Global Error Control In Adaptive Nordsieck Methods

The error estimators are derived for both consistent Nordsieck methods and quasi-consistent ones. In turn, this can impose a strong relation between the local and global errors of the numerical solution and allow the global error to be controlled effectively by a local error Comput. 25, 3–16 (2005).CrossRefMATHMathSciNetGoogle Scholar22.G.

In addition, adaptive numerical schemes are of special interest in computational practice because they are capable of computing numerical solutions satisfying this or that user’s requirements in automatic mode.

Appl. morefromWikipedia Estimator In statistics, an estimator is a rule for calculating an estimate of a given quantity based on observed data: thus the rule and its result (the estimate) are distinguished.

This makes it possible to find numerical solutions satisfying various accuracy requirements in a single run, which so far was considered unrealistic.

If the integration stepsize is sufficiently small, the error of this solution does not exceed the prescribed tolerance. Yu. There are many general forms an ODE can take, and these are classified in practice (see below). Weiner, G.Yu.

Unfortunately, even when implemented effectively, adaptive Nordsieck formulas cannot provide quasi-consistent integration (as defined above) because of the order reduction phenomenon, which appears on variable meshes (see[16]).

The capacity for deriving numerical solutions satisfying user-supplied accuracy conditions in automatic mode is confirmed by numerical experiments on two test problems.Do you want to read the rest of this article?Request

General linear methods are studied in detail in[4]. In addition, we supply our numerical schemes with an automatic global error control mechanism to arrive at the adaptive numerical technique for solving differential equations of preassigned quality. Math. Berezin and N.

In the present investigation, file information was reviewed to determine the presence of a variety of mental health conditions. In other words, quasi-consistent Nordsieck methods on fixed step size meshes have a higher order of convergence than on variable step size ones. http://xhpcreations.com/global-error/global-error-handler-vb6.html All these schemes exploit the property of double quasi-consistency, which implies that the numerical solutions produced by such methods have the asymptotically equal local and true errors.
