Q restricted rewrite system:
The TRS R consists of the following rules:

f(g(f(a), h(a, f(a)))) → f(h(g(f(a), a), g(f(a), f(a))))

Q is empty.

(1) QTRSRRRProof (EQUIVALENT transformation)

Used ordering:
Lexicographic Path Order [LPO].
Precedence:
[f1, g2, a] > h2

With this ordering the following rules can be removed by the rule removal processor [LPAR04] because they are oriented strictly:

f(g(f(a), h(a, f(a)))) → f(h(g(f(a), a), g(f(a), f(a))))


(2) Obligation:

Q restricted rewrite system:
R is empty.
Q is empty.

(3) RisEmptyProof (EQUIVALENT transformation)

The TRS R is empty. Hence, termination is trivially proven.
