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.

 » 9 months ago, # |   +9 how the difficulty level of a problem is determined Number of people solved the problem within what range of timeWhy the tags of a problem is not published just after the contestA 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.
