Direct Known Subclasses:

ConstrainedMultiMetricDiviner

public class ConstrainedEIDiviner
extends ConstrainedImprovementDiviner

Constrained version of the EIDiviner. For now, uses the product of expected improvement on the objective and the probability of improving the feasibility.

Method Detail

init

public void init()

Description copied from class: BasicScalarFunction

Initialization method.

Specified by:

init in interface BoundConstrainedDiviner

Specified by:

init in interface ScalarFunction

Overrides:

init in class BasicBoundConstrainedDiviner

quickCompute

public double quickCompute(double[] x)

Description copied from class: BasicScalarFunction

Compute method without dimension checking. All subclasses must implement this method: it is the core method that defines the function.

Specified by:

quickCompute in interface ScalarFunction

Specified by:

quickCompute in class BasicScalarFunction

Parameters:

x - the given input.

Returns:

the output corresponding to the given input.

makeObjectiveDiviner

protected ImprovementDiviner makeObjectiveDiviner()

Description copied from class: ConstrainedImprovementDiviner

Constructs and returns an diviner for the objective function.

Specified by:

makeObjectiveDiviner in class ConstrainedImprovementDiviner

Returns:

the diviner for the objective function.
