The exchange-correlation energy is studied using the density scaling proposed by Chan and Handy [G. K.-L. Chan and N. C. Handy, Phys. Rev. A 59, 2670 (1999)]. It is shown that there exists a value of the scaling factor for which the correlation energy disappears. The optimized potential method and the Krieger-Li-Iafrate approach are generalized to incorporate correlation.
