The TRS R consists of the following rules: nthtail(n, l) -> cond(ge(n, length(l)), n, l) cond(true, n, l) -> l cond(false, n, l) -> tail(nthtail(s(n), l)) tail(nil) -> nil tail(cons(x, l)) -> l length(nil) -> 0 length(cons(x, l)) -> s(length(l)) ge(u, 0) -> true ge(0, s(v)) -> false ge(s(u), s(v)) -> ge(u, v) S is empty. Rewrite Strategy: INNERMOST ---------------------------------------- (1) RelTrsToWeightedTrsProof (BOTH BOUNDS(ID, ID)) Transformed relative TRS to weighted TRS ---------------------------------------- (2) Obligation: The Runtime Complexity (innermost) of the given CpxWeightedTrs could be proven to be BOUNDS(1, n^2). The TRS R consists of the following rules: nthtail(n, l) -> cond(ge(n, length(l)), n, l) [1] cond(true, n, l) -> l [1] cond(false, n, l) -> tail(nthtail(s(n), l)) [1] tail(nil) -> nil [1] tail(cons(x, l)) -> l [1] length(nil) -> 0 [1] length(cons(x, l)) -> s(length(l)) [1] ge(u, 0) -> true [1] ge(0, s(v)) -> false [1] ge(s(u), s(v)) -> ge(u, v) [1] Rewrite Strategy: INNERMOST ---------------------------------------- (3) TypeInferenceProof (BOTH BOUNDS(ID, ID)) Infered types. ---------------------------------------- (4) Obligation: Runtime Complexity Weighted TRS with Types. The TRS R consists of the following rules: nthtail(n, l) -> cond(ge(n, length(l)), n, l) [1] cond(true, n, l) -> l [1] cond(false, n, l) -> tail(nthtail(s(n), l)) [1] tail(nil) -> nil [1] tail(cons(x, l)) -> l [1] length(nil) -> 0 [1] length(cons(x, l)) -> s(length(l)) [1] ge(u, 0) -> true [1] ge(0, s(v)) -> false [1] ge(s(u), s(v)) -> ge(u, v) [1] The TRS has the following type information: nthtail :: s:0 -> nil:cons -> nil:cons cond :: true:false -> s:0 -> nil:cons -> nil:cons popout
