Sorry for the late announcement and unusual time. It was hard to find a good slot (some local marathon contest and SRM on Saturday, Open Cup on Sunday, sponsored ARC in the next week, TCO after that, etc.)

We hope to hold two more AGCs in this year (excluding this AGC), and guarantee at least one.

We will hold AtCoder Grand Contest 040. This contest counts for GP30 scores.

The point values will be 300 — 600 — 800 — 1100 — 1400 — 2200.

We are looking forward to your participation!

Has it changed since last year?

Now I can't run it for last year's tasks (Judge return code: 255)

It works fine for this year's tasks.

World Tour Finals 2018/19 has ended, and we will start the new season soon.

The next two contests will be:

UPD: Due to a fatal trouble (namely, the hardest problem turned out to be known) we had to reschedule it. We are very sorry about this.

And these two will be counted for this season's GP30 race. Like last year, the top 8 (or more, in case we get richer) people of the race ranking will be invited to the onsite finals in the beginning of 2020.

There were several requests to increase the number of contests. Currently our goal is to hold

  • 1 AGC or other all-rated contests per month on average (or 12 per year).

  • 2 ARCs or other <2800-rated contests per month on average (or 24 per year).

(This looks like the maximum number I can handle myself).

We decided to hold a mirror contest of yesterday's finals because there were several requests.

This contest is unrated, but we want to keep it as fair as possible. Please do not participate in case you already know the problems (e.g., participants of Beijing camp), and do not discuss solutions with others during the contest.

This contest is recommended for reds and very ambitious oranges.
