Query: slowsort(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: slowsort_in_2: (b,f) perm_in_2: (b,f) delete_in_3: (f,b,f) sorted_in_1: (b) le_in_2: (b,b) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system: The TRS R consists of the following rules: slowsort_in_ga(X, Y) -> U1_ga(X, Y, perm_in_ga(X, Y)) perm_in_ga([], []) -> perm_out_ga([], [])
