Codeforces Round #488 by NEAR

Revision en20, by AlexSkidanov, 2018-06-17 20:12:08

UPD note that the score distribution has changed UPD2: LHiC found a bug in the author solution of div1-F. We are working on the situation.

Hi, everybody,

Codeforces round 488 for both divisions will take place on 16.06.2018 19:35 (Московское время). The round will be 2.5 hours long (which is 30 minutes longer than usual).

The contest is created by NEAR and its friends. NEAR is working on teaching machines to compete in programming competitions. Read our blog post to learn more about the state of the art in the program synthesis today, our vision, and how you can help us bring this vision to reality.

The contest will feature 6 problems for each division, with 4 problems shared across them.

The problems for the contest are from the test rounds hosted on a system JavaBlitz last year. If you participated in any of the JavaBlitz rounds, you shall not participate in this round.

The score distribution in the first division is 500-1000-1000-1500-2250-3000

In the second -- 500-1000-1500-2000-2000-2500

The round is rated for both divisions.

All problems are initially created by myself, Alexander "AlexSkidanov" Skidanov, and by Nikita "FalseMirror" Bosov. David "pieguy" Stolp, Alexander "AlexFetisov" Fetisko, Marcelo "mnaeraxr" Fornet, Nikolay "KAN" Kalinin and Mikhail "cerealguy" Kever helped tremendously ensuring the high quality of the problems.

As a closing note, we are constantly looking for people to help us label competitive programming data for research. Read more here.

Congratulations to winners!
