Method Detail

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.

setMaxIterations

public void setMaxIterations(int iterations)

Description copied from class: AbstractOptimizerConfiguration

Set the maximum number of iterations to be performed in the optimization procedure. If the optimizer did not converge before maxIter iterations the optimization will stop.

Specified by:

setMaxIterations in interface IOptimizerConfiguration

Overrides:

setMaxIterations in class AbstractOptimizerConfiguration

Parameters:

iterations - The maximum number of iterations.

maxIterations

public int maxIterations()

Description copied from class: AbstractOptimizerConfiguration

Get the maximum number of iterations allowed before exiting the optimization procedure.

Specified by:

maxIterations in interface IOptimizerConfiguration

Overrides:

maxIterations in class AbstractOptimizerConfiguration

Returns:

The maximum number of iterations.

setUseFunctionGradient

public void setUseFunctionGradient(boolean useFG)

Description copied from class: AbstractOptimizerConfiguration

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:

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

setStrategy

public void setStrategy(int strategy)

Description copied from class: AbstractOptimizerConfiguration

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

Specified by:

setStrategy in interface IOptimizerConfiguration

Overrides:

setStrategy in class AbstractOptimizerConfiguration

Parameters:

strategy - The strategy.

strategy

public int strategy()

Description copied from class: AbstractOptimizerConfiguration

Get the strategy used by the optimizer in the optimization procedure.

Specified by:

strategy in interface IOptimizerConfiguration

Overrides:

strategy in class AbstractOptimizerConfiguration

Returns:

The strategy.

setUseFunctionHessian

public void setUseFunctionHessian(boolean useHessian)

Description copied from class: AbstractOptimizerConfiguration

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

Specified by:

setUseFunctionHessian in interface IOptimizerConfiguration

Overrides:

setUseFunctionHessian in class AbstractOptimizerConfiguration

Parameters:

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

setPrecision

public void setPrecision(double precision)

Description copied from class: AbstractOptimizerConfiguration

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.
