A Modified Simplex Algorithm of D-Optimal Designs

摘要

In this paper, a new computer algorithm for generating D-optimal design was put forward by using the modified simplex iteration. On the basis of Evans's simplex algorithm, the negative measure and Fibonacci sequence were introduced into generating the new design point. With the multi-circulation method and symmetric theory, a modified simplex algorithm of D-optimal design is given. Through this new algorithm, the D-optimal designs result of multi-component mixture regression models with logarithmic term is given.
