(0)
Obligation:
The Runtime Complexity (innermost) of the given CpxTRS could be proven to be BOUNDS(n^1, n^1).


The TRS R consists of the following rules:

   lt(0, s(x)) -> true
   lt(x, 0) -> false
   lt(s(x), s(y)) -> lt(x, y)
   logarithm(x) -> ifa(lt(0, x), x)
   ifa(true, x) -> help(x, 1)
   ifa(false, x) -> logZeroError
   help(x, y) -> ifb(lt(y, x), x, y)
   ifb(true, x, y) -> help(half(x), s(y))
   ifb(false, x, y) -> y
   half(0) -> 0
   half(s(0)) -> 0
   half(s(s(x))) -> s(half(x))

S is empty.

(2)
Obligation:
The Runtime Complexity (innermost) of the given CpxWeightedTrs could be proven to be BOUNDS(1, n^1).


The TRS R consists of the following rules:

   lt(0, s(x)) -> true [1]
   lt(x, 0) -> false [1]
   lt(s(x), s(y)) -> lt(x, y) [1]
   logarithm(x) -> ifa(lt(0, x), x) [1]
   ifa(true, x) -> help(x, 1) [1]
   ifa(false, x) -> logZeroError [1]
   help(x, y) -> ifb(lt(y, x), x, y) [1]
   ifb(true, x, y) -> help(half(x), s(y)) [1]
   ifb(false, x, y) -> y [1]
   half(0) -> 0 [1]
   half(s(0)) -> 0 [1]
   half(s(s(x))) -> s(half(x)) [1]
