%O 24th European Conference on operational research %P 105 %T On Call Admission Control with Nonlinearly Constrained Feasibility Regions %C Lisbon, Portugal %D 2010 %L eprints1773 %X 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. %A Marco Cello %A Giorgio Gnecco %A Mario Marchese %A Marcello Sanguineti
