※ 引述《huskybaby (哈士奇)》之銘言：
: 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
如果在一個存在最佳解的線性方程組中,
其方程式是多於所求變數,則表示存在多餘的限制式.
: (2)the system BX=b has infinity of solutions if B is singular, and b is dependent relative to the vectors of B.
: 這兩題不太懂在問什麼，有人會解這兩小題嗎？
