The disjunctive procedure and blocker duality
(Elsevier Science, 2002-09)
In this paper we relate two rather different branches of polyhedral theory in linear optimization problems: the blocking type polyhedra and the disjunctive procedure of Balas et al. For this purpose, we define a disjunctive ...
On the minimum of a positive polynomial over the standard simplex
(Academic Press Ltd - Elsevier Science Ltd, 2010-04)
We present a new positive lower bound for the minimum value taken by a polynomial P with integer coefficients in k variables over the standard simplex of Rk, assuming that P is positive on the simplex. This bound depends ...

A mixed discretization of elliptic problems on polyhedra using anisotropic hybrid meshes
(Springer, 2019-06)
A Virtual Element Method is introduced for the mixed approximation of a simple model problem for the Laplace operator on a polyhedron. The method is fully analysed when the meshes are made up of triangular right prisms, ...
Cálculo de conjuntos invariantes controlados robustos com complexidade fixa usando otimização bilinear
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ENGENHARIA ELÉTRICA E DE COMPUTAÇÃO, 2020-11-06)
In this work, a methodology for the computation of robust controlled invariant polyhedra of fixed complexity, based on bilinear optimization, is proposed for discrete-time
linear systems, subject to constraints on the ...
Polyhedrization of an arbitrary 3D point set
(Elsevier Science Sa, 2003-12)
The extended Delaunay tessellation (EDT) is presented in this paper as the unique partition of a node set into polyhedral regions defined by nodes lying on the nearby Voronoï spheres. Until recently, all the FEM mesh ...
