Constructor Detail

Himmelblau

public Himmelblau()

Create an instance of the Himmelblau function. The initial domain is set to R(-6.0, 6.0)^2

Method Detail

getClone

public Himmelblau 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.

See Also:

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 vector)

Evaluate the function and return the result of the evaluation.

Specified by:

evaluate in class ContinuousFunction

Parameters:

vector - The Vector containing the two dimensional data.

Returns:

The value of the Himmalblau function with vector containing the function input.
