Hello!
As you may have noticed, this year's Central European Olympiad in Informatics (link) will take place from July 23rd to 29th, in Slovakia, and we'll hold mirror contests for each day here. We want to preserve the (subtasks, no hacks) format of the competition, so the mirrors will be unrated, but I still encourage you to find the time and participate.
I think the problems will be fairly well-balanced — not very hard for LGMs, but not too easy either, and everyone should be able to find subtasks on their own level.
The mirrors will start shortly after the official contest starts (that's how it's scheduled right now) or shortly after it ends.
The problems were prepared by majk, Monika Steinová, misof, Hodobox, Peter Perešíni and me.
Also, thanks to MikeMirzayanov for Codeforces and Polygon.
You forgot to thank MikeMirzayanov. Now the contest is doomed.
O shit, now it will probably end up unrated.
The mirror will start at 14:05 UTC on both days, that is, after the on-site contest finishes.
Will there be a public scoreboard during the onsite competition?
Probably, yes. I'm not sure if it isn't an unfair advantage for the mirror, but it's not like it's possible to prevent accidental leaks post-contest anyway, so whatever. It also needs to be implemented, but that isn't hard.
