Modelling and Simulating Extreme Opinion Diffusion

This paper focuses on modelling and simulating diffusion of extreme opinions among agents. In this work, opinions are modelled as formulas of the propositional logic. Moreover, agents influence each other and any agent changes its current opinion by merging the opinions of its influencers, taking into account the strength of their influence. We propose several definitions of extreme opinions and extremism. Formal studies of these definitions are made as well as some simulations.
