WebIn numerical analysis, the Runge–Kutta methods (English: / ˈ r ʊ ŋ ə ˈ k ʊ t ɑː / RUUNG-ə-KUUT-tah) are a family of implicit and explicit iterative methods, which include the Euler method, used in temporal discretization for the approximate solutions of simultaneous nonlinear equations. WebAbstract. This paper we are dealing with the high order accurate low storage explicit Runge Kutta (LSERK) methods which mainly are used for temporal discretization and are stable regardless of its accuracy. The main objective of this paper is to compare traditional RK with different forms of LSERK methods. The numerical experiments indicate ...

WebExplicit vs. implicit methods: Numerical methods can be classi ed as explicit and implicit. Implicit methods often have better stability properties, but require an extra step of solving non-linear equations using e.g., Newton’s method. Adaptive methods: Similarly to integration, it is more e cient to vary the step size.
