Although this abstraction is simpler than other abstractions that were previously studied in the literature, the best upper bounds on the diameter of polyhedra continue to hold here. On the other hand, we show that this abstraction has its limits by providing a superlinear lower bound.convex geometrydisjoint coveringsHirsch conjecturepolyhedratext::conference output::conference proceedings::conference paper
