Prime New Year Contest

13’th Prime New Year Contest will start at 0:00 30.12.2016 and finish at 23:59 10.01.2017 Moscow time. Traditionally, Prime New Year Contest consists of problems, which were presented at team programming contests in 2016 and never solved on the contest. For the Prime New Year contest plain ACM rules are used.

Idea of Prime Contest was first implemented by Andrey Lopatin and Nick Dourov at Summer Petrozavodsk training camp at 2003; in Russian word “Prostoj” used in meanings “prime” and “easy”, so, contest was called “Prostoj contest” but was composed of extremelly hard problems, numbered with prime numbers (2,3,5 etc). Since then such a numeration is traditionally used for contests, consisting of very hard problems only.

Registration for the contest is open now.

New Year Blitz Contest

The New Year Blitz Contest (Multiple Language Round) will start at 16:00 31.12.2016 and ends at 08:00 01.01.2017 Moscow Time. Contest will consist of 9-15 problems. Some of those problems are based on problems, used at official or training contests in 2016. Contest rules are based on the ACM system with two important modifications.

  1. Penalty time is calculated as distance between time of first successful submit for the contestant on this problem and 0:00:00 01.01.2017, i.e. successful submissions at 23:50:00 31.12.2016 and at 0:10:00 01.01.2017 will both have penalty time 10 minutes (600 seconds).

  2. Multiple Language Round rule: If for the first successful submit for the contestant on the some problem was used the programming language, which was never used by this contestant in his previous first successful submits on other problems, contestant receives language bonus: his summary penalty time is decreased by 100 minutes (6000 seconds). Note that different implementations of the same language are counting as same language, i.e. Java 6 and Java 7 are both counted as Java, C++ 32 bit and C++11 64 bit both as C++. Additionally, C and C++ are counted as same programming language.
