method of approximation
51Born-Oppenheimer approximation — In quantum chemistry, the computation of the energy and wavefunction of an average size molecule is a formidable task that is alleviated by the Born Oppenheimer (BO) approximation. For instance the benzene molecule consists of 12 nuclei and 42… …
52GF method — Wilson s GF method, sometimes referred to as FG method, is a classical mechanical method to obtain certain internal coordinates fora vibrating semi rigid molecule, the so called normal coordinates Q k. Normal coordinates decouple the classical… …
53Dixon's factorization method — In number theory, Dixon s factorization method (also Dixon s random squares method[1] or Dixon s algorithm) is a general purpose integer factorization algorithm; it is the prototypical factor base method, and the only factor base method for which …
54Durand-Kerner method — In numerical analysis, the Durand ndash;Kerner method (established 1960 ndash;66) or method of Weierstrass (established 1859 ndash;91) is a root finding algorithm for solving polynomial equations. In other words, the method can be used to solve… …
55Coopmans Approximation — The Coopmans Approximation is a method for approximating a fractional order integrator in a continuous process with constant space complexity. The most correct and accurate methods for calculating the fractional integral require a record of all… …
56Predictor-corrector method — In mathematics, particularly numerical analysis, a predictor corrector method is an algorithm that proceeds in two steps. First, the prediction step calculates a rough approximation of the desired quantity. Second, the corrector step refines the… …
57Ritz method — In physics, the Ritz method is a variational method named after Walter Ritz.In quantum mechanics, a system of particles can be described in terms of an energy functional or Hamiltonian, which will measure the energy of any proposed configuration… …
58Ridders' method — In numerical analysis, Ridders method is a root finding algorithm based on the false position method and the use of an exponential function to successively approximate a root of a function f .Ridders method is simpler than Brent s method but… …
59Successive approximation ADC — Successive Approximation redirects here. For behaviorist B.F. Skinner s method of guiding learned behavior, see Shaping (psychology). A successive approximation ADC is a type of analog to digital converter that converts a continuous analog… …
60Stirling's approximation — In mathematics, Stirling s approximation (or Stirling s formula) is an approximation for large factorials. It is named in honour of James Stirling.The formula is written as:n! approx sqrt{2pi n}, left(frac{n}{e} ight)^{n}.Roughly, this means that …
