Member Function Documentation

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

Initialize method - overloaded from AlgorithmStrategyObject.

Implements Ipopt::AlgorithmStrategyObject.

Implemented in Ipopt::LoqoMuOracle, Ipopt::ProbingMuOracle, and Ipopt::QualityFunctionMuOracle.

virtual bool Ipopt::MuOracle::CalculateMu	(	Number	mu_min,
		Number	mu_max,
		Number &	new_mu
	)			`[pure virtual]`

Method for computing the value of the barrier parameter that could be used in the current iteration.

Here, mu_min and mu_max are the lower and upper bounds on acceptable values for the barrier parameter. The new value of mu is returned in new_mu, and the method returns false if a new value could not be determined (e.g., because the linear system could not be solved for a predictor step).

Implemented in Ipopt::LoqoMuOracle, Ipopt::ProbingMuOracle, and Ipopt::QualityFunctionMuOracle.

void Ipopt::MuOracle::operator= ( const MuOracle & ) [private]

Overloaded Equals Operator.

Reimplemented from Ipopt::AlgorithmStrategyObject.

Reimplemented in Ipopt::LoqoMuOracle, Ipopt::ProbingMuOracle, and Ipopt::QualityFunctionMuOracle.
