PursuitOfHappiness's blog

By PursuitOfHappiness, 5 months ago, In English

In the last div2 that took place yesterday are full of cheaters. Around 200 people have same code in the first 300(proved in a blog) in problem D. Alas,nowadays leaderboard is full of cheaters. It's very alarming for codeforces. Mike should implement a **Report user's submission ** option to find out those cheaters(because some cheaters are so clever to fool the plagiarism detector). People here try hard and soul to solve 2-3 problems in 2.30 hours but these cheaters are ruining their hardwork. Unless there’s a severe punishment, soon code forces will lose it's ratings **CREDIBILITY ** .

One thing to mention :: people must recognise that the most brilliant programmers do practice in codeforces. Why not take the chance!!! Use them to invent new ideas to stop this mass cheating. They will have ideas that never gonna fail.MikeMirzayanov please give a chance to the best programmers from codeforces leaderboard to develop new plagiarism detector and develop new ideas.Another thing can be done.Arrange a contest from where the first 20 programmers from the leaderboard will do research on plagiarism.

At the end of the day rating doesn't really matter. We're all here to improve or compete. Remember, a cheater will never be number 1, since they're always waiting on someone else. They don't improve and hurt themselves the most

    But the main problem is:: Suppose yesterday’s D no problem. Good problem and almost hard problem. But as there are so many plagarised solution got AC, the rating of the problem will come down.Because the rating is defined by codeforces Algorithm. And when practicing you will find a 1700 rated worth problem 1400 rated

      but who really cares ? it's just a rating , i believe that most of us come to this website for improvement not for points or ranks ,ofcourse points and ranks are a great motivation , but at the end of the day , it isn't everything afterall.

its really bad to see nowadays many programmers are selling codes of contest and making codeforces a shamm

True! Being a beginner , sometimes I lose confidence when people cheat and submission of a particular problem increases which I am not able to solve! There should be something against plagiarism :(

    What I realised by now,codeforces authority not gonna do anything against cheating apart from plagiarism detector ignoring the tons of blogs against plagiarism...it's really frustrating

    what i thinkkk that codeforces should use some software that can block whole screen no other tab can be acceed and one can use there compiler to coder

      actually that isn't possible because we have to use text-editors/ide to code and submit the code .

i dont know to be honest what's useful of such a blog , like those cheaters don't care anyway, and about those who don't , u will enlighten them with the cheating , therefore they will cheat.

after all , Competitive programming is a sport and Codeforces is just a website that makes contests for that sport, but it isn't fully representative for it !.

And rating is just a number afterall.

Are there some demographic things at play here?

I see a lot of cheaters are Indians. Even LinkedIn is full of these posts.

What am I missing here ?

    If it has something with cheaters being Indian why don't you ask yourself? Aren't you an Indian as well?

    Ahh, but that's only because there are a lot of aspiring Indian programmers, not because they are more inclined to cheat.

If you mean 1546D - AquaMoon and Chess, it is just a problem with a conclusion...... If your conclusion is right, there won't be a huge difference in implementation like other data structure problem or something do.

I know cheating is really annoying and I hate it much too. But I believe most of the people solving problem D did it by themselves.

    Ya, That's true. logic was of just 3-4 lines. And, after that efficient calculation of nCr needed. And so I guess that would be same for all the submissions.

The guy hello_algorithm got plagarised again in the last contest.He has been plagarised in so many contest. He obsfucated his code but couldn’t avoid plagiarism detector.. Lol.Such a loser.He has been plagarised so many times.I wonder, is there any plan to ban this kind of guy from codeforces. But @mike did a great job.Though this famous cheater obsfucated his code but couldn’t avoid plagiarism. The plagarism checker detected it.Thanks to mike

    Even this guy got plagarised in 7 contests.. I don't know the upper bound of banning a id permanently for being plagarised so many times.How many contests result needs to be plagarised to be banned!! Just check his submission..It's look seriously nasty.So many skipped submissions altogether. Just uncheck the "" show unofficial "" tag and you will see how many of his submissions got skipped in last few days.Shameless IIts
