The progress chart (CP models)

Analyses the results of the solve process displayed as a chart in the IDE.

If you execute a constraint programming model solved with the CP Optimizer engine, the progress chart is slightly different from the progress chart of CPLEX models. To observe it, you are going to open the route project.

  1. Use the File > New > Example menu command to open the Call route example.

    The route project will appear in the OPL Projects navigator.

  2. To run the model, open Run Configurations, right-click on Basic Configuration, and select Run this from the popup menu to execute the run configuration.

  3. Click the Statistics tab.

The progress chart shows the variation of the objective. The yellow points show when solutions are found and the green line basically follows these points, showing the evolution of the best solution found over time.
