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