### 14 SCC Decomposition

We consider subproblems for each of the 4 SCC(s) of the program graph.

### 14.1 SCC Subproblem 1/4

Here we consider the SCC { 4, 15, 4_var_snapshot, 4* }.

We consider 2 subproblems corresponding to sets of cut-point transitions as follows.

### 14.3.4.1 Cut-Point Subproblem 1/2

Here we consider cut-point transition 39.

### 14.3.4.1.1 Splitting Cut-Point Transitions

There remain no cut-point transition to consider. Hence the cooperation termination is trivial.

Here we consider cut-point transition 46.

### 14.3.4.2.1 Splitting Cut-Point Transitions

There remain no cut-point transition to consider. Hence the cooperation termination is trivial.
