What is Variable Step Symplectic Integration Methods about?

This article presents a meta-algorithm that enables the use of variable time steps in symplectic methods for Hamiltonian systems, preserving their favorable long-time integration properties. The algorithm is theoretically justified through backward error analysis and is illustrated with numerical experiments. It addresses the challenge of maintaining efficiency in variable step scenarios, particularly in cases like Kepler
