Constructor Detail

Bohachevsky3

public Bohachevsky3()

Creates a new instance of Bohachevsky2. Domain defaults to R(-100.0, 100)^2

Method Detail

getClone

public Bohachevsky3 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()

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.
