Abstract: We discuss the recent application to strongly disordered systems of the Critical Minimum Energy Subspace (CrMES) method, used to limit the energy subspace of the Wang–Landau sampling. We compare with our results on the 3D random field Ising model obtained by a multi-range Wang–Landau simulation over the whole energy range. We point out some problems that may arise when applying the CrMES scheme to models having a complex free energy landscape.
