A Simple Method to Make the Wang-Landau Sampling Converge
  We show that a histogram maintained throughout the Wang-Landau (WL) sampling for the energy entries visited during the simulation could be used to make the simulated density of states (DOS) converge. The method is easy to be implemented to the WL sampling with no extra computational cost and bears the advantages of both the WL method and the multicanonical method.
