We will restructure the contests.

• The admin of AWTF will be maroonrk. (no change)
• The admin of AGC will be maroonrk. (no change)
• The admin of ARC will be changed from maroonrk to snuke.
• The admin of ABC will be snuke. (no change)

Frequency of contests

• We will hold AWTF once per year.
• From August 2024 to December 2024, we will hold AGC once per month. The frequency of AGC in 2025 hasn't been decided yet.
• We will hold ARC once or twice per month. At least 20 per year.
• We will hold ABC almost every week.

Rated ranges (from AGC067)

• We will raise the lower bound of the rated range of AGC to 2000. (no upper bound)
• We will raise the lower bound of the rated range of ARC to 1200. (The upper bound will remain 2799)
• The rated range of ABC will be 0-1999. (no change)

The difficulties and the point values of ARC (From September 2024 / ARC 184)

• The problems will be mainly adjusted for yellows and oranges.
• If we predict that a problem will be solved by about half of the participants around rating 2000, we will usually assign 600 points to the problem (sometimes we may slightly adjust it for various reasons). Similarly, 2400 — 800, 2800 — 1000.
• We will mainly use problems with 600 points or lower for A/B, problems between 600-1000 points for C/D/E, and problems with 1000 points or higher for F.
• The difficulty of problems A/B/C/D will be similar to recent ARCs. E/F (especially E) will be easier.

We will hold ALGO ARTIS Programming Contest 2024 Summer（AtCoder Heuristic Contest 035）.

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.
