12 SCC Decomposition

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

12.1 SCC Subproblem 1/2

Here we consider the SCC { 1, 5, 1_var_snapshot, 1*, 5_var_snapshot, 5* }.

12.1.1 Transition Removal

We remove transitions 5, 6 using the following ranking functions, which are bounded by −1.

12.1.2 Transition Removal

We remove transitions 16, 18, 7, 8 using the following ranking functions, which are bounded by −1.

12.1.3 Transition Removal

We remove transitions 30, 32 using the following ranking functions, which are bounded by −2.

12.1.4 Splitting Cut-Point Transitions

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

12.1.4.1 Cut-Point Subproblem 1/2

12.1.4.1.1 Splitting Cut-Point Transitions

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

12.1.4.2 Cut-Point Subproblem 2/2

12.1.4.2.1 Splitting Cut-Point Transitions

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

12.2 SCC Subproblem 2/2

Here we consider the SCC { 2, 6, 7, 2_var_snapshot, 2*, 6_var_snapshot, 6* }.

12.2.1 Transition Removal

We remove transitions 23, 25, 37, 39, 9, 10, 11, 12 using the following ranking functions, which are bounded by −2.

12.2.2 Transition Removal

We remove transition 13 using the following ranking functions, which are bounded by 5.

12.2.3 Splitting Cut-Point Transitions

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

12.2.3.1 Cut-Point Subproblem 1/2

12.2.3.1.1 Splitting Cut-Point Transitions

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

12.2.3.2 Cut-Point Subproblem 2/2

12.2.3.2.1 Splitting Cut-Point Transitions

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