All elementary functions from a single binary operator
Single binary op eml(x,y)=exp(x)−ln(y) + constant 1 can express all elementary functions; authors recover sin, cos, sqrt, log from data with shallow EML trees.

- v2 with figures + completeness sketch on arXiv linked in thread
- Not regression‑competitive; expression blow‑up, but DAG sharing helps
