Big thanks to KAN who uploaded these two contests with ghosts and everything and even tuned up TLs a bit for CF.

2019-2020 Зимние Петрозаводские сборы, Almost Algorithmic Contest

2020-2021 Зимние Петрозаводские сборы, контест Almost Retired Dandelion (XXI Открытый кубок, Гран-при Нижнего Новгорода)

The second contest was used as an OpenCup stage last season, while the first one was not published anywhere (except some secret Chinese servers I assume).

Selfpromotion: I really think that these two contests are amazing. The difficulty is comparable to ICPC WF or harder regional finals (but with a smaller number of easy problems, who needs them anyway).

I was the author of more than half problems from both contests, with additional problems contributed by KAN, vepifanov, ashmelev, kristevalex, Merkurev and WYOCMWYH. I also want to mention the authors of three original problems that were improved and reused in the second contest: Ferume, fake123 and dario2994.

Enjoy!
