Termination Proof Script
Consider the TRS R consisting of the rewrite rules
|
| 1: |
|
g(0,f(x,x)) |
→ x |
| 2: |
|
g(x,s(y)) |
→ g(f(x,y),0) |
| 3: |
|
g(s(x),y) |
→ g(f(x,y),0) |
| 4: |
|
g(f(x,y),0) |
→ f(g(x,0),g(y,0)) |
|
There are 4 dependency pairs:
|
| 5: |
|
G(x,s(y)) |
→ G(f(x,y),0) |
| 6: |
|
G(s(x),y) |
→ G(f(x,y),0) |
| 7: |
|
G(f(x,y),0) |
→ G(x,0) |
| 8: |
|
G(f(x,y),0) |
→ G(y,0) |
|
The approximated dependency graph contains one SCC:
{6-8}.
-
Consider the SCC {6-8}.
There are no usable rules.
The constraints could not be solved.
