Method Detail

optimize

public void optimize()

Perform the optimization.

Specified by:

optimize in interface IOptimizer

Specified by:

optimize in class AbstractOptimizer

Returns:

true if the optimization was successfull, false otherwise.

minosAnalysis

public void minosAnalysis()

setFunction

public void setFunction(hep.aida.IFunction function)

Description copied from class: AbstractOptimizer

Set the IFunction to be optimized. When setting a function the current configuration is reset.

Specified by:

setFunction in interface IOptimizer

Overrides:

setFunction in class AbstractOptimizer

Parameters:

function - The IFunction to be optimized.

Returns:

true if the IFunction is set succesfully, false otherwise.

commands

protected MinuitCommands commands()

canCalculateContours

public boolean canCalculateContours()

Description copied from interface: IOptimizer

Check if this IOptimizer can calculate contours.

Specified by:

canCalculateContours in interface IOptimizer

Overrides:

canCalculateContours in class AbstractOptimizer

calculateContour

public double[][] calculateContour(String parName1,
                                   String parName2,
