Both Runge-Kutta and linear multistep methods are available to solve initial value problems for ordinary differential equations in the R packages deSolve and all of these solvers use adaptive step size control, some also control the order of the formula adaptively, or switch between different types of methods, depending on the local properties of the equations to be   In Mathwe focused on solving nonlinear equations involving only a single vari-able.

We used methods such as Newton’s method, the Secant method, and the Bisection method. We also examined numerical methods such as the Runge-Kutta methods, that are used to solve initial-value problems for ordinary di erential equations.

However these Embedded pairs of explicit Runge-Kutta formulae have been widely used for the numerical integration of non-stiff systems of first order ordinary differential equations. Because explicit Runge-Kutta formulae do not in general have a natural underlying interpolant, most implementations of these formulae restrict the steplength of integration so   We examine various integration schemes for the time-dependent Kohn–Sham equations.

Contrary to the time-dependent Schrödinger’s equation, this set of equations is nonlinear, due to the dependence of the Hamiltonian on the electronic density. We discuss some of their exact properties, and in particular their symplectic structure.

Four different families of propagators are considered This excellent reference book is the first to attempt to survey the full range of methods for the parallel solution of ordinary differential equations (ODEs).

This is a relatively long subroutine compared to the one shown in Example implementing Euler's method, so I commented this one to help you navigate through it.

It turns out that most numerical methods for ordinary differential equations are able to exactly reproduce a linear solution. That is, if the solution of the differential equation is \(u=at+b \), the numerical method will produce the same solution: \(u_k=ak\Delta t + b \).
