Generalized derivatives and its application
广义导数及其应用
We also propose a bfgs method for solving the nonsmooth equation reformulation of the kkt system of the symmetric variational inequality problem . we introduce a parameter in the non - monotone line search . by changing the parameter in a suitable way , we get a descent direction of the bfgs method
对对称变分不等式的kkt系统等价的非光滑方程组，我们利用函数的半光滑性质及其广义导数的某种对称性质，得到相应的bfgs法的一个下降方向。
