Random iterations of paracontraction maps and applications to feasibility problems
Edgar Matias, Majela Pentón Machado
In this paper, we consider the problem of finding an almost surely common fixed point of a family of paracontraction maps indexed on a probability space, which we refer to as the s…

Inexact proximal -subgradient methods for composite convex optimization problems
Reinier Díaz Millán, Majela Pentón Machado
We present two approximate versions of the proximal subgradient method for minimizing the sum of two convex functions (not necessarily differentiable). The algorithms involve, at e…
