* Step 1: Failure MAYBE
  + Considered Problem:
      - Strict TRS:
          f(k(a()),k(b()),X) -> f(X,X,X)
          g(X) -> u(h(X),h(X),X)
          h(d()) -> c(a())
          h(d()) -> c(b())
          u(d(),c(Y),X) -> k(Y)
      - Signature:
          {f/3,g/1,h/1,u/3} / {a/0,b/0,c/1,d/0,k/1}
      - Obligation:
          innermost runtime complexity wrt. defined symbols {f,g,h,u} and constructors {a,b,c,d,k}
