MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          h(f(x,y)) -> f(f(a(),h(h(y))),x)
      - Signature:
          {h/1} / {a/0,f/2}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {h} and constructors {a,f}
  + Applied Processor:
      NaturalPI {shape = Mixed 3, restrict = NoRestrict, uargs = UArgs, urules = URules, selector = Nothing}
  + Details:
      Incompatible
