Decentralized Inexact Cubic Newton Method With Consensus Procedure

IEEE Access
Distributed optimization is widely used in large-scale and privacy-preserving machine learning, where each agent stores a local objective and communicates only with its neighbors in a connected network.

Correcting Inconsistency in Linear Inequalities by Minimal Change in the Right Hand Side Vector [PDF]

Computer Science Journal of Moldova, 2009
Correcting an inconsistent set of linear inequalities by minimal changes in problem data is a well studied problem and up to now several algorithms have been developed to do this task. In this paper, we consider doing the minimal correction using the l 2

Generalized logarithmic error and Newton’s method for the 𝑚th root. [PDF]

Mathematics of Computation, 1970
The problem of obtaining optimal starting values for the calculation of integer roots using Newton’s method is considered. It has been shown elsewhere that if relative error is used as the measure of goodness of fit. then optimal results are not obtained when the initial approximation is a best fit.

Erwin Schrödinger und die Versuchungen der (Wissenschafts‐)Biografik: Vorurteilsgefüge und Mechanismen der Skandalisierung

Berichte zur Wissenschaftsgeschichte, EarlyView.
Since late 2021, serious allegations have been made against physicist Erwin Schrödinger, ranging from pedophilia to serial sexual abuse. These accusations have significantly tarnished the Nobel Prize winner's public reputation. The ongoing debate has repeatedly raised the question of whether, and to what extent, these grave allegations are justified ...

The influence of rivers on seabird foraging ecology

Biological Reviews, EarlyView.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Optimization of 3D‐Printed Structured Packings—Current State and Future Developments

Chemie Ingenieur Technik, EarlyView.
This paper gives an overview about structured packing development for distillation, surveying heuristic development cycles, computational fluid dynamics simulations, and additive manufacturing techniques. The emerging application of shape optimization to improve packings is emphasized, and its benefits, impact, and limitations are discussed.

A New Algorithm to Approximate Bivariate Matrix Function via Newton-Thiele Type Formula

Journal of Applied Mathematics, 2013
A new method for computing the approximation of bivariate matrix function is introduced. It uses the construction of bivariate Newton-Thiele type matrix rational interpolants on a rectangular grid. The rational interpolant is of the form motivated by Tan

Method for the Ecological and Economic Assessment of Mechanical Vapour Recompression in the WindaB Tool

Chemie Ingenieur Technik, EarlyView.
Method to assess economic and ecologic advantages of mechanical vapour recompression at early stage of development. Main correlations between design parameters and profitability as well as CO2 emission reductions are described shown in a case study of methanol–water.

Generalized Newton\u27s Method Based on Graphical Derivatives

, 2010
This paper concerns developing a numerical method of the Newton type to solve systems of nonlinear equations described by nonsmooth continuous functions. We propose and justify a new generalized Newton algorithm based on graphical derivatives, which have

Some quadrature-based versions of the generalized Newton method for solving nonsmooth equations

, 2011
In this paper, modifications of a generalized Newton method based on some rules of quadrature are studied. The methods considered are Newton-like iterative schemes for numerical solving systems of nonsmooth equations.
