Outline of Final Research Achievements

In this research, we investigate the diameter of polyhedra. In particular, we improved the current best upper bound on the diameter of a polyhedron in terms of two parameters: dimension and number of facets of the given polyhedron. Finding a good upper bound on the diameter of a polyhedron is an outstanding open problem in the area of polyhedral combinatorics. We devised (i) a computer-assisted proof method for deriving numerically improved upper bounds and (ii) new proof techniques for deriving theoretically improved upper bounds especially for high-dimensional polyhedra.
