We consider subproblems for each of the 1 SCC(s) of the program graph.
Here we consider the SCC {
, , , , }.We remove transitions
, using the following ranking functions, which are bounded by 0.: | −1 − x3 + x4 |
: | −1 − x3 + x4 |
: | −1 − x3 + x4 |

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