрованными файлами. Возникает спорная ситуация — линк + пароль.

        Университетский svn подойдёт, если его веб-морда кэшируется поисковиками или archive.org.

        Как отметили ниже, timestamp от системы, которая администрируется вами или вашими коллегами, не может служить доказательством. Если контент индексируется поисковиками, то другое дело.

      Оказалось, что времени коммита в github верить нельзя.

      Как доказательство того, что верить нельзя. Вот рабочая схема подделки временного штампа:

      1. Меняете дату время на своем компе.
      2. Делаете локальные комиты.
      3. Делаете push на github / gitlab.

      Как результат на сервере вы можете получить абсолютно любые даты, даже даты из будущего.

Если я правильно понимаю, то я также могу найти чье-то решение/кусок решения или просто какой-то алгоритм из задачи, которая была дана на другом контесте на любом OJ, позволяющим сделать это с точки зрения лицензии, в том числе и codeforces, и сдать его?

В английской версии:

This rule doesn't loosen the rules about prohibiting of communication, discussion, or any other form of communication between the contestants on any topics about the problems during the round.

Как-то тавтологично выглядит.

Кстати, в GitHub (как и в большинстве видов VCS) время коммита несложно подделать. Время правок на Википедии тоже можно подделать, если вы там администратор или выше. Кеш поисковиков — не очень надёжное решение: к моменту разбирательства он может переиндексировать сайт, и доказательство пропадёт. Wayback Machine сохраняет старые версии, но индексирует достаточно редко. Как доказывать факт отсутствия общения, вообще непонятно.

    Женя, про GitHub расскажи подробнее. Понятно, что всякие локальные VCS ненадежны, а вот с сервисами не очевидно. Администраторов русскоязычной Википедии всего 92, мне кажется глупо идти на должностное преступление перед сообществом для сомнительного преимущества. Разбирательства в любом случае надо делать быстро — кажется, что поисковики реиндексируют не так быстро, чтобы были сложности.

      Git децентрализован. То есть я могу локально перевести часы куда угодно, сделать коммит (в локальную копию репозитория запишется изменённое время), а потом сделать push изменений на GitHub. В результате на нём будет сохранено произвольное время коммита. Я не знаю, хранит ли он время push или нет, но думаю, что это в общем случае бессмысленно.

        Егор и Женя, я не вникал в подробности работы github, но кажется что какая-то метаинформация в сервисе (дата-время) должна устанавливаться им самостоятельно. Давайте вы попробуете провернуть о чем писали выше и доказать с помощью github, что у вас там был документ с этим токеном d37ee9ca6267ec485a4783ceb9fb07d4d0afa8205c3fe756 (сгенерировал только что) до публикации моего комментария. При любом исходе это будет полезный эксперимент.

      В Git можно задать произвольное время коммита, в Subversion при наличии административного доступа его можно изменить. Общая мысль такая, что сервисы VCS не рассчитаны на использование для timestamping, а скорей наоборот, часто поддерживают функции, вроде импорта истории изменений, позволяющие задавать метки времени произвольно. Я бы больше доверял дате последнего изменения, скажем, в Google Docs. Если не хочется заливать туда весь код, можно записать только хеш (криптографический) от него. Можно даже создать в профиле Codeforces поле — хеш архива с кодом, чтобы не зависеть от всяких внешних сервисов.

Sorry if this is already answered in the text above, I'm not quite sure.

In a number of contest websites (including TopCoder and here on Codeforces), after a contest finishes, the source code for each submission is viewable by any member. Is this considered "published/distributed" code? (e.g. does this rule mean that all contestants can use past submissions of every other contestant?)

    Ключевые слова: "не имею права использовать чей-то код". Если ты такой код хоть 100 раз перепечатаешь, ты не получишь право его использовать (разумеется, если автор не указал в лицензии "перепечатайте код 100 раз, и он ваш").

Конкретный вопрос по использованию сторонних библиотек JavaScript. За jQuery спрашивать не буду, а вот на underscore.js интересно. Код библиотеки однозначно написан и опубликован до начала раунда и его использование как свободно-распространяемой библиотеки не вызывает вопроса. То есть я могу включить код библиотеки underscore в начала своего скрипта и мне ничего не будет?

    Очевидно, ничего.

    Однако, во-первых, библиотека Underscore распространется по лицензии MIT, которую следует соблюдать (в частности, не стоит копировать код и не копировать лицензию), во-вторых, вроде бы существует какое-то ограничение на размер отсылаемого кода.

Currently, the only reliable proof is the presence of code on the Internet and the presence of the used edition in the cache of well-known search engines.

Do I understand it right? Presence in cache of well-known search engines is mandatory for a proof to be considered reliable, isn't it?

What about the Wayback Machine (archive.org)?
Is it reliable enough?

          Downvoting with explanation is supportive and responsible
          (but yes, it is risky because your explanation comment can be downvoted itself).

          Downvoting with no useful explanation is just harming another person's contribution score without taking any responsibility or risks for that.

          That's why I call the latter behaviour coward and irresponsible.

            Okay so this is just arguing for the sake of it, but...

            1. Contribution score doesn't matter.
            2. "Coward" means one is afraid to take a risk. While indeed downvoting doesn't take any risks, people don't downvote comments because they are afraid of taking risks. People downvote comments because they are wrong, offensive or just plain garbage.

              Then why not to explain the reason of downvoting in a couple of words?

              Otherwise, how an author (of a downvoted message) is expected to learn what exactly is "wrong, offensive or [inappropriate]" about his/her comments and why it is considered wrong?

              (I think the practice of explained downvotes would significantly decrease the total number of "wrong, offensive or just plain garbage" comments because their authors had a chance to learn community rules faster: what is considered bad in this specific community, and why.)

              I understand that there are obvious cases (such as offensive comments) where explanation is not needed. But in this specific case it was not obvious (and it is still not obvious). Not for me, at least.

              Agree.

              And this actually does not cover ones who are not afraid to take the risks but just too lazy busy to explain themselves.
              On the other hand, I would not call such behaviour responsible (giving to the community is important, just taking from it is not good).

          (A bit more detailed answer. Back to the original issue.)

          A bad thing -- as I see it -- is that I was left alone with my downvoted comment and without important information.

          Specifically, I still have no idea why the original comment was downvoted.

          I do not have information, neither about what exactly was bad about that my comment, nor about who downvoted it (so that I could ask them personally).

          How should I learn from my mistakes in such situation if I do not understand what exactly my mistake was?

          In my opinion, sharing information which allows other members to learn is a crucial thing for a community.

People downvote maybe just to feel better and harm others, idk.I see many guys explaining their solution to problems that are not in editorial and require some advanced knowldge getting downvoted. That's the way things are, nothing to do about that. MAYBE I WILL GET DOWNVOTED TOO,tring to keep your side.

Both of the submissions were made my me for Question C, and i was thinking that the earlier one would be ignored as we have in any normal Round.

I request the community to help me out here as I don't know whom should I contact about this.

      To sir MikeMirzayanov, !!MISCoincide Codeforces Round #685 (Div. 2) https://codeforces.com/contest/1451

      In the name of almighty Allah who has the knowledge of seen and unseen . The message has sent to me about the solution of 99130524 for the problem 1451A . It said that a significantly coincides with solutions Nushrat_Jahan/99125543 , Maskur_ICT_MBSTU/99130524 is really so pathetic to me. Really Codeforces is the best platform for competitive programmers . I really do appreciate the system of judging and the approaches followed by codeforces . But the issue is that whatever we have all is the virtual machine . It’s an abstract thing . The way the system judge my code and found that my code is coincide with the code of Nushrat_Jahan/99125543 is for the issue that we have followed the same approaches . And it is undoubtedly true that I had not taken any help from google or communicating with Nushrat_Jahan/99125543 . I’m not familiar with Nushrat_Jahan/99125543 in virtual world or real world . So how can I copy Nushrat_Jahan/99125543 ‘s code . And the code was written in my codeblocks ide and was not shared with others. The way I and Nushrat_Jahan/99125543 had thought is not any intentional case . The logic comes from divine source . So if my thinking is same with others “is it wrong to write that code” . How can I know that the other person’s thinking is the same as mine ? Can you? No we haven’t that power . Finally I strongly opposed about the issue of coincide that the code was thought , solved and written by my own effort and also added that “ is it justice to skipped my problemB for the problemA “ Please recheck my code and make sure that the code was not coincide . It was my work . Thank you Codeforces and to you.

Hello Everyone, This morning I got a message from system that my submission for 918A khyati.agarwalss/34669006 during the Contest, has been found significantly similar to someone else's solution and a warning that my account may get blocked due to this. I wrote a very basic solution for that problem which was a short cut method, and it may possibly match with someone else's because no particular algorithm was applied in it and I used a saved syntax of jdoodle/c++. I request the community to help me out and make my solutions valid for the round 918 Div.2.

Please clarify the message that is sent to users. I don't know where to "write a comment to post about the round with all the details". If this is the right place, please re-evaluate my solution for contest 919. The system claims neutron-byte/34741180 is similar to czommerfelds/34745389. The solution is very simple so it is no surprise it would be similar. Also the first result on Google for "c++ sum of digits" yields the same function http://www.sanfoundry.com/cpp-program-display-sum-of-digits/. Thank you. Best, Christian

I received a message from CodeForces after round# 464 that my solutions for A,B and D have been plagiarised. The solution to D was DSU and code was available on HackerEarth link for D's code. Problems A and B were trivial, I think because of similar template the solutions have been caught. The template which I use is really common. The codes for A and B were of <10 lines and hence the similarity. Kindly look into the matter.The variable names which I use are really common amongst the programmers hence the similarity.

This is a brute force solution and there was a similar problem "Palindromic Supersequence". Also if the members of the same team gets the same solution I recommend giving time to the involved participants to make changes in their code as the solutions are constructed while sitting in the same room. This type of instance is highly regretted and will be careful for the next time.

Sorry, for being irresponsible. Yesterday in the "Educational Codeforces Round 42 (Rated for Div. 2)" I unintentionally used ideone as my system compiler wasn't working fine.I forgot to change the visiblity settings of ideone and someone intentionally misused my code. I would take care in future to not repeat this. my ideone code link during the contest is https://ideone.com/8vObjQ I saw the users profile with whom my code coincided(as said by you) ,his every solutions had been skipped which means he has a habit of copying. So i am innocent.

FOR EDUCATIONAL ROUND: 42 ( The latest one)

I received a mail about violating the rules of the contest, by copying the code. But I have conclusive evidence that I had taken the code from a AC code of another problem, 908F. If u want I can link the solution here, from which I took the code. However, it was present BEFORE this contest began. So I am not sure how this can be a violation of the rules. It's the setters fault that the problem was exactly the same.

My solution : http://codeforces.com/contest/962/submission/37168611 The code I took it from: http://codeforces.com/contest/908/submission/33800403

I too had a AC code to this problem:908F (http://codeforces.com/contest/908/submission/33824171) But that got some error, so I decided to take another code.

Please nullify the claim that I collaborated with someone else during the contest. It is pure coincidence that they took the same code.

Sorry for being irresponsible. In 'Codeforces Round #498 (Div. 3)', I used Ideone Online Compiler and forgot to change the default settings to private access. My ideone link during the contest is — https://ideone.com/BcjYgN. My code was used by someone else intentionally. I also saw the user's profile and observed that his submissions in past few contests have also been skipped. Maybe he had copied other user's solutions as well. Also I submitted my solution for the problem 1006D before this person. I am innocent and would take care in future not to use ideone during live contest.

    As you pasted, "unintentional leakage is also a violation", so you aren't innocent according to the rules. Pay more attention next time and move on.

Attention!

Your solution 40945148 for the problem 1013A significantly coincides with solutions **/40942768, **/40945148. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.com/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties.

I created account cn18 just to see and access API of codeforces. But when the comp started I by mistakenly submitted by code using cn18 id instead of my id. On realizing it I shut down my id there was no way to remove the code from cn18 id. Sorry, it was my mistake. Moreover, you can see how easy the solution was. I didn't do it purposely.

Solution 41051114 for the problem 1015C significantly coincides with solutions saxapo/41050928, 177shivam/41051114 since both the solution is same because it is written by me only. Sir since website is not working smoothly so i have to submit my answer as fast as possible so i can do B problem, so i have submitted it by another account but as soon as my 177shivam profile opens after some time than I submitted my own solution in my own account. Sorry for rule violation if a rule is violated and I was not familiar about this rule and now onwards it will not happen again.[user:177shivam][user:177shivam]

Hi Codeforces, yesterday i participated on Codeforces Round #503 and I managed to solve 3 problems.

Unfortunately this morning when I woke up to check the results, i received a message from the system saying that this two submission 41488655 and 41489033 are the same.

I cannot deny that they look exactly alike. But when i did the third problem my IDE (CodeBlocks crushed) and i was forced to use ideone.com (link to ideone code, made 15 hours ago) to compile my code, and probably the other guy took it from there because I don't have any idea how else could he got my code. I didn't know that others can view your solution when using ideone. :( I will never use ideone again during a contest.

Now i don't have any idea how to prove myself as being the author of the problem. But i will try at least, maybe i can still keep my codeforces account. You can see for sure that the other guy copy pasted the problem. The first two problems do not match mine at all. And when you look at his submissions you can see a lot of them for problem C and the difference between last two 41488455 and 41488655 is just one minute and I don't see any way he could come with a totally different solution in just one minute. The submission are completely different.

And if i was using two accounts, do you think I would have wasted time coding two different solutions for the first two problems? Also you can see that the other guy, does this not for the first time, at the last Educational round he did the same. (image proving this).

I hope this can prove my point, have a nice day and thank you for reading, at least I shared my anger with you.

[Edit] Now it seems that i don't have access to any submissions. :(

But suddenly today i got a message from your team that one of my solution match with some other user. Actually yesterday i used ideone with the privacy public by mistake. I think my solution might be leaked due to that problem. Sir/Madam, I am wrongly penalized as that was done unintentionally but i make you sure that mistake will not be done next time.

I found the problem in the compilation environment three minutes before the competition, so I used ideone. I was not used to ideone, compiled without turning off the searchable option, and was excluded this round. I am aware of my mistake. Sorry.  This may be insufficient evidence, but since most of my code so far has been written on the same template, I can show that the header, type definition, and variable declaration are exactly the same.

My source code of last round http://codeforces.com/contest/1025/submission/41833456 http://codeforces.com/contest/1023/submission/41750569

Copied source code http://codeforces.com/contest/1028/submission/42159376 http://codeforces.com/contest/1028/submission/42159445 http://codeforces.com/contest/1028/submission/42179991 http://codeforces.com/contest/1028/submission/42163628

I will pay great attention to the use of ideone in the future. May I ask you for a favor in this round?

Hi,

This is regarding Round 511 Div 2. My submission, abhisheksince97/43197368 has been flagged for coinciding with solutions vbbvaddd79506/43196786, priyasen54/43197486, fibo1/43201480, gennadykorotkevichaz/43202067, cpp19/43202087, milanmas/43202887.

I can prove that the solution is mine and the others have copied it. You can open all my recent past submissions, I have used the same template for .cpp file as I have done in this one. The rest have clearly copied.

Also, the solution that I have written is available on geeksforgeeks (https://www.geeksforgeeks.org/largest-subsequence-gcd-greater-1/). This could also be the reason for the match.

I was really foolish and naive to have tested my code on ideone. Please verify that I am the true author of this solution and please let this contest be rated for me as I put a lot of effort into it. I have never done such a mistake before and wont do it ever again.

But there is a valid reason .We both are from the same college and we are friends.Actually ,yesterday my laptop was not working.So i just go to my friends room lalitha.There we both have solved the sum and just then ,as it is my friends laptop,she submitted first .There is also another problemin my college.Suddenly the internet stops working in sometimes.Keeping in mind that reason,i have logged out my friend account on her laptop and i have just copied the same code into my editor in my account and i submitted it as we have both solved the problem.And i can change the variables names and i can submit it,but i thought if the net stopped working ,then what i have to do? Moreover ,there are exams are going on.So we have to study for the exams .These are the reasons for that mistake. This is the first time and last time. Next time onwards ,i will not repeat this mistake. I will do on my own in my laptop.

Thank you

Dear Sir/Ma'am, My solution 49711461 for the problem 1114B was completely and solely coded by me. I've used ideone to run and test my code on some sample test cases. This solution has coincided with solution ivaan/49710829. I am completely innocent. This user handle is a total strange to me. Therefore, I request you to consider my request and look into the matter.

I received a message from codeforces system today regarding the similarity of my code with 2 other users. The reason for this may be that I was using ideone in public mode by mistake. Here are the links of my solution: https://ideone.com/s2sHpB https://ideone.com/Yax8pe https://ideone.com/9qbTAo

The only proof I can give you that I have not copied is that I coded the solution for problem for D1 and used the very same solution for D2 and got runtime error. The reason for that was the difference in array size I was using. In problem D1 I defined my array size=100 #define N 100 in my code. I submitted the very same code for problem D2 and got runtime error on a test case. I figured it out very soon due to large size constraints which the problem statement had and changed my array size by, #define N 200005

Had it been a copied code from somewhere I must have got accepted answer in first go or it would have taken me a significant amount of time to realize the error in the code.

The next proof I have is that you can see my coding style which is consistent across problems. I declare global variables with long long data type, use macros for defining array_size, #define N 200005

Request you to please give back my rating. It took me a lot of hard work and motivation to get a rank among top 1000 after such a long time.

In round 541, the problem A had a trivial one line solution, which I had not shared with anyone. There are people bound to have similar code when the solution is only one line. There has been a false positive on plagiarism. I do not have any contact with the people that have the same answer, nor have I posted the solution anywhere else. Please remove the penalties that have been placed on me.

Hello, I received this message today — "Your solution 50439498 for the problem 1130A significantly coincides with solutions lannister07/50438986, rajat_dhoot/50439498, fake12345/50446224." I did not copy anyone's code. Following are the evidences to support my stance — - You could look at any of my submission and coding style/pattern, they are same. - But the other two id's that you have provided seemed to be fake id's used for submitting and checking the solution. If you visit there other solution, you could easily make out that the entire coding style and template are different for every submission that they have made. All of their submissions are copied. So, I request the admin to ban their id. Yes, I did use ideone.com for testing my solution. I was unaware that my code could be hacked from there. Sorry for that. Though, I still wonder how they were able to hack it but anyways thanks for letting me know about such a scenario. I ensure that the mistake would not happen again. Since, I am relatively new to such contest, it would be encouraging if you could revoke penalties that have been imposed. Thanks :)

In Round 61, Question F has a simple digital DP. I didn't share it with anyone, and the question is very similar to the 1260 on BZOJ. When the title is the original question, people will necessarily have similar code. Plagiarism has a false positive. I didn't contact anyone with the same answer, nor did I publish a solution anywhere else. Please remove the penalty for me.

Attention!

Your solution 50854676 for the problem 1132B significantly coincides with solutions adipro/50848546, apg_/50854676. Such a coincidence is a clear rules violation. Note that unintentional leakage is also a violation. For example, do not use ideone.com with the default settings (public access to your code). If you have conclusive evidence that a coincidence has occurred due to the use of a common source published before the competition, write a comment to post about the round with all the details. More information can be found at http://codeforces.com/blog/entry/8790. Such violation of the rules may be the reason for blocking your account or other penalties.

This is not a coincidence. Sato07 is my brother's account I made and will be participating in the contest with it only. I logged out automatically after submission due to server problem I guess. I don't how I logged in the account of IBatJ. I did not know that I the account I selected was IBatJ and not Sato07. And after that it should that I did not submit the code so I resubmitted the same code.

Please don't ban me. And give my ratings back.

The game is nearing the end, my friend shared his code, I don't believe in such a long code, so I submitted the code, I forgot that the game is not over, even if there is one minute left. I forgot the spirit of the game and violated the rules of the game. The talks said that I might be titled. This is the last thing I want. I want to continue to participate in the competition.
