COMPUTERS & MATHEMATICS WITH APPLICATIONS 2014年 第5期67卷 999-1015页
作者: Zhao, Jian Xun Tianjin Univ Sch Sci Dept Math Tianjin 300072 Peoples R China
We consider a class of complementarity problems involving functions which are nonlinear. In this paper we reformulate this nonlinear complementarity problem as a system of absolute value equations (which is nonsmooth)... 详细信息
