I just got a mail about Yandex contests this year. Good news: besides the 4 tracks they used last year, they're adding back Algorithms!
Seems like it won't be the exact same contest as before though. The time frame is much shorter — qualification is in the week from 19th to 25th October, the finals (presumably online) are 2 weeks later. It's unclear if there will still be 3 short main rounds in the qualification although it's described as several chances to qualify. T-shirts aren't mentioned, only financial prizes for top 3 and Yandex promocodes for top 100.
At least they're saying it's a continuation of Yandex.Algorithm from 2018 and offering its problems as example problems. Let's hope it will really be like that.
There's already an announcement on Codeforces: Yandex.Algorithm makes a comeback!
Wow, I didn't notice it at all. Better to repeat the info so more people know.
