1 Switch to Cooperation Termination Proof

We consider the following cutpoint-transitions:

We consider subproblems for each of the 2 SCC(s) of the program graph.

7.1 SCC Subproblem 1/2

Here we consider the SCC { 0, 2, 3, 2_var_snapshot, 2* }.

7.1.1 Transition Removal

We remove transition 2 using the following ranking functions, which are bounded by 7.
