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 { 1, 3, 4, 5, 7, 8, 9, 10, 1_var_snapshot, 1* }.

8.1.1 Transition Removal

We remove transition 14 using the following ranking functions, which are bounded by −92.

1:	1 − 10⋅i_0
3:	−7 − 10⋅i_0
4:	−5 − 10⋅i_0
5:	−6 − 10⋅i_0
7:	−4 − 10⋅i_0
8:	−3 − 10⋅i_0
9:	−2 − 10⋅i_0
10:	−1 − 10⋅i_0
1_var_snapshot:	−10⋅i_0
1*:	2 − 10⋅i_0

8.1.2 Transition Removal

We remove transitions 29, 31, 2, 3, 4, 6, 7, 8, 9, 10, 11, 12, 16 using the following ranking functions, which are bounded by −9.

1:	−7
3:	−5
4:	−3
5:	−4
7:	−2
8:	−1
9:	0
10:	−9

8.1.3 Splitting Cut-Point Transitions

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

8.1.3.1 Cut-Point Subproblem 1/1

Here we consider cut-point transition 28.

8.1.3.1.1 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 { 0, 2, 6, 12, 13, 14, 15, 16, 6_var_snapshot, 6* }.

8.2.1 Transition Removal

We remove transition 1 using the following ranking functions, which are bounded by −90.

0:	1 − 10⋅i_0
2:	−10⋅i_0
6:	3 − 10⋅i_0
12:	−5 − 10⋅i_0
13:	−3 − 10⋅i_0
14:	−4 − 10⋅i_0
15:	−2 − 10⋅i_0
16:	−1 − 10⋅i_0
6_var_snapshot:	2 − 10⋅i_0
6*:	4 − 10⋅i_0

8.2.2 Transition Removal

We remove transitions 36, 38, 5, 15, 17, 18, 19, 20, 21, 22, 23, 24, 25 using the following ranking functions, which are bounded by −9.

2:	0
6:	−7
12:	−5
13:	−3
14:	−4
15:	−2
16:	−1
6_var_snapshot:	−8

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 35.

8.2.3.1.1 Splitting Cut-Point Transitions

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