## Protected Attributes
Algorithmic parameters
Index | max_iterations_
| Maximal number of iterations.
Number | dual_inf_tol_

Number | acceptable_tol_
| Acceptable tolerance for the problem to terminate earlier if algorithm seems stuck or cycling.
Number | acceptable_dual_inf_tol_

Number | acceptable_constr_viol_tol_
| Acceptable tolerance on unscaled constraint violation.
Number | acceptable_compl_inf_tol_
| Acceptable tolerance on unscaled complementarity.
Number | diverging_iterates_tol_

## 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.
| OptimalityErrorConvergenceCheck (const OptimalityErrorConvergenceCheck &)
| Copy Constructor.
void | operator= (const OptimalityErrorConvergenceCheck &)
| Overloaded Equals Operator.
## Private Attributes
Index | acceptable_counter_
| Counter for successive iterations in which acceptability criteria are met.
