The polyhedral model (also called the polytope method) is a mathematical framework for programs that perform large numbers of operations -- too large to be explicitly enumerated -- thereby requiring a compact representation. Nested loop programs are the typical, but not the only example, and the most … See more Consider the following example written in C: The essential problem with this code is that each iteration of the inner loop on a[i][j] requires that the previous iteration's result, a[i][j - 1], be … See more The following C code implements a form of error-distribution dithering similar to Floyd–Steinberg dithering, but modified for pedagogical … See more • "The basic polytope method", tutorial by Martin Griebl containing diagrams of the pseudocode example above • "Code Generation in the Polytope Model" See more • Frameworks supporting the polyhedral model • Loop nest optimization • Loop optimization See more WebPOLYHEDRAL METHODS IN DISCRETE OPTIMIZATION 3 Since CG inequalities are valid for S, we have conv(S) µ E(P).It turns out that a finite number of „ is sufficient to describe …
WebExtreme rays. Let C ⊆ R n be a polyhedral cone. A nonzero d ∈ C is an extreme ray of C if there do not exist linearly independent u, v ∈ C and positive scalars λ and γ such that d = λ u + γ v . Note that if d is an extreme ray, then λ d is also an extreme ray for all λ > 0 . We say that two extreme rays are equivalent if one is a ...

WebWe present a preliminary method to generate polyhedral meshes of general non-manifold domains. The method is based on computing the dual of a general tetrahedral mesh. The resulting mesh respects the topology of the domain to the same extent as the input mesh. If the input tetrahedral mesh is Delaunay and well-centered, the resulting mesh is a ...
