“…On the other hand, Euler is the computationally fastest, whereas RK4 is the slowest. The experiments in [7,22] indicate, for the one example, that RK2 is a good compromise between precision and efficiency. The "step size" (or "time increment") between each visited point in time is the parameter of these approximation methods; the smaller the step size, the more accurate the numerical approximation, and the longer the computation time.…”
