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


Four integer variables whose values will be selected from the following sets during the search for an optimal design. $y1 \in \{0,1\}$, $y2 \in \{0, 1\}$, $y3 \in \{0,5\}$ and $y4 \in \{10, 15, 20, 23\}$.
