    • If we include self-edges, the strength (weighted degree) of each node will increase by 1. This, in turn, leads to a constant increase in the expected edge weight in the null model. For a network with self-edges, the expected edge weight is given by ij s =n/ [2 (n+2)], a shift by a constant value of ij s - pij =2/ [n (n+2)] ≈1.62× 10-4 relative to the network in which self-edges are excluded. Self-edges always occur within a community, so they will always contribute to the summation in Eq. irrespective of exactly how the nodes are partitioned into communities. This implies that self-edges play no role when selecting the community partition that minimizes the interaction energy at a particular resolution.
