Abstract: We examine two coefficient adjustment methods proposed in the literature, and we show by example that the second is not valid. We provide a modified approach that subsumes both methods, generalizing the first and correcting the second.

Keywords: Integer programming, theory: coefficient adjustment using special ordered sets; cutting planes; continuous relaxation (search for similar items in EconPapers)
