2 SCC Decomposition

We consider subproblems for each of the 3 SCC(s) of the program graph.

2.1 SCC Subproblem 1/3

Here we consider the SCC { l8, l14 }.

2.1.1 Transition Removal

We remove transition 18 using the following ranking functions, which are bounded by 0.

l8: −2⋅x21 + 2⋅x25
l14: −2⋅x21 + 2⋅x25 + 1

2.1.2 Transition Removal

We remove transition 19 using the following ranking functions, which are bounded by 0.

l14: 0
l8: −1

2.1.3 Trivial Cooperation Program

There are no more "sharp" transitions in the cooperation program. Hence the cooperation termination is proved.

2.2 SCC Subproblem 2/3

Here we consider the SCC { l10, l9 }.

2.2.1 Transition Removal

We remove transition 16 using the following ranking functions, which are bounded by 0.

l10: x13
l9: x13

2.2.2 Transition Removal

We remove transition 11 using the following ranking functions, which are bounded by 0.

l9: x39
l10: 0

2.2.3 Trivial Cooperation Program

There are no more "sharp" transitions in the cooperation program. Hence the cooperation termination is proved.

2.3 SCC Subproblem 3/3

Here we consider the SCC { l4, l2 }.

2.3.1 Transition Removal

We remove transition 3 using the following ranking functions, which are bounded by 0.

l2: −1 + x10 + 3⋅x14 + 2⋅x16 + x39 + 4⋅x47x48x49 + 5⋅x51
l4: −1 + x10 + 3⋅x14 + 2⋅x16 + x39 + 4⋅x47x48x49 + 5⋅x51

2.3.2 Transition Removal

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

l4: 0
l2: −1

2.3.3 Trivial Cooperation Program

There are no more "sharp" transitions in the cooperation program. Hence the cooperation termination is proved.
