The Cyclic Douglas-Rachford Algorithm with r-sets-Douglas-Rachford Operators

Optimization and Control 2018-07-18 v2

Abstract

The Douglas-Rachford (DR) algorithm is an iterative procedure that uses sequential reflections onto convex sets and which has become popular for convex feasibility problems. In this paper we propose a structural generalization that allows to use rr-sets-DR operators in a cyclic fashion. We prove convergence and present numerical illustrations of the potential advantage of such operators with r>2r>2 over the classical 22-sets-DR operators in a cyclic algorithm.
