High Order Optimized Geometricintegrators for Linear
نویسندگان
چکیده
In this paper new integration algorithms for linear diierential equations up to eighth order are obtained. Starting from Magnus expansion, methods based on Cayley transformation and Fer expansion are also built. The structure of the exact solution is retained while the computational cost is reduced compared to similar methods. Their relative performance is tested on some illustrative examples.

A New High-order Takagi-Sugeno Fuzzy Model Based on Deformed Linear Models
Amongst possible choices for identifying complicated processes for prediction, simulation, and approximation applications, high-order Takagi-Sugeno (TS) fuzzy models are fitting tools. Although they can construct models with rather high complexity, they are not as interpretable as first-order TS fuzzy models. In this paper, we first propose to use Deformed Linear Models (DLMs) in consequence pa...
متن کاملAN EXPERIMENTAL INVESTIGATION OF THE SOUNDS OF SILENCE METAHEURISTIC FOR THE MULTI-MODE RESOURCE-CONSTRAINED PROJECT SCHEDULING WITH PRE-OPTIMIZED REPERTOIRE ON THE HARDEST MMLIB+ SET
This paper presents an experimental investigation of the Sounds of Silence (SoS) harmony search metaheuristic for the multi-mode resource-constrained project scheduling problem (MRCPSP) using a pre-optimized starting repertoire. The presented algorithm is based on the time oriented version of the SoS harmony search metaheuristic developed by Csébfalvi et al. [1] for the single-mode resource-con...
متن کاملEffects of optimized photorefractive keratectomy (PRK) operation on the asphericity and high-order aberration changes
Background: Optimized is a common and important method in which aberrations are created by the device and the surgeon, but high-grade aberrations are out of the surgeon's control and are induced by the device in the patient. The aim of this study was the evaluation of out-of-control high-order aberration changes before and after PRK surgery and these impact on vision outcome. Materials and meth...
متن کاملHigh Order Implicit-Explicit General Linear Methods with Optimized Stability Regions
In the numerical solution of partial differential equations using a method-of-lines approach, the availability of high order spatial discretization schemes motivates the development of sophisticated high order time integration methods. For multiphysics problems with both stiff and non-stiff terms implicit-explicit (IMEX) time stepping methods attempt to combine the lower cost advantage of expli...
متن کاملSchwarz preconditioning for high order edge element discretizations of the time-harmonic Maxwell's equations
We focus on high order edge element approximations of waveguide problems. For the associated linear systems, we analyze the impact of two Schwarz preconditioners, the Optimized Additive Schwarz (OAS) and the Optimized Restricted Additive Schwarz (ORAS), on the convergence of the iterative solver.
