700-700-900-900, scary score distribution.

Problems are interesting :)

Why the downvoting speed got slow? I means, feel free to downvote me.

Does the score distribution still depend on Restructuring of contests?

The problem style gaps between ABC/ARC/AGC are getting larger and larger.

  • ABC = Classical Algorithms
  • ARC = Classical Tricks
  • AGC = Pure Ad-hoc Problems

As a retired participant, AGC is becoming impossible for me(I didn't solve anything in last AGC) but ARC is still comfortable for me.

Will 3000 become a new Western Wall after 2000?

Hello atcoder_official, ARC196 has been classified as "AGC Class" on the "Contest Archive" page until now (2025.4.11). Please fix this issue.

    So is ARC (Div. 1) recognized as AGC class officially now?

    Notes that the rated cap of ARC(Div.1) has changed from 2799 to 2999 since ARC196, but the rated cap of "ARC Class" has not been changed for now.
