Saddle Point Optimality Conditions for Programming Problems with B-(p,r)-invexity Functions
摘要/Abstract
B-(p,r)-不变凸函数是一类新的广义凸函数,它既是不变B-凸函数又是(p,r)-不变凸函数的推广形式,从而也是熟知的凸函数和不变凸函数的推广形式.首先介绍了一个广义Lagrange向量函数L(x,u),并利用B-(p,r)-不变凸函数讨论了多目标分式规划问题的鞍点最优性条件,其结果具有一般性,推广了许多涉及不变凸函数、不变B-凸函数和(p,r)-不变凸函数的文献的结论.
B-(p,r)-invexity functions are new generalized invex functions.It is the generalization of the B-invexity functions and(p,r)-invexity functions,thus it is also the generalization of well known convexity functions and invexity functions.A vector valued Lagrangian L(x,u)is introduced firstly,and by using B-(p,r)-invexity functions,the saddle point optimality conditions of a multiobjective fractional programming problem are established.The work generalizes many results on programming problems with invex functions,B-invexity functions and(p,r)-invexity functions.
