Journal of Inequalities and Applications, 2020 In this paper, we study the alternating CQ algorithm for solving the split equality problem in Hilbert spaces. It is, however, not easy to implement since its selection of the stepsize requires prior information on the norms of bounded linear operators ...

On the zero stability of the variable order variable stepsize BDF-Formulas
Numerische Mathematik, 1990 The authors derive bounds for the mesh-size ratios \(h_{j+1}/h_ j\) of nonequidistant grids such that variable order backward differentiation formulas are zero-stable. In the case of 3-step formulas the results of the third author and \textit{P. J. Paes-Lemme} [BIT 24, 85-91 (1984; Zbl 0554.65052)] are substantially improved.

CAAI Transactions on Intelligence Technology, EarlyView.ABSTRACT Repetitive motion planning (RMP) for redundant manipulators with high convergent precision becomes an intense research topic due to its more degrees of freedom. In this paper, a specific zeroing neural dynamics (SZND) model for the RMP is first set up via zeroing neurodynamics.

Solving third-order Lane–Emden–Fowler equations using a variable stepsize formulation of a pair of block methods. [PDF]
, 2023 [EN]This manuscript presents a variable stepsize formulation of a pair of block methods to efficiently solve third-order IVP models of Lane–Emden–Fowler type equations. The main method is obtained considering two intermediate points. This method combines

Repelled Point Processes With Application to Numerical Integration
Scandinavian Journal of Statistics, EarlyView.ABSTRACT We look at Monte Carlo numerical integration from a stochastic geometry point of view. While crude Monte Carlo estimators relate to linear statistics of a homogeneous Poisson point process (PPP), linear statistics of more regularly spread point processes can yield unbiased estimators with faster‐decaying variance, and thus lower integration ...

A Novel Individual Variable Step-Size Subband Adaptive Filter Algorithm Robust to Impulsive Noises
IEEE Access, 2021 This paper proposes a novel individual variable step-size subband adaptive filter algorithm robust to impulsive noises. A fixed step-size subband adaptive filter algorithm that is robust against impulsive noises is newly derived by obtaining the optimal ...

Optimizing 3D Bin Packing of Heterogeneous Objects Using Continuous Transformations in SE(3)
Advanced Intelligent Systems, Volume 8, Issue 6, June 2026.This article presents a method for solving the three‐dimensional bin packing problem for heterogeneous objects using continuous rigid‐body transformations in SE(3). A heuristic optimization framework combines signed‐distance functions, neural network approximations, point‐cloud bin modeling, and physics simulation to ensure feasibility and stability ...

A Variable Step-Size Unconstrained Adaptive FD-LMS Algorithm for MDM Transmission
IEEE Photonics Journal, 2018 Mode-division multiplexing (MDM) over few-mode fibers has been proposed to break through the Shannon limit of the single-mode fiber. Mode coupling and differential mode group delay are two major drawbacks, which limit the performance of the system.
