AutoSINDy automatically builds a tailored basis library from PySR symbolic regression and applies SINDy to recover ground-truth nonlinear dynamics with 92.8% success under noise.
Nested trigonometric compositions (e.g.sin(sin(·))) are explicitly forbidden via nested constraints, preventing the evolutionary search from exploiting degenerate identities
