Agents interact only if |x_i − x_j| < ε; converge to shared opinion · phase transition at ε ≈ 0.5
Clusters: —
Steps: 0
Converged: No
Deffuant et al. (2000): randomly paired agents with opinions within ε of each other pull toward each other by fraction μ.
Critical threshold: ε > 0.5 → global consensus; ε < 0.5 → fragmentation into ~1/(2ε) clusters.
The trajectory plot shows every agent's opinion over time — watch polarization emerge.
