codingkshatriya's blog

By codingkshatriya, history, 4 weeks ago, In English

I came across this site (https://kenkoooo.com/atcoder/#/table/ ) that quantifies the difficulty of atcoder problems,but I was wondering how it would relate to CF difficulty, Any inputs would be great

There are already 3 blogs asking the same thing
https://codeforces.com/blog/entry/81704
https://codeforces.com/blog/entry/80461
https://codeforces.com/blog/entry/83546

Do a google search before making a new blog.

    I don't understand why people find asking on blogs easier than just googling first.

    When I need to know something I prefer to find answers via Google, I don't have the patience to wait days(or hours) for someone to respond with an unsatisfactory answer.

    Read the blogs first before quoting them. I have read all 3 blogs and none of them are actually helpful.

    First blog has an answer that proposes an equivalence graph among various Oj's, but it is percentile rating distribution in an OJ and not about problem rating equivalence.

    Second has only 2 answers, and neither are related to my current question,the second answer says why atcoder seems harder

    And third blog has answers discussing about difference in their CF and atcoder rating.

    And I didn't want to simply revive the old blogs,because the ques was fuzzy and blog desc had nothing to do with the ques asked.

      The blogs I mentioned are quite related to your question.
      If the question is not answered satisfactorily in those three blogs, you could just comment on the existing blogs, right?
      Moreover, if that question is not answered there, how can you expect that it will be answered here?

I would say Codeforces = AtCoder + 300. The nature of the problems on both the platforms is quite different though.

    1300 in Atcoder, going to be 1900+ in codeforces and I have participated 8 contests in Atcoder.
    This is more than 300 I think

      I agree, that has happened a lot of times. Shouldn't be more than a 300-600 difference though. (I am 1430 on AtCoder at the moment, I should probably be CM by now xD)

    Shouldnt it be scaled by some logarithm function instead of constant :v

My experience: I felt atleast 1200 difference.

In this blog E869120 gives about 1500+ difference.

Where does it say Atcoder's rating for each problem? Is it just the point values for the questions?

The toughest problem ( as of now ) which I can upsolve in Codeforces after giving much time are rated 2600. The toughest problem ( as of now ) which I can upsolve in Atcoder after giving much time are rated around 2900( I use atocder kenkoooo to get rating ).

so I think Codeforces(2600R) is approximately equal to Atcoder(2900R).

The Problems beyond the above mentioned rating in respective site are beyond my scope of understanding( As of now xd )
