In this paper we explore the behaviour of the algorithm when the inclusion problem has no solution. We present a new formula to define the normal solutions using the forward-backward operator. We also provide a formula for the range of the displacement map of the forward-backward operator. Several examples illustrate our theory.", "revisions": [ { "version": "v1", "updated": "2016-08-07T16:44:52.000Z" } ], "analyses": { "subjects": [ "47H09", "49M27", "65K10", "47H05", "47H14", "49M29", "49N19" ], "keywords": [ "normal problem", "forward-backward algorithm", "forward-backward operator", "examples illustrate", "popular method" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
