Query: samefringe(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: samefringe_in_2: (b,b) gopher_in_2: (b,f) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system: The TRS R consists of the following rules: samefringe_in_gg(nil, nil) -> samefringe_out_gg(nil, nil) samefringe_in_gg(cons(U, V), cons(X, Y)) -> U2_gg(U, V, X, Y, gopher_in_ga(cons(U, V), cons(U1, V1))) gopher_in_ga(nil, nil) -> gopher_out_ga(nil, nil) gopher_in_ga(cons(nil, Y), cons(nil, Y)) -> gopher_out_ga(cons(nil, Y), cons(nil, Y)) gopher_in_ga(cons(cons(U, V), W), X) -> U1_ga(U, V, W, X, gopher_in_ga(cons(U, cons(V, W)), X)) U1_ga(U, V, W, X, gopher_out_ga(cons(U, cons(V, W)), X)) -> gopher_out_ga(cons(cons(U, V), W), X) U2_gg(U, V, X, Y, gopher_out_ga(cons(U, V), cons(U1, V1))) -> U3_gg(U, V, X, Y, U1, V1, gopher_in_ga(cons(X, Y), cons(X1, Y1))) U3_gg(U, V, X, Y, U1, V1, gopher_out_ga(cons(X, Y), cons(X1, Y1))) -> U4_gg(U, V, X, Y, samefringe_in_gg(V1, Y1)) U4_gg(U, V, X, Y, samefringe_out_gg(V1, Y1)) -> samefringe_out_gg(cons(U, V), cons(X, Y)) The argument filtering Pi contains the following mapping: samefringe_in_gg(x1, x2) = samefringe_in_gg(x1, x2) nil = nil samefringe_out_gg(x1, x2) = samefringe_out_gg cons(x1, x2) = cons(x1, x2) U2_gg(x1, x2, x3, x4, x5) = U2_gg(x3, x4, x5) gopher_in_ga(x1, x2) = gopher_in_ga(x1) gopher_out_ga(x1, x2) = gopher_out_ga(x2) U1_ga(x1, x2, x3, x4, x5) = U1_ga(x5) U3_gg(x1, x2, x3, x4, x5, x6, x7) = U3_gg(x6, x7) U4_gg(x1, x2, x3, x4, x5) = U4_gg(x5) popout
