AtCoder Heuristic Contest (AHC) is a series of programming contests 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, roughly alternately about once a month.

This contest is one of the qualifying contests for AtCoder World Tour Finals 2025 to crown the world champion of AtCoder players. Please refer to this post for more details.

After the contest ends, all participants can post their approach on the Editorial tab. Please share your approach.

AHC has a new rating system that is different from the existing ABC/ARC/AGC rating system. Unlike the ABC/ARC/AGC ratings, AHC rating system we use is monotonically non-decreasing, which values the best performance rather than the average performance. Please feel free to participate.
