GAMESS
From open-encyclopedia.com - the free encyclopedia.
GAMESS is a computational chemistry software program. GAMESS stands for "General Atomic and Molecular Electronic Structure System" and has since split into GAMESS-US and GAMESS-UK variants. Both packages can perform a number of general computational chemistry calculations, including Hartree-Fock, Density functional theory (DFT), configuration interaction (CI), and other advanced electronic structure methods.
