Opinion dynamics have attracted the interest of researchers from different fields. Local
interactions among individuals create interesting dynamics for the system as a whole. Such …

Interest in group decision-making (GDM) has been increasing prominently over the last
decade. Access to global databases, sophisticated sensors which can obtain multiple inputs …

Consensus reaching is an iterative and dynamic process that supports group decision-
making models by guiding decision-makers towards modifying their opinions through a …

Opinion dynamics (OD) models, which simulate individuals' opinion evolution process on
social network to analyze the final state of opinion distribution in a group, usually differ from …

The data of online public opinion updates quickly and new information plays a greater role
than old information, this paper proposes a novel new information variable weight fractional …

Many consensus models in social network group decision making (SNGDM) have been
reported to obtain a collective solution despite the initial opinions of decision makers (DMs) …

Most existing opinion formation processes apply one opinion dynamics model. However,
this article combines opinion formation and complex networks to innovatively develop two …

Opinion evolution is a common phenomenon in social network group decision-making
(SNGDM), where the key issue is modelling trust weights among individuals. In social and …

In this paper, we consider discrete opinion dynamics with n possible opinions in social
networks with stubborn agents, where conformists adopt the most common opinions in their …

To manage consensus in opinion dynamics models (ODMs), removing bias from agents'
interactions and considering their willingness are critical. It can be accomplished by …
