We consider the following cutpoint-transitions:

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

We consider subproblems for each of the 3 SCC(s) of the program graph.

Here we consider the SCC { f658_0_createIntList_LE }.

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

f658_0_createIntList_LE:

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

Here we consider the SCC { f698_0_nth_LE }.

We remove transition 5 using the following ranking functions, which are bounded by 0.

f698_0_nth_LE:

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

Here we consider the SCC { f746_0_main_LE }.

We remove transition 6 using the following ranking functions, which are bounded by 0.

f746_0_main_LE:

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