ABBYY Cup 2.0 – Hard!

**UPD1: ABBYY Cup 2.0 is completed! **

UPD: Editorials here. They will be updated again :)

Hey, everyone!

We remind you that today at 16 PM the first division of ABBYY Cup 2.0 starts!

This contest is rather hard to be solved completely and it is aimed at the first division Codeforces participants!

Don’t forget to register for the contest!

The duration of the contest is 5 hours. You should solve six problems (one of those is heuristic). The tests are split into three categories (easy, moderate, difficult), they are worth 20, 30 and 50 points, respectively. Only fully passing a group of tests is counted. When contestants win the same number of points, the penalty time is counted by the ACM rules. Fully solving some group of tests is counted as submitting an ACM-problem and will determine the penalty time you get. The first division (hard) contest will be a rated event for any participant despite of the participant rating and type of participation.

We hope you’ll enjoy the contest! Good luck : )

It will be good that for each contest there will be a small info table in the post which will answer all standard questions about the contest, like "for whom it will be rated", "problems are ordered by difficulty or not", "score distribution mechanism", etc, so that people wouldn't ask same questions again and again in comments. Sometimes that information is specified in the text in different places, so gathering them all into one table will make it more easier to see all needed info at once.

Very enjoyable competition, I do not regret missing out on COCI for this :D

I particularly enjoyed solving task E (E1 and E2 at that, I had no idea how to cope with the "noise" — but still, it was a very interesting task) :)

    We can apply a (say 5 x 5) "median filter" which can handle this kind of salt and pepper noise. Provided that the shapes are far enough from each other, there is only a small chance that some of them merge after filtering the image.

I enjoyed the competition very much. I think we should have more of these 5 hour contests in which the solutions are judged during the contest time (i.e. ACM style rules).
