virtual bool Ipopt::MuUpdate::InitializeImpl | ( | const OptionsList & | options, | |

) | [pure virtual] |
Initialize method - overloaded from AlgorithmStrategyObject.
Implements Ipopt::AlgorithmStrategyObject.
Implemented in Ipopt::AdaptiveMuUpdate, and Ipopt::MonotoneMuUpdate.
virtual bool Ipopt::MuUpdate::UpdateBarrierParameter | ( | ) | [pure virtual] |
Method for determining the barrier parameter for the next iteration.
A LineSearch object is passed, so that this method can call the Reset method in the LineSearch object, for example when then barrier parameter is changed. This method is also responsible for setting the fraction-to-the-boundary parameter tau. This method returns false if the update could not be performed and the algorithm should revert to an emergency fallback mechanism.
Implemented in Ipopt::AdaptiveMuUpdate, and Ipopt::MonotoneMuUpdate.
void Ipopt::MuUpdate::operator= | ( | const MuUpdate & | ) | [private] |
Overloaded Equals Operator.
Reimplemented from Ipopt::AlgorithmStrategyObject.
Reimplemented in Ipopt::AdaptiveMuUpdate, and Ipopt::MonotoneMuUpdate.
