If you selected an out-of-sample data set from your data file, the optimization screen will display results for both the optimization data set and the test data set while the model continues to evolve. You can stop optimization at any time that you see the results that meet your objective and that model will be the one that will be applied to any data set you choose.
Saving the Model
You can save the model by going to the File Menu, and selecting Save Model. A dialog box is displayed where you can type in a name for the model. You may also click on the 
Save Model icon to preserve the model for later use.
If you did not select an out-of-sample data set, only the results for the optimization set will be displayed during optimization.
