By making algebraically equivalent transformation for the standard centering equation xs = e , we obtain a new system of perturbed k - k - t equations and , for specific power transformation , recover the newton equations that are recently used by j . m . peng et al to show a lower polynomial complexity bound for large - update algorithm 前述的两种方法是针对扰动k一k一t系统进行的,而本文的另一种方法是采用ncp函数,直接将标准线性规划k一k一t条件化为一个不含内点约束的等价方程组,以此改造标准摄动方程组。
