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, alternately about once a month.

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.

We are looking forward to your participation!
