Computer science description: A simple criterion is proposed to improve suboptimal coordinate-convex policies in Call Admission Control problems with nonlinearly constrained feasibility regions. To test the criterion, numerical simulation results are given. Finally, some structural properties of the optimal coordinate-convex policies are proven, which do not depend on a complete knowledge of the nonlinear boundary of the feasibility region. date: 2010 type: Conference or Workshop Item type: PeerReviewed identifier: Gnecco, Giorgio and Cello, Marco and Sanguineti, Marcello On call admission control with nonlinearly constrained feasibility regions.
