A non-standard explicit integration scheme for initial-value problems

In this paper we present the construction of a non-standard explicit algorithm for initial-value problems. The method results to be of second order and A-stable. This new algorithm has been proven to be suitable for solving different kind of initial-value problems, specifically, non-singular problems, singular problems, stiff problems and singularly perturbed problems. Some numerical experiments are considered in order to check the behaviour of the method when applied to a variety of initial-value problems.
