It might be interesting to record our progress and commentary on the contest and problems here :)
--18:05(in GMT +8): We are still waiting for the problems to be available online :)
Meanwhile, PKU(Peking University) gets the overall first blood. Their team member contains two experienced coders which participated in WF 2013, I guess they will get a good result in this WF :)
It seems Problem A is quite easy, many teams solve it during the following two minutes :)
Forget to mention, there are 13 problems this year. I am wondering if it is all hard problems like last year, or some easier problems? The problem type will definitely affect the result of this fierce competition :)
--18:17 nearly 20 minutes passed, no one solve two problems, and we are still waiting for online problems :)
--18:21 It seems the pdf version is out, but we decide not to look at it since we want a virtual competition :)
--18:24 CMU submits F and got -1, Maybe F is the next problems to solve?
And Tsinghua get -1 on C, Zagreb gets -1 on F, I guess C and F will be easier than other problems :)
THU gets first blood on C, and FCEN get first blood on F.
Good start for THU!(I am from THU too), Hope they can keep up the good work :)
Princeton gets first blood on D. What are the members of Princeton this year?
Anyway...The problem is still not online...I decide that if it didn't come before 18:40, we are going to look at the problems first <_<.
"ACM ICPC World Finals 2015 problems to be added shortly after contest start", it seems I misunderstand the world "shortly".
ITMO and Toky solved D, now the problem being solved are A,C,D F, It should be 4 easy problems, I guess during the next 10 or 20 minutes, many teams will solve them too.
--18:40, the website doesn't have problem still, well, We decide to still wait without looking at the pdf version:(
University of Warsaw solved L, well, I think this year's problem will not be like last year, and the first place will end up 10 or 11 problems I guess.
Tokyo solved J, I think rng_58's team are on a good track, they still have more other easy problems to solve :)
PKU solved D and becomes #1, This team is really exciting today :)
Now, 7 teams solved 3 problems :)
Tokyo solved C and becomes #1 again, really good competition :), I'm excited too(Where is the problems to submit online \T_\T).
ITMO got 6 , while Tokyo and Moscow and 5.
They are the three best team in my opinion:) Thus the result is pretty reasonable.
It seems all CN teams solved 4 problems at most ,I hope CN teams can do better later :)
Tokyo now got 6, and back to #1.
Notice that after tourist start to writing C, ITMO got 4 problems in just 20 minutes, it is just insane...
Well, Since the problem is still not out on kattis, I decide to look at the pdf version first \T_\T.
Finally it starts! --19:39 19:53 the log in is broken, so we made a new account. And vfk got problem A. vfk is working on problem D. And he got D soon. I am working on problem F, it is a stupid problem. C is a stupid problem too. I got F and C in a roll.
So we have 4 problems now.
It seems J is a simple FFT, L is a simple Huffman, and H is some kind of math problem... We are working on them now. vfk got J right. dyh is working on H. I am going to code L later.
dyh got H, we have 6 now.
I got L. We have 7 now.
22:05 -vfk got I. We have 8 now.
dyh is coding E, umm, the rest of the problems is quite hard now, we need to be careful.
We got E, we have 9 now.
In the last hour we got K. Seems end up 10 problems <_<
...During the last moment, we are switching on 3 remaining problems B G M and got none of them, so sad T_T.
We got 10 problems and penalty 1066 in the end...
