Description
https://ui.adsabs.harvard.edu/abs/2015MNRAS.446.1424R/abstract
It's an adaptive symplectic integrator with superior speed and performance.
Currently the symplectic solver in diffrax is not adaptive. Implementing this solver would offer an improved symplectic option.

Research direction
Start by locating diffrax's existing symplectic solver and read the linked 2015 paper to understand the IAS15 algorithm and its adaptive-step requirements. Done means adding an adaptive symplectic solver as an improved option in diffrax, with its behavior and performance checked against the stated goals.
