Hi Codeforces Community,

I would like to invite you to participate in TOKI Open Contest. TOKI Open Contest is our (Indonesian's) monthly/bi-monthly online contest. Starting this month, we have decided to make this contest international :) Every problem is written in both Bahasa Indonesia and English.

TOKI Open Contest February 2017 will be held on Saturday, 18 February 2017, 19.00 — 21.00 Western Indonesian Time (UTC+7). This contest is written by athin, anthonyhkf, aguss787, and jonathanirvings.

Several details related to the contest:

The contest will use ACM-ICPC scoring type.

There will be FIVE problems with various difficulties but the weight for each problem is the same. The contest time is 2 hours.

Any non-Accepted submission will get 8 minutes penalty (but the penalty will only be counted after the respective problem got Accepted)

The rank will be sorted according to the most number of solves (problems with Accepted verdict). If there are ties, it will be determined by least (sum of solving time + sum of penalty)

The allowed programming languages are C, C++11, Pascal, Python 3, and Java 8. However, please note that we do not ensure that every language can solve all the problems on the given time limit.

The contest will be held on https://competition.ia-toki.org/contests/161. Registration is already opened at the same place. Registering the contest requires a TLX (http://competition.ia-toki.org) account. You may need to register for an account if you don't have one.
