MAYBE
* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          f(x,x) -> f(i(x),g(g(x)))
          f(x,y) -> x
          f(x,i(x)) -> f(x,x)
          f(i(x),i(g(x))) -> a()
          g(x) -> i(x)
      - Signature:
          {f/2,g/1} / {a/0,i/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {f,g} and constructors {a,i}
