I sifted through significant pile of papers related to the Wang-Landau algorithm and I still don't get why does it give correct result for the density of states.
I mean, the way it is presented in the papers, it looks quite arbitrary. On the start I have the partition function [tex]Z(\beta)=\sum_E \rho(E)e^{-\beta E}[/tex] and few paragraphs later I have the histogram [tex]h(E)[/tex] and the multipliers [tex]f[/tex].
I don't understand why when the histogram is going flat, the probability density goes to the equilibrium value and why is update of the density of states performed by multiplication with [tex]f[/tex].
