Abstract

The basic problem considered in this paper may be stated as follows: find an N-point exact design measure N ? which maximizes the determinant of the information matrix of a given response function f(x), where x is an n-component vector of non-stochastic variables efined in a space of trial X ? . The combinatorial algorithm introduced in the paper reaches the global D-optimal design quite rapidly and a comparison against the variance exchange algorithm is indicated.
