``deteriorate'' these states by optimizing the orbitals for the

\manurev{This can be rationalized as follows. As readily seen from
Eqs.~(\ref{eq:EI-eLDA}) and (\ref{eq:ind_HF-like_ener}), the individual
HF-like exchange does not depend explicitly on the weights, which means
that the above-mentioned variations originate from the eLDA correlation
functional [second and third terms on the right-hand side of
Eq.~(\ref{eq:EI-eLDA})]. If, for analysis purposes, we consider the
