Semi-empirical methods derived from Hartree-Fock theory aim to reduce computational effort by approximating or eliminating electron repulsion integrals. Strategies include introducing adjustable parameters to replace ERI calculations and utilizing zero differential overlap methods like CNDO, INDO, N
