and for every transition t, a duplicate t is considered.

2 SCC Decomposition

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

2.1 SCC Subproblem 1/2

Here we consider the SCC { l18, l30 }.

2.1.1 Transition Removal

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

l18: −1 − x22 + x23
l30: −1 − x22 + x23

2.1.2 Transition Removal

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

l30: 0
l18: −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 2/2

Here we consider the SCC { l23, l22, l24, l1, l20, l19, l21 }.

2.2.1 Transition Removal

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

l1: x15
l20: −1 + x15
l19: x15
l24: x16
l23: x16
l22: x16
l21: −1 + x15

2.2.2 Transition Removal

We remove transitions 25, 24, 23, 22, 21, 20 using the following ranking functions, which are bounded by 0.

l19: 0
l1: −1
l24: 1
l23: 2
l22: 3
l21: 4
l20: 5

2.2.3 Trivial Cooperation Program

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