* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          double(x) -> g(d(),x)
          f(s(x),y) -> f(half(s(x)),double(y))
          f(s(0()),y) -> y
          g(x,0()) -> 0()
          g(d(),s(x)) -> s(s(g(d(),x)))
          g(h(),s(0())) -> 0()
          g(h(),s(s(x))) -> s(g(h(),x))
          half(x) -> g(h(),x)
          id(x) -> f(x,s(0()))
      - Signature:
          {double/1,f/2,g/2,half/1,id/1} / {0/0,d/0,h/0,s/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {double,f,g,half,id} and constructors {0,d,h,s}
