Constructor Detail

Shir

public Shir()

Create an instance of the function. The domain is set to "R(0, 1)^30" by default.

Method Detail

getClone

public Shir 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()

getMaximum

public Object getMaximum()

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

Overrides:

getMaximum in class ContinuousFunction

Returns:

The maximum of the function.

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.
