High speed evaluation of F 0(x)

Title of program: DFZERO Catalogue Id: ACAA_v1_0 Nature of problem Much physical insight into the fundamental nature of molecules arises directly and indirectly from the calculation of the electronic energy. However, the ease of evaluating the various integrals that arise in the calculation of the electronic energy is strongly basis set dependent. The use of spherical Gaussian basis orbitals allows major simplifications to occur in the integral evaluations, for all of the integrals that are required can be evaluated analytically, and require only the auxiliary ...
