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