Giovanni Romeo, in Elements of Numerical Mathematical Economics with Excel, 2020. Runge-Kutta of fourth-order method. The Runge-Kutta method attempts to overcome the problem of the Euler's method, as far as the choice of a sufficiently small step size is concerned, to reach a reasonable accuracy in the problem resolution.. On the other hand, the minus of the Runge …

The Runge-Kutta integration formulas are a little more complicated than the simple formula we used with Euler's basic method. The general equations are as follows: y' represents dy/dx in these equations. You can see that every step requires four intermediate computations prior to predicting the next y-value, that is, y (x + dx).
