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. date: 2011 date_type: published publication: IEEE Communications Letters volume: 15 number: 4 publisher: IEEE pagerange: 467-469 id_number: 10.1109/LCOMM.2011.030311.102228 refereed: TRUE issn: 1089-7798 official_url: http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=5734793&isnumber=5749432 citation: Cello, Marco and Gnecco, Giorgio and Marchese, Mario and Sanguineti, Marcello CAC with Nonlinearly-Constrained Feasibility Regions.
