The Wang-Landau method was proposed by F. Wang and D. P. Landau (Ref. 1) to compute the density of states, , of Potts models; where is the number of microstates of the system having energy .

The Wang-Landau method in its original version is a simulation technique designed to reach an uniform sampling of the energies of the system in a given range.
