maximin_cplus: Maximin criterion

Description

Compute the maximin criterion (also called mindist). This function uses a C++ implementation of the function mindist from package DiceDesign.

Usage

maximin_cplus(design)

Value

A real number equal to the value of the maximin criterion for the design.

Arguments

design

a matrix representing the design of experiments in the unit cube [0,1]\(^d\). If this last condition is not fulfilled, a transformation into [0,1]\(^{d}\) is applied before the computation of the criteria.

Details

The maximin criterion is defined by: $$maximin= \min_{x_{i}\in X} \left( \gamma_{i} \right)$$ where \(\gamma_{i}\) is the minimal distance between the point \(x_{i}\) and the other points \(x_{k}\) of the design.

A higher value corresponds to a more regular scaterring of design points.
