Bilevel programming solved with GAMS calling MATLAB

GAMS
1

Dear GAMS community,

I am currently forming a bilevel programming model which I want to solve with MATLAB.

For this reason I believe the problem (obj functions and constraints) will be introduced to GAMS and eventually call MATLAB so as to utilize the GA function.

My question is whether there is a documentation of how to pass solutions from GAMS to MATLAB, process these data with MATLAB and return them to GAMS.

Due to the fact that I am new to this kind of modelling, any additional comments are welcome.

Thank you in advance,

Konstantinos: Why don’t you try a quick and dirty solution, like
PUTTING to a text file from GAMS, reading it from MATLAB and then back
to GAMS with $include ?

You can use any scripting language you know to handle this (python, VBA, etc).

Hope to help!

Claudio,

thank you for your response.

Is there a toy example so I could see how to implement this?

Thank you very much

Konstantinos
