Transitional probabilities P cn , P cc , P nn , P nc , P nm for λ = 2/3, μ= 3/4. Here we have P nn (u) > P nc (u) for u ∈ (0, u0) and, vice versa, P nn (u) <P nc (u) for u > u0. In this figure P cc (u) > P nn (u) for all u > 0, as 3λ ≤ 2μ + 1. The consensus is weak, since π c = 1/3. Since μ > λ, we have P cn (u) <P nm (u). This figure shows all simple cases that hold for any λ ∈ (0, 1), μ > 0, u > 0.
