We will hold THIRD PROGRAMMING CONTEST 2023(AtCoder Heuristic Contest 030).

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.

We are looking forward to your participation!

We will host AtCoder World Tour Finals 2025 to crown the world champion of AtCoder players!

AWTF2025 will invite a total of 24 contestants, 12 in the Algorithm division and 12 in the Heuristic division, to the finals to be held in Tokyo, Japan.

The finalists will be determined based on the results of AtCoder's contests during the year 2024. The schedule for the finals has not yet been finalized, but will be announced by the mid-2024.

The method for determining the finalists is as follows.

Algorithm Division

The finalists will be determined based on the results of AtCoder Grand Contest. If you get the top 30 places in AGCs, you will get GP30 scores. The top 12 with the highest total GP30 scores will be invited to the finals.

Heuristic Division

The finalists will be determined based on the results of AtCoder Heuristic Contest. If you get the top 30 places in AHCs, you will get GP30 scores. The top 12 with the highest total GP30 scores will be invited to the finals.

We will hold RECRUIT Nihonbashi Half Marathon 2024 Winter(AtCoder Heuristic Contest 029).

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. You can check the current ranking here: https://atcoder.jp/ranking?contestType=heuristic

After the contest ends, you can share your approach on the Editorial tab. Please feel free to use it.
