Resumo

Nesta nota, estamos interessados em resolver o problema de minimização com restrições de igualdade, podendo haver regiões não convexas. Para resolver este problema, consideramos o algoritmo primal-dual estudado por Armand e Omheni. Mas, em nossa abordagem, consideramos a função Pseudo-Huber para o caso de restrições de igualdade, e não a função de penalidade quadrática.

Abstract

In this note, we are interested in solving the minimization problem with equality constraints, with non-convexity assumptions. To solve this problem, we consider the primal-dual algorithm that was studied by Armand and Omheni. But in our approach, we consider the Pseudo-Huber function for the case of equality constraints, and not the quadratic penalty function.

Keywords: Non-convex optimization, Augmented Lagrangian methods, Equality-constrained minimization
