Optimization-based search for nordsieck methods of high order with quadratic stability polynomials
We describe the search for explicit general linear methods in Nordsieck form for which the stability function has only two nonzero roots. This search is based on state-of-the-art optimization software.

The Z5 transformation for solving quasi-linear partial differential equations
The Z1-Z4 transformations proposed in our previous papers have acquired remarkable success in the field of linear partial differential equations, general solutions of a large number of typical equations were obtained for the first time, and exact ...

Numerical Methods for Ill-Posed, Linear Problems [PDF]
A means of assessing the effectiveness of methods used in the numerical solution of various linear ill-posed problems is outlined. Two methods: Tikhonov' s method of regularization and the quasireversibility method of Lattès and Lions are appraised from ...

A practical approach for the derivation of algebraically stable two-step Runge-Kutta methods
We describe an algorithm, based on a new strategy recently proposed by Hewitt and Hill in the context of general linear methods, for the construction of algebraically stable two-step Runge-Kutta methods.

Strong Stability Preserving Multistage Integration Methods
In this paper we systematically investigate explicit strong stability preserving (SSP) multistage integration methods, a subclass of general linear methods (GLMs), of order p and stage order q ≤ p.

Construction of Nordsieck Second Derivative General Linear Methods with Inherent Quadratic Stability
This paper describes the construction of second derivative general linear methods in Nordsieck form with stability properties determined by quadratic stability functions. This is achieved by imposing the so–called inherent quadratic stability conditions.

Some efficient Nordsieck integration methods for IVPs [PDF]
In this paper, in continuation of the construction of efficient numerical methods for stiff IVPs, we construct type two Nordsieck second derivative general linear methods with order p = s, where s is the number of internal stages, and stage order q = p ...

Linear stationary iterative methods for the force-based quasicontinuum approximation [PDF]
Force-based multiphysics coupling methods have become popular since they provide a simple and efficient coupling mechanism, avoiding the difficulties in formulating and implementing a consistent coupling energy.

Global error estimation for explicit second derivative general linear methods [PDF]
In this paper, we describe an approach to estimate the global error for explicit second derivative general linear methods based on the approach which has been already used for global error estimation of explicit general linear methods.

Genotype Selection for Grain Yield of Sorghum through Generalized Linear Mixed Model
The classical model only provides a correct analysis if all the effects are fixed. For experiments that include fixed and random effects, the general linear mixed model is appropriate for handling the non-normal distributed response variables. The aim of
