Euler–frobenius Numbers and Rounding
We study the Euler–Frobenius numbers, a generalization of the Eulerian numbers, and the probability distribution obtained by normalizing them. This distribution can be obtained by rounding a sum of independent uniform random variables; this is more or less implicit in various results and we try to explain this and various connections to other areas of mathematics, such as spline theory. The mea...
متن کاملLP Relaxation , Rounding , and Randomized Rounding
1.1 Max-flow min-cut A flow network is a directed graph D = (V,E) with two distinguished vertices s and t called the source and the sink, respectively. Moreover, each arc (u, v) ∈ E has a certain capacity c(u, v) ≥ 0 assigned to it. Let X be a proper non-empty subset of V . Let X̄ := V −X , then the pair (X, X̄) forms a partition of V , called a cut of D. The set of arcs of D going from X to X̄ is...
متن کاملGeometric rounding: a dependent randomized rounding scheme
We develop a new dependent randomized rounding method for approximation of a number of optimization problems with integral assignment constraints. The core of the method is a simple, intuitive, and computationally efficient geometric rounding that simultaneously rounds multiple points in a multi-dimensional simplex to its vertices. Using this method we obtain in a systematic way known as well a...
متن کاملRelative Rounding
Solid models may be rounded through filleting or blending operations. In 3D, the faces created by rounding are portions of the canal surface bounding the region swept by a ball (of constant or varying radius) as the ball rolls on (i.e., moves while maintaining tangential contact with) the two solids. Procedural or algebraic definitions of how the radius of the ball varies as it rolls may prove ...
متن کاملRounding up
All of the isotopes of radon are radioactive, which means that its chemistry has not been studied as widely as its smaller and more stable cousin, xenon. In particular, the supramolecular chemistry of xenon has been the focus of much research, and it is known that individual xenon atoms can bind inside hollow cage-like molecules with relatively high affinities. Although radon is incorporated in...
