1 Dependency Pair Transformation
The following set of initial dependency pairs has been identified.
b#(x1) |
→ |
a#(x1) |
(4) |
a#(a(b(a(x1)))) |
→ |
b#(b(a(a(a(x1))))) |
(5) |
a#(a(b(a(x1)))) |
→ |
b#(a(a(a(x1)))) |
(6) |
a#(a(b(a(x1)))) |
→ |
a#(a(x1)) |
(7) |
a#(a(b(a(x1)))) |
→ |
a#(a(a(x1))) |
