It is well-established that within the DFT+U framework, one can achieve several self-consistent solutions with greatly varying energies for the same exact magnetic ordering. In 2010, Meredig et al. showed that a relatively simply "U-ramping" method could be employed to more easily identify the true ground state solution for troublesome DFT+U cases.

Since it has been over a decade since the aforementioned paper, is this still considered to be the optimal approach when carrying out DFT+U calculations? Are there any other methods commonly used to identify the ground state solution when carrying out DFT+U calculations?
