The TRS R consists of the following rules: a__fst(0, Z) -> nil a__fst(s(X), cons(Y, Z)) -> cons(mark(Y), fst(X, Z)) a__from(X) -> cons(mark(X), from(s(X))) a__add(0, X) -> mark(X) a__add(s(X), Y) -> s(add(X, Y)) a__len(nil) -> 0 a__len(cons(X, Z)) -> s(len(Z)) mark(fst(X1, X2)) -> a__fst(mark(X1), mark(X2)) mark(from(X)) -> a__from(mark(X)) mark(add(X1, X2)) -> a__add(mark(X1), mark(X2)) mark(len(X)) -> a__len(mark(X)) mark(0) -> 0 mark(s(X)) -> s(X) mark(nil) -> nil mark(cons(X1, X2)) -> cons(mark(X1), X2) a__fst(X1, X2) -> fst(X1, X2) a__from(X) -> from(X) a__add(X1, X2) -> add(X1, X2) a__len(X) -> len(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(0) -> 0 encArg(nil) -> nil encArg(s(x_1)) -> s(encArg(x_1)) encArg(cons(x_1, x_2)) -> cons(encArg(x_1), encArg(x_2)) encArg(fst(x_1, x_2)) -> fst(encArg(x_1), encArg(x_2)) encArg(from(x_1)) -> from(encArg(x_1)) encArg(add(x_1, x_2)) -> add(encArg(x_1), encArg(x_2)) encArg(len(x_1)) -> len(encArg(x_1)) encArg(cons_a__fst(x_1, x_2)) -> a__fst(encArg(x_1), encArg(x_2)) encArg(cons_a__from(x_1)) -> a__from(encArg(x_1)) encArg(cons_a__add(x_1, x_2)) -> a__add(encArg(x_1), encArg(x_2)) encArg(cons_a__len(x_1)) -> a__len(encArg(x_1)) encArg(cons_mark(x_1)) -> mark(encArg(x_1)) encode_a__fst(x_1, x_2) -> a__fst(encArg(x_1), encArg(x_2)) encode_0 -> 0 encode_nil -> nil encode_s(x_1) -> s(encArg(x_1)) encode_cons(x_1, x_2) -> cons(encArg(x_1), encArg(x_2)) encode_mark(x_1) -> mark(encArg(x_1)) encode_fst(x_1, x_2) -> fst(encArg(x_1), encArg(x_2)) encode_a__from(x_1) -> a__from(encArg(x_1)) encode_from(x_1) -> from(encArg(x_1)) encode_a__add(x_1, x_2) -> a__add(encArg(x_1), encArg(x_2)) encode_add(x_1, x_2) -> add(encArg(x_1), encArg(x_2)) encode_a__len(x_1) -> a__len(encArg(x_1)) encode_len(x_1) -> len(encArg(x_1)) ---------------------------------------- (2) Obligation: The Runtime Complexity (innermost) of the given CpxRelTRS could be proven to be BOUNDS(n^1, INF).
