First of all I wanna thanks contest organizer for their effort to make it REALLY a good competition ^_^.I would participate next year if I could ^_^

I wanna summarize my trip at VK cup ^_^.

On the first day I arrived at the hotel.I got very tired so I fall asleep >_<.

On the second day there's a AI-contest.It's very interesting!My Robot "DiaoSi"(In Chinese it means a man without money or luck or girlfriends or something) kill two cars in a shot in Round 1.It make me really excited.rudradevbasak's car impress me a lot.It seems just driven by human!

I'm a big fan of tourist,It's lucky for me to seems him in really world!(I fail in China National Team Selection Contest and has no chance to take part in IOI T_T).He's really handsome!

The contest problems is randomly-ordered and very interesting.

(It seems there'll be a online-version of this contest.So I will not talked about contest problems...)

I make a very silly mistake in Problem C.I use a.substr(at-3,at) to get the last 3 chars.But It should be a.substr(at-3,3) T_T..Fortunately I found it at the end of contest..But losing many points T_T.

s-quark take the lead for a long time.But sevenkplus overtook him by 2 successful challenges.At last tourist solve all the problems and take the lead.

But unfortunately tourist's A fail T_T.So sevenkplus take home 30,000. s-quark take home 20,000 $.They're my close friends ^_^. sevenkplus is only 16-years old and will represent China for this year's IOI.I'm looking forward his nice results at IOI ^_^. s-quark is also a very talented student.He's a little older than me and has celebrated his 17th birthday recently.He also make onsite in GCJ Round 3(rank 7-th,But he can't take part onsite round because age-limitation T_T). Before ST I ranked 11-th,the first who don't have price T_T.But some people fail on some problem and I become 6-th after ST.take home 1000$ ^_^.

They also give a cool laptop computer to everyone.I can't wait to use it ^_^.

(-To be continued...It's late now T_T).

 » 9 years ago, # | ← Rev. 2 →   +13 tourist knew that his A will fail before he submitted it =) It was some set of heuristics that passed pretests. something like this.
•  » » 9 years ago, # ^ |   0 T_T... Do you know how to solve it? I still have no idea...
•  » » » 9 years ago, # ^ | ← Rev. 3 →   0 Unfortunatelly, no. The only proved idea is =)
•  » » » » 9 years ago, # ^ |   +8 I think, it's bad idea to discuss it now, before unofficial translation. Thanks.
•  » » » » » 9 years ago, # ^ |   +8 very sorry for that...
•  » » 9 years ago, # ^ |   +27 I wouldn't call that "heuristics" :) It was some sort of attempt to solve the problem using maxflow, but I found a large test case on which my solution didn't succeed in labeling a couple of edges. I still have some confidence that the correct solution uses maxflow, though.
•  » » » 9 years ago, # ^ |   +5 I think so. But I didn't word hark on that problem and have no idea about the details.
 » 9 years ago, # |   +24 +1, it was a great event and it is really lucky and enjoyable to be here. All the thanks to VK and Codeforces and all who helped hold this contest!
•  » » 9 years ago, # ^ |   +20 Agree! I've met a lot of new people, competed in some rounds, lived in the beautiful hotel in the center of Saint-Petersburg. My favorite part — codegame. It was very funny to watch cars, kicking each other with tyres.) I'm fully satisfied, thanks a lot to organisators.
 » 9 years ago, # |   +11 I think I didn't perform well today. I used gdb on three of the four problems. That really took a lot of time. But it seems that most people did not perform well, either.
•  » » 9 years ago, # ^ |   +12 And you still rank #2. Admire!
•  » » » 9 years ago, # ^ | ← Rev. 2 →   +6 Anothor fact is I set the alarm clock last evening, but in the morning I ignored it and slept again until someone knocked the door at 09:28. Similar things happened to sevenkplus, too.
•  » » » » 9 years ago, # ^ |   0 I feel like dreamwalking through whole contest and make many silly mistake (understand problem wrongly,forget to use double,using the java-style substr in c++ and so on).I waste many WA on pretest on them...
•  » » » » » 9 years ago, # ^ |   +29 Whoa, guys, should we multiply your scores by two to calculate your real power? =)
•  » » » » » » 9 years ago, # ^ |   +12 T_T...I know it's stupid to take such excuses...I will practice more to improve my skill...
 » 9 years ago, # | ← Rev. 2 →   +13 oh.. it motivates me to train harder ^_^ I hope, one day I'll become strong enough to participate in such kind of competition ^_^
•  » » 9 years ago, # ^ | ← Rev. 2 →   +17 Best wish to you to make onsite next year ^_^.In addition, your picture seems a character from the anime "sola"?I enjoyed that anime last year ^_^.
•  » » » 9 years ago, # ^ |   +5 Thanks ^_^ Yes, you are right, it is Aono from "Sola" on my picture. I like kuudere characters at all ^^
•  » » » 9 years ago, # ^ |   +3 I think maxflow can solve it. Orz... Min Cost Maxflow ...Is it right.
