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.
