<h3>Dynamics</h3>

Convergence rates are computed over the time span marked in blue in the first plot.

**Parameters:**

- $\mu$: LFR mixing parameter
- $T^*$: time to consensus = $-1/\log(\vert\lambda_2\vert) \cdot \delta t$, where $\lambda_2$ is the second largest eigenvalue of the transition matrix for the associated time discrete model. See [here](https://doi.org/10.1016/j.ins.2019.02.028).
- [assortativity](https://en.wikipedia.org/wiki/Assortativity)
- [clustering coeff.](https://en.wikipedia.org/wiki/Clustering_coefficient)
