Abstract

Let Mm,n(0, 1) be the set of m times n (0, 1)-matrices and G(m, n) = maxlcubdet WTW| WMm,n(0, 1)rcub. A matrix WMm,n(0, 1) with det WTW = G(m, n) is called D-optimal. Here we determine G(m, 10) for m large. Furthermore, we show that D-optimal examples are unique up to the action of a group.
Keywords: D-optimal design; weighing design; threshold partition
