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 { l22, l21 }.

2.1.1 Transition Removal

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

l21: −2⋅x4 + 2⋅x8 + 1
l22: −2⋅x4 + 2⋅x8

2.1.2 Transition Removal

We remove transition 29 using the following ranking functions, which are bounded by 0.

l21: 0
l22: −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 2/4

Here we consider the SCC { l11, l12 }.

2.2.1 Transition Removal

We remove transition 14 using the following ranking functions, which are bounded by 0.

l12: −2⋅x1 + 2⋅x5 + 1
l11: −2⋅x1 + 2⋅x5

2.2.2 Transition Removal

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

l12: 0
l11: −1

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 { l25, l24 }.

2.3.1 Transition Removal

We remove transition 73 using the following ranking functions, which are bounded by 0.

l24: −1 − x2 + x6
l25: −1 − x2 + x6

2.3.2 Transition Removal

We remove transition 34 using the following ranking functions, which are bounded by 0.

l24: 0
l25: −1

2.3.3 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 { l31, l30 }.

2.4.1 Transition Removal

We remove transition 52 using the following ranking functions, which are bounded by 0.

l30: −1 − x3 + x7
l31: −1 − x3 + x7

2.4.2 Transition Removal

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

l30: 0
l31: −1

2.4.3 Trivial Cooperation Program

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