LTS Termination Proof

by AProVE

Input

• Initial Location: f1_0_main_New, f200_0_solve_GE, __init
• Transitions: (pre-variables and post-variables)

  f1_0_main_New	1	f200_0_solve_GE:		x1 = _arg1 ∧ x1 = _arg1P ∧ 5 = _arg1P
  f200_0_solve_GE	2	f200_0_solve_GE:		x1 = _x ∧ x1 = _x1 ∧ _x − 1 = _x1 ∧ _x − 1 ≤ _x − 1 ∧ 1 ≤ _x − 1
  __init	3	f1_0_main_New:		x1 = _x2 ∧ x1 = _x3 ∧ 0 ≤ 0

Proof

1 Switch to Cooperation Termination Proof

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 { f200_0_solve_GE }.

2.1.1 Transition Removal

We remove transition 2 using the following ranking functions, which are bounded by 0.

2.1.2 Trivial Cooperation Program

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