本文给出了一类拟可微函数的拟微分映射的Demyanov和的上半连续性的结果,并利用Demyanov和,对具有不等式约束的拟可微函数的极小问题,给出了一个可行的下降方向.
The upper semi-continuity of Demyanov sum of quasidifferential mappings for a class of quasidifferentiable functions is presented and a kind of feasible descent direction, generated via Demyanov sum, for minimizing a quasidifferentiable function with inequality constraints is given.
