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