Método do ponto proximal com distância de Bregman para problemas de minimização quase convexos

Abstract

In this work, we study the convergence of the proximal point method for solving a constrained minimization problem within the nonnegative orthant for quasiconvex functions. To this end, the Euclidian distance in the regularization term of the classic proximal point method is replaced by a map with nice similar properties such as a distance but not necessarily satisfying all the axioms of a distance. Such a map is the so called Bregman distance.
