Description

A design variable whose values come from a specified set of admissible integers. See Usage Notes for tips on specifying discrete set variables.

Examples

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 \(y4 \in \{10, 15, 20, 23\}\) .
