The computational implementation of orbital functionals has become one of the great modern challenges for density-functional theory (DFT). In static cases, the exact procedure of implementing orbital functionals is the so-called optimized effective potential method (OEP). In situations involving temporal variations, in the context of the time-dependent density-functional theory (TDDFT), TDOEP becomes the correct approach. However, both OEP and TDOEP are known by their severe computational costs…

Simple implementation of complex functionals: scaled self-consistency.
Three approximate schemes allowing simple implementation of complex density functionals by making use of self-consistent implementation of simpler functionals are explored and compared and scaled approaches turn out to be, on average, better than post approaches, and unlike these also provide corrections to eigenvalues and orbitals.
