Abstract

Motivated by the construction of supersaturated designs, we develop a class of algorithms called columnwise-pairwise exchange algorithms. They differ from the k-exchange algorithms in two respects: (1) They exchange columns instead of rows of the design matrix, and (2) they employ a pairwise adjustment in the search for a “better” column. The proposed algorithms perform very well in the construction of supersaturated designs both for a single criterion and for multiple criteria. They are also applicable to the construction of designs that are not supersaturated.
