We consider 1 subproblems corresponding to sets of cut-point transitions as follows.

8.1.2.1 Cut-Point Subproblem 1/1

Here we consider cut-point transition 18.

8.1.2.1.1 Splitting Cut-Point Transitions

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

8.2 SCC Subproblem 2/2

Here we consider the SCC { 7, 7_var_snapshot, 7* }.

8.2.1 Transition Removal

We remove transitions 9, 10, 11, 12, 13 using the following ranking functions, which are bounded by 3.

 7: 1 + 4⋅arg2 7_var_snapshot: 4⋅arg2 7*: 2 + 4⋅arg2

8.2.2 Transition Removal

We remove transitions 26, 28 using the following ranking functions, which are bounded by −1.

 7: 0 7_var_snapshot: −1 7*: 1

8.2.3 Splitting Cut-Point Transitions

We consider 1 subproblems corresponding to sets of cut-point transitions as follows.

8.2.3.1 Cut-Point Subproblem 1/1

Here we consider cut-point transition 25.

8.2.3.1.1 Splitting Cut-Point Transitions

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