摘要
本文利用方向导数对非光滑函数引入了伪凸、严格伪凸和拟凸等概念,给出了非光滑多目标分式规划解的Fritz John型和Kuhn-Tucker型的必要条件和充分条件。
In this paper, several concepts such as pseudoconvex, strict pseudoconvex, and quasiconvex for nonsmooth functions are presented by means of directional derivatives, and then Fritz John and Kuhn-Tucker necessary and sufficient conditions for optimum of nonsmoomth multiobjective fractional programming are derived.
