Collapsed 2-Dimensional Polymers on a Cylinder
Hsiao-Ping Hsu, Peter Grassberger
Single partially confined collapsed polymers are studied in two dimensions. They are described by self-avoiding random walks with nearest-neighbour attractions below the -point,…
A Growth-based Optimization Algorithm for Lattice Heteropolymers
Hsiao-Ping Hsu, Vishal Mehra, Walter Nadler +1
An improved version of the pruned-enriched-Rosenbluth method (PERM) is proposed and tested on finding lowest energy states in simple models of lattice heteropolymers. It is found t…
Reply to ``Comments on Kullback-Leibler and renormalized entropies: Applications to electroencephalograms of epilepsy patients"
R. Quian Quiroga, J. Arnhold, K. Lehnertz +1
Kopitzki et al (preceeding comment) claim that the relationship between Renormalized and Kullback-Leibler entropies has already been given in their previous papers. Moreover, they…
Growth Algorithms for Lattice Heteropolymers at Low Temperatures
Hsiao-Ping Hsu, Vishal Mehra, Walter Nadler +1
Two improved versions of the pruned-enriched-Rosenbluth method (PERM) are proposed and tested on simple models of lattice heteropolymers. Both are found to outperform not only the…
Data Compression and Entropy Estimates by Non-sequential Recursive Pair Substitution
Peter Grassberger
We argue that Non-sequential Recursive Pair Substitution (NSRPS) as suggested by Jiménez-Montaño and Ebeling can indeed be used as a basis for an optimal data compression algorithm…
Heat Conduction in Low Dimensions: From Fermi-Pasta-Ulam Chains to Single-Walled Nanotubes
P. Grassberger, L. Yang
Heat conduction in 1-dimensional anharmonic systems is anomalous in the sense that the conductivity κscales with a positive power of the system size, κ~ L^α. In two dimensions, pre…
Entropy estimation of symbol sequences
Thomas Schürmann, Peter Grassberger
We discuss algorithms for estimating the Shannon entropy h of finite symbol sequences with long range correlations. In particular, we consider algorithms which estimate h from the…
Heat Conduction and Entropy Production in a One-Dimensional Hard-Particle Gas
Peter Grassberger, Walter Nadler, Lei Yang
We present large scale simulations for a one-dimensional chain of hard-point particles with alternating masses. We correct several claims in the recent literature based on much sma…
Event synchronization: a simple and fast method to measure synchronicity and time delay patterns
R. Quian Quiroga, T. Kreuz, P. Grassberger
We propose a simple method to measure synchronization and time delay patterns between signals. It is based on the relative timings of events in the time series, defined e.g. as loc…
Critical Percolation in High Dimensions
Peter Grassberger
We present Monte Carlo estimates for site and bond percolation thresholds in simple hypercubic lattices with 4 to 13 dimensions. For d<6 they are preliminary, for d >= 6 they are b…
Critical Behaviour of the Drossel-Schwabl Forest Fire Model
Peter Grassberger
We present high statistics Monte Carlo results for the Drossel-Schwabl forest fire model in 2 dimensions. They extend to much larger lattices (up to ) than previ…
Go with the Winners: a General Monte Carlo Strategy
P. Grassberger
We describe a general strategy for sampling configurations from a given distribution, NOT based on the standard Metropolis (Markov chain) strategy. It uses the fact that nontrivial…
