This example demonstrates the functions in AIMMS to solve and tune MPS files.
The two GMP functions used in this example are:
The first procedure can be used to solve a single MPS file and the latter one is to tune one or more MPS files.
For the detailed explanations regarding the usage of the procedures, please refer to
GMP::Tuning Procedures and Functions
In order to solve a single MPS file, you need to open the page “Solve Single MPS File”. On this page you first select an MPS file, set its MIP GAP, and select a solver among CPLEX, GUROBI, CBC and XA. Press the button “Solve Without Tuning” to run the model.
You can tune one or a set of MPS files. The page “Tune Single MPS File” allows you to first tune a selected MPS file, and then solve it with tuned options.
On the page “Tune Multiple MPS Files”, you can first select a number of MPS files by clicking on the button “Select MPS Files” multiple times, then tune selected models all together. Finally, solve one of the models with tuned options.
