Member Function Documentation

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

overloaded from AlgorithmStrategyObject

Implements Ipopt::AlgorithmStrategyObject.

virtual bool Ipopt::InexactNewtonNormalStep::ComputeNewtonNormalStep	(	Vector &	newton_x,
		Vector &	newton_s
	)			[virtual]

Method for computing the normal step.

The computed step is returned as normal_x and normal_s, for the x and s variables, respectively. These quantities are not in the original space, but in the space scaled by the slacks. If the step cannot be computed, this method returns false.
