A bug in Codeforces
By FFTotoro, history, 21 month(s) ago, In English

In CodeTON Round 4, problem H has a rating of *2900 on CF, but during the contest, only 3 people passed the problem. However, Problem G, which has 21 people passing, has a rating of *3200.

What's wrong with the problems?

The rating of a problem is based on the rating of the people who solved the problem in contest. Look at the rating and solves of rainboy.

    But this is unreasonable. Is there a good solution? Many times, this can lead to problems that don’t have the ratings they deserve, which can have a certain misleading effect on those who solve the tasks after the contest.
