连续博弈中至少存在一个混合策略Nash均衡,但是关于无限策略混合策略Nash均衡的解法,以及局中人的策略集或是效益函数是不确定性博弈均衡问题,国内外相关的研究成果还比较少。运用粒子群算法对目标函数没有严格要求,参数较少,编码简单的优势,创立了一种计算无限策略混合策略的近似算法;并在此基础上提出了粗糙博弈论的概念,以粗糙集和Vague集的理论为基础,发现了一种粗糙博弈论转化为经典博弈论的方法。无限策略混合策略Nash均衡的近似算法和粗糙博弈论的研究为策略集和效益函数不确定时的博弈问题提供了理论依据。算法示例结果表明,基于改进的粒子群算法的无限策略混合策略Nash均衡近似算法和粗糙博弈论的解法是有效可行的。  相似文献

在N人非合作博弈Nash均衡问题求解过程中,将量子不确定性原理、协同演化以及免疫算法内的抗体浓度抑制机制引进到经典粒子群算法中,设计了一种新型改进量子粒子群算法来更好地处理Nash均衡问题。该算法在运算过程中,运用抗体浓度以及协同演化的方式来维系粒子群具备的多样性特征,并借助量子不确定性缩减迭代搜索耗时。该算法不仅有效地将粒子群算法运算简单与方便实现的特质承继下来,而且算法的收敛速度以及其全局搜索能力都获得了大幅度的提升。相关数值算例分析表明,改进的算法能够更好地处理粒子早熟,相较遗传算法以及免疫粒子群算法更具性能优越性。  相似文献

提出一种求解N人有限非合作博弈Nash均衡的群体智能算法—烟花算法(FWA)。烟花爆炸后产生爆炸火花和高斯变异火花,根据火花的适应度值的好坏产生下一代烟花,适应度值较好的火花在较小范围内产生较多的爆炸火花,反之,适应度值较差的火花在较大范围内产生较少的爆炸火花。通过高斯变异火花增加种群的多样性,这种爆炸搜索机制对较好火花附近的区域搜索更加彻底并且避免过早陷入局部寻优。实验结果表明,烟花算法在求解N人有限非合作博弈Nash均衡问题上优于免疫粒子群算法。  相似文献

现有的图型博弈Nash均衡求解方法基本是在离散化剖面空间中搜索求解,最终只能得到近似Nash均衡。针对现有求解方法存在的不足,把求解图型博弈的Nash均衡看作是连续策略空间中的函数优化问题,定义Agents在策略剖面中的效用偏离度之和为优化目标,其最优解就是博弈的Nash均衡。本文基于对实例的分析指出目标函数下降梯度的计算可归结为一组线性规划,进而提出一种求解图型博弈Nash均衡的新型梯度下降算法。算法分析及实验研究表明,对于多Agent交互模型中的相关问题,本文提出的方法可求解任意图结构图型博弈Nash均衡,对于大规模图型博弈也有较好的求解精度和求解效率。  相似文献

Abstract This paper describes an approach to the design of interactive multimedia materials being developed in a European Community project. The developmental process is seen as a dialogue between technologists and teachers. This dialogue is often problematic because of the differences in training, experience and culture between them. Conditions needed for fruitful dialogue are described and the generic model for learning design used in the project is explained.  相似文献

European Community policy and the market   总被引:1,自引:0,他引:1  
Abstract This paper starts with some reflections on the policy considerations and priorities which are shaping European Commission (EC) research programmes. Then it attempts to position the current projects which seek to capitalise on information and communications technologies for learning in relation to these priorities and the apparent realities of the marketplace. It concludes that while there are grounds to be optimistic about the contribution EC programmes can make to the efficiency and standard of education and training, they are still too technology driven.  相似文献

Development of software intensive systems (systems) in practice involves a series of self-contained phases for the lifecycle of a system. Semantic and temporal gaps, which occur among phases and among developer disciplines within and across phases, hinder the ongoing development of a system because of the interdependencies among phases and among disciplines. Such gaps are magnified among systems that are developed at different times by different development teams, which may limit reuse of artifacts of systems development and interoperability among the systems. This article discusses such gaps and a systems development process for avoiding them.  相似文献

This paper presents control charts models and the necessary simulation software for the location of economic values of the control parameters. The simulation program is written in FORTRAN, requires only 10K of main storage, and can run on most mini and micro computers. Two models are presented - one describes the process when it is operating at full capacity and the other when the process is operating under capacity. The models allow the product quality to deteriorate to a further level before an existing out-of-control state is detected, and they can also be used in situations where no prior knowledge exists of the out-of-control causes and the resulting proportion defectives.  相似文献

Going through a few examples of robot artists who are recognized worldwide, we try to analyze the deepest meaning of what is called “robot art” and the related art field definition. We also try to highlight its well-marked borders, such as kinetic sculptures, kinetic art, cyber art, and cyberpunk. A brief excursion into the importance of the context, the message, and its semiotics is also provided, case by case, together with a few hints on the history of this discipline in the light of an artistic perspective. Therefore, the aim of this article is to try to summarize the main characteristics that might classify robot art as a unique and innovative discipline, and to track down some of the principles by which a robotic artifact can or cannot be considered an art piece in terms of social, cultural, and strictly artistic interest. This work was presented in part at the 13th International Symposium on Artificial Life and Robotics, Oita, Japan, January 31–February 2, 2008  相似文献

Although there are many arguments that logic is an appropriate tool for artificial intelligence, there has been a perceived problem with the monotonicity of classical logic. This paper elaborates on the idea that reasoning should be viewed as theory formation where logic tells us the consequences of our assumptions. The two activities of predicting what is expected to be true and explaining observations are considered in a simple theory formation framework. Properties of each activity are discussed, along with a number of proposals as to what should be predicted or accepted as reasonable explanations. An architecture is proposed to combine explanation and prediction into one coherent framework. Algorithms used to implement the system as well as examples from a running implementation are given.  相似文献
