Termination Proof Script
Consider the TRS R consisting of the rewrite rules
|
| 1: |
|
f(x,x) |
→ a |
| 2: |
|
f(g(x),y) |
→ f(x,y) |
|
There is one dependency pair:
The approximated dependency graph contains one SCC:
{3}.
-
Consider the SCC {3}.
There are no usable rules.
By taking the AF π with
π(F) = 1 together with
the lexicographic path order with
empty precedence,
rule 3
is strictly decreasing.
Hence the TRS is terminating.
