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)

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.

Value

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