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" (1998).
