6 SCC Decomposition

We consider subproblems for each of the 1 SCC(s) of the program graph.

6.1 SCC Subproblem 1/1

Here we consider the SCC { 4, 5, 4_var_snapshot, 4* }.

6.1.1 Transition Removal

We remove transition 4 using the following ranking functions, which are bounded by 0.

4:	−2 − 4⋅i_17_0 + 4⋅length_16_0
5:	−4⋅i_17_0 + 4⋅length_16_0
4_var_snapshot:	−3 − 4⋅i_17_0 + 4⋅length_16_0
4*:	−1 − 4⋅i_17_0 + 4⋅length_16_0

6.1.2 Transition Removal

We remove transitions 10, 12, 5 using the following ranking functions, which are bounded by −1.

4:	0
5:	2
4_var_snapshot:	−1
4*:	1

6.1.3 Splitting Cut-Point Transitions

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

6.1.3.1 Cut-Point Subproblem 1/1

Here we consider cut-point transition 9.

6.1.3.1.1 Splitting Cut-Point Transitions

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