Me too.

Will there be a virtual board of your result? Thanks in advance.

"I bet there are very few places in the world where your boss can come up to you and propose participation in ACM ICPC training camp :)" That sounds REALLY good!

I know, they are not hard for you. You can solve at least 5 such problems in a 5-hour contest.

Guessing the difiiculty of problems is really important in OIs, that might be not so necessary in IOI since at most one problem cannot be solved by top contestant like you and me. But if the poblems are more challenging like China's Secletion Contest or even China's NOI, working on a hard problem will be a fatal mistake.

OI is not a algorithm competition but a strategy competition. That's why I dislike it.

In my opinion, adding tests during the contest is something bad. But in the situation that the origional tests are not strong enough, it is worthy to do that bad thing. Idealistically, the tests should accept a solution if and only if which is perfectly correct. A solution which fails in the additional tests fails due to the incorrectness of itself, not some subjective reason.

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.

I think so. But I didn't word hark on that problem and have no idea about the details.

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.
