【Abstract】 In order to improve the characteristics of the ineffective variables and ineffective constraints,the relations between the ineffective variables and ineffective constraints were discussed.It was proved that the theorems of identifying ineffective variables and ineffective constraints which are the theoretical base of the method of identifying and eliminating further ineffective variables and ineffective constraints in solving linear programming.更多还原
