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