• Rated range: All (Heuristic Rating)

Nihonbashi Half Marathon is a programming contest held by Recruit Co., Ltd.. This contest is rated for AHC rating. Unlike algorithm contests such as ABC/ARC/AGC, the goal of AtCoder Heuristic Contest (AHC) is to create a better solution to a problem for which it is difficult to find the optimal solution.

AHC uses a new rating system that is different from the existing ABC/ARC/AGC rating system. Unlike the ABC/ARC/AGC ratings, AHC rating does not decrease even if contest performance is poor. Please feel free to participate. You can check the current ranking here: https://atcoder.jp/ranking?contestType=heuristic

We are looking forward to your participation!
