We will hold 10th Asprova Programming Contest (AtCoder Heuristic Contest 023).

AtCoder Heuristic Contest (AHC) is a series of programming contests that will be held regularly on AtCoder. Unlike algorithm contests such as ABC/ARC/AGC, the goal is to create a better solution to a problem for which it is difficult to find the optimal solution. We will hold a long-term contest with a duration of more than a week and a short-term contest with a duration of less than a day, alternately about once a month.

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!
