Efficient space-filling and near-orthogonality sequential Latin hypercube for computer experiments

In this paper, a general and efficient method for constructing LHDs possessing favorable characteristics of orthogonality and better computational efficiency is first proposed. Next, a sequentially enlarging strategy is derived based on the initial design. During the enlarging process, optimization of space-filling property is carried out, and a near-orthogonal space-filling augmented LHD is subsequently obtained. The enlarging process is...
