public class EIDiviner
extends ImprovementDiviner

Implements an expected improvement BoundConstrainedDiviner. Note that this implementation treats the uncertainty estimate from its ApproxModel as if it were a Gaussian Process.

Method Detail

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.
