Member Function Documentation

virtual bool Ipopt::ConvergenceCheck::InitializeImpl	(	const OptionsList &	options,
		const std::string &	prefix
	)			[pure virtual]

overloaded from AlgorithmStrategyObject

Implements Ipopt::AlgorithmStrategyObject.

Implemented in Ipopt::OptimalityErrorConvergenceCheck, and Ipopt::RestoFilterConvergenceCheck.

virtual ConvergenceStatus Ipopt::ConvergenceCheck::CheckConvergence

(

bool

call_intermediate_callback = true

)

[pure virtual]

Pure virtual method for performing the convergence test.

If call_intermediate_callback is true, the user callback method in the NLP should be called in order to see if the user requests an early termination.

Implemented in Ipopt::OptimalityErrorConvergenceCheck, and Ipopt::RestoFilterConvergenceCheck.

virtual bool Ipopt::ConvergenceCheck::CurrentIsAcceptable

(

)

[pure virtual]

Method for testing if the current iterate is considered to satisfy the "accptable level" of accuracy.

The idea is that if the desired convergence tolerance cannot be achieved, the algorithm might stop after a number of acceptable points have been encountered.

Implemented in Ipopt::OptimalityErrorConvergenceCheck.

void Ipopt::ConvergenceCheck::operator=

(

const ConvergenceCheck &

)

[private]

Overloaded Equals Operator.

Reimplemented from Ipopt::AlgorithmStrategyObject.

Reimplemented in Ipopt::OptimalityErrorConvergenceCheck, and Ipopt::RestoFilterConvergenceCheck.
