Hello!
I would like to plot the performance of a model over time, i.e. the objective function value or gap vs. execution time. Is it possible in gams? Or maybe anybody knows how to save these informations into vectors?
Thanks in advance!

Hi,
It depends on the solver you are calling. For many MIP solvers there is a option called MIPTrace or SolveTrace which allows you to get this information. The following presentation has a short overview of this feature (starting at page 10):
