摘要
We present a new explicit Runge-Kutta method of fourth algebraic order with minimum error of the fifth algebraic order (whose limit is zero, when the step-length tends to zero) and infinite order of dispersion and dissipation. The numerical results of a wide range of methods when these are applied to well-known periodic orbital problems show the efficiency of the new constructed method. (C) 2004 Elsevier B.V.
