Almost sure stability of the Euler-Maruyama method with random variable stepsize for stochastic differential equations [PDF]

open access: yes, 2016
In this paper, the Euler–Maruyama (EM) method with random variable stepsize is studied to reproduce the almost sure stability of the true solutions of stochastic differential equations.

New generalized variable stepsizes of the CQ algorithm for solving the split feasibility problem

open access: yesJournal of Inequalities and Applications, 2017
Variable stepsize methods are effective for various modified CQ algorithms to solve the split feasibility problem (SFP). The purpose of this paper is first to introduce two new simpler variable stepsizes of the CQ algorithm.

A Variable Stepsize Implementation for Stochastic Differential Equations [PDF]

open access: yesSIAM Journal on Scientific Computing, 2003
Summary: Stochastic differential equations (SDEs) arise from physical systems where the parameters describing the system can only be estimated or are subject to noise. Much work has been done recently on developing higher order Runge--Kutta methods for solving SDEs numerically.

An almost cyclic 2-coordinate descent method for singly linearly constrained problems [PDF]

open access: yes, 2019
A block decomposition method is proposed for minimizing a (possibly non-convex) continuously differentiable function subject to one linear equality constraint and simple bounds on the variables.

Construction of Variable-Stepsize Multistep Formulas [PDF]

open access: yesMathematics of Computation, 1986
A systematic way of extending a general fixed-stepsize multistep formula to a minimum storage variable-stepsize formula has been discovered that encompasses fixed-coefficient (interpolatory), variable-coefficient (variable step), and fixed leading coefficient as special cases.

An Online Parallel and Distributed Algorithm for Recursive Estimation of Sparse Signals [PDF]

open access: yes, 2015
In this paper, we consider a recursive estimation problem for linear regression where the signal to be estimated admits a sparse representation and measurement samples are only sequentially available.

A Variable Step-size CLMS Algorithm and Its Analysis [PDF]

open access: yesRadioengineering, 2020
In this paper, a hyperbolic tangent variable step-size convex combination of the least mean square (HTVSCLMS) algorithm is proposed and analyzed. This work avoids the compromise between the convergence speed and the steady-state error for two filters in ...

A Unified Successive Pseudo-Convex Approximation Framework [PDF]

open access: yes, 2016
In this paper, we propose a successive pseudo-convex approximation algorithm to efficiently compute stationary points for a large class of possibly nonconvex optimization problems.
