Voter Model and Biased Voter Model in Heterogeneous Environments
With the rapid adoption of transgenic crops, gene flow from transgenic crops to wild relatives through pollen dispersal is of significant concern andwarrants both empirical and theoretical studies to assess the risk of introduction of transgenes into wild populations. We propose to use the (biased) voter model in a heterogeneous environment to investigate the effects of recurrent gene flow from...
متن کاملNonlinear q-voter model.
We introduce a nonlinear variant of the voter model, the q-voter model, in which q neighbors (with possible repetition) are consulted for a voter to change opinion. If the q neighbors agree, the voter takes their opinion; if they do not have a unanimous opinion, still a voter can flip its state with probability epsilon . We solve the model on a fully connected network (i.e., in mean field) and ...
متن کاملNonlinear $q$-voter model with inflexible zealots
We study the dynamics of the nonlinear q-voter model with inflexible zealots in a finite well-mixed population. In this system, each individual supports one of two parties and is either a susceptible voter or an inflexible zealot. At each time step, a susceptible adopts the opinion of a neighbor if this belongs to a group of q≥2 neighbors all in the same state, whereas inflexible zealots never ...
متن کاملProbabilistic Rejectionless Anti-Voter Optimization Algorithm
A new probabilistic algorithm, called Probabilistic Rejectionless Anti-Voter (PRAV), is introduced. Due to its property to concentrate computational efforts on places where there are the greatest chances for the improvement of an objective function and due to the employed rejectionless mechanism a significant speed-up over other probabilistic methods is achieved The extensive superior experimen...
متن کاملVoter model on heterogeneous graphs.
We study the voter model on heterogeneous graphs. We exploit the nonconservation of the magnetization to characterize how consensus is reached. For a network of N nodes with an arbitrary but uncorrelated degree distribution, the mean time to reach consensus T(N) scales as Nmu(2)1/mu(2), where mu(k) is the kth moment of the degree distribution. For a power-law degree distribution n(k) approximat...
