Diagonally Implicit Runge–Kutta methods. Diagonally Implicit Runge–Kutta (DIRK) formulae have been widely used for the numerical solution of stiff initial value problems. The simplest method from this class is the order 2 implicit midpoint method. Kraaijevanger and Spijker's two-stage Diagonally Implicit Runge–Kutta method:

Jul 02, 2021 · It is based on the first-disretize-then-optimize approach and combines a discrete adjoint WENO scheme of third order with the classical strong stability preserving three-stage third-order Runge–Kutta method SSPRK3. We analyze its approximation properties and apply it to optimal control problems of tracking-type with non-smooth target states.

An s-stage Runge-Kutta method has roughly s^2 coefficients (roughly s^2/2 for explicit meth-ods), which can be chosen so as to provide high accuracy, stability, or other properties. His-torically, most interest in Runge-Kutta methods has focused on methods using the minimum number of stages for a given order of accuracy.

Strong-Stability preserving Runge-Kutta time-steppers. The Gkyl DG solvers use SSP-RK time-steppers. Three steppers are implemented: SSP-RK2, SSP-RK3 and a four-stage SSP-RK3 that allows twice the CFL (for the cost of additional memory) as the other schemes. See [DurranBook] page 56. The schemes are described below.
