Constant Field Values

LOW_CALL_STRATEGY

public static final int LOW_CALL_STRATEGY

The kind of strategies available in Uncmin. With the LOW_CALL_STRATEGY (default) the Hessian is evaluated by secant update rather than analytically or by finite difference. The option with "_CHECK" enables some authomatic checks.

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.

setStrategy

public void setStrategy(int strategy)

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.

setPrecision

public void setPrecision(double precision)

Description copied from class: AbstractOptimizerConfiguration
