This presentation will briefly address some of the deficiencies of current functionals (especially self-interaction error) and our proposed remedies: (1) hybrid functionals whose portion of exact exchange depends on the position (i.e., local rather than global hybrids), and (2) hybrid functionals whose exact exchange component is based on a screened Coulomb potential.
