We consider subproblems for each of the 1 SCC(s) of the program graph.
Here we consider the SCC { , }.
We remove transition using the following ranking functions, which are bounded by 0.
| : | −2⋅x3 + 2⋅x1 | 
| : | 2⋅x1 − 2⋅x3 − 1 | 
We remove transition using the following ranking functions, which are bounded by 0.
| : | 0 | 
| : | −1 | 
There are no more "sharp" transitions in the cooperation program. Hence the cooperation termination is proved.
