Query: qs(g,a) ---------------------------------------- (1) PrologToPiTRSProof (SOUND) We use the technique of [TOCL09]. With regard to the inferred argument filtering the predicates were used in the following modes: qs_in_2: (b,f) split_in_4: (b,b,f,f) less_in_2: (b,b) geq_in_2: (b,b) append_in_3: (b,b,f) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system:
