Webb5 mars 1999 · The results for the re-parameterization of the Perdew-Burke-Ernzerhof generalized gradient approximation exchange-correlation energy functional and related PBE hybrid indicate that improvement at the GGA level of complexity does not necessarily provide the best GGA for use in a hybrid. A hybrid exchange–correlation functional is usually constructed as a linear combination of the Hartree–Fock exact exchange functional and any number of exchange and correlation explicit density functionals. The parameters determining the weight of each individual functional are typically specified by fitting the functional's predictions to experimental or accurately calculated thermochemical data, although … east cheshire safeguarding adults
