Outcome, a material that was found slightly earlier experimentally.  For structure prediction, \emph{Structure prediction} --  it has been commonly assumed that LDA/GGA is sufficient. Whereas comparisons between compounds with differing compositions certainly require the corrections detailed above, it is assumed that the systematic errors in LDA/GGA energies should cancel for differing structures of a *single* given composition. We argue this is not the case. In fact, correlations are important for comparison of energetics among structures for a single composition. We use USPEX to sample the local minima in the energy landscape of the Ba-Co-S-O system with the elements in a 1:1:1:1 ratio. We allow two formula units in a unit cell. We use VASP as our DFT engine. We use spin-polarized LDA/GGA and do not include U corrections. Around 300 k-points are used, with convergence criteria EDIFF=1e-6, NELM=40.
