 In the Linear Voter Model, nodes can be either \emph{red} or \emph{blue}.
 Without loss of generality, we can suppose that the \emph{blue} nodes are
 contagious. The parameters of the graph are normalized such that $\forall i, \
-\sum_j \Theta_{i,j} = 1$ and we assume that $\Theta_{i,i}$ is always non-zero,
-meaning that all nodes have self-loops.  Each round, every node $j$
+\sum_j \Theta_{i,j} = 1$.  Each round, every node $j$
 independently chooses one of its neighbors with probability $\Theta_{i,j}$ and
 adopts their color. The cascades stops at a fixed horizon time $T$ or if all
 nodes are of the same color.  If we denote by $X^t$ the indicator variable of
