YES Termination w.r.t. Q proof of SK90_2.56.ari

(0) Obligation:

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

f(a, x) → g(a, x)
g(a, x) → f(b, x)
f(a, x) → f(b, x)

Q is empty.

(1) QTRSRRRProof (EQUIVALENT transformation)

Used ordering:
Knuth-Bendix order [KBO] with precedence:
g2 > f2 > b > a

and weight map:

a=2
b=1
f_2=1
g_2=0

The variable weight is 1With this ordering the following rules can be removed by the rule removal processor [LPAR04] because they are oriented strictly:

f(a, x) → g(a, x)
g(a, x) → f(b, x)
f(a, x) → f(b, x)


(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.

(4) YES
