On convergence properties of a least-distance programming procedure for minimization problems under linear constraints 总被引:3,自引:0,他引:3
G. L. Xue 《Journal of Optimization Theory and Applications》1986,50(2):365-370
In Ref. 1, Bazaraa and Goode provided an algorithm for solving a nonlinear programming problem with linear constraints. In this paper, we show that this algorithm possesses good convergence properties.This paper was written under the guidance of Associate Professor C. Y. Wang. The author takes great pleasure in thanking him. 相似文献

This paper proposes a computational game-theoretic model for the international negotiations that should take place at the
end of the period covered by the Kyoto protocol. These negotiations could lead to a self-enforcing agreement on a burden sharing
scheme given the necessary global emissions limit that will be imposed when the real extent of climate change is known. The
model assumes a non-cooperative behavior of the parties except for the fact that they will be collectively committed to reach
a target on total cumulative emissions by the year 2050. The concept of normalized equilibrium, introduced by J.B. Rosen for
concave games with coupled constraints, is used to characterize a family of dynamic equilibrium solutions in an m-player game where the agents are (groups of) countries and the payoffs are the welfare gains obtained from a Computable General
Equilibrium (CGE) model. The model deals with the uncertainty about climate sensitivity by computing an S-adapted equilibrium. These equilibria are computed using an oracle-based method permitting an implicit definition of the
payoffs to the different players, obtained through simulations performed with the global CGE model GEMINI-E3.

Monte Carlo and quasi-Monte Carlo sampling methods for a class of stochastic mathematical programs with equilibrium constraints 总被引:1,自引:0,他引:1

In this paper, we consider a class of stochastic mathematical programs with equilibrium constraints introduced by Birbil et al.
(Math Oper Res 31:739–760, 2006). Firstly, by means of a Monte Carlo method, we obtain a nonsmooth discrete approximation
of the original problem. Then, we propose a smoothing method together with a penalty technique to get a standard nonlinear
programming problem. Some convergence results are established. Moreover, since quasi-Monte Carlo methods are generally faster
than Monte Carlo methods, we discuss a quasi-Monte Carlo sampling approach as well. Furthermore, we give an example in economics
to illustrate the model and show some numerical results with this example.

This article discusses feasibility conditions in mathematical programs with equilibrium constraints (MPECs). The authors prove that two sufficient conditions guarantee the feasibility of these MPECs. The authors show that the two feasibility conditions are different from the feasibility condition in [2, 3], and show that the sufficient condition in [3] is stronger than that in [2]. 相似文献

In this paper, we deal with the generation of bundles of loads to be submitted by carriers participating in combinatorial auctions in the context of long-haul full truckload transportation services. We develop a probabilistic optimization model that integrates the bid generation and pricing problems together with the routing of the carrier’s fleet. We propose two heuristic procedures that enable us to solve models with up to 400 auctioned loads. 相似文献

Production optimization of gas-lifted oil wells under facility, routing and pressure constraints is a challenging problem, which has attracted the interest of operations engineers aiming to drive economic gains and scientists for its inherent complexity. The hardness of this problem rests on the non-linear characteristics of the multidimensional well-production and pressure-drop functions, as well as the discrete routing decisions. To this end, this work develops several formulations in Mixed-Integer Linear Programming (MILP) using multidimensional piecewise-linear models to approximate the non-linear functions with domains spliced in hypercubes and simplexes. Computational and simulation analyses were performed considering a synthetic but realistic oil field modeled with a multiphase-flow simulator. The purpose of the analyses was to assess the relative performance of the MILP formulations and their impact on the simulated oil production. 相似文献

We prove an existence theorem of Lagrange multipliers for an abstract control problem in Banach spaces. This theorem may be applied to obtain optimality conditions for control problems governed by partial differential equations in the presence of pointwise state constraints. 相似文献

In this note, we obtain a sufficient and necessary condition for a point to be a local minimizer of a continuous optimization problem with maximin constraints via the local minimizers of its transformed standard nonlinear optimization problem. 相似文献
