Have you checked the GAMS user guide?

Hello sir, yes sir i have gone through GAMS user guide but i am unable to solve the problem which has many errors i am unable to come out from it

Dear Sahan,

MINLP problems are not suitable models to solve especially for large-scale optimization problems. Both BARON and DICOPT are the most appropriate solvers of GAMS which can help you.

Dear Morteza,

Thank you sir for your suggestion. I will try to implement using these solvers

Thank you,

Hi Sahan, I am planning to do MINLP optimization for membrane-based gas separation network design. Could you please help by providing materials and links which help as beginner? Thanks.

If you could transform your problem from MINLP to MILP using some linerization algorithms, you will probably end up with optimal solution. However, from my experience, CONBONMIN or SBB are the most usable algorithms to solve my problem. But again, it is a problem based.

My suggestion is to try different base solvers each time for the NLP and MIP because they are the most important factors affecting the MINLP algorithm.

you can see this: https://github.com/gptshubham595/CL643

I have added one of my assignment where I have defined every type of problem and how to modulate it using CPLEX [LP, MILP] as well as GAMS[LP, MILP, NLP, MINLP]

Hi，I am modeling RON in GAMS，do u need my help？
