Configuring the Technique and the Execution Options

You can select the technique and set any tuning parameters associated with the technique. In addition, you can also set options that you want the adapter to take during execution.

  1. From the Flow section of the action bar, click Optimization and drop it on the process diagram.
  2. Double-click Optimization .
    The Optimization Editor appears.
  3. From the General tab's Optimization Technique list, select the technique of your choice.

    Information about the technique appears in the Optimization Technique Description area on the right side of the editor.

  4. Optional: Review the information in the Optimization Technique Description area.
  5. In the Execution Options area, set the following, if available:
    OptionDescription
    Execute in parallel Click this option to run design points in parallel, small batches. The size of the batch depends on the number of selected design variables for numeric techniques or the size of the population for exploratory techniques.
    Restore optimum design point after execution Click this option to set parameters to the best design point after execution. If this option is not selected, the optimization keeps all parameters at their last values (last execution of the subflow) after execution.
    Re-execute optimum design point Click this option to force the optimization adapter to re-run the optimum design point after the optimization ends. Re-executing is recommended if there are some output parameters that are not directly involved in optimization, but their values depend on the values of design variables (for example, output files).
    Use automatic variable scaling Click this option to scale design variables using their respective ranges (that is, distances between their upper and lower bounds). Optimization Process Composer removes the Scale Factor column from the Variables tab because the scale factor values are calculated automatically.

    Note: You must define all upper and lower bounds (or allowed values) for all design variables when this option is selected. If some design variables do not have bounds, you will not be able to use this option.

    Execute subflow only once Click this option to run the subflow only one time and to calculate the constraints, objectives, and penalty values. This is useful in simulation processes that need to turn the driver logic on/off parametrically. This option is also helpful in the debugging process if the simulation process does not run successfully.
  6. Optional: Map the Execute subflow only once option.
  7. Select Ok to save your changes and to close the Optimization Editor.
