last year's results might be of interest

Generally top 20~25 senior scores advance to stage 2. The required score fluctuates by year. In 2004 it had to be over 45 (out of 75)

and unless my math is off.. out of 623 participants
52 people have scored more than 0 on problem 4
38 people have scored more than 0 on problem 5

Generally, if you can hit 60, you're almost guarantteed to go to stage 2. The cutoff is usually in the mid-50s, last year was an exception because space turtle threw many of the serious practicing people off (I never saw something like that on other Olympiads before). I hope Donny don't make any problems this year.
It's quite funny that for the past few years, 4 was a harder problem compared to 5. (DP vs. ugly 3D-geo for 04, modifiedMST/dijkastra vs. suffix tree for 03)

Another interesting post. Might as well be removed by one of the moderators to avoid a flame war.

I have O(TE+ElogE), but with a pretty big constant. I'm still trying to reduce the constant. It turned out that the algorithm I used was right, I just forgot to sort the edges by increase value in the edge graph. :(

Oy, can someone please please explain to me the purpose of the first for loop in the main procedure of the quicksort algorithm? Is it something that does nothing for the first iteration?

don't know if you guys heard of dynamic programming.. it has been used intensively in the contest for the last 2 questions... recursive can do it but just take too long and not efficient..
