An alternative smoothing method for the high dimensional max function
has been studied. The proposed method is a recursive extension of the
two dimensional smoothing functions. In order to analyze the proposed
method, a theoretical framework related to smoothing methods has been
discussed. Moreover, we support our discussion by considering some
application areas. This is followed by a comparison with an
alternative well-known smoothing method.On the Finite Termination of An Entropy Function Based Smoothing Newton Method for Vertical Linear Complementarity Problems

By using a smooth entropy function to approximate the non-smooth max-type function, a vertical
linear complementarity problem (VLCP) can be treated as a family of parameterized smooth
equations. A Newton-type method with a testing procedure is proposed to solve such
a system. We show that the proposed algorithm finds an exact solution of VLCP in a finite
number of iterations, under some conditions milder than those assumed in literature. Some
computational results are included to illustrate the potential of this approach.Entropic Regularization Approach for Mathematical Programs with Equilibrium Constraints

A new smoothing approach based on entropic perturbation
is proposed for solving mathematical programs with
equilibrium constraints. Some of the desirable
properties of the smoothing function are shown. The
viability of the proposed approach is supported by a
computationalstudy on a set of well-known test problems.Solving Variational Inequalities Defined on A Domain with Infinitely Many Linear Constraints
http://repub.eur.nl/pub/219/

We study a variational inequality problem whose domain
is defined by infinitely many linear inequalities. A
discretization method and an analytic center based
inexact cutting plane method are proposed. Under proper
assumptions, the convergence results for both methods are
given. We also provide numerical examples for the
proposed methods.
