How to do DUALITY in LPP: Operations Research Techniques: by G N Satish Kumar

Formulation of Dual Linear programming problem:
The dual problem is an Linear Programming problem defined directly and systematically from the primal Linear Programming model. The two problems are so closely related that the optimal solution of one problem automatically provides the optimal solution to the other.
In this video I have clearly explained the formulation of dual LPP from Primal LPP.
This video is a part of “Operations Research” series.
The main aim of these series of videos are to make clear the fundamentals of Operation Research and its techniques used in different fields of Interest.
I hope these videos will be useful for the students as well as for the professionals in their respective fields of Interest. Students of Mathematics, Statistics, Operations Research, Engineering, Economics and Management whose course of study include some or all the topics presented in these videos will be benefited.
