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