(SNGDM), where the key issue is modelling trust weights among individuals. In social and …

A fundamental aspect of society is the exchange and discussion of opinions between
individuals, occurring in situations as varied as company boardrooms, elementary school …

In combination with social networks, opinion dynamics models can effectively describe the

Most of the distributed protocols for multi-agent consensus assume that the agents are

Large-scale group decision making is common in real-world scenarios, yet it involves two
critical issues:(1) clustering individuals into subgroups according to specific criterion, and (2) …

Opinion dynamics models have huge potential for understanding and addressing social
problems where solutions require the coordination of opinions, like anthropogenic climate …

The flow of information reaching us via the online media platforms is optimized not by the
information content or relevance but by popularity and proximity to the target. This is typically …

We present and analyse a model of opinion formation with dynamic confidence in agent-
mediated social networks where the profiling of agents as leaders or followers is possible …

In this paper, we investigate how the agent's self-confidence level and the node degree
influence the consensus opinion formation and the consensus convergence speed in the …

We present a new model of opinion changes dependent on the agents emotional state and
their information about the issue in question. Our goal is to construct a simple, yet nontrivial …
