The purpose of this work is to prove results concerning the duality theory and to give detailed study on the augmented Lagrangian algorithms and \(\varepsilon\)-proximal penalty method which are considered, today, as the most strong algorithms to solve nonlinear differentiable and nondifferentiable problems of optimization. We give an algorithm of primal-dual type, where we show that sequences \(\left\{\lambda^k\right\}_k\) and \(\left\{x^k\right\}_k\) generated by this algorithm converge globally, with at least the Slater condition, to \(\bar{\lambda}\) and \(\bar{x}\). Numerical simulations are given.
