The inexact, inexact perturbed, and quasi-Newton methods are equivalent models

E Cǎtinaş - Mathematics of Computation, 2005 - ams.org
A classical model of Newton iterations which takes into account some error terms is given by
the quasi-Newton method, which assumes perturbed Jacobians at each step. Its high …

How Many Steps Still Left to *?

E Catinas - SIAM review, 2021 - SIAM
The high speed of x_k→x^∗∈\mathbbR is usually measured using the C-, Q-, or R-orders:
\lim|x^∗-x_k+1||x^∗-x_k|^p_0∈(0,+∞),\qquad\lim\ln|x^∗-x_k+1|\ln|x^∗-x_k|=q_0,\qquador …

A survey on the high convergence orders and computational convergence orders of sequences

E Cătinaş - Applied Mathematics and Computation, 2019 - Elsevier
Twenty years after the classical book of Ortega and Rheinboldt was published, five
definitions for the Q-convergence orders of sequences were independently and rigorously …

[HTML][HTML] Estimating the radius of an attraction ball

E Cătinaş - Applied Mathematics Letters, 2009 - Elsevier
Given a nonlinear mapping G differentiable at a fixed point x∗, the Ostrowski theorem offers
the sharp sufficient condition for x∗ to be an attraction point, where ρ denotes the spectral …
