Wang Landau algorithm for entropic sampling of arch based microstates in the volume ensemble of static granular packings

We implement the Wang-Landau algorithm to sample with equal probabilities the static configurations of a model granular system. The "non-interacting rigid arch model" used is based on the description of static configurations by means of splitting the assembly of grains into sets of stable...
