Find a valid inequality for



$$
{xin{0,1}^5 mid 9x_1 + 8x_2 + 6x_3 + 6x_4 + 5x_5 leq 14}
$$



that cuts off $(1/4, 1/8, 3/4, 3/4, 0)$.



I tried both Chvàtal cut and cover inequality, both of which don’t work.

          Of the $32$ vertices of the $5$-cube, $14$ satisfy your constraint.

          If $w = (1/4,1/8,3/4,3/4,0)$, try maximizing $y cdot w - c$ subject to
          $y cdot v le c$ for those vertices $v$, where say $-1 le y_i le 1$.
