Shennan-type evolution of stone-age cultural innovation
F. W. S. Lima, D. Stauffer
The computer simulations of Shennan (2001) are complemented by assuming the environment to change randomly. For moderate change rates, fitness optimisation through evolution is sti…
Love kills: Simulations in Penna Ageing Model
D. Stauffer, S. Cebrat, T. J. P. Penna +1
The standard Penna ageing model with sexual reproduction is enlarged by adding additional bit-strings for love: Marriage happens only if the male love strings are sufficiently diff…
Ising model simulation in directed lattices and networks
F. W. S. Lima, D. Stauffer
On directed lattices, with half as many neighbours as in the usual undirected lattices, the Ising model does not seem to show a spontaneous magnetisation, at least for lower dimens…
Positive mutations and mutation-dependent Verhulst factor in Penna ageing model
S. Moss de Oliveira, D. Stauffer, P. M. C de Oliveira +1
We twice modify the Penna model for biological ageing. First we introduce back (good) mutations and a memory for them into the model. It allows us to observe an improvement of the…
Concentration Gradient, Diffusion, and Flow Through Open Porous Medium Near Percolation Threshold via Computer Simulations
R. B. Pandey, J. F. Gettrust, D. Stauffer
The interacting lattice gas model is used to simulate fluid flow through an open percolating porous medium with the fluid entering at the source-end and leaving from the opposite e…
Spin Domains Generate Hierarchical Ground State Structure in J=+/-1 Spin Glasses
Guy Hed, Alexander K. Hartmann, Dietrich Stauffer +1
Unbiased samples of ground states were generated for the short-range Ising spin glass with Jij=+/-1, in three dimensions. Clustering the ground states revealed their hierarchical s…
