Obligation:
Clauses:

p(X, Y, Z) :- append(.(X, Y), Z, Y).
append([], Y, Y).

(1) PrologToPiTRSProof (SOUND)
We use the technique of [TOCL09]. With regard to the inferred argument filtering the predicates were used in the following modes:

p_in_3: (f,f,f)

append_in_3: (f,f,f)

Transforming Prolog into the following Term Rewriting System:

Pi-finite rewrite system:
The TRS R consists of the following rules:

popout

output may be truncated. 'popout' for the full output.

job log
