Computer science description: Two criteria are proposed to characterize and improve suboptimal coordinate-convex (c.c.) policies in Call Admission Control (CAC) problems with nonlinearly-constrained feasibility regions. Then, a structural property of the optimal c.c. policies is derived. This is expressed in terms of constraints on the relative positions of successive corner points. publisher: IEEE date: 2011 type: Article type: PeerReviewed identifier: Cello, Marco and Gnecco, Giorgio and Marchese, Mario and Sanguineti, Marcello CAC with Nonlinearly-Constrained Feasibility Regions.
