The rewrite relation of the following TRS is considered.

f(a,h(b)) |

f(h(f(f(a,a),h(a))),g(f(x,g(b)))) |

f(y,x) |
Proof
1 Redundant Rules Transformation
To prove that the TRS is (non-)confluent, we show (non-)confluence of the following
modified system:
|
f(x,y) |
→ |
f(y,x) |
|
g(g(a)) |
→ |
f(h(g(f(c,c))),f(f(g(c),a),g(f(a,a)))) |
|
f(h(f(f(a,a),h(a))),g(f(x,g(b)))) |
→ |
c |
| c |
→ |
f(a,h(b)) |
All redundant rules that were added or removed can be
simulated in 1 steps
