Configuring the Objectives

You can select the parameters that will be used as objectives during execution. The Approximation Loop and Pointer-2 strategies have the same objective attributes. In addition, because both strategies have the same general intent as the Optimization component, their design parameters have the same attributes as the Optimization component.

  1. Double-click the Exploration component icon .

    The Exploration Component Editor appears.

  2. From the Exploration Component Editor, click the Objectives tab.

  3. Right-click in the table to access various options for working with objectives.

    For more information, see Setting Table Options.

  4. Perform the following actions, which may vary based on your model design:

    1. Determine which parameters you want to use as objectives by selecting the corresponding check boxes in the first column. Alternatively, you can click Check to add all the selected parameters (including array elements) as objectives. To clear all the parameters, click Uncheck.

      If no parameters are selected, you will be prompted to add all parameters as objectives.

      When a subflow parameter is selected as an objective, a corresponding parameter is created in the Exploration component.

    2. Click the Direction column to specify whether or not you want to minimize the objective, maximize the objective, or set a target for the objective.
    3. If you selected target in the Direction column, set the objective’s target in the corresponding column.
    4. Set the objective’s Scale Factor and Weight Factor in the corresponding columns.

  5. If desired, click Edit at the bottom of the editor to set attribute values for multiple objectives.

    For more information, see Editing Attributes for Multiple Parameters.

  6. If desired, map any of these objective attributes to parameters.

    For more information, see Mapping Options and Attributes to Parameters.

  7. If desired, click Disable strategy (execute a single run) to disable the Approximation Loop strategy when the Exploration component executes and instead execute the subflow once.

  8. Click OK to save your changes and to close the Exploration Component Editor.
