Pp. Nidras et R. Brak, NEW MONTE-CARLO ALGORITHMS FOR INTERACTING SELF-AVOIDING WALKS, Journal of physics. A, mathematical and general, 30(5), 1997, pp. 1457-1469
In this paper we present two new Monte Carlo algorithms for simulating
interacting self-avoiding walks. These algorithms are built on the Be
rretti-Sokal and reptation algorithms for simulating non-interacting s
elf-avoiding walks respectively by adding a Metropolis step. We enhanc
e each algorithm by introducing special local moves. In addition, the
reptation algorithm is further enhanced by running the simulations as
a multiple Markov chain. Each of these algorithms are studied here thr
ough an analysis of their autocorrelation properties. In the case of t
he Berretti-Sokal algorithm an increase in efficiency by a factor of a
round 40 is achieved for non-interacting self-avoiding walks.
