Hi, I am trying to convert a primal LP problem into it's corresponding dual. $$ \text{ such that } a+2b 3 \text{ and }a+b 4;$$, the optimal solution of dual becomes $a=4$; $b=0$; $c=1$ (surplus variable). $$\text{ such that: } x+y 450 \text{ and } 2x+y 600$$ Furthermore, we declare a su cient and necessary condition for duality gap equal to 0. Now to convert this to a standard form I am stuck because I introduced y2=y4-y5, y3=-y6 and slack and surplus variables from constraints 1 and 2 respectively. 0000011658 00000 n When calculating CR, what is the damage per turn for a monster with multiple attacks?
