Abstract

A method for calculation of the density of states of a system which combines the good statistical accuracy of transition matrix estimators with the rapid broad sampling of phase space generated by the Wang-Landau method is presented. This implementation requires only potential energy evaluations, and hence, is general to lattice and continuum systems. For the same reason and for the additional feature that the transition matrix presserves information from the complete simulation, the method is computationally efficient.
