The TRS R consists of the following rules: a__p(0) -> 0 a__p(s(X)) -> mark(X) a__leq(0, Y) -> true a__leq(s(X), 0) -> false a__leq(s(X), s(Y)) -> a__leq(mark(X), mark(Y)) a__if(true, X, Y) -> mark(X) a__if(false, X, Y) -> mark(Y) a__diff(X, Y) -> a__if(a__leq(mark(X), mark(Y)), 0, s(diff(p(X), Y))) mark(p(X)) -> a__p(mark(X)) mark(leq(X1, X2)) -> a__leq(mark(X1), mark(X2)) mark(if(X1, X2, X3)) -> a__if(mark(X1), X2, X3) mark(diff(X1, X2)) -> a__diff(mark(X1), mark(X2)) mark(0) -> 0 mark(s(X)) -> s(mark(X)) mark(true) -> true mark(false) -> false a__p(X) -> p(X) a__leq(X1, X2) -> leq(X1, X2) a__if(X1, X2, X3) -> if(X1, X2, X3) a__diff(X1, X2) -> diff(X1, X2) 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(s(x_1)) -> s(encArg(x_1)) encArg(true) -> true encArg(false) -> false encArg(diff(x_1, x_2)) -> diff(encArg(x_1), encArg(x_2)) encArg(p(x_1)) -> p(encArg(x_1)) encArg(leq(x_1, x_2)) -> leq(encArg(x_1), encArg(x_2)) encArg(if(x_1, x_2, x_3)) -> if(encArg(x_1), encArg(x_2), encArg(x_3)) encArg(cons_a__p(x_1)) -> a__p(encArg(x_1)) encArg(cons_a__leq(x_1, x_2)) -> a__leq(encArg(x_1), encArg(x_2)) encArg(cons_a__if(x_1, x_2, x_3)) -> a__if(encArg(x_1), encArg(x_2), encArg(x_3)) encArg(cons_a__diff(x_1, x_2)) -> a__diff(encArg(x_1), encArg(x_2)) encArg(cons_mark(x_1)) -> mark(encArg(x_1)) encode_a__p(x_1) -> a__p(encArg(x_1)) encode_0 -> 0 encode_s(x_1) -> s(encArg(x_1)) encode_mark(x_1) -> mark(encArg(x_1)) encode_a__leq(x_1, x_2) -> a__leq(encArg(x_1), encArg(x_2)) encode_true -> true encode_false -> false encode_a__if(x_1, x_2, x_3) -> a__if(encArg(x_1), encArg(x_2), encArg(x_3)) encode_a__diff(x_1, x_2) -> a__diff(encArg(x_1), encArg(x_2)) encode_diff(x_1, x_2) -> diff(encArg(x_1), encArg(x_2)) encode_p(x_1) -> p(encArg(x_1)) encode_leq(x_1, x_2) -> leq(encArg(x_1), encArg(x_2)) encode_if(x_1, x_2, x_3) -> if(encArg(x_1), encArg(x_2), encArg(x_3))
