Discontinuous phase transitions in the multi-state noisy q-voter model: quenched vs. annealed disorder

Abstract: We introduce a generalized version of the noisy q-voter model, one of the most popular opinion dynamics models, in which voters can be in one of $$s \ge 2$$ s ≥ 2 states. As in the original binary q-voter model, which corresponds to $$s=2$$ s = 2 , at each update randomly selected vote… Show more

“…Several factors may facilitate discontinuous phase transitions, such as: (a) increasing the number of states that the system’s entities (agents, particles, etc.) can take 1 , 16 18 , (b) introducing an aversion to change, which can be related to the size of the group needed to influence the agent 19 , 20 or another kind of inertia 3 , 5 , (c) higher dimensionality of the system 21 , higher system degree 5 , or the larger number of layers in the multiplex 22 . Finally, the presence of the annealed instead of the quenched disorder usually promotes discontinuous phase transitions 23 26 .…”

“…On average, the fraction of voters that are always nonconformists is p, whereas the fraction of voters that are always conformists is 1 − p. This approach is considered in Refs. [6,13,15].…”

“…We assume that each of the active out-links may connect nodes of the same type τ independently of others with probability P (τ |τ, j; −j), given by one of Eqs. ( 10)- (13). Thus, the number of active out-links that connect nodes of the same type τ , y, is binomially distributed.…”
