Query: perm(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: perm_in_2: (b,f) delete_in_3: (f,b,f) Transforming Prolog into the following Term Rewriting System: Pi-finite rewrite system: The TRS R consists of the following rules: perm_in_ga([], []) -> perm_out_ga([], []) perm_in_ga(.(X, Y), .(U, V)) -> U1_ga(X, Y, U, V, delete_in_aga(U, .(X, Y), W)) delete_in_aga(X, .(X, Y), Y) -> delete_out_aga(X, .(X, Y), Y) delete_in_aga(U, .(X, Y), .(X, Z)) -> U3_aga(U, X, Y, Z, delete_in_aga(U, Y, Z)) U3_aga(U, X, Y, Z, delete_out_aga(U, Y, Z)) -> delete_out_aga(U, .(X, Y), .(X, Z)) U1_ga(X, Y, U, V, delete_out_aga(U, .(X, Y), W)) -> U2_ga(X, Y, U, V, perm_in_ga(W, V)) U2_ga(X, Y, U, V, perm_out_ga(W, V)) -> perm_out_ga(.(X, Y), .(U, V)) The argument filtering Pi contains the following mapping: perm_in_ga(x1, x2) = perm_in_ga(x1) [] = [] perm_out_ga(x1, x2) = perm_out_ga(x2) .(x1, x2) = .(x1, x2) U1_ga(x1, x2, x3, x4, x5) = U1_ga(x5) delete_in_aga(x1, x2, x3) = delete_in_aga(x2) delete_out_aga(x1, x2, x3) = delete_out_aga(x1, x3) U3_aga(x1, x2, x3, x4, x5) = U3_aga(x2, x5) U2_ga(x1, x2, x3, x4, x5) = U2_ga(x3, x5) Infinitary Constructor Rewriting Termination of PiTRS implies Termination of Prolog ---------------------------------------- popout
