Problem difficulty and tag
Автор shanto_bangladesh, история, 3 года назад, По-английски

One of the feature of Codeforces I really wonder about is how the difficulty level of a problem is determined? Is it by any mathematical calculation, or manual estimation? Why the tags of a problem is not published just after the contest? Thanks for reading this blog. I will really appreciate your helps and insights.

how the difficulty level of a problem is determined

Number of people solved the problem within what range of time

Why the tags of a problem is not published just after the contest

A problem can be solved in number of ways.Suppose author did it greedily but some contestant did it with DP.Then the tags will be greedy & DP. Thats why it takes time to define the problem tags.

    But , not everyone has the tag edit access. Do there are special members/admins for those type of tasks?

      Div 1 coders (rating $$$\geq 1900$$$) have tag edit access provided that they have solved a "recently" added problem, such as a problem from a recent contest. Source
