SpaceFillingMinDist

class SpaceFillingMinDist(*args)

Space filling minimal distance criterion.

Notes

Compute the criterion based on the minimal distance of sample points:

\begin{equation*} \phi_{min}(X) = \min_{i \neq j} ||x^{(i)} - x^{(j)}|| \end{equation*}

Methods

evaluate(sample)

Compute the MinDist criterion for a specific design.

getClassName()

Accessor to the object's name.

getId()

Accessor to the object's id.

getName()

Accessor to the object's name.

getShadowedId()

Accessor to the object's shadowed id.

getVisibility()

Accessor to the object's visibility state.

hasName()

Test if the object is named.

hasVisibleName()

Test if the object has a distinguishable name.

isMinimizationProblem()

Minimization flag accessor.

perturbLHS(oldDesign, oldCriterion, row1, ...)

Elementary perturbation.

setName(name)

Accessor to the object's name.

setShadowedId(id)

Accessor to the object's shadowed id.

setVisibility(visible)

Accessor to the object's visibility state.
__init__(*args)
evaluate(sample)

Compute the MinDist criterion for a specific design.

Parameters:
designSample or 2-d array like

The design

Returns:
critfloat

The MinDist criterion

Examples

>>> import openturns as ot
>>> # Build an LHS using openturns class
>>> lhs = ot.LHSExperiment(ot.Uniform(), 100)
>>> design = lhs.generate()
>>> # Compute the MinDist criterion
>>> crit = ot.SpaceFillingMinDist().evaluate(design)
