Initially, performed program simplifications using lexicographic rank functions:
 * Removed transitions 32, 34, 35, 40, 41, 44, 45, 50 using the following rank functions:
    - Rank function 1:
      RF for loc. 15: -1+3*arg1
      RF for loc. 16: 3*arg4
      RF for loc. 25: 1+3*arg1
      RF for loc. 29: -2+3*arg1
      Bound for (chained) transitions 32, 40: 2
      Bound for (chained) transitions 34: 4
      Bound for (chained) transitions 35: 1
      Bound for (chained) transitions 44: -2
      Bound for (chained) transitions 45: -2
      Bound for (chained) transitions 50: 0
    - Rank function 2:
      RF for loc. 15: 1
      RF for loc. 29: 0
      Bound for (chained) transitions 41: 1
 * Removed transitions 14, 16, 17, 22, 23, 26, 27 using the following rank functions:
