Functional continuous Runge–Kutta–Nyström methods

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
Numerical methods for solving retarded functional differential equations of the second order with right-hand side independent of the function derivative are considered. The approach used by E. Nyström for second-order ordinary differential equations with

New class of hybrid explicit methods for numerical solution of optimal control problems [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2021
Forward-backward sweep method (FBSM) is an indirect numerical method used for solving optimal control problems, in which the differential equation arising from this method is solved by the Pontryagin’s maximum principle.

Spatially partitioned embedded Runge-Kutta Methods [PDF]

open access: yes, 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.

Computational Techniques Based on Runge-Kutta Method of Various Order and Type for Solving Differential Equations [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2019
The Runge-Kutta method is a one step method with multiple stages, the number of stages determine order of method. The method can be applied to work out on differential equation of the type’s explicit, implicit, partial and delay differential equation etc.

Optimal monotonicity-preserving perturbations of a given Runge-Kutta method [PDF]

open access: yes, 2018
Perturbed Runge--Kutta methods (also referred to as downwind Runge--Kutta methods) can guarantee monotonicity preservation under larger step sizes relative to their traditional Runge--Kutta counterparts.

Global error estimation of linear multistep methods through the Runge-Kutta methods [PDF]

open access: yesIranian Journal of Numerical Analysis and Optimization, 2016
In this paper, we study the global truncation error of the linear multistep methods (LMM) in terms of local truncation error of the corresponding Runge-Kutta schemes. The key idea is the representation of LMM with a corresponding Runge-Kutta method.
