Many of us know the most common types of SCF
(though we can do better than Wikipedia at explaining them):
- RHF (Restricted Hartree-Fock), RKS (Restricted Kohn-Sham) [link to answer]
- UHF (Unrestricted Hartree-Fock), UKS (Unrestricted Kohn-Sham) [link to answer]
- ROHF (Restricted Open-Shell Hartree-Fock), ROKS (Restricted open-shell KS)
But there's also less commonly known (and more powerful!) single-reference SCF methods:
- GHF (Generalized Hartree-Fock), GKS (Generalized Kohn-Sham) [link to answer]
- PHF (Projected Hartree-Fock)
- DHF (Dirac-Hartree-Fock) or Dirac-Fock [link to answer]
- KR-DHF (Kramers Restricted DHF)
- KU-DHF (Kramers Unrestricted DHF)
- SOSCF (Second-order Hartree-Fock)
- TD-SCF (Time-dependent SCF)
- Complex GHF
- GHF (Generalized HF of Valatin in 1961).
- GVB (Generalized Valence Bond) [link to answer]
Let's be the resource where people can learn these methods succintly!
(3 or fewer paragraphs please).

- Note that RHF sometimes stands for Roothan-Hartree-Fock.
