please explain it to me clearly 6 Proof of the dual theorem Proof: We will assume that the primal LP is in canonical form Maximize Zr, such that Arb 20 12 Its dual is Minimize W·ry, such that ATy c (no sign constraints on y). Step 1: Suppose xB is the basic variables in the optimal BFS (say r*) f follows from the above discussion that Row (0) of the optimal tableau will be the Prianal LP. It Basic VariableRow2...
Without using the normal form, explicitly write the dual of the following primal problem. Min W = 2y1 + 3y2 s.t. 0.5y1 + 0.25y2 <= 4 y1 + 3y2 >= 20 y1 + y2 = 10 y1, y2 >= 0 b) Using line 0 of the optimal table of the primal, which is below, obtain the solution of the dual problem, that is, obtain the values of the dual variables as well as the optimal value of the objective function...

Primal and Dual Problems Your company grows two types of plants, A and B (e.g., roses and begonias). Both plant types require two types of fertilizer throughout the growing season, Fertilizer 1 and Fertilizer 2.A single plant A will require 2 pounds of fertilizer 1 and 1 pound of fertilizer 2.A single plant B will require 2 pounds of fertilizer 1 and 2 pounds of fertilizer 2.Your distributer has 4000 pounds of fertilizer 1 and 5000 pounds of fertilizer 2...
Exercise 4.22 Consider the dual simplex method applied to a standard form problem with linearly independent rows. Suppose that we have a basis which is primal infeasible, but dual feasible, and let i be such that xB(i) < 0. Suppose that all entries in the ith row in the tableau (other than xB(j)) are nonnegative. Show that the optimal dual cost is +oo.
