Video created by National Taiwan University for the course "Operations Research (2): Optimization Algorithms". Complicated linear programs were difficult to solve until Dr. George Dantzig developed the simplex method. In this week, we first

The primal Simplex method generates a sequence of primal feasible basic solutions, whereas the dual Simplex method uses only dual feasible basic solutions. Feasiblility is maintained by choosing the pivoting pair (k, ℓ) in each iteration according to the primal and dual quotient rule, respectively. To start such a method, one first needs to

The name of the algorithm is derived from the concept of a simplex and was suggested by T. S. Motzkin. The Simplex Method We have seen that we are at the intersection of the lines x 1 = 0 and x 2 = 0. This is the origin and the two non-basic variables are x 1 and x 2. To move around the feasible region, we need to move off of one of the lines x 1 = 0 or x 2 = 0 and onto one of the lines s 1 = 0, s 2 = 0, or s 3 = 0. The simplex method is one of the most useful and efficient algorithms ever invented, and it is still the standard method employed on computers to solve optimization problems. First, the method assumes that an extreme point is known.

Every book on linear optimization explains the simplex method as a two-stage algorithm: the first for finding a feasible corner as a starting point, and the second

The simplex method is an iterative process in which the Gaussian elimination is repeatedly applied to the coefficient matrix together with the constant column . In each iteration, one column of is selected to be converted to a standard basis vector to replace one of the previous standard basis vectors.
