| Abstract: | This paper proposes a principle of new algorithm for linear programming based on saddle point. The convergence and choice of the step size under the condition of the changeless base set is discussed. The computational complexity is q-linear. The NETLIB problems were computed by using the proposed algorithm and the interior-point working code PCx respectively, and results were compared. This code has been successfully used to solve problems in petrochemical industry. |
