Updates on curtailing plagiarism

@shaily_adm @admin why my rating got decreased even I have solved the problem on my own, it is very demotivating moment for me, please look in the issue and get back my rating, why my rating get down , please check my profile my rating decreased START23C

But Utkarsh do publish those stream after contest ends so that sounds fair for us I think .

I think there is difference between a live stream and a recorded contest solution video. He Posts the recorded video after contest ends.

Okay sorry i did not knew that he post that after , i also checks youtube day after contest , and there were some comments saying thank you because of you i am again 3* so i just misundestood it

During Starters 27 (Rated for Div-2,3,4) till

During Today’s Starters , till last 15-18 minutes , I secured a rank of 362, and Then suddenly The submission for the fourth problem increased exponentially , and I finished with a rank above 1250 . The same thing happens since I started cp journey at Codechef. I don’t know what the hell the plagarism checker is doing here . If I sound rude , then there is nothing to apologize about ,these platform deserves it.

Where was this solution leaked? I’ve seen at least 10 accounts with this same solution.

why no action has been taken against him i am reporting second time on this but there are no actions on him please drop his ratings @admin @shaily_adm

Why do you think it is wrong?

Given N = 4, so maximum allowed operations are \left\lceil \frac{2\times N}{3}\right\rceil = \left\lceil \frac{8}{3}\right\rceil = 3.

In your case, the number of operations done is 3 which doesn’t exceed the maximum allowed.

@shaily_adm @admin @utkarsh_adm I beg your pardon for tagging you all but I have an earnest request… Can you please update us about plagiarism check stats in starters 24 and starters 25 the contests were held since almost a month and 20 days respectively and many cheaters are getting motivated to cheat in other contests too erstwhile. We were told that we will be updated about plagiarism checks atmost 10 days after the contest…
According to the notice can you please update us about the plagiarism checks in these two contests and please update the rank card as well

@anon89303627 PLPROCESS is quite an easy problem, It’s based on prefix sum. I think it’s quite possible for the solutions to match in easy problems.
