%description
Provides computational tools to generate efficient blocked and unblocked
fractional factorial designs for two-level and three-level factors using
the generalized Minimum Aberration (MA) criterion and related optimization
algorithms. Methodological foundations include the general theory of
minimum aberration as described by Cheng and Tang (2005)
<doi:10.1214/009053604000001228>, and the catalogue of three-level regular
fractional factorial designs developed by Xu (2005)
<doi:10.1007/s00184-005-0408-x>. The main functions dol2() and dol3()
generate blocked two-level and three-level fractional factorial designs,
respectively, using beam search, optimization-based ranking, confounding
assessment, and structured output suitable for complete factorial
situations.
