Threshold value of three dimensional bootstrap percolation
The following article deals with the critical value p_c of the
three-dimensional bootstrap percolation. We will check the behavior of p_c for
different lengths of the lattice and additionally we will scale p_c in the
limit of an infinite lattice.Comment: 8 pages including 9 figures for Int.J.Mod.Phys.
The Sznajd model of consensus building with limited persuasion
The Sznajd model, where two people having the same opinion can convince their
neighbours on the square lattice, is modified in the sense of Deffuant et al
and Hegselmann, that only neighbours of similar opinions can be convinced. Then
consensus is easy for the competition of up to three opinions but difficult for
four and more opinions.Comment: Two pages, no figures, Int. J. Mod. Phys. C 13, No.
The Penna Model of Biological Aging
This review deals with computer simulation of biological ageing, particularly
with the Penna model of 1995.Comment: 16-page invited review submitted to Bioinformatics and Biology

Simulation of Consensus Model of Deffuant et al on a Barabasi-Albert Network
In the consensus model with bounded confidence, studied by Deffuant et al.
(2000), two randomly selected people who differ not too much in their opinion
both shift their opinions towards each other. Now we restrict this exchange of
information to people connected by a scale-free network. As a result, the
number of different final opinions (when no complete consensus is formed) is
proportional to the number of people.Comment: 7 pages including 3 figs; Int.J.MOd.Phys.C 15, issue 2; programming

Justification of Sexual Reproduction by Modified Penna Model of Ageing
We generalize the standard Penna bit-string model of biological ageing by
assuming that each deleterious mutation diminishes the survival probability in
every time interval by a small percentage. This effect is added to the usual
lethal but age-dependent effect of the same mutation. We then find strong
advantages or disadvantages of sexual reproduction (with males and females)
compared to asexual cloning, depending on parameters.Comment: 4 pages, 2 figures, submitted to Physica
