查询词典 difficult problem

In Chapter 2, we consider the error bound and the auxiliary problem algorithm for the generalized linear complementarity problem over a polyhedral cone: First, we give an absolute and a relative global error bound for GLCP and nondegenerate GLCP, respectively, and then we explore the properties of the solution set of the problem, based on which we establish another absolute and relative error bound for GLCP which is much exacter compared with the result above.

第二章主要研究了闭凸锥上广义线性互补问题的误差界及基于其上的一个求解GLCP的辅助问题算法：(1)给出了GLCP的全局绝对误差界和在有非退化解时的全局绝对误差界及其相对误差界；(2)对GLCP的解集结构进行了探讨，并利用得到的结果给出了GLCP的另一个全局绝对误差界和相对误差界估计；(3)我们提出了一个求解GLCP的辅助问题算法，并证明在适当条件下该算法具有全局收敛性。
