Dear all,

I'm working on a invers problem (i.e i try to determine some model parameters fitting some experimental data)

I'm wondring if i have to put the model unknown parameters as : Variables or Parameters?

Will GAMS bi able to look for the values of the unknown parameters if i put them as PARAMETERS?

Thank you in advance.

No parameter are know entities. Variables are determined by the solver subject to the equations and the objective.
