Chaos in social learning with multiple true states

Fang, Aili; Wang, Lin; Zhao, Jiuhua; Wang, Xiaofan - In: Physica A: Statistical Mechanics and its Applications 392 (2013) 22, pp. 5786-5792

Most existing social learning models assume that there is only one underlying true state. In this work, we consider a social learning model with multiple true states, in which agents in different groups receive different signal sequences generated by their corresponding underlying true states....

Analytic treatment of consensus achievement in the single-type zealotry voter model

Fudolig, Mikaela Irene D.; Esguerra, Jose Perico H. - In: Physica A: Statistical Mechanics and its Applications 413 (2014) C, pp. 626-634

We introduce zealots of one opinion in the voter model on a complete graph and examine how they affect consensus … achievement. Using first-step analysis for Markov chains to obtain an exact solution, we find that the mean consensus time scales … with the population size N. Increasing the number of zealots, Z, will decrease the consensus time in a power law fashion …

The role of persuasion power on the consensus formation

Gündüç, Semra; Eryiğit, Recep - In: Physica A: Statistical Mechanics and its Applications 426 (2015) C, pp. 16-24

An opinion dynamics model which is based on a version of two dimensional Sznajd model is introduced. According to this model the dynamics is governed by the interactions between four agents which live on the corners of a plaquette and their neighbors. The distinctive feature of the model is that...

Impact of degree mixing pattern on consensus formation in social networks

Liu, Xiao Fan; Tse, Chi Kong - In: Physica A: Statistical Mechanics and its Applications 407 (2014) C, pp. 1-6

The consensus formation process in a social network is affected by a number of factors. This paper studies how the … degree mixing pattern of a social network affects the consensus formation process. A social network of more than 50,000 nodes … group. The DeGroot model is used to simulate the consensus formation processes in the network. Simulation suggests that the …
