This paper describes the dual simplex method, dual simplex method algorithm structure is simple , easy to use matlab programming. In this experiment , I first analysis of the dual simplex method , understanding of the dual simplex method for solving the dual problem in steps and examples to solve , and then apply to the idea of ??dual simplex method of writing code , conduct matlab examples solved analyze , summarize . For algorithm comparison. I put the dual simplex method are compared with the simplex method , the first step to understand the simplex method to solve the problem solving process and examples , and then write code to analyze an example , last and dual simplex method for comparison. By comparison, I found the simplex method is feasible to the original problem from one iteration to another feasible solution by solution , until the number of test optimality condition is satisfied. Dual simplex rule of thumb is to satisfy the dual feasibility conditions from the gradual departure of the original problem through an iterative search for the optimal solution . Remain in an iterative process based solutions for dual feasibility , leaving the infeasibility gradually disappear.
