Default Compiler Generated Methods

(Hidden to avoid implicit creation/calling).

These methods are not implemented and we do not want the compiler to implement them for us, so we declare them private and do not define them. This ensures that they will not be implicitly created/called.



 InexactNewtonNormalStep ()
 Default onstructor.
 InexactNewtonNormalStep (const InexactNewtonNormalStep &)
 Copy Constructor.
void operator= (const InexactNewtonNormalStep &)
 Overloaded Equals Operator.

Member Function Documentation

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