Simulation of stochastic auto-oscillating systems through variable stepsize algorithms with small noise [PDF]
, 1994 The paper considers some questions of the numerical analysis of stochastic auto-oscillating systems and their simulation on computers. A low computer costs, variable stepsize algorithm based on local error estimation of stochastic Runge-Kutta- Fehlberg ...

An Alternating Variable Step-Size Adaptive Long-Range Prediction of LMS Fading Signals
International Journal of Distributed Sensor Networks, 2015 We propose a linear alternating variable step-size adaptive long-range prediction (AVSS-ALRP) scheme to predict fading signals which is especially suitable for a versatile two-state land mobile satellite (LMS) channel model at S-band. A three-step design

A Variable Step-Size Exponentially Fitted Explicit Hybrid Method for Solving Oscillatory Problems
International Journal of Mathematics and Mathematical Sciences, 2011 An exponentially fitted explicit hybrid method for solving oscillatory problems is obtained. This method has four stages. The first three stages of the method integrate exactly differential systems whose solutions can be expressed as linear combinations ...

Variable stepsize implementation of implicit-explicit general linear methods [PDF]
, 2019 For effcient integration of such kind of systems we consider implicit-explicit (IMEX) methods, where the non-stiff part f(y) is integrated by an explicit numerical scheme, and the stiff part g(y) is integrated by an implicit numerical scheme. After the

A Variable Step-Size Regularization-Based Quasi-Newton Adaptive Filter for System Identification
IEEE AccessThe family of least mean square (LMS) based adaptive filtering algorithms suffers from convergence performance limitation due to the sensitivity of such algorithms to the eigenvalue spread of the input correlation matrix.

Stability properties of variable stepsize variable formula methods
Numerische Mathematik, 1978 When variable stepsize variable formula methods (VSVFM's) are used in the solution of systems of first order differential equations instability arises sometimes. Therefore it is important to find VSVFM's whose zerostability properties are not affected by the choice of both the stepsize and the formula. The Adams VSVFM's are such methods. In this work a
