Proof

1 Switch to Cooperation Termination Proof

We consider the following cutpoint-transitions:
f852_0_loop_LT f852_0_loop_LT f852_0_loop_LT: x1 = x1x2 = x2x3 = x3x4 = x4x5 = x5x6 = x6x7 = x7
f1_0_main_Load f1_0_main_Load f1_0_main_Load: x1 = x1x2 = x2x3 = x3x4 = x4x5 = x5x6 = x6x7 = x7
__init __init __init: x1 = x1x2 = x2x3 = x3x4 = x4x5 = x5x6 = x6x7 = x7
and for every transition t, a duplicate t is considered.

2 SCC Decomposition

We consider subproblems for each of the 1 SCC(s) of the program graph.

2.1 SCC Subproblem 1/1

Here we consider the SCC { f852_0_loop_LT }.

2.1.1 Transition Removal

We remove transitions 6, 7 using the following ranking functions, which are bounded by 0.

f852_0_loop_LT: −1 + x6x7

2.1.2 Transition Removal

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

f852_0_loop_LT: x2

2.1.3 Trivial Cooperation Program

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