Q restricted rewrite system:
The TRS R consists of the following rules:

   half(0) -> 0
   half(s(0)) -> 0
   half(s(s(x))) -> s(half(x))
   le(0, y) -> true
   le(s(x), 0) -> false
   le(s(x), s(y)) -> le(x, y)
   inc(s(x)) -> s(inc(x))
   inc(0) -> s(0)
   logarithm(x) -> logIter(x, 0)
   logIter(x, y) -> if(le(s(0), x), le(s(s(0)), x), half(x), inc(y))
   if(false, b, x, y) -> logZeroError
