The primary Euler paper explicitly describes the PINN method as a practical, well-conditioned numerical discovery tool for the Euler blowup profile, supporting the claim's practical-methodology component, though not independently proving the comparative “more practical than Navier–Stokes” judgment.

The PINN serves as a numerical discovery tool that allows us to locate an approximate self-similar profile with high accuracy in a practical and well-conditioned way, especially when direct optimization over analytic ansatz would be difficult or unstable.
