In this time I would like to share to you some problem sets and solution about linear programming. These problem sets consist of the simplex method problems, the two- phase simplex method problems, the duality problems, the simplex theory, and transportation problems. By the following link you can download those problem set and its solution. Hope you can gain advantages from this post. If you have some critics, suggestions, etc, please feel free to leave your comment or you can contact me by e-mail or Facebook. See you and have a nice day.
