Newton's algorithm for discrete classical dynamics

A recent article in J. Chem. Phys. argues that the two algorithms, the velocity-Verlet and position-Verlet integrators, commonly used in Molecular Dynamics (MD) simulations, are different [L. Ni and Z. Hu, J. Chem. Phys. 161, 226101 (2024)]. However, not only are the two algorithms just different formulations of the same discrete algorithm, but also are other simple discrete algorithms used in MD simulations in the natural sciences. They are all reformulations of the discrete algorithm derived by Newton in 1687 in Proposition I in the very first part of his book Principia. The different reformulations of Newton's algorithm for discrete dynamics lead to identical discrete dynamics with the same invariances, momentum, angular momentum, and energy as Newton's analytical dynamics. Hundreds of thousands of MD simulations with Newton's discrete dynamics have appeared but unfortunately with many recorded errors for energies, potential energies, temperatures, and heat capacities. The public software for MD should be corrected.
