查询词典 tangent

The relationships between sub- and super-derivatives and Penot diferentials are dicussed as well.4. In recent years, set-valued optimization make much progress. In Chapter 5, based on Clarke tangent cone, we establish epiderivative of a class of set-valued maps and its properties.

在第5章中，针对近几年发展起来的集值优化，基于Clarke切锥利用Epigraph建立了一类集值映射的Epi-导数并讨论它的一些性质，同时给出集值优化的充分的最优性条件。
