Construction techniques for cubical complexes, odd cubical 4-polytopes, and prescribed dual manifolds
Alexander Schwartz, Guenter M. Ziegler
We provide a number of new construction techniques for cubical complexes and cubical polytopes, and thus for cubifications (hexahedral mesh generation). As an application we obtain…

The Simplex Algorithm in Dimension Three
Volker Kaibel, Rafael Mechtel, Micha Sharir +1
We investigate the worst-case behavior of the simplex algorithm on linear programs with three variables, that is, on 3-dimensional simple polytopes. Among the pivot rules that we c…
