faces is a
polytopal body...

there pivot rules which lead to polynomial-time
simplex variants? Do all
polytopal graphs have
polynomially bounded diameter?
These questions relate to the...

polyhedral complex is a set of
polyhedra in a real
vector space that fit
together in a
specific way.
Polyhedral complexes generalize...
