Detailed Description

Updates the penalty parameter for a merit function as: mu_k = max( mu_km1, min_mu ).

This class assumes the merit function iteration quantity supports the interfaces MeritFuncPenaltyParam and MeritFuncNLPDirecDeriv.

min_mu is computed by subclasses.

virtual bool MoochoPack::MeritFunc_PenaltyParamUpdateGuts_AddedStep::min_mu	(	NLPAlgoState &	s,
		value_type *	min_mu
	)		const [protected, pure virtual]

Override to determine the mininum value of mu the penalty parameter can take on.

Parameters:

s	[in] The rSQP state object to get at useful information.
min_mu	[out] If min_mu(...) returns true, then this is the mininum value mu can take on and still have descent in the merit function.

Returns:

Returns true if the penalty parameter should be updated or false if the previous mu_km1 should be used.

Implemented in MoochoPack::MeritFunc_PenaltyParamUpdateWithMult_AddedStep, and MoochoPack::MeritFunc_PenaltyParamUpdateMultFree_AddedStep.

virtual void MoochoPack::MeritFunc_PenaltyParamUpdateGuts_AddedStep::print_min_mu_step	(	std::ostream &	out,

	)		const [protected, pure virtual]

Override to print how min_mu calculated.

Implemented in MoochoPack::MeritFunc_PenaltyParamUpdateWithMult_AddedStep, and MoochoPack::MeritFunc_PenaltyParamUpdateMultFree_AddedStep.
