The statistics table (CP models)

Analyses the results of the solve process displayed as statistics in the IDE.

The statistics table and progress chart work in a very similar manner for models solved with the CP Optimizer engine. However, take a look at the route example to observe the differences.

Click the Statistics tab after executing the Basic Configuration for the route project. The statistics are on the left column of the table, Statistic.

Statistics window

The top level of the Statistic tree indicates the solving engine (CP). You see certain statistic values change dynamically as the solving takes place. The statistics items are:

  • Number of constraints after initial propagation

  • Number of variables

  • Memory usage (including after initial propagation)

  • Number of choice points

  • Number of fails

  • The objective

Click on the Solutions tab to see the number of solutions obtained.

You can change constraint programming parameters by changing values in the Constraint Programming page of the settings editor. See also Constraint programming options in IDE Reference.
