Variable x; Parameter par; Equation *** Solve the problem Execute_unload 'save.gdx', x; Execute_load 'save.gdx', par = x.l; However, the abov...

Hi, I am a Ph.D. student in chemical engineering at UW-Madison. I tried to obtain marginal values with BARON for a simple NLP problem, and they are not consistent with those from other nonlinear solvers such as IPOPT, CONOPT, etc. Furthermore, BARON does not report the marginal values as shown in th...
