A comparative analysis of the convergence regions for different parallel affine projection algortihms

Abstract

This paper analysis the dimension and the shape of conver-
gence regions of three algorithms used to solve the convex feasibility prob-
lem in bidimensional space: the Parallel Projection Method (PPM), the
classical Extrapolated Method of Parallel Projections (EMOPP) and a mod-
ied version of EMOPP.
