Reducing penalty for educational and Div3 rounds
By newbie_forever_at_cp, history, 4 years ago, In English

Hi Guys, I think the 10 minutes penalty for educational and div3 rounds is somewhat higher. In normal rounds the penalty for wrong submission is 50 points. If we take middle — high scoring problems such as C, D or E, then the amount of time it takes for the points to reduce by 50 is much less than 10 minutes. For eg, on most cases, the penalty for C problem is about 8 minutes, for D, its 6 minutes and for E its 5 minutes and for F its about 4 minutes. Hence if someone makes wrong submission and since the penalty is constant, it can be considered as making wrong submission on the highest scoring problem. So I think the penalty for wrong submission can be about 5 minutes as 1. It is the amount used in atcoder and 2. Just because when someone made a careless mistake or some error, they wont be penalised much than someone who did now know how to implement fast or who found the idea later and 3. Considering people (who are in rated bucket) rarely solve F, it does not make much difference switching penalty from 5 to 4 minutes. What do you guys think ? Pls share your thoughts.

Update : Including div3 rounds too.

You did not mention the div3 round, although its system is the same as the educational one. Maybe you say that to gain more rating in educational rounds? :)

I don't think , its a issue.

It's good to have penalty.otherwise some people will start submitting any randomized approaches and can make codeforces queue wait much longer.

I'm in for a smaller penalty.

Plot twist: that's mainly because I usually take multiple in-contest attempts to solve problems

I feel that the current penalty system is fine. Speed is not the only important factor, correctness is also important. Also regarding careless errors, it only happens often in your initial contests and you keep learning from your mistakes. Like I make a list of all careless errors I did in an contest and next time before submitting the code, I do a quick check to ensure I didn't commit any of the listed careless errors. This check usually doesn't take long and effectively reduces your careless errors, eventually to zero.

    like you make a code list or simply write down the error which can happen ??
