Termination proof succeeded
Initially, performed program simplifications using lexicographic rank functions:
 * Removed transitions 1, 4, 5 using the following rank functions:
    - Rank function 1:
      RF for loc. 5: 1-2*arg1
      RF for loc. 6: -2*arg1
      Bound for (chained) transitions 5: -18
    - Rank function 2:
      RF for loc. 5: -arg1
      RF for loc. 6: -arg1
      Bound for (chained) transitions 4: -19
    - Rank function 3:
      RF for loc. 5: 0
      RF for loc. 6: -1
      Bound for (chained) transitions 1: 0
