※ 引述《huskybaby (哈士奇)》之铭言：
: which of the following questions are TRUE or FALSE？Why？
: (1)When the optimal solution of a LP model is over determined,
:it means at least one of the constraints is redundant and vice versa.
Ans: T
如果在一个存在最佳解的线性方程组中,
其方程式是多於所求变数,则表示存在多余的限制式.
: (2)the system BX=b has infinity of solutions if B is singular, and b is dependent relative to the vectors of B.
: 这两题不太懂在问什麽，有人会解这两小题吗？
