unbelievable's blog

By unbelievable, history, 4 years ago, translation, In English

I think this thing bother not only me, but huge part of codeforces community. When I press top button, I expect to see some useful hits, new algos, editorals, invitations to different contests. However, I see 246376243 posts from unrated people who complain about cheating in educational rounds. Personaly, I dont care about this cheating at all. If you get +5, not +6 because of someone cheated its not the end of the world. And cheaters don`t ussualy get first or second place in the contest so they wont be given any material things from sponsors etc. If CP for you is only about rating on website its really bad. For me its a great possibility to practice and solve interesting problems, so cheaters dont interfere me.

I dont know, why so many people try to find cheeaters in every round andhow do they do this, but maybe codeforces should just implement report mechanism? This will release top section from "detectives" and cheaters still will be punished.

I am open to a discussion in comments, please share your thoughts.

Yeah, a lot of people bring up the fact that they're putting in hard work to do good while the cheaters are just cheating but I don't think this is valid. Rather than using rating as a measure of someone's skill, a person should look at how difficult of problems they can solve now and compare it to the past. Posting a billion blogs about cheating won't make cheating disappear. The plagiarism checker seems to be good and I don't really think Codeforces can take too many other measures to reduce cheating. People should just suck it up and focus on their skills and not rating and just have fun.

      By looking at the difficulty that's assigned to the problem.

        And that difficulty is assigned using the rating of the people who solve it during contest. "Rating" matters in these kind of things.

          I don't think so. If I solve a 1800 problem, can it be 1100? Or, If I solve a 800 problem, can it be 1100?

            If 100s of 1100 rated people solve a 1800 difficulty problem after copying from telegram... it will be rated lower than 1800 after contest ends.

                I think you are confused how problems are assigned rating... Not solving implies it was harder than your level...
                Wait ,think of it this way..

                X rated problem was solved by many 1100 rated cheaters .. so it implies rating of X must be less 1100.

                And second case... Y rated problem remained unsolved by many 2100+ rated people..So it implies Y must be more than 2100,

                If you solve a 800 difficulty problem, that's fine because you were supposed to solve it anyway.

                  Hmm, I think if X rated problem was solved by many 1500 rated cheaters... rating of X must not be less than 1500.

                  If you solve a 800 difficulty problem, that's fine because you were supposed to solve it anyway.

                  I don't know why you're not supposed to solve Pairs which is rated 1900.

                  You could've just said that you've never heard of statistics.

                  the ratings are a mere indication denoting that this person would/would-not be able to solve this problem with high probability.

                  just because you found one counter example doesn't contradict the claim.

                  You could've just said that you've never heard of statistics.

                  You should've shut your mouth before criticizing someone if they had ever heard of statistics.

                  the ratings are a mere indication denoting that this person would/would-not be able to solve this problem with high probability.

                  I'm not contradicting that but sometimes the problems' ratings are completely random. More like subjective.

                  just because you found one counter example doesn't contradict the claim.

                  I mean, If you know how statistics works, You should not ask me this.

                  P.S You're just some random ass idiot who is insecure about his identity and comment some bullshit. I dare you to comment from your real account, If you want someone's attention. hypocrite!

Like you I have never tried finding submissions which might have been plagiarized. Also, I too feel its such a waste of energy that we have to find them.

Do I think there should be no process to prevent such incidents? No, they absolutely need to be there or these things will just keep increasing, till it will be no fun to compete and we will feel I might as well have solved the problems under a 2 hour timer(we are far from there because such efforts are taken).

Yes its true that how we do it now where we constantly see every other post about cheaters is irritating.

A form to report cheaters is a good feature and most demanded every time blogs reporting cheaters become a nuisance. But, that too can increase a lot of manual work on the receiver's end i.e. sifting through reports and deciding manually in some cases. In practice, Codechef has a blog and an email ([email protected]) dedicated to reporting cheaters but it has done little to combat redundant blogs as you can see the list of blogs posted after the master blog to report cheating was published, this is even after warning everyone that any new topics on cheating will be closed and the author can be suspended.

      From my point of view, it is.
      On one side you have honest people who have worked hard for months hoping that they will pass the round and get an interview.
      On the other side you have dumbasses who don't even have the ability to recognize what language the code is written in and are looking to "beat the system" and become winners?

      Whether you are doing cp for job or for fun, doesn't matter. What gives you right to ruin it for others? Even if 1 deserving person misses the opportunity due to this, its still extremely unjust imo.

        From my point of view, it is.

        Agree. Cheaters should be banned from participating and polluting the atmosphere.

        On one side you have honest people

        But please don't bring honesty into this. Many people who don't cheat, don't cheat not because they are whitewashed and honest, but because they know it's not gonna help much in face-to-face interview. So they must practice for learning (excluding people who do it for fun and enjoy it). Most would willingly cheat in college sem exams because they know it's not important and being honest there isn't gonna help much (example). So I would say it's just about personal preference and convenience. But I agree that it is very very unfair to the people who are being honest, whether it's CF or college exams.

        What I just want to say that "not cheating in contests" does not imply being an honest person in general.

      Yes.

      why?

      It is against the rules.

      Hence nobody in Codeforces really cares about what you think of cheating. It is a no-no here.

    I can also defame your country by telling my personal experience with toxic Chinese people who use cheats in almost every competitive multiplayer game. It is to the point that you can't even play on Asia servers any more (talking about BattleField5, PUBG PC). You have to use VPN to play the game, and you are ready to pay 5$/month for premium hacks. Tell me now, what is more pathetic? People cheating because they think they might get a job (stupid indeed) or people cheating in a multiplayer game so that they can get a good Kill Death Ratio in a game? Also have come across many from your esteemed nation who use engines on chess.com. So let's not attack each other's country and try to find a solution instead of generalizing. Because we can do that too.

        Why are you sorry? They are clearly from India, nothing wrong to state that.

I have a perfect plan how to get rid of cheaters:

  1. Ban all Indians on all programming sites
  2. Their HRs can't use their CP ratings for hiring anymore
  3. They stop doing CP just to get job
  4. Unban them
  5. Only interested people remain, they will not cheat

    So now you are saying people have to give some prove of nationality to use codeforces. I don't think there is no other way to implement your PERFECT plan.

    If you are giving possible solutions to a problem, give some practical and non-racist solution.

      India is a nation comprising of various races genius. It isn't a single race called Indian. So no he is not a racist.

    +1!

    Ban Codeforces in India (Probably ban only contests, enable practice/upsolving). They have their own platform Codechef and a lot of tutorials on internet in hindi.

      Indians can influx atcoder as much as possible and I don't give a shit. Atcoder has no discussion system indians can not bother anyone.

        Alternatively, you can ignore the discussion forums in codeforces and treat it like atcoder- a website with no discussion forum. Problem Solved!

      Atleast India is better than your poor Country

      And we have our own CP platforms, so we wont be affected if this happens in any case.

    Unpopular opinion: Add "ratings are not a true approximation of skill" beside ratings of every CF user.

No matter what we say or do...there is possibly no way to prevent cheaters from cheating. Each time MOSS and plague detector are upgraded the cheaters find a new way out.

Few days back i saw 2 submissions exactly the same except for the part where one submission comprised of multiple call of a function which just incremented a value of a number by one. And the worst part is he did'nt even use a loop..

'twas something like this

int co=0;//global

and in a function

increment() {co++;co++;co++;co++;co++;co++;co++;co++;co++;co++;co++;co++;co++;co++;co++;co++; 200 times probably}

and this function was called throughout the main function.
