Classical Runge-Kutta of order 4. So far the most often used is the classical fourth-order Runge-Kutta formula, which has a certain sleekness of organization about it: k 1 = f n = f ( x n, y n), k 2 = f ( x n + h 2, y n + h 2 k 1), k 3 = f ( x n + h 2, y n + h 2 k 2), k 4 = f ( x n + h, y n + h k 3). The fourth-order Runge-Kutta method requires ...

Adaptive methods are designed to produce an estimate of the local truncation error of a single Runge–Kutta step. This is done by having two methods, one with order and one with order . These methods are interwoven, i.e., they have common intermediate steps. Thanks to this, estimating the error has little or negligible computational cost compared to a step with the higher-order method.

This program implements Runge Kutta (RK) fourth order method for solving ordinary differential equation in Python programming language. Output of this Python program is solution for dy/dx = x + y with initial condition y = 1 for x = 0 i.e. y (0) = 1 and we are trying to evaluate this differential equation at y = 1 using RK4 method ( Here y = 1 ...
