Chebyshev Polynomial Iterations and Approximate Solutions of Linear Operator Equations
An iteration scheme for the approximate solution of a linear operator equation in a Banach space is discussed from the viewpoint of Chebyshev polynomials. The optimal rate of convergence is described by numerical characteristics which are similar to (but different from) the classical Chebyshev constants.

Dynamic multi‐objective optimisation of complex networks based on evolutionary computation
Abstract As the problems concerning the number of information to be optimised is increasing, the optimisation level is getting higher, the target information is more diversified, and the algorithms are becoming more complex; the traditional algorithms such as particle swarm and differential evolution are far from being able to deal with this situation ...

ON COMPARISONS OF CHEBYSHEV-HALLEY ITERATION FUNCTIONS BASED ON THEIR ASYMPTOTIC CONSTANTS [PDF]
Using the Chebyshev-Halley family of iteration functions and numerical examples, we discuss the influence of both the asymptotic constant and the choice of the initial trial in the basin of attraction on the rapidity of convergence of an iterative method.

ON THE STABILITY OF THE CHEBYSHEV ITERATIVE METHOD
Numerical solution of the systems of linear equations (linear system), especially in case of nonstationary problems, takes a significant part of computer time. Normally, for solving linear system the applied program packages use either Chebyshev iterative method (wave linear problems etc.), which requires setting the optimal parameter, or gradient ...

Low-rank Linear Fluid-structure Interaction Discretizations [PDF]
Fluid-structure interaction models involve parameters that describe the solid and the fluid behavior. In simulations, there often is a need to vary these parameters to examine the behavior of a fluid-structure interaction model for different solids and ...

A new eighth-order Chebyshev-Halley type iteration is proposed for solving nonlinear equations and matrix sign function. Basins of attraction show that several special cases of the new method are globally convergent.
