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 { l4, l6, l8 }.

2.1.1 Transition Removal

We remove transition 8 using the following ranking functions, which are bounded by 0.

l4:	−2 + x7
l6:	−1 + x7
l8:	−1 + x7

2.1.2 Transition Removal

We remove transitions 6, 11 using the following ranking functions, which are bounded by −1.

l4:	0
l6:	−1
l8:	−2

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 { l1, l0 }.

2.2.1 Transition Removal

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

l0:	−1 + x9
l1:	x9

2.2.2 Transition Removal

We remove transition 1 using the following ranking functions, which are bounded by 0.

l0:	0
l1:	−1

2.2.3 Trivial Cooperation Program

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