Approximation — (lat.: proximus, „der Nächste“) ist zunächst ein Synonym für Näherung; der Begriff wird in der Mathematik allerdings noch präzisiert. Es gibt vor allem zwei Gründe in der Mathematik, Näherungen zu untersuchen: Einmal könnte das Objekt des… … Deutsch Wikipedia
Methods of computing square roots — There are several methods for calculating the principal square root of a nonnegative real number. For the square roots of a negative or complex number, see below. Contents 1 Rough estimation 2 Babylonian method 2.1 Example … Wikipedia
Approximation — An approximation (represented by the symbol ≈) is an inexact representation of something that is still close enough to be useful. Although approximation is most often applied to numbers, it is also frequently applied to such things as… … Wikipedia
Approximation diophantienne — En théorie des nombres, l approximation diophantienne, qui porte le nom de Diophante d Alexandrie, traite de l approximation des nombres réels par des nombres rationnels. La plus petite distance (au sens de la valeur absolue) entre le nombre réel … Wikipédia en Français
Approximation sigma — En mathématiques, l’approximation sigma, imaginée par Cornelius Lanczos, est une méthode de fenêtrage qui permet d ajuster une série de Fourier pour éliminer le phénomène de Gibbs qui pourrait survenir aux discontinuités. Principe Une… … Wikipédia en Français
Stochastic approximation — methods are a family of iterative stochastic optimization algorithms that attempt to find zeroes or extrema of functions which cannot be computed directly, but only estimated via noisy observations. The first, and prototypical, algorithms of this … Wikipedia
Muffin-tin approximation — Electronic structure methods Tight binding Nearly free electron model Hartree–Fock method Modern valence bond Generalized valence bond Møller–Plesset perturbation theory … Wikipedia
Ab initio quantum chemistry methods — are computational chemistry methods based on quantum chemistry.[1] The term ab initio was first used in quantum chemistry by Robert Parr and coworkers, including David Craig in a semiempirical study on the excited states of benzene.[2][3] The… … Wikipedia
Meshfree methods — are a particular class of numerical simulation algorithms for the simulation of physical phenomena. Traditional simulation algorithms relied on a grid or a mesh, meshfree methods in contrast use the geometry of the simulated object directly for… … Wikipedia
Monte Carlo methods for electron transport — The Monte Carlo method for electron transport is a semiclassical Monte Carlo(MC) approach of modeling semiconductor transport. Assuming the carrier motion consists of free flights interrupted by scattering mechanisms, a computer is utilized to… … Wikipedia
Runge–Kutta methods — In numerical analysis, the Runge–Kutta methods (pronounced IPA|/ˌʀuŋgeˈkuta/) are an important family of implicit and explicit iterative methods for the approximation of solutions of ordinary differential equations. These techniques were… … Wikipedia
