The purpose of this paper is to introduce a class of maximal monotone operators on Banach spaces that contains all maximal monotone operators on reflexive spaces, all subdifferential operators of proper, lsc, convex functions, and, more generally, all maximal monotone operators that verify the simplest possible sum theorem. Dually strongly maximal monotone operators are also contained in this class. We shall prove that if T is an operator in this class, then
(the norm closure of its domain) is convex, the interior of co(dom(T)) (the convex hull of the domain of T) is exactly the set of all points of
at which T is locally bounded, and T is maximal monotone locally, as well as other results. 相似文献

To solve nonlinear complementarity problems (NCP), the logarithmic-quadratic proximal (LQP) method solves a system of nonlinear
equations at each iteration. In this paper, the iterates generated by the original LQP method are extended by explicit formulas
and thus an extended LQP method is presented. It is proved theoretically that the lower bound of the progress obtained by
the extended LQP method is greater than that by the original LQP method. Preliminary numerical results are provided to verify
the theoretical assertions and the effectiveness of both the original and the extended LQP method. 相似文献

We consider the standard linear complementarity problem (LCP): Find (x, y) R
2n
such that y = M
x + q, (x, y) 0 and x
i
y
i = 0 (i = 1, 2, ... , n), where M is an n × n matrix and q is an n-dimensional vector. Recently several smoothing methods have been developed for solving monotone and/or P
0 LCPs. The aim of this paper is to derive a complexity bound of smoothing methods using Chen-Harker-Kanzow-Smale functions in the case where the monotone LCP has a feasible interior point. After a smoothing method is provided, some properties of the CHKS-function are described. As a consequence, we show that the algorithm terminates in
Newton iterations where
is a number which depends on the problem and the initial point. We also discuss some relationships between the interior point methods and the smoothing methods. 相似文献

Monotone variational inequality problems with box constraints and complementarity problems are reformulated as simple-bound optimization problems. Some derivative-free methods for these problems are proposed. It is shown that, for these new methods, the updated point sequence remains feasible with respect to its simple constraints if the initial point is feasible. Under certain conditions, these methods are globally convergent. 相似文献
