Stochastic blockmodel network with additional leaves.
Final network parameters after leaf addition: n = 1273, m = 1818, cin = 4.8, cout = 1.2, where n denotes the number of nodes in the network and m denotes the number of undirected edges in the network. All the random walk operators are square matrices of order 2m. (a) Eigenvalues of a representative non-backtracking matrix B. Note that there is only one real eigenvalue outside the bulk. (b) Eigenvalues of a representative reluctant backtracking matrix R.
