Membranes are presented by parallel plane surfaces ...
Harvard University, Cambridge, Massachusetts, USA(Received 29 July 2019; accepted 31 January 2020; published 6 March 2020)We show that the Wang-Landau algorithm can be formulated as a stochastic gradient descent algorithm
also we have to find the execution time of the factorial program. Before going to write the Pyt...
We present a modified Wang-Landau algorithm for models with continuous degrees of freedom. We demonstrate this algorithm with the calculation of the joint density of states of ferromagnet Heisenberg models and a model polymer chain. The joint density of states contains more information than the densi...
A two-step Monte Carlo procedure is developed to investigate the dimerization process of the homodimer glycophorin A. In the first step, the energy density of states of the system is estimated by the Wang–Landau algorithm. In the second step, a production run is performed during which various...

respect to this new algorithm and a performance of the algorithm comparable in efficiency to the transition matrix Monte Carlo methods is reached. In sec. 2, the flat histogram method of Wang and Landau [12] is briefly re-
The model is studied in both its first- and second-order phase transition regime for several values of the crystal field via a sophisticated two-stage numerical strategy using the Wang-Landau algorithm. Using classical finite-size scaling techniques we estimate with high accuracy phase-transition ...
Results: A non-Boltzmannian Monte Carlo algorithm was designed by Wang and Landau to estimate the density of states for complex systems, such as the Ising model, that exhibit a phase transition. In this article, we apply the Wang-Landau (WL) method to compute the density of states for sec...
