We also compare the implementation cost of these schemes with the simplified-Newton iteration and we present some numerical experiments on some well-known stiff test problems to show that the proposed iterations are reliable and efficient. high-order implicit runge-kutta methods Pérez-Rodríguez, S. sperezr@ull.es Montijano, Juan I. monti@unizar.es Vol. 41, num. 7-8 (Abril 2001), pp. 1009-1024 Comput.
