A chaos wolf optimization algorithm with self-adaptive variable step-size
AIP Advances, 2017 To explore the problem of parameter optimization for complex nonlinear function, a chaos wolf optimization algorithm (CWOA) with self-adaptive variable step-size was proposed.

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 ...

Continuation Methods for Higher‐Order Topology Optimization
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 3, September 2026.ABSTRACT We aim to solve a topology optimization problem where the distribution of material in the design domain is represented by a density function. To obtain candidates for local minima, we want to solve the first‐order optimality system via Newton's method.

Continuous variable stepsize explicit pseudo two-step RK methods [PDF]
, 1999 The aim of this paper is to apply a class of constant stepsize explicit pseudo two-step Runge-Kutta methods of arbitrarily high order to nonstiff problems for systems of first-order differential equations with variable stepsize strategy.

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.

Inferring Io's Internal Properties by Combining Gravity Measurements and Volcanic Activity
Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.Abstract With its extreme geological activity, Io represents an archetype for tidally heated exoplanets/moons and provides insight into early stages of terrestrial planet evolution. Decades of ground‐based observations and multiple space missions have refined our understanding of Io, yet it remains debated where inside Io the tidal heating takes place.

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 ...

Repelled Point Processes With Application to Numerical Integration
Scandinavian Journal of Statistics, Volume 53, Issue 3, Page 1101-1133, September 2026.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 ...

Variable stepsize variable order multistep methods for stiff ordinary differential equations
, 1985 Backward differentiation methods are used extensively for integration of stiff systems of ordinary differential equations. During the integration, the steplength and order are controlled so that the estimated local error is less than some user prescribed

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.
