12’th Prime New Year Contest will start at 0:00 30.12.2015 and finish at 23:50 10.01.2016 Moscow time. Traditionally, Prime New Year Contest consists of problems, which were presented at team programming contests in 2015 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.
