Max 3x1+2x2
s.t. 6x1+3x2 <=42
3x1+4x2<=36
x1,x2>=0
a) write the dual problem of the above primal problem and define the physical meaning of the dual objective function and the dual constraints
Since 2nd constraint in the primal is equality, the corresponding dual variable y2 will be unrestricted in sign.
So,dual of given problem is
Min 42(y1)+36(y2)
S.t.
6y1+3y2≥3
3y1+4y2≥2
And y1≥0,y2 restricted in sign.
