Deep Learning of the Biswas-Chatterjee-Sen Model
J. F. Silva Neto, D. S. M. Alencar, L. T. Brito +5
We investigate the critical properties of kinetic continuous opinion dynamics using deep learning techniques. The system consists of continuous spin variables in the interval $…
Supervised and Unsupervised Deep Learning Applied to the Majority Vote Model
J. F. Silva Neto, D. S. M. Alencar, L. T. Brito +5
We employ deep learning techniques to investigate the critical properties of the continuous phase transition in the majority vote model. In addition to deep learning, principal com…
Generalized Diffusive Epidemic Process with Permanent Immunity in Two Dimensions
V. R. Carvalho, T. F. A. Alves, G. A. Alves +4
We introduce the generalized diffusive epidemic process, which is a metapopulation model for an epidemic outbreak where a non-sedentary population of walkers can jump along lattice…
Social dilemmas, network reciprocity and the small-world property
F. B. Pereira, R. S. Ferreira, D. S. M. Alencar +4
We revisit two evolutionary game theory models, namely the Prisoner and the Snowdrift dilemmas, on top of small-world networks. These dynamics on networked populations (individuals…
Critical Short-Time Behavior of Majority-Vote Model on Scale-Free Networks
D. S. M. Alencar, J. F. S. Neto, T. F. A. Alves +4
We discuss the short-time behavior of the majority vote dynamics on scale-free networks at the critical threshold. We introduce a heterogeneous mean-field theory on the critical sh…
Estimating thresholds for asynchronous susceptible-infected-removed model on complex networks
D. S. M. Alencar, T. F. A. Alves, F. W. S. Lima +3
We use the pair heterogeneous mean-field (PHMF) approximation for an asynchronous version of the susceptible-infected-removed (SIR) model to estimate the epidemic thresholds on com…
Droplet Finite-Size Scaling of the Majority Vote Model on Quenched Scale-Free Networks
D. S. M. Alencar, T. F. A. Alves, F. W. S. Lima +3
We consider the Majority Vote model coupled with scale-free networks. Recent works point to a non-universal behavior of the Majority Vote model, where the critical exponents depend…
Epidemic Outbreaks on Quenched Scale-Free Networks
D. S. M. Alencar, T. F. A. Alves, F. W. S. Lima +3
We present a finite-size scaling theory of a contact process with permanent immunity on uncorrelated scale-free networks. We model an epidemic outbreak by an analog of the suscepti…
Phase Diagram of the Contact Process on Barabasi-Albert Networks
D. S. M. Alencar, T. F. A. Alves, G. A. Alves +3
We show results for the contact process on Barabasi networks. The contact process is a model for an epidemic spreading without permanent immunity that has an absorbing state. For f…
Modified Epidemic Diffusive Process on the Apollonian Network
D. S. M. Alencar, A. Macedo-Filho, T. F. A. Alves +3
We present an analysis of an epidemic spreading process on the Apollonian network that can describe an epidemic spreading in a non-sedentary population. The modified diffusive epid…
