2 SCC Decomposition

We consider subproblems for each of the 4 SCC(s) of the program graph.

2.1 SCC Subproblem 1/4

Here we consider the SCC { l29, l15, l18, l30, l19, l14 }.

2.1.1 Transition Removal

We remove transition 48 using the following ranking functions, which are bounded by 0.

l14: x1x17
l15: x1x17
l19: −1 + x1x17
l18: −1 + x1x17
l29: −1 + x1x17
l30: −1 + x1x17

2.1.2 Transition Removal

We remove transitions 18, 44 using the following ranking functions, which are bounded by 0.

l14: 1
l15: 0
l19: 2
l18: 2
l29: 2
l30: 2

2.1.3 Transition Removal

We remove transition 45 using the following ranking functions, which are bounded by 0.

l18: −1 + x3x12
l19: −1 + x3x12
l29: −2 + x3x12
l30: −2 + x3x12

2.1.4 Transition Removal

We remove transitions 24, 41, 43, 42 using the following ranking functions, which are bounded by 0.

l18: 0
l19: −1
l29: 1
l30: 2

2.1.5 Trivial Cooperation Program

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

2.2 SCC Subproblem 2/4

Here we consider the SCC { l25, l22, l24, l21 }.

2.2.1 Transition Removal

We remove transition 33 using the following ranking functions, which are bounded by 0.

l21: x17 + x24
l22: x17 + x24
l24: −1 − x17 + x24
l25: −1 − x17 + x24

2.2.2 Transition Removal

We remove transitions 26, 29, 31, 30 using the following ranking functions, which are bounded by 0.

l21: 0
l22: −1
l24: 1
l25: 2

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 3/4

Here we consider the SCC { l10, l11, l13, l16, l12, l9 }.

2.3.1 Transition Removal

We remove transition 20 using the following ranking functions, which are bounded by 0.

l9: −1 + x1x18
l10: −1 + x1x18
l11: −1 + x1x18
l12: −1 + x1x18
l16: x1x18
l13: x1x18

2.3.2 Transition Removal

We remove transitions 36, 16 using the following ranking functions, which are bounded by 0.

l9: 2
l10: 2
l11: 2
l12: 2
l13: 1
l16: 0

2.3.3 Transition Removal

We remove transition 17 using the following ranking functions, which are bounded by 0.

l9: −2 + x3x13
l10: −1 + x3x13
l11: −2 + x3x13
l12: −1 + x3x13

2.3.4 Transition Removal

We remove transitions 13, 15, 14, 40 using the following ranking functions, which are bounded by 0.

l9: 2
l10: 1
l11: 3
l12: 0

2.3.5 Trivial Cooperation Program

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

2.4 SCC Subproblem 4/4

Here we consider the SCC { l5, l4, l3, l2 }.

2.4.1 Transition Removal

We remove transition 7 using the following ranking functions, which are bounded by 0.

l2: −1 − x18 + x23
l3: x18 + x23
l4: −1 − x18 + x23
l5: x18 + x23

2.4.2 Transition Removal

We remove transitions 3, 5, 4, 46 using the following ranking functions, which are bounded by 0.

l2: 2
l3: 1
l4: 3
l5: 0

2.4.3 Trivial Cooperation Program

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