The Simplex Algorithm

The Simplex Algorithm. LI Xiao-lei. preface. The two-variable LP program can be solved graphically. Most real-life LPs have many variables. In many industrial applications, the simplex algorithm is used to solve LPs with thousands of constraints and variables.

Duality Theory

Duality Theory. LI Xiaolei. Finding the dual of an LP. When taking the dual of a given LP, we refer to the given LP as the primal. If the primal is a max problem, the dual will be a min problem, and vice versa.
