Maybe Codeforces needs a more complete anti cheating system
By Ghosted, history, 2 years ago, In English

Now Codeforces has a relatively complete anti cheating system.

But there are still many ways to avoid it.

I have many examples to illustrate this, such as this, this and this.

So maybe Codeforces needs a more complete anti cheating system?

As the author of the 1st and 3rd post, I think so.

Although it can never be absolutely complete, we can make it relatively perfect.

There are, and will be a lot of loopholes in the system. I think designing an algo which compares the significant part of code can help.

    Have the LGMs implement that algorithm in a Div. 1 E and choose the best one lol

But some methods are always unavoidable. For example, you can't recognize everyone's face before every game to determine who it is.

    Although it is true, I mean to optimize as much as possible.

Isn't the current anticheat a modification of the winning solution of a heuristics contest that was held a few years ago? Maybe holding another heuristics contest might help.

    Do you have a link to the heuristics contest? I suppose it was on atcoder. Thank you!

What is the point of this blog? Just another person whining about cheaters without any suggestions or solutions on how to improve the situation. At least the blogs you linked helped to notify Mike about potential cheating cases. What does this blog do? Do you think it is not universally agreed that everyone wants a better anti-cheat system?

I think codefoces has many div 1 contests.

But I want more contests.

So maybe Codeforces needs more div 1 contests?

    Is this wrote to imply that the anti-cheat system works very rarely (correctly) xDD?
