The TRS R consists of the following rules: a__f(X) -> a__if(mark(X), c, f(true)) a__if(true, X, Y) -> mark(X) a__if(false, X, Y) -> mark(Y) mark(f(X)) -> a__f(mark(X)) mark(if(X1, X2, X3)) -> a__if(mark(X1), mark(X2), X3) mark(c) -> c mark(true) -> true mark(false) -> false a__f(X) -> f(X) a__if(X1, X2, X3) -> if(X1, X2, X3) 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(c) -> c encArg(f(x_1)) -> f(encArg(x_1)) encArg(true) -> true encArg(false) -> false encArg(if(x_1, x_2, x_3)) -> if(encArg(x_1), encArg(x_2), encArg(x_3)) encArg(cons_a__f(x_1)) -> a__f(encArg(x_1)) encArg(cons_a__if(x_1, x_2, x_3)) -> a__if(encArg(x_1), encArg(x_2), encArg(x_3)) encArg(cons_mark(x_1)) -> mark(encArg(x_1)) encode_a__f(x_1) -> a__f(encArg(x_1)) encode_a__if(x_1, x_2, x_3) -> a__if(encArg(x_1), encArg(x_2), encArg(x_3)) encode_mark(x_1) -> mark(encArg(x_1)) encode_c -> c encode_f(x_1) -> f(encArg(x_1)) encode_true -> true encode_false -> false encode_if(x_1, x_2, x_3) -> if(encArg(x_1), encArg(x_2), encArg(x_3)) ---------------------------------------- (2) Obligation: The Runtime Complexity (innermost) of the given CpxRelTRS could be proven to be BOUNDS(n^1, INF).
