摘要:

通过定义函数之间“同定”和“同序”两种关系, 讨论这两种关系的相关性质, 并在此基础上证明了在上述关系下, 拟凸函数和伪凸函数凝聚后仍分别为拟凸函数和伪凸函数的充分条件.

关键词: 优化, 凝聚函数, 拟凸函数, 伪凸函数

Abstract:

On the basis of two relations between functions  defined as same positive definite relation and same order relation the properties of the two relations were discussed. Besides a sufficient condition was established to assure that a new quasiconvex function was formed by the quasiconvex functions aggregated, and a sufficient condition was proposed to guarantee that quasiconvex functions were aggregated to form a new pseudoconvex function.

Key words: optimization, aggregate function, quasiconvex function, pseudoconvex function
