What method does FAC and GRASP used to generate electronic structure of ions? Do they work the same and how does FAC compute much faster than GRASP?

General Relativistic Atomic Structure Package (GRASP) uses the Multi-configuration Dirac-Hartree-Fock theory to compute the atomic energy levels of ions. What method does the FAC uses and if it...
