Just curious, what is this polynomial?
the polynomial goes like this:
# MurphyE (Bf=3.41e+06,Bg=1.57e+06,area=2.86e+13) = 9.43e-10
# lognorm 37.82
In fact, I am also curious about the form it has before the root optimization. it is the 557 polynomial after size optimization, but is the best after root optimization.
