A Nonmonotone Inexact Newton Method [PDF]
Optimization Methods and Software, 2005 In this paper, we describe a variant of the inexact Newton method for solving nonlinear systems of equations.We define a nonmonotone inexact Newton step and a nonmonotone backtracking strategy.

Nonmonotone Derivative-Free Methods for Nonlinear Equations
Computational Optimization and Applications, 2007 In this paper we study nonmonotone globalization techniques, in connection with iterative derivative-free methods for solving a system of nonlinear equations in several variables.

Nonmonotone Spectral Projected Gradient Methods on Convex Sets
SIAM Journal on Optimization, 2000 Nonmonotone projected gradient techniques are considered for the minimizationof differentiable functions on closed convex sets. The classical projected gradient schemes are extended to include a nonmonotone steplength strategy that is based onthe Grippo ...

Inverse-Intensity-Weighted Generalized Estimating Equations With Irregularly Measured Longitudinal Data and Informative Dropout. [PDF]
Stat MedABSTRACT Longitudinal data are commonly encountered in biomedical research, including randomized trials and retrospective cohort studies. Subjects are typically followed over a period of time and may be scheduled for follow‐up at predetermined time points.

A modified filter nonmonotone adaptive retrospective trust region method. [PDF]
PLoS One, 2021 In this paper, aiming at the unconstrained optimization problem, a new nonmonotone adaptive retrospective trust region line search method is presented, which takes advantages of multidimensional filter technique to increase the acceptance probability of ...

AVIDbase: A biologically accurate structural dataset of nanobody-antigen complexes. [PDF]
Protein SciAbstract Accurate structural data in a standardized format is one of the key factors behind the success of machine learning (ML)‐based methods for protein design and structure prediction. However, their application to nanobody‐antigen complexes has lower success rates compared to globular protein complexes, partly due to the limited amount of high ...

An improved nonmonotone adaptive trust region method [PDF]
, 2019 In this paper, we incorporate a nonmonotone technique with the new proposed adaptive trust region radius (Shi and Guo, 2008) [4] in order to propose a new nonmonotone trust region method with an adaptive radius for unconstrained optimization.

Competition and Collaboration in the AI Race: Country-LevelDirectional Evidence for Risk Monitoring and Policy. [PDF]
Risk AnalABSTRACT Artificial intelligence (AI) is reshaping national economies, yet country‐level AI–macro relationships remain poorly understood. Using annual data for the United States and China, 1980–2020, we develop a four‐layer triangulation framework—Pattern Causality, Granger causality, VECM‐based cointegration, and lead–lag correlation—to map ...

First order theories for nonmonotone inductive definitions: recursively inaccessible and Mahlo [PDF]
, 2001 In this paper first order theories for nonmonotone inductive definitions are introduced, and a proof-theoretic analysis for such theories based on combined operator forms à la Richter with recursively inaccessible and Mahlo closure ordinals is ...

Abstract and Applied Analysis, 2012 We study the solvability of Dirichlet and Neumann problems for different classes of nonlinear elliptic systems depending on parameters and with nonmonotone operators, using existence theorems related to a general system of variational equations in a ...
