摘      要:

       Nested orthogonal arrays (NOAs) are widely used in computer experiments with qualitative and quantitative factors, multi-fidelity experiments, cross-validation, and stochastic optimization. They are practical for constructing space-filling designs when combining two experiments of varying accuracy. This paper presents new NOAs using the product construction method, including symmetric saturated and asymmetric arrays.
