 Method for checking progress with original globalization mechanism.
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.

Algorithmic parameters
Number kappa_resto_
 Fraction of required reduction in infeasibility before problem is considered to be solved.

Number orig_constr_viol_tol_
 Constraint violation tolerance for original algorithm.

Detailed Description

Convergence check for the restoration phase.

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 globalization scheme.

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.
