# Constrained space filling - Reasonable Design Space

It’s not uncommon to have optimization problems where simply providing individual bounds for every variable is insufficient, for example geometrical problems where a sum of thicknesses may not exceed a given value. Such infeasible experiments can be avoided in the sampling (DOE), while maintaining a good space filling design. Consider an LS-OPT project with the following variable design: And let’s say we constantly need the variable
Selecting This is the point sampling we get after running LS-OPT with these settings:
Here’s a more involved example with two constraints, |
