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>.
