Abstract

We describe the construction of explicit two-step Runge-Kutta methods of order p and stage order q = p-1 or q = p with large regions of absolute stability. This process is illustrated for the methods of order p = 2, and 3 and leads to new methods which are competitive with explicit Runge-Kutta methods of the same order.
