The problem of reaching an agreement in a multiagent system has been widely investigated. Opinion Dynamics is a similar problem where agents are assumed to interact in order to reach an agreement on their opinion. The key aspect of this formulation is that the time-varying network topology describing the interaction among agents is defined according ...

International Journal of Knowledge and Systems Science, 2011
As a key sub-field of social dynamics and sociophysics, opinion dynamics utilizes mathematical and physical models and the agent-based computational modeling tools, to investigate the spreading of opinions in a collection of human beings. This research field stems from various disciplines in social sciences, especially the social influence models ...

DYNAMICS OF NETWORKS AND OPINIONS
International Journal of Bifurcation and Chaos, 2007Social relations between people seldom follow regular lattice structures. In the Barabási–Albert model nodes link to the existing network structure with a probability proportional to the number of nodes previously attached. Here, we present an anthropologically motivated interpolation between Erdös–Rényi and Barabási–Albert rules, where people also ...

Dynamic Opinion Representation
Scandinavian Political Studies, 1997Two models of opinion change in a representative democracy are subjected to an empirical test based on data from a series of surveys with voters and members of parliament in Sweden covering the period 1968–1994. An elite‐driven opinion model proved to fit the data better than a mass‐driven model.

Opinion dynamics in relative-opinion-dependent networks
2017 36th Chinese Control Conference (CCC), 2017This paper investigates the asymptotic behavior of opinion dynamics in relative-opinion-dependent networks, which is motivated by the observation that a social agent tends to accept opinions close to itself. That is, the interpersonal influence between social agents decreases gradually in their relative opinion.

Abstract The opinion dynamics studies how a final consensus emerges from a diversified initial configuration. The final result can be an artifact arising in the voting processes and overlook the features of the initial configuration, which leads to the unfair result.

State-dependent opinion dynamics
2014 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2014We study the simultaneous evolution of the opinion profile and network topology of a system of N agents. Based on the opinion profile at any given time, agents probabilistically decide which other agents to form links with. The probability of a link being formed with another agent depends on both similarity of their opinions and the popularity of that ...

Discrete-time opinion dynamics
2011 Conference Record of the Forty Fifth Asilomar Conference on Signals, Systems and Computers (ASILOMAR), 2011We discuss the Hegselmann-Krause model for opinion dynamics in discrete-time for a symmetric confidence bound. We construct an adjoint dynamics and use it to define a Lyapunov comparison function that decreases along the trajectory of the opinion dynamics. Using the Lyapunov comparison function, we develop a novel upper bound on the convergence time of
