Configure Convex Hull on Inputs
In/Outputs menu >Hull on Inputs
Or
In the optimization windows: Hull (2D) button.
The Convex Hull on Inputs is a bound around the training data. This bound can be considered in the optimization, so that optimization results stay inside the range of the training data.
The Configure Convex Hull on Inputs window contains the following elements:
All pairwise convex 2D-Hulls checkbox
If activated (default), 2D hulls for all input pairs are used. The Show button next to the checkbox opens a 
scatter plot window that shows all pairwise 2D hulls.
Table area
This area allows the specification of user-defined hulls.
