Effects of neutral selection on the evolution of molecular species
M. E. J. Newman, Robin Engelhardt
We introduce a new model of evolution on a fitness landscape possessing a tunable degree of neutrality. The model allows us to study the general properties of molecular species und…
Monte Carlo simulation of ice models
G. T. Barkema, M. E. J. Newman
We propose a number of Monte Carlo algorithms for the simulation of ice models and compare their efficiency. One of them, a cluster algorithm for the equivalent three colour model,…
New Monte Carlo algorithms for classical spin systems
G. T. Barkema, M. E. J. Newman
We describe a number of recently developed cluster-flipping algorithms for the efficient simulation of classical spin models near their critical temperature. These include the algo…
Diffusion constant for the repton model of gel electrophoresis
M. E. J. Newman, G. T. Barkema
The repton model is a simple model of the "reptation" motion by which DNA diffuses through a gel during electrophoresis. In this paper we show that the model can be mapped onto a s…
A model of mass extinction
M. E. J. Newman
A number of authors have in recent years proposed that the processes of macroevolution may give rise to self-organized critical phenomena which could have a significant effect on t…
Comment on "Self-organized criticality in living systems" by C. Adami
M. E. J. Newman, Simon M. Fraser, Kim Sneppen +1
Following extensive numerical experiments, it has been suggested that the evolution of competing computer programs in artificial life simulations shows signs of being a self-organi…
