admin said so in a post but he said need to do 4 problems or more 4th problem has like 90% plags too

99% plag it’s accuracy was 3 and suddenly elevated to 20 boom…

Wake up @admin do something about cheating in SnackDown. You are not even responding.

I was ranked around 400-ish today afternoon, and I checked now after struggling so long with EQBEAUTY and I found myself at above 2000!! Seriously? Everyone around the world got so hugely inspired and solved all the tough problems in just 3 to 4 hours? I think everyone knows what is going on and it is really frustrating. I had worked hours on BINFLIP and I’m sure there are others like me who could not qualify even after solving 4 problems. This is very disappointing. Please do something, CodeChef.

Are you sure your solution for 4th question count???
It is too much original I guess

lol the cheater is helping to catch cheaters… very good ma’am…

You don’t care enough about Snackdown

it’s 100% original ig :joy: :joy: :joy:

I care much buddy Did 3 also Did 4th but WA. Solutions are in front of me but I let them flew away

well i really didnt participate just because firstly i know i will not make it in top 1000 too and secondly this cheaters…:joy:

From 600 submission to 2500+ submission in just 3 hrs is so surprisiing. We know that unfair things happen everywhere and cheating also occurs in every contests of other sites but cheater’s count are scary in codechef .So, what makes any codechef different from other sites ?
The reasons are:
1 Little to no plag check
2 Codechef have more long contests,So, it gives cheater ample of time to modify their code to prevent plag.
3 Codechef doesnt not listen to demands of people.They just improve thieir UI andnothing else.

4.Codechef is an Indian site.Yes,It might anger my indian brother but it is true Indians cheats too much.
So, What can be the solutions?
Yes,No perfect solution can be found to prevents 100% plag but it can be reduced to greater extent.
1.More Number of Plag check.
2.Make plag check strong.
3.Long contest must be stopped.

4.Manual plag check.Yes,It may sound funny but codechef can select some individuals from each universities and pay them if they report certain number of plag solutions.
5.Some may say No.4 is economically not possible but codechef is already expending too much money in paying top 200 .so, why not stop that and use the money on No. 4.

6.Lets say that user are plagarised then what?
is decreasing the rating enough to stop them?
and the answer is No.
So punishment for plagiarised user should change.Punishment can be removal of stars(Just color for user no star), Different band of colors for 1 times plagged user and different for more than 1 times plagged users, low volatility of rating change, banning user from those types of contest etc.

I know admin will ignore all the suggestion but these are my views.
What are your views and suggestion??

As other sites use it, plagiarism checks exist - surely the CodeChef team can implement them?

A manual plag check is a good option, Codechef can ask for volunteers who are willing to check solutions, I believe many people will help CodeChef for manual check. Codechef can give a small amount of money or goodies in return. Many people will help without asking for money.

In Snackdown21 Round1A I solved 3 problems, and was ranked 5827.
In Snackdown21 Round1B I also solved 3 problems, and was ranked 115.
As I see it, so many cheaters qualified in Round1A that there were not many left to compete in Round1B.

Hello All !! I had a query regarding the plagarism checking on codechef . I wanted to know when do they check for plagarism , during the contest once we submit our code or after every contest when all submissions are made or do they check for all the contest at once during any time of the year.

Second doubt was in the contests there are easy questions too which have simple logic and short code so its quite obvious that there are high chances of getting similar codes . Does that comes under plagarism too? As recently in Snackdown online round B after the contest I saw many submissions which are exactly same as mine . So will codechef penalize me or consider my submission as plagarised? I didn’t cheated tho , still will i be punished?

Also I’m confused about when does CC suspends the account and when do they just give warning and decrease the rating along with giving a mark of plagarism on one’s account …i mean innocent ones who do not cheat can also get trap since their policies are quite confusing.
