A note on the optimality of resolvable block designs with unequal block sizes. (English) Zbl 0939.62077
Summary: \((M,S)\)-optimality is used in computer search algorithms as a quick way of filtering out inefficient designs. We show that it does not work well for resolvable designs with unequal block sizes. Instead we suggest the use of a criterion based on the dual design.
