Creating and executing a different configuration

Describes how to create a second run configuration, then populate and execute it.

You will now create a second run configuration, then populate and execute it.

To create and execute a second run configuration:

  1. In the selected project, right-click the Run Configurations folder and choose New > Run Configuration from the menu. A new run configuration with the default name Configuration2 is added.

  2. Optionally, rename the run configuration, by selecting it, right-clicking and choosing Rename from the menu. In this example, Configuration2 is renamed Barrier.

  3. Drag and drop the files myFirstProject.mod, product.dat, and your new settings file newsettings.ops into the new Barrier run configuration.

    The OPL Projects Navigator should look like this.

  4. Right-click in the project and select Run > Barrier from the menu to execute the model with changed settings.

    The CPLEX® engine now uses Barrier as the value of the algorithm for continuous problems.

Observe the differences in the output tabs.

  • The Solutions tab displays the same solution (see Figure 2).

  • The Engine Log tab shows a different report.

  • The Statistics tab shows a different algorithm (Barrier) and number of iterations.
