Constructor Detail

Foxholes

public Foxholes()

Create an instance of Foxholes. The default domain is set to R(-65.536,65.536)^2.

Method Detail

getClone

public Foxholes getClone()

Create a cloned copy of the current object and return it. In general the created copy will be a deep copy of the provided instance. As a result this operation an be quite expensive if used incorrectly.

Specified by:

getClone in interface Cloneable

Specified by:

getClone in class ContinuousFunction

Returns:

An exact clone of the current object instance.

Object.clone()

getMinimum

public Object getMinimum()

Accessor for the function minimum. This is the minimum value of the function in the given domain.

Overrides:

getMinimum in class ContinuousFunction

Returns:

The minimum function value.

evaluate

public double evaluate(Vector x)

Evaluate the function with the given Vector as input.

Specified by:

evaluate in class ContinuousFunction

Parameters:

x - The input Vector.

Returns:

The value of the evaluation.
