Member Function Documentation

◆ InitializeImpl()

virtual bool Ipopt::StdStepCalculator::InitializeImpl ( const OptionsList options,
const std::string &  prefix 

Implementation of the initialization method that has to be overloaded by for each derived class.

Reimplemented from Ipopt::SensitivityStepCalculator.

◆ Step()

virtual bool Ipopt::StdStepCalculator::Step ( DenseVector delta_u,
IteratesVector sol 

This is the main algorithmic function of this class.

It calculates a step using its SchurDriver, checks bounds, and returns it

Implements Ipopt::SensitivityStepCalculator.

◆ BoundCheck()

bool Ipopt::StdStepCalculator::BoundCheck ( IteratesVector sol,
std::vector< Index > &  x_bound_violations_idx,
std::vector< Number > &  x_bound_violations_du 

◆ GetSensitivityVector()

virtual SmartPtr<IteratesVector> Ipopt::StdStepCalculator::GetSensitivityVector ( void  )

return the sensitivity vector

Implements Ipopt::SensitivityStepCalculator.
