Numerical solutions of fuzzy differential equations by extended Runge-Kutta-like formulae of order 4. (English) Zbl 1238.65068
Summary: We apply a numerical algorithm for solving the fuzzy first order initial value problem, based on extended Runge-Kutta-like formulae of order 4. We use Seikkala’s derivative. The elementary properties of this new solution are given. We use the extended Runge-Kutta-like formulae in order to enhance the order of accuracy of the solutions using evaluations of both $$f$$ and $$f^{\prime}$$, instead of the evaluations of $$f$$ only.
