Detailed Description
Convergence check for the restoration phase as called by the filter.
This inherits from the OptimalityErrorConvergenceCheck so that the method for the regular optimality error convergence criterion can be checked as well. In addition, this convergence check returns the CONVERGED message, if the current iteration is acceptable to the original filter.
Since this object needs to know about the original NLP, it also inherits from RestoProblemCoupler, so that the restoration phase object can call the SetObjs method to set the corresponding pointers before the Initilize for the restoration phase algorithm is called.

Member Function Documentation
| void Ipopt::RestoFilterConvergenceCheck::SetOrigFilterLSAcceptor | ( | const FilterLSAcceptor & | orig_filter_ls_acceptor | ) |
Set the object for the original filter line search.
Here, filter_line_search must be the same strategy object to which the restoration phase object with this object is given. This method must be called to finish the definition of the algorithm, before Initialize is called.

bool Ipopt::RestoFilterConvergenceCheck::first_resto_iter_ [private] |
Flag indicating that this is the first call.
We don't want to leave the restoration phase without taking at least one step, so this flag is used to ensure this.
Definition at line 90 of file IpRestoFilterConvCheck.hpp.
Counter for successive iterations in restoration phase.
Definition at line 93 of file IpRestoFilterConvCheck.hpp.
Strategy object for the filter line search method for the original NLP.
CAREFUL: We must not hold on to this object with a SmartPtr, because have otherwise circular references that prevent the destructor of the line search object to be called!
