Query: reach(g,g,g,g) ---------------------------------------- (1) PrologToPiTRSProof (SOUND) We use the technique of [TOCL09]. With regard to the inferred argument filtering the predicates were used in the following modes: reach_in_4: (b,b,b,b) member_in_2: (b,b) member1_in_2: (f,b) delete_in_3: (b,b,f) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system: The TRS R consists of the following rules: reach_in_gggg(X, Y, E, L) -> U1_gggg(X, Y, E, L, member_in_gg(.(X, .(Y, [])), E)) member_in_gg(H, .(H, L)) -> member_out_gg(H, .(H, L)) member_in_gg(X, .(H, L)) -> U6_gg(X, H, L, member_in_gg(X, L)) U6_gg(X, H, L, member_out_gg(X, L)) -> member_out_gg(X, .(H, L)) U1_gggg(X, Y, E, L, member_out_gg(.(X, .(Y, [])), E)) -> reach_out_gggg(X, Y, E, L) reach_in_gggg(X, Z, E, L) -> U2_gggg(X, Z, E, L, member1_in_ag(.(X, .(Y, [])), E)) member1_in_ag(H, .(H, L)) -> member1_out_ag(H, .(H, L)) member1_in_ag(X, .(H, L)) -> U7_ag(X, H, L, member1_in_ag(X, L)) U7_ag(X, H, L, member1_out_ag(X, L)) -> member1_out_ag(X, .(H, L))
