Method Detail

setDefaults

protected void setDefaults()

setErrorDefinition

public void setErrorDefinition(int errorDefinition)

Tell the optmizer what kind of errors to calculate.

Specified by:

setErrorDefinition in interface IOptimizerConfiguration

Overrides:

setErrorDefinition in class AbstractOptimizerConfiguration

Parameters:

errorDefinition - The type of error to be calculated.

errorDefinition

public int errorDefinition()

Get the optimizer's error definition.

Specified by:

errorDefinition in interface IOptimizerConfiguration

Overrides:

errorDefinition in class AbstractOptimizerConfiguration

Returns:

The error definition.

setMethod

public void setMethod(String method)

Set the method to be used by the optimizer in the optimization procedure.

Specified by:

setMethod in interface IOptimizerConfiguration

Overrides:

setMethod in class AbstractOptimizerConfiguration

Parameters:

method - The method to be adapted.

setPrecision

public void setPrecision(double precision)

Set the precision required in the optimizer's calculations. The highest possible is the machine's precision.

Specified by:

setPrecision in interface IOptimizerConfiguration

Overrides:

setPrecision in class AbstractOptimizerConfiguration

Parameters:

precision - The precision.

Returns:

true if the precision was set succesfully, false otherwise.

setStrategy

public void setStrategy(int strategy)

Specified by:

setStrategy in interface IOptimizerConfiguration

Overrides:

setStrategy in class AbstractOptimizerConfiguration

Parameters:

strategy - The strategy.

setUseFunctionGradient

public void setUseFunctionGradient(boolean useFunctionGradient)

Specify if the optimizer has to use the gradient as provided by the IFunction.

Specified by:

setUseFunctionGradient in interface IOptimizerConfiguration

Overrides:

setUseFunctionGradient in class AbstractOptimizerConfiguration

Parameters:

useFunctionGradient - true if the Optimizer has to use the IFunction's calculation of the gradient, false otherwise.

Description copied from class: AbstractOptimizerConfiguration

Set the printout level.

Specified by:

setPrintLevel in interface IOptimizerConfiguration

Overrides:

setPrintLevel in class AbstractOptimizerConfiguration

Parameters:

printLevel - The printout level.

Returns:

true if the level was set succesfully, false otherwise.
