with the mechanics of implementing the dual simplex method in the tableau format. We will see that the dual simplex algorithm is very similar to the primal simplex algorithm. Algorithm With reference to the tableau, the algorithm must begin with a basic solution that is dual feasible so all the elements of row 0 must be nonnnegative.

However, for problems involving more than two variables or problems involving a large number of constraints, it is better to use solution methods that are adaptable to computers. simplex method moves from one better solution to another until the best one is found, and then it stops. The manual solution of a linear programming model using the simplex method can be a lengthy and tedious process.Years ago, manual application of the simplex method was the only means for solving a linear programming problem. 10. THE DUAL SIMPLEX METHOD. In Section 5, we have observed that solving an LP problem by the simplex method, we obtain a solution of its dual as a by-product. Vice versa, solving the dual we also solve the primal. This observation is useful for solving problems such as maximize 4x 1 8x 2 9x 3 subject to 2x 1 x 2 x 3 1 3x 1 4x 2 + x 3 3 5x 1 2x ...
