Leave the algorithm settings at the defaults and click OK to start optimizing the design.
When you click the OK button on the Optimal Design dialog, the Optimizing Design dialog appears, containing a graph. This dialog shows the progress of the optimization and has two buttons: Accept and Cancel. Accept stops the optimization early and takes the current design from it. Cancel stops the optimization and reverts to the original design.
Click Accept when iterations are not producing noticeable improvements; that is, the graph becomes very flat.
