A Dynamic Sampling Method for Kriging and Cokriging Surrogate Models

Abstract

In this paper we describe our gradient and Hessian enhanced Kriging surrogate model with dynamic sample point selection. We demonstrate the quality of the surrogate by comparison with higher-dimensional analytic test functions. We also apply the surrogate model to uncertainty quantification and robust optimization problems using inexpensive Monte-Carlo simulations. All applications benefit from the additional gradient and Hessian information as well as the dynamic sample point selection by requiring fewer function evaluations and overall less computational time.
