This year's TopCoder Open includes, in addition to onsite final round, four onsite events, which take place in various cities around the globe simultaneously with the sub-rounds of round 2. As a result, the times for these rounds become known later than usual. The times for rounds 2A, 2B and 2D have already been announced, and now the time for round 2C is announced as well.
Round 2C will take place on July 18th in Tokyo, at the office of Dwango Co.
Like on the other onsite events, there will be a hackathon and t-shirts. Unlike the other onsite events, there will be round 2 explanation by iwiwi and rng_58. The event will begin at 11:00 AM local time, and the round itself will start at 3:00 PM (6:00 AM UTC). There will be a parallel round for onsite participants who didn't advance to round 2, as well as for everyone who have already advanced to round 3. If you plan to participate in the onsite event, don't forget to register, because just 100 participants would be able to do it.
As a reminder, all onsite events are optional. If you advanced to round 2, you can participate online.
I don't understand point of those onsite events :P. Moreover — why there are so big spaces between dates of all rounds causing that 3B is nearly half a year after 1A :P?
