Indifferents as an interface between Contra and Pro (2009)
Malarz, Krzysztof, Kulakowski, Krzysztof
In most sociophysical simulations on public opinion, only two opinions are allowed: Pro and Contra. However, in all political elections many people do not vote. Here we analyse two models of dynamics...
Zaller-Deffuant model of public opinion (2009)
Malarz, Krzysztof, Gronek, Piotr, Kulakowski, Krzysztof
Recent formulation of the Zaller model of mass opinion is generalized to include the interaction between agents. The mechanism of interaction is close to the bounded confidence model. The outcome of...
Clusterization, frustration and collectivity in random networks (2007)
Manka, Anna, Malarz, Krzysztof, Kulakowski, Krzysztof
We consider the random Erd{\H o}s--R\'enyi network with enhanced clusterization and Ising spins $s=\pm 1$ at the network nodes. Mutually linked spins interact with energy $J$. Magnetic properties of...
Search for bottleneck effects in Penna ageing and Schulze language model (2006)
Malarz, Krzysztof, Stauffer, Dietrich
No influence was seen when in two models with memory effects the populations were drastically decreased after equilibrium was established, and then allowed to increase again.
2nd Polish Symposium on Econo- and Sociophysics (2006)
Burda, Zdzislaw, Holyst, Janusz, Jurkiewicz, Jerzy, Kulakowski, Krzysztof, Malarz, Krzysztof, Nowak, Maciej A, ...
Restoring site percolation on a damaged square lattice (2004)
Galam, Serge, Malarz, Krzysztof
We study how to restore site percolation on a damaged square lattice with nearest neighbor (N$^2$) interactions. Two strategies are suggested for a density $x$ of destroyed sites by a random attack...
SEARCH FOR BOTTLENECK EFFECTS IN PENNA AGEING AND SCHULZE LANGUAGE MODEL
KRZYSZTOF MALARZ, DIETRICH STAUFFER
No influence was seen when in two models with memory effects the populations were drastically decreased after equilibrium was established, and then allowed to increase again.
