中小私营企业信用行为演化研究

运用演化经济学理论,通过建立中小私营企业信用行为演化博弈模型,研究中小私营企业信用行为演化规律,并用计算机仿真技术展示信用行为的演化方向。研究发现:如果中小私营企业追求短期利益、缺乏第三方公正的惩罚及失信后资产损失小,会造成中小私营企业信用行为演化成不良“锁定”状态。     

局部G-凸空间内的广义矢量拟平衡问题

在局部G-凸空间内引入和研究了几类广义矢量拟平衡问题(GVQEP)．包含了大多数广义矢量平衡问题,广义矢量变分不等式问题,拟平衡问题和拟变分不等式问题作为特殊情形．首先在局部G-凸空间内对一人对策证明了一个平衡存在性定理．作为应用,在非紧局部G-凸空间内对GVQEP的解建立了某些新的存在定理．这些结果和论证方法与最近文献中的结果和论证方法相比较是新的和完全不同的．     

LINEAR QUADRATIC NONZERO-SUM DIFFERENTIAL GAMES WITH RANDOM JUMP

The existence and uniqueness of the solutions for one kind of forward-backward stochastic differential equations with Brownian motion and Poisson process as the noise source were given under the monotone conditions.Then these results were applied to nonzero-sum differential games with random jumps to get the explicit form of the open-loop Nash equilibrium point by the solution of the forward-backward stochastic differential equations.

Quantum Game with Restricted Matrix Strategies

We study a quantum game played by two players with restricted multiple strategies. It is found that in this restricted quantum game Nash equilibrium does not always exist when the initial state is entangled. At the same time,we find that when Nasli equilibrium exists the payoff function is usually different from that in the classical counterpart except in some special cases. This presents an explicit example showing quantum game and classical game may differ.When designing a quantum game with limited strategies, the allowed strategy should be carefully chosen according to the type of initial state.     

Scheme for Implementation of Quantum Game in Cavity QED

We propose an experimentally feasible scheme to implement two-player quantum game in cavity quantum electrodynamics （QED）. During the process, the cavity is only virtually excited, thus our scheme is insensitive to the cavity field states and cavity decay. The scheme can be realized in the range of current cavity QED techniques.     

基于体感技术的游戏重构框架的应用研究

为满足体感游戏市场需求,降低3D游戏前期投入风险,文章提出通过开发中间件模块对游戏开发过程进行简单改造,实现3D游戏向体感游戏平滑过渡的过程。先是简单介绍了体感技术的原理和工作过程,接着结合Kinect硬件系统提出了3D游戏到体感游戏重构框架（3D-MS重构框架）,然后设计和实现了中间件模块,并对现有3D游戏的提出具体改进策略和方法。最后以《神龙》游戏为案例进行了重构和实验测试,实验表明3D-MS重构框架是可行的,采用中间件技术可平滑、快速实现从3D游戏到体感游戏,比直接改造游戏的效率高2.2倍,同时能提高游戏的人机互动效果。     

A general framework for cooperation under uncertainty

In this paper, we introduce a general framework for situations with decision making under uncertainty and cooperation possibilities. This framework is based upon a two stage stochastic programming approach. We show that under relatively mild assumptions the associated cooperative games are totally balanced. Finally, we consider several example situations.     

Monotonicity in the stock competition game with consumer search

Anupindi and Bassok investigate the impact of centralizing the stocks in a one-manufacturer-two-retailer supply chain with consumer search. They observed through numerical studies that in the decentralized scenario, the retailers’ order quantities are monotonic in the consumer search probability. This paper provides an analytical justification of this monotonicity.
