Run parameters (Decision Optimization)

There are various run parameters that you can select for the optimization solve in the Decision Optimization experiment UI

Run configuration parameters

When you click the Run Configuration icon next to the Run button in the Model view of the experiment UI, a window opens showing you the currently set parameter values. You can click Add parameter and then choose from the following parameters from the Select Parameters drop-down menu.

Name Type Description

For CPLEX ma.cplex.parameters.<Python cplex parameter name>

For CPO ma.cpo.parameters.<Python cpo parameter name>

Python names for CPLEX and CPO parameters can be entered with the prefixes ma.cplex.parameters. or ma.cpo.parameters.

Once you have set the run configuration parameters they will remain with those values for all subsequent runs for that scenario. You can set different run configurations for different scenarios.

You can remove set parameters by hovering over the parameter displayed in the Run configuration window and clicking the remove button.
