Test All Button
Evaluates the performance of all the models in the History Panel on the testing set, showing their respective fitnesses and R-squares. When in Prediction Mode, then this button is disabled.

Test Current Button
Evaluates the performance of the selected model on the testing set, showing its fitness and R-square. When in Prediction Mode, then this button is disabled.

Refresh All Button
Evaluates the performance of all the models in the History Panel both on the training and testing sets, and updates all the fitnesses and R-squares. For instance, this button is particularly useful when you have changed the fitness function after a run and would want to evaluate the performance on the training set with this new fitness function.

Best of Run – Training
This heading is used to identify the best models of the run on the training set in terms of fitness and R-square, showing also the exact values of their fitness and R-square. For reference, the value of Max. Fitness on the training set is also shown.

Best of Run – Testing
This heading is used to identify the best models of the run on the testing set in terms of fitness and R-square, showing also the exact values of their fitness and R-square. For reference, the value of Max. Fitness on the testing set is also shown. When in Prediction Mode, a dash is shown in all the boxes under this heading.

Model Column
In this column are shown the names of all the best-of-generation models created in the run. By clicking a model, you are making it your active model. By clicking the column heading, GeneXproTools allows you to sort the models in ascending or descending order.

Generation Column
In this column is shown the number of the generation in which the model was created. By clicking the column heading, GeneXproTools allows you to sort the models in ascending or descending order.

Program Size Column
In this column is shown the program size of all the best-of-generation models. By clicking the column heading, GeneXproTools allows you to sort the models in ascending or descending order of their program sizes.

Training Fitness Column
In this column is shown the fitness obtained by each model on the training set. By clicking the column heading, GeneXproTools allows you to sort the models in ascending or descending order of their training fitnesses.

Testing Fitness Column
In this column is shown the fitness obtained by each model on the testing set. Note that, after a run, only the fitness of the best-of-run model is shown; all the others are set to zero. In order to update these values, you must either click on the Test All or Test Current buttons. When in Prediction Mode, though, a dash is shown in all the entries under this heading. By clicking the column heading, GeneXproTools allows you to sort the models in ascending or descending order of their testing fitnesses.

Training R-square Column
In this column is shown the R-square obtained by each model on the training set. By clicking the column heading, GeneXproTools allows you to sort the models in ascending or descending order of their training R-squares.

Testing R-square Column
In this column is shown the R-square obtained by each model on the testing set. Note that, after a run, only the R-square of the best-of-run model is shown; all the others are set to zero. In order to update these values, you must either click on the Test All or Test Current buttons. When in Prediction Mode, though, a dash is shown in all the entries under this heading. By clicking the column heading, GeneXproTools allows you to sort the models in ascending or descending order of their testing R-squares.
