No Longer a potential proof of P != NP

Berg and Ulfberg and Amano and Maruoka have used CNF-DNF-approximators to prove exponential lower bounds for the monotone network complexity of the clique function and of Andreev's function. We show that these approximators can be used to prove the same lower bound for their non-monotone network co...

Re: Foolish question debunked. Move on, nothing to see.

To be clear let me discuss why n is bounded in this fashion. n=1 isn't defined in this set for a circle, since we defined a circle as two points. n= 2 should work. But it fails the condition of ending where it started. That circle isn't closed. To close it you would have to steal the origin for n=1...
