Hello

I have a simple question. I need to model an optimization problem. The decision variables that I want to compute should be from a known set of values. For example, I want to design a filter using resistors (R), inductors (L), and capacitors (C). My objective function is to minimize the error since I have some design requirements. My constraint here is that I have fixed elements in the lab. The values of R, L, and C should be selected from a fixed set.

What optimization technique is used to solve this kind of problem in GAMS? Is there an example?

Thanks
