takes place on September 8-9 in Tokyo, Japan.
When AtCoder announced its own onsite competition, the World Tour Finals, back in 2017, the world of onsite algorithmic competitions was quite packed. They have managed to host one edition of the WTF before the pandemic hit. All onsite competitions were cancelled or moved online during the pandemic, but instead of returning after global travel became relevant again, most were cancelled completely: Google Code Jam, TopCoder Open, likely Meta Hacker Cup. There were a few more Russia-based onsite competitions that are of course no longer a thing. ACM ICPC and high school olympiads such as the IOI are back in the onsite mode, but they have age upper bounds for participation.
AtCoder did not move the WTF online, instead they kept running the yearly qualification cycle, promising to invite the top 8 from each year to the onsite round in Japan when it becomes possible again. This is finally happening in two weeks! 18 finalists out of the maximum of 32 from the four qualification cycles will compete on the same problems over two competition days. This approach lies in contrast to the ACM ICPC approach where the finals for the 2022 and 2023 seasons are happening together in Egypt but the actual competitions will be kept separate. Which one do you think makes more sense?
I am really excited both for the competition (where to be honest I no longer stand a chance), and for the onsite event atmosphere. As an added twist, AtCoder have announced the online participation option for the future WTFs; I can't predict how this will work out, but when TopCoder did the same for TCO22, so few people decided to come onsite that they decided to cancel the onsite event altogether. Therefore this might be the last onsite event without the age upper bound ever :)
Thanks for reading, and check back next week!
