**Lemma 1:** DATE's bounds are $[0, n]$ **Lemma 1:** Suppose we have $n$ processes, then $\not \exists p_{j} : DATE[j]=DATE[i] \forall i \in [0, n]$
**Lemma 2:** DATE's bounds are $[0, n]$
*Proof:* *Proof:*
For the upper bound, it's trivial: DATE is either decreased or set to $n$. For the upper bound, it's trivial: DATE is either decreased or set to $n$.
