4 \item Nodes that may introduce cyclic iterations: grouped
5 \item Nodes inside each group: synchronized at each other
6 \item Nodes of distinct groups: keeping asynchronism
10 \item Group: SCC of the connection graph
11 \item Mixed iterations of DN with Uniform Delays:
13 \item $S_{ij}^t$ is $t$ if $i \in SCC(j)$.
16 \forall p_0,p_1,q_0,q_1,t \, .\,
18 p_1 \in SCC(p_0) \land
27 \item Elements in the same SCC: cannot be differentiated
