Regularity of Collections of Sets and Convergence of Inexact Alternating Projections
Alexander Y. Kruger, Nguyen Hieu Thao · Journal of convex analysis · 2016
We study the usage of regularity properties of collections of sets in convergence analysis of alternating projection methods for solving feasibility problems. Several equivalent characterizations of these properties are provided. Two settings of inexact alternating projections are considered and the corresponding convergence estimates are established and discussed.
