With regard to the inferred argument filtering the predicates were used in the following modes: 4.86/2.07 4.86/2.07 log_in_2: (b,f) 4.86/2.07 4.86/2.07 half_in_2: (b,f) 4.86/2.07 4.86/2.07 Transforming Prolog into the following Term Rewriting System: 4.86/2.07 4.86/2.07 Pi-finite rewrite system: 4.86/2.07 The TRS R consists of the following rules: 4.86/2.07 4.86/2.07 log_in_ga(0, s(0)) -> log_out_ga(0, s(0)) 4.86/2.07 log_in_ga(s(X), s(Y)) -> U2_ga(X, Y, half_in_ga(s(X), Z)) 4.86/2.07 half_in_ga(0, 0) -> half_out_ga(0, 0) 4.86/2.07 half_in_ga(s(0), 0) -> half_out_ga(s(0), 0) 4.86/2.07 half_in_ga(s(s(X)), s(Y)) -> U1_ga(X, Y, half_in_ga(X, Y)) 4.86/2.07 U1_ga(X, Y, half_out_ga(X, Y)) -> half_out_ga(s(s(X)), s(Y)) 4.86/2.07 U2_ga(X, Y, half_out_ga(s(X), Z)) -> U3_ga(X, Y, log_in_ga(Z, Y)) 4.86/2.07 U3_ga(X, Y, log_out_ga(Z, Y)) -> log_out_ga(s(X), s(Y)) 4.86/2.07 4.86/2.07 The argument filtering Pi contains the following mapping: 4.86/2.07 log_in_ga(x1, x2) = log_in_ga(x1) 4.86/2.07 4.86/2.07 0 = 0 4.86/2.07 4.86/2.07 log_out_ga(x1, x2) = log_out_ga(x2) 4.86/2.07 4.86/2.07 s(x1) = s(x1) 4.86/2.07 4.86/2.07 U2_ga(x1, x2, x3) = U2_ga(x3) 4.86/2.07 4.86/2.07 half_in_ga(x1, x2) = half_in_ga(x1) 4.86/2.07 4.86/2.07 half_out_ga(x1, x2) = half_out_ga(x2) 4.86/2.07 4.86/2.07 U1_ga(x1, x2, x3) = U1_ga(x3) 4.86/2.07 4.86/2.07 U3_ga(x1, x2, x3) = U3_ga(x3) 4.86/2.07 4.86/2.07 4.86/2.07 4.86/2.07 4.86/2.07 4.86/2.07 Infinitary Constructor Rewriting Termination of PiTRS implies Termination of Prolog 4.86/2.07 4.86/2.07 4.86/2.07 popout
