Selective Random Search for Optimal Experiment Designs

The most time consuming task in numerical search for optimum experiment design is in finding (by multidimensional global maximization) candidate points to be entered to a current design. To overcome this difficulty it is proposed to use a selective random search. The key idea is to use the probability distribution proportional to the prediction variance of the present design as the density of random search. In each iteration of the proposed algorithm additional optimization of the current design weights is performed.
