Hello,
I'm trying to test Couenne on a non-linear non-convex problem that comes
from an AMPL modeling, say myampl.mod . Two naïve questions :
1) What's the exact syntax to generate a .nl file from my myampl.mod ? I
tried unsuccessfully "write gmyampl", "write gmyampl.nl"
2) Does a maximization objective in the original file need to be transformed
in a minimization one , or can Couenne read it directly in the nl file ?
Thanks
