The multiple histogram method has been adapted to treat distributions
of potential energies taken from classical molecular dynamics simulati
ons carried out at different total energies. For clusters with a Lenna
rd-Jones pairwise interaction, it is compared to the results of the or
iginal method, which was developed for constant temperature Monte Carl
o simulations. The same caloric curves are found in both cases. Since
the Monte Carlo algorithm is always cheaper, this makes it a method of
choice for studying clusters at thermodynamic equilibrium.
