Solver and model options with frozen model

GAMSPy
1

Hi all,

I have been trying to implement the iterative model solving using the ** Frozen Solve** option. While this option is working, the solve statement doesn’t seem to pick up the solver_options and options parameters when called. For example, I can reproduce the frozen solve transport example from the User Guide ( Frozen Solve — GAMSPy documentation), when each iteration is solved with different solver, but when applying some options on the model (for example threads) or solver (for example lpmethod in cplex), it seems to have no effect.

I would appreciate your help with that.

Best regards,

Adam

Hi Adam,

This seems to be a bug. Thanks for reporting it. It will be fixed in the next release which will be available next week.
