AtCoder World Tour Finals 2022 will take place on Sep 8th and 9th. We have two contests, one for each day, and we will combine the results of the two contests to declare a champion. Contest Day 1: https://atcoder.jp/contests/wtf22-day1 Contest Day 2: https://atcoder.jp/contests/wtf22-day2 To reward those who advanced to the Finals multiple times, we will introduce a special tie-breaker this time: a contestant will get X points before the start of the contest where X is the number of times they advanced to the Finals. We will also offer mirror contests for them. They have the same problems as Finals and happen at the same time. Mirror Contest Day 1: https://atcoder.jp/contests/wtf22-day1-open Mirror Contest Day 2: https://atcoder.jp/contests/wtf22-day2-open They are rated for people with 2000 or higher rating, but they don't count for GP30 points. <font color="red">UPD (Sep 2nd 2023)</font> - The rated range changed from 1200-inf to 2000-inf.
