Abstract:
The simplest equations are considered that simulate the behavior of various error components of Runge–Kutta methods. The expressions for the local and global errors are obtained. The minimization of these errors allows one to construct explicit and implicit methods that have an improved accuracy when solving stiff and differential-algebraic problems.
Keywords:
Runge–Kutta methods, still problems, differential-algebraic problems, order reduction phenomen.
