Why does the "Status and Results" pane in the GATOOL within the Genetic Algorithm and Direct Search Toolbox 1.0 (R13SP1+) not automatically scroll down when new results are displayed?

Why does the "Status and Results" pane in the GATOOL within the Genetic Algorithm and Direct Search Toolbox 1.0 (R13SP1+) not automatically scroll down when new results are displayed?

To view this behavior, I perform the following steps:

1) Open the GATOOL by typing the following at the MATLAB Command Prompt:

gatool

2) In the "Fitness function" field, type "@ackleyfcn", and in the "Number of variables" field, type "2", then click "Start".

3) After the solution has finished, click "Start" again.

4) After the solution has finished, click the scroll bar in the "Status and results" pane to scroll up, then scroll back to the bottom.

5) Click "Start" again.

I observe that the scroll bar does not automatically scroll to the bottom to show the new result.

This bug has been fixed for Release 14 (R14). For previous releases, please read below for any possible workarounds:

This has been verified as a bug in GATOOL within the Genetic Algorithm and Direct Search Toolbox 1.0 (R13SP1+) in the way the "Status and results" pane does not correctly show new results.

As a workaround, you must manually scroll down to show the new results.
