Accelerated Runge-Kutta Methods [PDF]

open access: yesDiscrete Dynamics in Nature and Society, 2008
Standard Runge-Kutta methods are explicit, one-step, and generally constant step-size numerical integrators for the solution of initial value problems. Such integration schemes of orders 3, 4, and 5 require 3, 4, and 6 function evaluations per time step ...

Semantic Segmentation of Medical Images Based on Runge–Kutta Methods [PDF]

open access: yesBioengineering, 2023
In recent years, deep learning has achieved good results in the semantic segmentation of medical images. A typical architecture for segmentation networks is an encoder–decoder structure.

Spatially partitioned embedded Runge-Kutta Methods [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2013
We study spatially partitioned embedded Runge–Kutta (SPERK) schemes for partial differential equations (PDEs), in which each of the component schemes is applied over a different part of the spatial domain.

Diagonally Implicit Symplectic Runge-Kutta Methods with High Algebraic and Dispersion Order [PDF]

open access: yesThe Scientific World Journal, 2014
The numerical integration of Hamiltonian systems with oscillating solutions is considered in this paper. A diagonally implicit symplectic nine-stages Runge-Kutta method with algebraic order 6 and dispersion order 8 is presented.

Solving system of Euler's equations using Runge –Kutta methods [PDF]

open access: yesمجلة جامعة الانبار للعلوم الصرفة, 2023
In this paper, linear systems with variable coefficients (Euler's equations) were solved using one of the numerical methods that are subject to initial conditions defined over a given period of time .The explicit Rung-Kutta method is the fastest and most

Runge–Kutta–Möbius methods

open access: yesPeriodica Mathematica Hungarica, 2023
AbstractIn the numerical integration of nonlinear autonomous initial value problems, the computational process depends on the step size scaled vector field hf as a distinct entity. This paper considers a parameterized transformation $$\begin{aligned} hf \mapsto hf \circ (I-\gamma hf)^{-1}, \end{aligned}$$

Krylov SSP Integrating Factor Runge–Kutta WENO Methods

open access: yesMathematics, 2021
Weighted essentially non-oscillatory (WENO) methods are especially efficient for numerically solving nonlinear hyperbolic equations. In order to achieve strong stability and large time-steps, strong stability preserving (SSP) integrating factor (IF ...

Continuous stage stochastic Runge–Kutta methods

open access: yesAdvances in Difference Equations, 2021
In this work, a version of continuous stage stochastic Runge–Kutta (CSSRK) methods is developed for stochastic differential equations (SDEs). First, a general order theory of these methods is established by the theory of stochastic B-series and ...
