Query: f(g,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: f_in_3: (b,b,f) g_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: f_in_gga(A, [], RES) -> U1_gga(A, RES, g_in_gga(A, [], RES)) g_in_gga([], RES, RES) -> g_out_gga([], RES, RES) g_in_gga(.(C, Cs), D, RES) -> U3_gga(C, Cs, D, RES, g_in_gga(Cs, .(C, D), RES)) U3_gga(C, Cs, D, RES, g_out_gga(Cs, .(C, D), RES)) -> g_out_gga(.(C, Cs), D, RES) U1_gga(A, RES, g_out_gga(A, [], RES)) -> f_out_gga(A, [], RES) f_in_gga(.(A, As), .(B, Bs), RES) -> U2_gga(A, As, B, Bs, RES, f_in_gga(.(B, .(A, As)), Bs, RES)) U2_gga(A, As, B, Bs, RES, f_out_gga(.(B, .(A, As)), Bs, RES)) -> f_out_gga(.(A, As), .(B, Bs), RES) The argument filtering Pi contains the following mapping: f_in_gga(x1, x2, x3) = f_in_gga(x1, x2) [] = [] U1_gga(x1, x2, x3) = U1_gga(x1, x3) g_in_gga(x1, x2, x3) = g_in_gga(x1, x2) g_out_gga(x1, x2, x3) = g_out_gga(x1, x2, x3) .(x1, x2) = .(x1, x2) U3_gga(x1, x2, x3, x4, x5) = U3_gga(x1, x2, x3, x5) f_out_gga(x1, x2, x3) = f_out_gga(x1, x2, x3) U2_gga(x1, x2, x3, x4, x5, x6) = U2_gga(x1, x2, x3, x4, x6) Infinitary Constructor Rewriting Termination of PiTRS implies Termination of Prolog
