The TRS R consists of the following rules: a__from(X) -> cons(mark(X), from(s(X))) a__2ndspos(0, Z) -> rnil a__2ndspos(s(N), cons(X, Z)) -> a__2ndspos(s(mark(N)), cons2(X, mark(Z))) a__2ndspos(s(N), cons2(X, cons(Y, Z))) -> rcons(posrecip(mark(Y)), a__2ndsneg(mark(N), mark(Z))) a__2ndsneg(0, Z) -> rnil a__2ndsneg(s(N), cons(X, Z)) -> a__2ndsneg(s(mark(N)), cons2(X, mark(Z))) a__2ndsneg(s(N), cons2(X, cons(Y, Z))) -> rcons(negrecip(mark(Y)), a__2ndspos(mark(N), mark(Z))) a__pi(X) -> a__2ndspos(mark(X), a__from(0)) a__plus(0, Y) -> mark(Y) a__plus(s(X), Y) -> s(a__plus(mark(X), mark(Y))) a__times(0, Y) -> 0 a__times(s(X), Y) -> a__plus(mark(Y), a__times(mark(X), mark(Y))) a__square(X) -> a__times(mark(X), mark(X)) mark(from(X)) -> a__from(mark(X)) mark(2ndspos(X1, X2)) -> a__2ndspos(mark(X1), mark(X2)) mark(2ndsneg(X1, X2)) -> a__2ndsneg(mark(X1), mark(X2)) mark(pi(X)) -> a__pi(mark(X)) mark(plus(X1, X2)) -> a__plus(mark(X1), mark(X2)) mark(times(X1, X2)) -> a__times(mark(X1), mark(X2)) mark(square(X)) -> a__square(mark(X)) mark(0) -> 0 mark(s(X)) -> s(mark(X)) mark(posrecip(X)) -> posrecip(mark(X)) mark(negrecip(X)) -> negrecip(mark(X)) mark(nil) -> nil mark(cons(X1, X2)) -> cons(mark(X1), X2) mark(cons2(X1, X2)) -> cons2(X1, mark(X2)) mark(rnil) -> rnil mark(rcons(X1, X2)) -> rcons(mark(X1), mark(X2)) a__from(X) -> from(X) a__2ndspos(X1, X2) -> 2ndspos(X1, X2) a__2ndsneg(X1, X2) -> 2ndsneg(X1, X2) a__pi(X) -> pi(X) a__plus(X1, X2) -> plus(X1, X2) a__times(X1, X2) -> times(X1, X2) a__square(X) -> square(X) S is empty. Rewrite Strategy: INNERMOST ---------------------------------------- (1) DerivationalComplexityToRuntimeComplexityProof (BOTH BOUNDS(ID, ID)) The following rules have been added to S to convert the given derivational complexity problem to a runtime complexity problem: encArg(cons(x_1, x_2)) -> cons(encArg(x_1), encArg(x_2)) encArg(from(x_1)) -> from(encArg(x_1)) encArg(s(x_1)) -> s(encArg(x_1)) encArg(0) -> 0 encArg(rnil) -> rnil encArg(cons2(x_1, x_2)) -> cons2(encArg(x_1), encArg(x_2)) encArg(rcons(x_1, x_2)) -> rcons(encArg(x_1), encArg(x_2)) encArg(posrecip(x_1)) -> posrecip(encArg(x_1)) encArg(negrecip(x_1)) -> negrecip(encArg(x_1)) encArg(2ndspos(x_1, x_2)) -> 2ndspos(encArg(x_1), encArg(x_2)) encArg(2ndsneg(x_1, x_2)) -> 2ndsneg(encArg(x_1), encArg(x_2)) encArg(pi(x_1)) -> pi(encArg(x_1)) encArg(plus(x_1, x_2)) -> plus(encArg(x_1), encArg(x_2)) encArg(times(x_1, x_2)) -> times(encArg(x_1), encArg(x_2)) encArg(square(x_1)) -> square(encArg(x_1)) encArg(nil) -> nil encArg(cons_a__from(x_1)) -> a__from(encArg(x_1)) encArg(cons_a__2ndspos(x_1, x_2)) -> a__2ndspos(encArg(x_1), encArg(x_2)) encArg(cons_a__2ndsneg(x_1, x_2)) -> a__2ndsneg(encArg(x_1), encArg(x_2)) encArg(cons_a__pi(x_1)) -> a__pi(encArg(x_1)) encArg(cons_a__plus(x_1, x_2)) -> a__plus(encArg(x_1), encArg(x_2)) encArg(cons_a__times(x_1, x_2)) -> a__times(encArg(x_1), encArg(x_2)) encArg(cons_a__square(x_1)) -> a__square(encArg(x_1)) encArg(cons_mark(x_1)) -> mark(encArg(x_1)) encode_a__from(x_1) -> a__from(encArg(x_1))
