Confuses analytical best solution (what P=NP would be) with numerical good-enough solution (what evolution approximates just well enough to get advantage).
Exactly! Approximate. ~=.
Yes, but that doesn't constitute "solving" NP in P except in having to work out a different approximation method in every instance of an NP problem.
