public Rosenbrock()

Default constructor.

Rosenbrock

public Rosenbrock(int inputDimension)

Constructs a Rosenbrock instance in the given number of dimensions.

Parameters:

inputDimension - the given input dimension.

Method Detail

init

public void init()

Description copied from class: BasicScalarFunction

Initialization method.

Specified by:

init in interface ScalarFunction

Overrides:

init in class VariableDomainScalarFunction

quickCompute

public double quickCompute(double[] x)

Description copied from class: BasicScalarFunction

Compute method without dimension checking. All subclasses must implement this method: it is the core method that defines the function.

Specified by:

quickCompute in interface ScalarFunction

Specified by:

quickCompute in class BasicScalarFunction

Parameters:

x - the given input.

Returns:

the output corresponding to the given input.

setInputDimension

public void setInputDimension(int inputDimension)

Description copied from class: VariableDomainScalarFunction

Sets the number of input dimensions.

Specified by:

setInputDimension in interface VariableInputDimension

Overrides:

setInputDimension in class VariableDomainScalarFunction

Parameters:

inputDimension - the given number of input dimensions.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
