Wang-Landau Sampling is a monte carlo technique to measure the (energy)-density of states of a system. From this, other thermodynamic properties can be obtained. The technique is especially interesting for systems which have states that are rarely sampled with conventional monte carlo methods because they are "hidden" behind an energy barrier.
