Member Function Documentation

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

Initialize method - overloaded from AlgorithmStrategyObject.

Implements AlgorithmStrategyObject.

Implemented in LoqoMuOracle, ProbingMuOracle, and QualityFunctionMuOracle.

virtual bool 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 LoqoMuOracle, ProbingMuOracle, and QualityFunctionMuOracle.
