## Primal dual relationship operation research free

I'm currently studying operations research and I want to know and understand how we find an optial solution to the dual problem with minimum effort. Lets say we have this primal and dual problem: Relations between Primal and Dual If the primal problem is Maximize ctx subject to Ax b, x 0 then the dual is Minimize bty subject to Aty c (and y unrestricted) Easy fact: If x is feasible for the primal, and y is feasible for the dual, then ctx bty So (primal optimal) (dual optimal) (Weak Duality Theorem) Much less easy fact: (Strong Duality Theorem)**primal dual relationship operation research** Duality in linear programming is essentially a unifying theory that develops the relationships between a The constraining resources of the production operation are the metalworking and woodworking capacities dual of the dual is the primal. This is an important result since it implies that the dual may be solved instead

Every linear programming problem, referred to as a primal problem, can be converted into a dual problem, which provides an upper bound to the optimal value of the primal problem. In matrix form, we can express the primal problem as: . Maximize c T x subject to Ax b, x 0; with the corresponding symmetric dual problem, Minimize b T y subject to A T y c, y 0. *primal dual relationship operation research* Jul 14, 2010 Lecture Series on Fundamentals of Operations Research by Prof. G. Srinivasan, Department of Management Studies, IIT Madras. Lec9 Primal Dual Relationships, Duality Theorems PRIMALDUAL RELATIONSHIPS. Changes made in the original LP model will change the elements of the current optimal tableau, which in turn may affect the optimality andor the feasibility of the current solution. This section introduces a number of primaldual relationships that can be used to recompute the elements of the optimal simplex tableau. Mar 06, 2017 The original LP problem is referred to as the primal. In this video, I'll explain their relationships and how to find the dual from the primal.
