Query: Exploring Replica-Exchange Wang-Landau sampling in higher-dimensional
  parameter space   We considered a higher-dimensional extension for the replica-exchange
Wang-Landau algorithm to perform a random walk in the energy and magnetization
space of the two-dimensional Ising model. This hybrid scheme combines the
advantages of Wang-Landau and Replica-Exchange algorithms, and the
one-dimensional version of this approach has been shown to be very efficient
and to scale well, up to several thousands of computing cores. This approach
allows us to split the parameter space of the system to be simulated into
several pieces and still perform a random walk over the entire parameter range,
ensuring the ergodicity of the simulation. Previous work, in which a similar
scheme of parallel simulation was implemented without using replica exchange
and with a different way to combine the result from the pieces, led to
discontinuities in the final density of states over the entire range of
parameters. From our simulations, it appears that the replica-exchange
Wang-Landau algorithm is able to overcome this difficulty, allowing exploration
of higher parameter phase space by keeping track of the joint density of
states.
