Hello everybody,
I have a general question. Suppose that I want to code a metaheuridtic in Matlab and I have to use optimization for my subproblems inside the heuristic. I was wondering if it is faster to use the optimization toolbox in Matlab or have a join between Matlab and GAMS and read the results from GAMS to MATLAB. Which one is faster? My subproblem is a simple assignment problem.
Thanks

I suggest you to call Cplex (solver) via matlab to solve your optimization problem (sub-problem). I have solved my metaheuristic using both ways, and it takes more time when you call GAMS from Matlab to solve the optimization problem and read the results for many iterations (loop).
Good luck
