Abstract
A combinatorial structure called abstract polytope is introduced. It is shown that abstract polytopes are a subclass of pseudo-manifolds and include (combinatorially) simple convex polytopes as a special case.
The main objective is to determine the maximum diameter of abstract polytopes of dimension less than or equal to 5. Those results are relevant to the study of the efficiency of “vertex following” algorithms since the maximum diameter of d-dimensional polytopes with n facets represent, in a sense, the number of iterations required to solve the “worst” problem (with constraint set of d variables with n inequality constraints) using the “best” vertex following algorithm.
