Vertex adjacencies in the set covering polyhedron
(Elsevier Science, 2017-02)
We describe the adjacency of vertices of the (unbounded version of the) set covering polyhedron, in a similar way to the description given by Chvátal for the stable set polytope. We find a sufficient condition for adjacency, ...

On the Chvátal-rank of facets for the set covering polyhedron of circular matrices
(Elsevier, 2018)
We study minor related row family inequalities for the set covering polyhedron of circular matrices. We address the issue of generating these inequalities via the Chvátal-Gomory procedure and establish a general upper bound ...
Addendum to “Vertex adjacencies in the set covering polyhedron” [Discrete Appl. Math. 218 (2017) 40–56]
(Elsevier Science, 2018-07)
We study the relationship between the vertices of an up-monotone polyhedron R and those of the polytope P obtained by truncating R with the unit hypercube. When R has binary vertices, we characterize the vertices of P in ...
Some advances on the set covering polyhedron of circulant matrices
(Elsevier Science, 2014-03)
Studying the set covering polyhedron of consecutive ones circulant matrices, Argiroffo and Bianchi found a class of facet defining inequalities, induced by a particular family of circulant minors. In this work we extend ...

Ensino da geometria espacial construindo superfícies poliédricas com dobraduras
(Universidade Federal de Santa MariaBrasilUFSMCentro de Ciências Naturais e Exatas, 2016-05-20)
This work presents a differentiated proposal, from the one that we are used to, teaching geometry space. The class was applied in the group of third year in a State School of Rio Grande do Sul high school, name Marquês of ...
