1·Objective To investigate the diagnosis and treatment of multiple primary colorectal carcinoma(MPCC).

目的探讨多原发性结直肠癌的诊断治疗。

2·As the non-degeneracy condition holds and the smoothing parameter tends to zero, an S-stationary point of the MPCC problem is equivalent to a KKT point of the smoothing nonlinear programming.

当非退化条件成立和磨光参数趋于零时，证明了原问题的S -稳定点与磨光非线性规划的KKT点等价。
