The TRS R consists of the following rules: c(z, x, a) -> f(b(b(f(z), z), x)) b(y, b(z, a)) -> f(b(c(f(a), y, z), z)) f(c(c(z, a, a), x, a)) -> z 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(a) -> a encArg(cons_c(x_1, x_2, x_3)) -> c(encArg(x_1), encArg(x_2), encArg(x_3)) encArg(cons_b(x_1, x_2)) -> b(encArg(x_1), encArg(x_2)) encArg(cons_f(x_1)) -> f(encArg(x_1)) encode_c(x_1, x_2, x_3) -> c(encArg(x_1), encArg(x_2), encArg(x_3)) encode_a -> a encode_f(x_1) -> f(encArg(x_1)) encode_b(x_1, x_2) -> b(encArg(x_1), encArg(x_2)) ---------------------------------------- (2) Obligation: The Runtime Complexity (innermost) of the given CpxRelTRS could be proven to be BOUNDS(1, n^2). The TRS R consists of the following rules: c(z, x, a) -> f(b(b(f(z), z), x)) b(y, b(z, a)) -> f(b(c(f(a), y, z), z)) f(c(c(z, a, a), x, a)) -> z The (relative) TRS S consists of the following rules: encArg(a) -> a encArg(cons_c(x_1, x_2, x_3)) -> c(encArg(x_1), encArg(x_2), encArg(x_3)) encArg(cons_b(x_1, x_2)) -> b(encArg(x_1), encArg(x_2)) encArg(cons_f(x_1)) -> f(encArg(x_1)) encode_c(x_1, x_2, x_3) -> c(encArg(x_1), encArg(x_2), encArg(x_3)) encode_a -> a encode_f(x_1) -> f(encArg(x_1)) encode_b(x_1, x_2) -> b(encArg(x_1), encArg(x_2)) Rewrite Strategy: INNERMOST ---------------------------------------- (3) SInnermostTerminationProof (BOTH CONCRETE BOUNDS(ID, ID)) proved innermost termination of relative rules ---------------------------------------- (4) Obligation: The Runtime Complexity (innermost) of the given CpxRelTRS could be proven to be BOUNDS(1, n^2).
