MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          f(h(x)) -> f(i(x))
          f(i(x)) -> a()
          i(x) -> h(x)
      - Signature:
          {f/1,i/1} / {a/0,h/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {f,i} and constructors {a,h}
  + Applied Processor:
      NaturalPI {shape = Mixed 3, restrict = NoRestrict, uargs = UArgs, urules = URules, selector = Nothing}
