MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          b(X) -> a(X)
          f(a(g(X))) -> b(X)
          f(f(X)) -> f(a(b(f(X))))
      - Signature:
          {b/1,f/1} / {a/1,g/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {b,f} and constructors {a,g}
