### Bound for z(11,14)

By the scaffold algorithm, neither of the two candidate scaffolds has a solution of weight above 45.

Scaffold: $p=4$, $q=2$, $\mathbf{m}=(2,2,2,2)$, $\mathbf{n}=(4,3)$, $m_O=0$, $n_O=2$.

(0.021270581 seconds, score = 0, 99 recursive calls, max depth = 13)

Scaffold: $p=4$, $q=2$, $\mathbf{m}=(2,2,2,2)$, $\mathbf{n}=(3,3)$, $m_O=0$, $n_O=3$.

(3.61778E-4 seconds, score = 0, 0 recursive calls, max depth = 0)
