Abstract

In this paper we introduce an explicit one-step method that can be used for solving stiff problems. This method can be viewed as a modification of the explicit third order runge-kutta method using the contraharmonic mean (CoM) that allows rducing the stiffiness in some sense. The stability of the method is analyzed and numerical results shown to verify the conclusions.numerical examples indicate that this method is superior compared to some existing methods including the third and fourth order contraharmonic mean methods, ABM method, classical third order Runge-Kutta, and Wazwaz method.
