Proximal Gauss–Newton method

open access: yes, 2018
Capítulo del libro "Contemporary study of iterative methods: convergence, dynamics and applications" In this chapter we extend the solvability of penalized nonlinear least squares problems using the proximal Gauss–Newton method. Moreover, a numerical example validating the theoretical results is also presented.

INVERSE-FREE NEWTON'S METHOD

open access: yesJournal of Applied Analysis & Computation
Summary: We present a modification of Newton's method for finding a zero of a multivariable function without an inverse of a matrix in a recurrence. The aim of this paper is twofold: demonstrating at least quadratic convergence of a Newton-type method avoiding matrix inversion under standard assumptions, and then comparing modified and classical Newton'

Some properties of the basins of attraction of the Newton’s method for simple nonlinear geodetic systems

open access: yesReports on Geodesy and Geoinformatics
The research presented in this paper concerns the determination of the attraction basins of Newton’s iterative method, which was used to solve the non-linear systems of observational equations associated with the geodetic measurements.

Approximations of continuous Newton's method: An extension of Cayley's problem

open access: yesElectronic Journal of Differential Equations, 2007
Continuous Newton's Method refers to a certain dynamical system whose associated flow generically tends to the roots of a given polynomial. An Euler approximation of this system, with step size $h=1$, yields the discrete Newton's method algorithm for ...

A Low-complexity Successive Detection Method for OFDM Systems over Doubly Selective Channels

open access: yesJournal of Communications Software and Systems, 2008
For OFDM systems, the time variation of a multipath channel results in inter-carrier interference (ICI). It leads to performance degradations. In reducing the problem, current successive detection methods cost very high computationalcomplexities.
