Mean-field approximation and phase transitions in an Ising-voter model on directed regular random graphs
Adam Lipowski, Antonio Luis Ferreira, Dorota Lipowska +1
It is known that on directed graphs, the correlations between neighbours of a given site vanish and thus simple mean-field-like arguments can be used to describe exactly the behavi…
Heat-Bath and Metropolis Dynamics in Ising-like Models on Directed Regular Random Graphs
Adam Lipowski, Antonio L. Ferreira, Dorota Lipowska
Using a single-site mean-field approximation (MFA) and Monte Carlo simulations, we examine Ising-like models on directed regular random graphs. The models are directed-network impl…
Accurate Estimate of the Joint Density of States via Flat Scan Sampling
J. C. Inácio, A. L. Ferreira, J. S. Amaral
A Monte Carlo method to estimate the Joint Density of States g(E,M) of the Ising and Ising-like models is presented. The method is applied to the well-known 2D Ising model, and is…
Phase transition and power-law coarsening in Ising-doped voter model
Adam Lipowski, Dorota Lipowska, Antonio L. Ferreira
We examine an opinion formation model, which is a mixture of Voter and Ising agents. Numerical simulations show that even a very small fraction () of the Ising agents dra…
Prisoner's dilemma on directed networks
A. L. Ferreira, A. Lipowski, T. B. Pedro +2
We study the prisoner's dilemma model with a noisy imitation evolutionary dynamics on directed out-homogeneous and uncorrelated directed random networks. An heterogeneous pair mean…
Agreement dynamics on directed random graphs
Adam Lipowski, Dorota Lipowska, Antonio L. Ferreira
We examine some agreement-dynamics models that are placed on directed random graphs. In such systems a fraction of sites , where is the average degree, becomes perman…
