Original Kurzfassung:
In this paper, we study the problem of D-optimal experimental design under two linear constraints, which can be interpreted as simultaneous restrictions on the size and on the total cost of the experiment. For computing a size-and-cost constrained approximate D-optimal design, we propose a ?barycentric? algorithm with sequential removal of redundant design points. We analytically prove convergence results about the barycentric algorithm and numerically demonstrate its favourable properties compared to competing methods.
