Private Member Functions

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.

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

Private Attributes

Strategy objects

SmartPtr< PDSystemSolverpd_solver_
Algorithmic parameters

bool fast_step_computation_
 Flag indicating that we trust that the steps from the linear solver are very good and that we don't need any residual checks.
bool mehrotra_algorithm_
 Flag indicating if we want to do Mehrotras's algorithm.

Flag indicating that we trust that the steps from the linear solver are very good and that we don't need any residual checks.

Definition at line 81 of file IpPDSearchDirCalc.hpp.

Flag indicating if we want to do Mehrotras's algorithm.

This means that a number of options are ignored, or have to be set (or are automatically set) to certain values.
