{c}

The <Hartree-Fock method> approximates the <ground state> <wavefunction> by a single <Slater determinant>, minimizing the <expectation value> of the <Hamiltonian> over its occupied <orbitals>. It retains <fermionic exchange symmetry> exactly within that determinant but omits <electron correlation> beyond a single <Slater determinant>.
