Socioeconomic Interaction and Swings in Business Confidence Indicators
Martin Hohnisch, Sabine Pittnauer, Sorin Solomon +1
We propose a stochastic model of interactive formation of individual expectations regarding the business climate in an industry. Our model is motivated by a business climate survey…
Simple Simulation of Magnetic Structure for Nanoclusters
Ana Proykova, Dietrich Stauffer
A simple discrete model for magnetic structures of chromium nanoclusters, found with the help of local-spin DFT by Kohl and Bertsch, still confirms their conclusion that in most of…
Discretized opinion dynamics of Deffuant on scale-free networks
D. Stauffer, A. O. Sousa, C. Schulze
The consensus model of Deffuant et al is simplified by allowing for many discrete instead of infinitely many continuous opinions, on a directed Barabasi-Albert network. A simple sc…
Corrections to Finite Size Scaling in Percolation
P. M. C. de Oliveira, R. A. Nobrega, D. Stauffer
A 1/L-expansion for percolation problems is proposed, where L is the lattice finite length. The square lattice with 27 different sizes L = 18, 22 ... 1594 is considered. Certain sp…
Asymmetry in hierarchy model of Bonabeau et al
D. Stauffer, J. S. Sa Martins
The 1995 model of Bonabeau et al. explains the emergence of social hierarchies through randomness, but gives as many leaders as followers. A simple modification allows a more reali…
Simulation of Galam's contrarian opinions
D. Stauffer, J. S. Sa Martins
Galam's model of people voting always against the majority is shown to give for the quenched case different results than the original annealed model. For people diffusing on a latt…
