Lol I recognize a name on that team
Apparently he is good at spelling too
Wouldn't be surprised if he was autistic :/
Who else would be able to muster 2 years of spelling training looking through the whole dictionary learning how to spell exactly everything just to win the spelling contest...
yeah I think he has some type of asperger's. I went to math camp with him twice and was in the booth beside him at ISEF (international sci/engineering fair). He's a fucking genius (no shit, he was 2nd place in the world this year and is one of the few few people who will go to IMO 4 times, especially for such a strong country as the USA) but is not so good socially. I hate how people make fun of him though Also I believe I first saw an interview of him for the spelling bee on the way to a math competition, and that was after he received Honorable Mention (top 24) on the USA Math Olympiad (the hardest high school math contest in the US)... in 8th grade. wtf.
Anyway I solved 1,2,4 probably the day they came out (respectively, since there's 2 days of this... 4.5 hours, 3 problems per day.) Been spending a little time on #5, which supposedly Terence Tao (Fields medalist-top prize in the world in math) claims is the hardest problem on the whole thing... I got up to 5*2^(5*2^55-1) heh? that's still way smaller than 2001^2001^2001 though D:
My solution to #1 was kind of blegh, pretty similar to arbiter_md's (I mean I guess they have to all be similar)... plug in x=0, y=0 and you get that either
f(0)=0, [f(1)]=1, or f(1)=0 or [f(0)]=1. The latter two cases give f(x) = 0, f(x) = c where 1<=c<2 respectively, while plugging in x=2, y=1/2 for the first gives a contradiction since you get 1=0*(something).
#2 was pretty easy for #2 since it's well-known that D is the circumcenter of BCI... though I didn't realize that the diametrically opposite point of I in circle BCI is actually the excenter opposite A -.-;; luckily that's just something to notice and doesn't affect the solution.
I posted my solution to #4 on AoPS but I was pretty stupid and overkilled it with inversion @_@
anyway the point of this post is to make myself feel better for failing to make IMO for the fourth (and last) year in a row (not doing any math isn't helpful ). I believe at least one person on the US team has an account on TL though, and he's incidentally my only friend who can compete with me in FPL ... Also Stryker went to IMO in 2005 I believe (which I think is where I first heard of him :O and then I realized he was really fucking good at SC too and was like O_O)

sup I didn't either darn hamster our grade fails also lol I thought you learned how to solve G3s?

If you go by how many that solved the problems the difficulty of the problems goes like this: 6>3>5>2>1>4
Knowing too much makes it hard to gauge how hard the problems are.

haha that's probably true.
Also I believe NK was disqualified for sneaking some type of notecards into the testing room... I wonder if that coach will defect? LOL
also Kazakhstan has never done this well before, but it was in their home country so :O
Oolala time for some geometry fun. I remember for my high school geometry class we had to present a problem and work out a solution as a "final" of sorts, so I pulled some random IMO problem. It took quite a bit longer than expected -_-
Damnnnnn. China is amazing. Even though this is my first time seeing IMO results, it doesn't suprise me to see who's in top 5. Khazastan is a bit surprising though.

Whoa, you did IMO problems for your high school geometry class? :<
The closest I ever got to the IMO was being one question away on the AIME (given my AMC score) to qualify for the USAMO T_T...never got an A in math in high school though :/

Stats major in college haha.
apparently in China they do proofs all the time so it's whatever ;P
plus some IMO geometry (or problems in general) is not that hard, especially older problems
the easiest IMO problem ever was probably IMO 1959 (the first IMO) #1 though... "prove that (21n+4)/(14n+3) is irreducible"

Edit: I solved problem 1,5 and 6, don't want to bother with the geometry ones and I don't get anywhere on problem 3. Having taken a ton of maths courses really helps, the first problem is trivial then.
I guess what these countries do is to teach their participants a lot of number theory and geometry so that they can solve these questions, since that is all this. Anyone know how to solve number 3? Probably something simple I just don't see right now.

lol, i noticed the same thing ... Asian pride baby!
