The convergence speed of the algorithm is tightly tied to the connectivity properties of the underlying random walk. As such, we propose an efficient random walk that uses geometrical information to circumvent the following inherent difficulties: avoiding overstepping strata, toning down concentration ...

finding the factorial of a large number. A large number will be provided by the user and we have to calculate the factorial of a number, also we have to find the execution time of the factorial program. Before going to write the Python program, we will try to understand the algorithm.

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...

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 ...
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-
