d000hg 7231 posts	Petr and tomek have a stage to themselves, and the monitors for spectators for these two are also next to each other... guess where 70% of the spectators are!

d000hg 7231 posts	It looks tricky. 8min in and only a couple of people have started coding. All competitors start with the 250... tomek is being slightly more cautious perhaps?

d000hg 7231 posts	even Petr looks uncertain. Unusually, he started coding and then stopped for a bit...

d000hg 7231 posts	Most guys are now coding, but coming up or 20min in, nobody looks very certain. A lot of thinking and slow, sporadic coding... ...but Petr and ACRush submit suddenly. Eryx is testing.

d000hg 7231 posts	But ACRush made a mistake... his solution fails an example test! After a little thought, Petr moves onto the 500. Meanwhile Eryx submits the 250 and immediately opens the 500, as does ardiankp tomek has alos submitted the 250. We have 5 submissions from 195-177 points. Yarin seems to have given up on the 250 and has opened the 1000... probably his only chance is to solve that, since someone will likely get the 250 and 500.

d000hg 7231 posts	ACRush resubmits the 250 and moves on... but he's 50 points behind the leader, Petr. [h]tomek[h] opens the 1000 instead of the 500.

d000hg 7231 posts	So the 1000 is essentially a packing problem... easy to understand at least. tomek seems to have ome idea, and has just begun coding. Meanwhile Petr is under way on the 500.

d000hg 7231 posts	Yarin now opens the 500... he has all 3 opened now with no submissions. ardiankp seems to have given up on the 500 and opened the 1000. We've got 8 submissions on the 250 now, Petr leading by 9 points, tomek in 4th and ACRush still the lowest score.

d000hg 7231 posts	Suddenly Eryx takes the lead, submittin the 500 first. But lierally sconds later, Petr also submits and is ahead again by 10 1 point! (thanks for the correction connect4)

connect4 1006 posts	Minor editor's note: he's actually only up by 1 point. Very nice strategy by Petr, to test while waiting for other competitors to submit.

d000hg 7231 posts	Both Petr and Eryx open the 1000 quickly, while ~~tomek~~ ACRush now submits the 500, moving up into 3rd place, but over 50 poins behind the 2nd place Eryx.

d000hg 7231 posts	With only a little over 30min remaining, and the top 2 guys doing well, tomek really needs to get somewhere on the 1000 soon, to have a good chance... Petr is totally capable of scoring very highly on the 1000.

connect4 1006 posts	bmerry and radeye were discussing a mincost maxflow solution for this problem in the arena. As Petr has coded this from scratch before in insanely good time, he will be in fantastic shape if he finds this solution.
