Description

A design variable whose values come from a specified set of admissible reals. The details of how to specify this discrete variable are located on the discrete_variables page.

Examples

Two continuous, restricted variables whose values will be selected from the following sets during the search for an optimal design. $y1 \in \{0.25,1.25, 2.25, 3.25, 4.25\}$, $y2 \in \{0,5\}$
