2 SCC Decomposition

We consider subproblems for each of the 7 SCC(s) of the program graph.

2.1 SCC Subproblem 1/7

Here we consider the SCC { l22, l21 }.

2.1.1 Transition Removal

We remove transition 27 using the following ranking functions, which are bounded by 0.

l21: 149 − x11
l22: 149 − x11

2.1.2 Transition Removal

We remove transition 31 using the following ranking functions, which are bounded by 0.

l22: 0
l21: −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 2/7

Here we consider the SCC { l20, l18, l17, l19 }.

2.2.1 Transition Removal

We remove transition 25 using the following ranking functions, which are bounded by 0.

l17: 48 − x12
l18: 49 − x12
l19: 48 − x12
l20: 49 − x12

2.2.2 Transition Removal

We remove transition 22 using the following ranking functions, which are bounded by 0.

l17: 1
l18: −1
l19: 1
l20: −1

2.2.3 Transition Removal

We remove transition 23 using the following ranking functions, which are bounded by 0.

2.2.4 Transition Removal

We remove transitions 33, 32 using the following ranking functions, which are bounded by 0.

l19: 1
l17: 0
l18: 1
l20: 0

2.2.5 Trivial Cooperation Program

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

2.3 SCC Subproblem 3/7

Here we consider the SCC { l1, l3, l0, l2 }.

2.3.1 Transition Removal
