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.

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.

Explicit two-step Runge-Kutta methods [PDF]

open access: yes, 1995
summary:The explicit two-step Runge-Kutta (TSRK) formulas for the numerical solution of ordinary differential equations are analyzed. The order conditions are derived and the construction of such methods based on some simplifying assumptions is described.

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.
