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.: | x2 |
We remove transition
using the following ranking functions, which are bounded by 0.: | x1 |
There are no more "sharp" transitions in the cooperation program. Hence the cooperation termination is proved.
