To circumvent the non - differentiable difficulty caused by the positive homogeneously function that is involved in an equivalent unconstrained formulation for general inequality constrained optimization problems , we turn to the classical lagrangian function and redefine m ( x ) by a conic optimization problem with the lagrangian as the objective function 为了克服不可微正齐次函数( ? | r _ - ~ m )给约束优化问题的等价无约束形式求解带来的困难,我们将其目标函数m ( x )重新用一个以经典拉格朗日函数为目标的锥优化问题来表示。
