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