A method for obtaining efficient UE(s²)‐optimal two‐level supersaturated designs

Abstract

In this paper, we describe a method that can be used to obtain UE(s2)‐optimal two‐level supersaturated designs. A major advantage of the proposed approach is the information it provides on the correlation structure of the generated UE(s2)‐optimal supersaturated design and on the pairs of its orthogonal (or nearly orthogonal) columns. Therefore, it can be used to further distinguish between competitive UE(s2)‐optimal designs. Examples are given to illustrate the usefulness and the flexibility of the proposed method.
