RESEARCH OF ONE VARIANT OF SUBGRADIENT METHOD
Вестник Кемеровского государственного университета, 2015 The subgradient step selection method based on the known minimal value of function is studied in the paper. The authors show that it is an analogue of the method of minimal errors for solving linear equation systems.

Newtonian Property of Subgradient Method with Optimization of Metric Matrix Parameter Correction
MathematicsThe work proves that under conditions of instability of the second derivatives of the function in the minimization region, the estimate of the convergence rate of Newton’s method is determined by the parameters of the irreducible part of the ...

Can tropical cyclones exist near the Equator?
Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 774, January 2026 Part A.Schematic showing how a developed TC responds to reduced Coriolis parameter (f). Zero‐f lowers inertial stability and increases agradient force, enhancing radial inflow at lower levels. Stronger inflow deepens the inflow layer and promotes convergence, intensifying convection and downdrafts in outer rainbands.

Incremental and Parallel Machine Learning Algorithms With Automated Learning Rate Adjustments
Frontiers in Robotics and AI, 2019 The existing machine learning algorithms for minimizing the convex function over a closed convex set suffer from slow convergence because their learning rates must be determined before running them.

A Hierarchical Cooperation Power Management Strategy for ADN‐MG Systems
IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.Distributed generators (DGs) are mostly connected to the active distribution networks (ADNs) through microgrids (MGs) or microgrid clusters (MGCs) to support the power balance of the ADNs. Real‐time power dispatching between ADNs and the MGs is a major research hotspot and difficulty in current ADN‐MG cooperation systems.

An augmented subgradient method for minimizing nonsmooth DC functions
, 2021 A method, called an augmented subgradient method, is developed to solve unconstrained nonsmooth difference of convex (DC) optimization problems. At each iteration of this method search directions are found by using several subgradients of the first DC ...

An Extension of Subgradient Method for Variational Inequality Problems in Hilbert Space
Abstract and Applied Analysis, 2013 An extension of subgradient method for solving variational inequality problems is presented. A new iterative process, which relates to the fixed point of a nonexpansive mapping and the current iterative point, is generated.

Optimal Sparse Array Design Against Desired Signal DOA Mismatch for Robust Adaptive Beamforming
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.The performance of the adaptive beamformer is not only related to the array weight but also influenced by the array structure. Different sparse array configurations exhibit varying sensitivities to uncertainties in the signal direction of arrival (DOA).
