Explicit two-step Runge-Kutta methods
This paper analyses the class of explicit two-step Runge-Kutta methods. It is shown that for methods of order 5 or less, these methods require the same number of function evaluations as a Runge-Kutta method of one order less. In particular, a 4-stage order 5 method is constructed and some numerical tests are performed.
