Runge-Kutta methods are the classic family of solvers for ordinary differential equations (ODEs), and the basis for the state of the art. Like most numerical meth-
The explicit methods are those where the matrix [] is lower triangular. Forward Euler. The Euler method is first order. The lack of stability and accuracy limits its popularity mainly to use as a simple introductory example of a numeric solution method.
When the stepsize in Runge-Kutta codes is restricted by stability, an uneven pattern of stepsizes with many step rejections is frequently observed. A modified strategy is proposed to smooth out this type of behaviour. Several new estimates for the dominant eigenvalue of the Jacobian are derived. It

result of an embedded formula of order -1. Most notably, in m the 1960’s, Fehlberg [7] developed a number of very efficient, embedded explicit Runge-Kutta methods using this approach.
