          net.sourceforge.cilib.functions.continuous.ContinuousStep

All Implemented Interfaces:

Serializable, Cloneable

public class ContinuousStep
extends ContinuousFunction

The continuous Step function. It is the same as the normal step function, however, it is continuous and not discrete.

The default domain of the function is defined to be R(-100.0, 100.0)^30

Constructor Detail

ContinuousStep

public ContinuousStep()

Creates a new instance of Step.

Method Detail

getClone

public ContinuousStep 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()

Get the defined minimum of the Function. The minimum is defined to be the value of 0.0.

Overrides:

getMinimum in class ContinuousFunction

Returns:

An Object containing the value 0.0.

getMaximum

public Object getMaximum()

Get the defined maximum of the Function. The maximum value is defined to be the value of 55.0.

Overrides:

getMaximum in class ContinuousFunction

Returns:

An Object containing the value 55.0.

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.
