“…Moreover, Schlegel introduced a generic recursive multirate Runge-Kutta scheme of third order accuracy. In [18], the author developed an optimization of the explicit two-derivative sixth-order Runge-Kutta method in order to obtain low dissipation and dispersion errors. The method depends on two free parameters, used for the optimisation and the spatial derivatives are discretized by finite differences and Petrov-Galerkin approximations.…”

“…In Appadu et al 24 and Liska and Wendroff, 25 composite schemes which blends a dispersive scheme with a dissipative scheme to capture shock efficiently, is proposed. Low dissipation and low dispersion Runge Kutta schemes [26][27][28] have been widely used to achieve a reduction in dissipation and dispersion errors. This is mainly done by optimizing the temporal integration scheme.…”
