Standard Runge-Kutta methods are explicit, one-step, and generally constant step-size numerical integrators for the solution of initial value problems. The superiority of a symmertic method with non-vanishing interval of periodicity over a comparable Störmer-Cowell The symmetry conditions under which a linear multistep method possesses a non-vanishing interval of periodicityĪre established. In this paper it is shown that certain linear multistep methods of arbitrary stepnumber possessĪ periodicity property when the product of the steplength and the angular frequency lies within a certain interval, the interval Various modified Störmer-Cowell methods have been proposed to overcome this deficiency,īut they all require a priori knowledge of the frequency. Inwards for all values of the steplength.

Ordinary differential system suffers a deficiency, sometimes known as orbital instability, when the stepnumber exceeds two.įor a test problem describing uniform motion in a circular orbit, the numerical solution afforded by such a method spirals

It is well known that the popular Störmer-Cowell class of linear multistep methods for the initial value problem for a second-order Therefore, the new cubic root mean fourth order Runge-kutta formula was tested for efficiency, convergence and stability The results show that the formula has minimal errors, is consistent, converges, stable and it compares favourably well with other RKMs with relatively smaller time. A rigorous derivation was carried out through the process of binomial and Taylor series expansion to obtain the values of the parameters. Abstract A special type of fourth order Runge-Kutta Formula (RKF)for the solution of Initial Value Problems (IVPs) in Ordinary Differential Equation, whose step functions are made to obey the usual characteristics of Runge-Kutta Method (RKM) is established.
