You can also notice that this is the only nontrivial constraint in the dual program - the other constraints are satisfied merely by the $w_1,w_2\le 0$ requirement. Algorithm C: Convert a primal standard to a dual standard. Knowing the optimal objective value can help (given this, simply find the primal feasible point with that objective value), as can knowing which primal variables are 0. 0000059074 00000 n So, the primal is: maximize z = 3 x + 4 y such that: x + y 450 and 2 x + y 600 x, y 0 which is equivalent to: minimize z = 3 x 4 y such that: x + y 450 and 2 x + y 600 x, y 0 I made w2=w4-w5 and w3=-w6 and converted to standard form both at once introducing .

Duality in Linear Programming | Primal to Dual Conversion | LPP Ax \geq b, x \geq 0$$ 0000059911 00000 n @blob Sorry, I actually know quite little about linear programming - I solved this question with basic calculus which was easy to do because I only had one nontrivial constraint to deal with. Notice that $g=0$ isn't a possibility because if $g=0$ then we have $w_1=w_2=0$ which then does not satisfy the constraint Show that converting PC (primal canonical) to DC (dual canonical) is similar when done directly or when done via canonical to standard conversion (i.e. Extracting arguments from a list of function calls.
