Struct OpinionDynamics 

Source 
pub struct OpinionDynamics {
    pub epsilon: f64,
    pub mu: f64,
}
Expand description

Deffuant-Weisbuch bounded confidence opinion dynamics.

Agents update opinions toward each other only when |o_i - o_j| < ε. Update: o_i += μ(o_j - o_i), o_j += μ(o_i - o_j).

Fields§

§epsilon: f64

Confidence bound ε: agents interact only when |o_i - o_j| < epsilon.

§mu: f64

Convergence parameter μ ∈ (0, 0.5].

Implementations§

Source§

impl OpinionDynamics

Source

pub fn new(epsilon: f64, mu: f64) -> Self

Creates a new Deffuant-Weisbuch model.

Source

pub fn run(&self, opinions: &mut Vec<f64>, steps: usize, seed: u64)

Runs steps of the Deffuant model on opinions (modified in place).

At each step a random pair is chosen; if they are within ε they converge.

Source

pub fn count_clusters(&self, opinions: &[f64]) -> usize

Returns the number of opinion clusters (groups within ε/2 of each other).
