Q restricted rewrite system:
The TRS R consists of the following rules:
app(id, x) → x
app(plus, 0) → id
app(app(plus, app(s, x)), y) → app(s, app(app(plus, x), y))
Q is empty.
(1) QTRSRRRProof (EQUIVALENT transformation)
Used ordering:
Polynomial interpretation [POLO]:
POL(0) = 1
POL(app(x1, x2)) = 1 + 2·x1 + x2
POL(id) = 1
POL(plus) = 1
POL(s) = 2
With this ordering the following rules can be removed by the rule removal processor [LPAR04] because they are oriented strictly:
app(id, x) → x
app(plus, 0) → id
app(app(plus, app(s, x)), y) → app(s, app(app(plus, x), y))
(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.
