The merit function by Tapia and Argaez

## Specification

Alias: none

Argument(s): none

## Description

The "argaez_tapia" merit function can be classified as a modified augmented Lagrangian function. The augmented Lagrangian is modified by adding to its penalty term a potential reduction function to handle the perturbed complementarity condition. The cost per linesearch iteration is one function evaluation. For more information, see [83].

If the function evaluation is expensive or noisy, set the `merit_function` to "argaez_tapia" or "van_shanno".
