%description
Constructs mixed-level and regular fractional factorial designs using
coordinate-exchange optimization and automatic generator search. Design
quality is evaluated with J2 and balance (H-hat) criteria, alias
structures are computed via correlation-based chaining, and deterministic
trend-free run orders can be produced following Coster (1993)
<doi:10.1214/aos/1176349410>. Mixed-level design construction follows the
NONBPA approach of Pantoja-Pacheco et al. (2021)
<doi:10.3390/math9131455>. Regular fraction identification follows Guo,
Simpson and Pignatiello (2007) <doi:10.1080/00224065.2007.11917691>. Alias
structure computation follows Rios-Lira et al.(2021)
<doi:10.3390/math9233053>.
