A C++ implementation of the G-Scheme stiff ODE solver with multi-resolution sparse hash-table kernel lookup
Riccardo Malpica Galassi, Mauro Valorani
The paper presents a C++ implementation of the G‑Scheme stiff ODE solver that uses a precomputed multi‑resolution sparse hash‑table to retrieve kernel sets instead of computing the…

The Algebra of Units: From Buckingham's Pi-grec Theorem to Latent-Variable Learning
Mauro Valorani
Engineers often measure many quantities-speed, pressure, temperature, length-expressed in different physical units. The Buckingham Pi-grec theorem states that these variables can a…
