  A two sets of test problems are tested upon, the first set consists of problems on ordinary differential equations and the second set consists of problems on delay differential equations. The problems are solved using the new RKD method and numerical comparisons are made when the same problems are reduced to a first order system of ODEs and first order system of DDEs and solved using the existing Runge-Kutta methods of order three and four. The RKD method is adapted to solve delay differential equations (DDEs). Stability polynomial of the method for linear special third order DDEs is given. The numerical results have clearly shown the advantage and the efficiency of the new method in terms of accuracy and computational time.

  In this study, an optimized explicit Runge-Kutta (RK) method which is based on a method of Dormand with six-stage and fifth algebraic order with FSAL property denoted as the ORK5 method is constructed. The proposed method solves first-order Ordinary Differential Equations (ODEs) by first converting the second order ODEs to an equivalent first order. The new method has zero phase-lag, zero amplification error and zero first derivative of the phase-lag. Absolute stability of the new method is as well shown. The numerical experiments are carried out to show the efficiency of the derived method in comparison with other existing RK methods.
