Among the most popular methods for the solution of the Initial Value Problem are the Runge–Kutta (RK) pairs. These methods can be derived by solving a system of nonlinear equations after admitting various simplifying assumptions. The more simplifying assumptions we consider the more we narrow the solution space. In  Tsitouras presented an algorithm for the construction of Runge–Kutta pairs of orders 5 and 4 satisfying only the so called “first column simplifying assumption”. In  Famelis and Tsitouras have studied the ability of Differential Evolution techniques to find solutions satisfying all the order conditions needed for the derivation of orders 5 and 4 pairs. In this work we propose an modification on the Differential Evolution strategy for the same problem. The current study will be a guide to the construction of other classes of RK that have not been presented in the literature.
