Abstract
This paper describes a new practical strategy to detect stiffness based on explicit Runge-Kutta schemes. This strategy implements an operative definition of stiffness based on the computation of two conditioning parameters. Test results, using a modified version of the MATLAB code DOPRI5, indicate that the new strategy is able to detect whether a problem could be solved more efficiently by an implicit method.
