| Abstract: |
| A variant of Karmarkar's modified algorithm is given for solving Karmarkar's standard linear programming with unknown optimal objective value. By using LDLT factorization of bordering matrix and modified matrix，an efficient method is given. Finally，convergence and complexity of the algorithm are given theoretically. |
