categorical
Whether the set-valued variables are categorical or relaxable
Specification
Alias: None
Arguments: STRINGLIST
Description
A list of strings of length equal to the number of set (integer, string, or real) variables indicating whether they are strictly categorical, meaning may only take on values from the provided set, or relaxable, meaning may take on any integer or real value between the lowest and highest specified element. Valid categorical strings include ‘yes’, ‘no’, ‘true’, and ‘false’, or any abbreviation in [yYnNtTfF][.]*
Examples
Discrete_design_set variable, ‘rotor_blades’, can take on only integer values, 2, 4, or 7 by default. Since categorical is specified to be false, the integrality can be relaxed and ‘rotor_blades’ can take on any value between 2 and 7, e.g., 3, 6, or 5.5.
