MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          f(f(x)) -> b()
          f(g(a())) -> a()
          g(x) -> f(g(x))
      - Signature:
          {f/1,g/1} / {a/0,b/0}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {f,g} and constructors {a,b}
