The optimal "splitting point" for a fixed i increases as j increases. This lets us solve for all states more efficiently. Say we compute o p t ( i, j) for some fixed i and j . Then for any j ′ < j we know that o p t ( i, j ′) ≤ o p t ( i, j) . This means when computing o p t ( i, j ′) , we don't ...
