Constructor Detail

HyperEllipsoid

public HyperEllipsoid()
Creates a new instance of HyperEllipsoid. Default domain is set to R(-5.12, 5.12)^30

Method Detail

getClone

public HyperEllipsoid 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 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.
