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