Webtion. No advantage over explicit Runge-Kutta or multistep methods is then left [4, Chap. VIII]. The remaining possibility is to control step size using present information only. Several such attempts have been made. For reversible differential equations, so-called reversible step size strategies were proposed by Hut, Makino, and McMillan [8] and Web“ Explicit symplectic integrators have been important tools for accurate and efficient approximations of mechanical systems with separable Hamiltonians. ... The integrator is inspired by the non-symplectic and non-reversible integrator in Gonçalves Ferrari et al. (2014), SAKURA, and makes use of Kepler solvers. Like SAKURA we decompose the N ...
