8 SCC Decomposition

We consider subproblems for each of the 2 SCC(s) of the program graph.

8.1 SCC Subproblem 1/2

Here we consider the SCC { 2, 2_var_snapshot, 2* }.

8.1.1 Transition Removal

We remove transitions 17, 19, 6, 7 using the following ranking functions, which are bounded by 2.

2:	2 + 3⋅arg1
2_var_snapshot:	3⋅arg1
2*:	4 + 3⋅arg1

8.1.2 Splitting Cut-Point Transitions

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 16.

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 { 1, 1_var_snapshot, 1* }.

8.2.1 Transition Removal

We remove transitions 1, 2, 3, 4 using the following ranking functions, which are bounded by 2.

1:	1 − 3⋅arg3 + 3⋅arg4
1_var_snapshot:	−3⋅arg3 + 3⋅arg4
1*:	2 − 3⋅arg3 + 3⋅arg4

8.2.2 Transition Removal

We remove transitions 10, 12 using the following ranking functions, which are bounded by −1.

1:	0
1_var_snapshot:	− arg1P
1*:	arg1P

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 9.

8.2.3.1.1 Splitting Cut-Point Transitions

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