A Modified Histogram Method for Disordered Lattices
  A new method is developed to extend the histogram method to lattices with any type of disorder. The Monte Carlo single- and multiple-histogram methods were developed to get the most out of only a few simulations, but are restricted to simulations with identical lattice configurations. The method introduced here expands on the histogram method to allow data from various disordered lattice configurations to be optimally combined in a single weighted average result. This method is applied to a simple Ising-like model of the relaxor ferroelectric perovskite solid solution $BaTiO_3$ - $Bi(Zn_{1/2}Ti_{1/2})O_3$ (BT-BZT), in which disorder plays a pivotal role.
