The effect of cash dividend initiations on the long-run market value of the companies;

Method for uncertain multiple attribute decision making based on estimation of attribute value functions;

In each-subproblem,high-dimensional state variable is used to denote the information of random travel times,and approximations of the value function are used to sol.

Empirical research on prospect theory and cost function;

It can be used for solving multi-objective problems with a concave ob-iective and cost functions and a convex feasible region, The program of the algorithm is writ-ten in ANSIC language and has been successfully run on IBM P/IAT-286 and 386 machines.

In this paper,we first discuss the method for solving nonlinear complementarity problem with the equivalent formulation of minimization based on merit function.

In order to avoid the Maratos effect,the merit functions used are approximations to Flether s differentiable exact penalty function,and the algorithm updates approximations to one-sided reduced Hessian and two-sided reduced Hessian seperately.

In this paper,based on Fischer-Burmeister SDCP-function,we propose a merit function for the optimality conditions for semidefinite programming(SDP),and present a PRP-type conjugate gradient algorithm after analyzing its properties.
