Hello!

My questions are: find dual of a) min z^t*x, Ax=b.. l <= x <= d

b) min z^t*x, b1 <= Ax <= b2, x>=0

can someone help me?

What have you tried so far?

Well, I know how we can transform from standard form to canonical form.. And I think that we must transform vector b or matrix A, but not sure how because i havent seen exercises in this form..

What is the

**definition**of "dual" of a linear programming problem? That would seem the best place to start! - November 20th 2013, 06:31 AMmboricgsRe: Linear programming
(P) max{z^t*x|Ax<=0} (D) min{y^t*b|y>=0, y^tA=z^t}
