We will hold AtCoder World Tour Finals 2024.

List of Finalists:

• Contest URL: https://atcoder.jp/contests/awtf2024
• Mirror Contest URL: https://atcoder.jp/contests/awtf2024-open
• Start Time: http://www.timeanddate.com/worldclock/fixedtime.html?iso=20240712T1230&p1=248
• Duration: 300 minutes
• Number of Tasks: 5
• Writer: maroonrk
• Tester: hos.lyric, yosupo, maspy, nuip, HIR180, sigma425, nok0
• Rated range: Unrated

The point values will be 700-1000-1500-2000-2000. We don't freeze the standings in the contest.

AtCoder World Tour Finals 2024 is an international onsite contest. We have invited top-runners of AtCoder Race Ranking 2023 to Tokyo. Since cnnfls_csy (8-th in the race) couldn't come to the Finals, ugly2333 has advanced as the runner-up. For more details, please visit this page (https://info.atcoder.jp/more/contents/awtf/2024) (this is under construction, though).

Note that, unlike last year, the mirror contest is Unrated and the standings is hidden.

About Streams

On the contest day, we will stream the contest on our YouTube channel. This year we have a special guest Petr! I and he will be watching the contest and discuss problems. Obviously, Finalists should not watch the stream during the contest. The mirror contest participants can watch it since there's no way to prevent it. This is why the mirror is Unrated and the standings is hidden.

And last but not least, we had set up a "confessional booth" this year. This idea comes from the chess tournaments (example) — a room where you can go during the contest (one at a time, obviously) and say something to be shown on stream. This is a new attempt and we hope it makes the stream more interesting!

We are looking forward to your participation (in the mirror or stream)!

Original Post on AtCoder

The rule for the AtCoder Race Ranking 2023 said we would invite top 8 runners of the ranking to the onsite final in 2024. We have decided to increase the slots by 4 and invite top 12 finalists to AtCoder World Tour Finals 2024.

You can see the current ranking here. Note that we will hold AGC065 on Dec 17th and it will be the last contest that counts for this season's GP30 scores. We are looking forward to your participation.

AtCoder World Tour Finals 2022 is an international onsite contest. We have invited top-runners of AtCoder Race Ranking 2019-2022 to Tokyo. We will combine the results of the two contests to decide on the champion. The score of the participant is calculated as (score of Day1) + (score of Day2) + (the number of Advancements to Finals). The time penalties are also summed. You will see this combined score in the standings during the contest. Considering that the special rules will affect strategies of participants, the Finals itself is unrated. Note that, unlike other onsite competitions, there's no freeze in the contest.

Mirror contests don't have special rules, so they are just two independent rated contests. They happen at the same time as the Finals (=13:00 in UTC+9), so they are much earlier than usual AtCoder contests.

We are looking forward to your participation!

UPD

With the help from lperovskaya and ICPC streaming tools, we will stream the Finals in our YouTube channel. Since we have rated mirrors, there is no commentary and we will only show the contest venue, webcam videos of Finalists, and standings.
