Revision en5, by VastoLorde95, 2015-07-21 21:10:08

Hi, I am unable to understand the solution provided in the editorial of this problem. I read the explanations in the comments but can't seem to understand them either.

Specifically, I am stuck on this part of the editorial —

"For every arrangement, the minimizing player can guarantee himself the result of at most "

I don't see the logic behind this formula.

Also in the editorial dpmax(v) is given as but in the sample solution 10973864 it is given as . How is that the same?

I have been at this for hours now! Can someone please help me? Thank you! :)
