把随机过程分析引入Lanchester方程就形成了随机格斗理论.运用随机格斗理论研究了潜艇协同隐蔽攻击水面舰艇编队获胜概率的数学模型,利用状态转移图和Laplace变换的性质推导出了2对2搜索型随机格斗中双方的获胜概率公式,并结合潜艇协同隐蔽攻击水面舰艇的实际,计算分析了格斗双方的获胜概率.利用这一公式可以得到概率上的精确解,能够被用来定量评估潜艇协同隐蔽攻击水面舰艇编队的作战效能. 相似文献

在体育比赛中 ,一局定胜负 ,虽然比赛双方获胜的概率均为二分之一 ,但是由于实验的次数太少 ,偶然因素较多 ,不能较好地展示双方实力 ,故这种赛制难以使参赛者信服 ,不能展现胜者风范 .而比赛组织者普遍采用的“三局两胜”或“五局三胜”制决定胜负的方法 ,既令参赛选手满意 ,又被观众所接受 .那么 ,这种比赛制度公平吗 ?下面用概率的观点和知识加以阐述 .由于一场比赛前两位选手的水平或胜率是一个不可测的未知数 ,因此 ,赛事组织者理应撇开比赛中甲、乙双方的原有水平 ,而认为在一次比赛中甲、乙双方获胜的概率各为 p=12 ,即在一局比赛中… 相似文献

A core selection is a function which for each cooperative game with non-empty core selects a subset, possibly a single element,
of the core. In this paper, we study selections which maximize some function or binary relation on the core. We present an
axiomatic characterization of such core selections, as well as a local characterization using duality which can be applied
to investigate properties of core selections. We give an application of the local characterization to a question of coalitional
monotonicity of core selections. 相似文献

Abstract The problem of (partial) hedging contingent claims for a single agent is well studied. This paper studies the problem for the multiagent case in incomplete markets. For this case, a cooperative hedging game is posed as follows: First, all agents contribute some money and collect the money together as the initial total capital, then invest the initial total capital in a trading strategy, and, finally, divide the terminal wealth of the trading strategy and each of them gets a part. We give a characterization of the optimal cooperative hedging strategy and prove that the core of the cooperative hedging game, as a cooperative game with side payment, is nonempty. 相似文献

In this paper, we present a topological duality for partially ordered sets. We use the duality to give a topological construction of the canonical extension of a poset, and we also topologically represent the quasi-monotone maps, that is, maps from a finite product of posets to a poset that are order-preserving or order-reversing in each coordinate. 相似文献

We introduce and study the subdifferential of a function at a point, with respect to a primal-dual pair of optimization problems, which encompasses, as particular cases, several known concepts of subdifferential. We give a characterization of optimal solutions of the primal problem, in terms of abstract Lagrangians, and a simultaneous characterization of optimal solutions and strong duality, with the aid of abstract subdifferentials. We give some applications to unperturbational Lagrangian duality and unperturbational surrogate duality.We wish to thank H. J. Greenberg for discussions and valuable remarks on the subject of this paper, made during his visit in Bucharest, in May 1985, within the framework of the Cooperative Exchange Agreement between the National Academy of Sciences of the USA and the Romanian Academy of Sciences. 相似文献

On duality theory in multiobjective programming 总被引:5,自引:0,他引:5
D. T. Luc 《Journal of Optimization Theory and Applications》1984,43(4):557-582
In this paper, we study different vector-valued Lagrangian functions and we develop a duality theory based upon these functions for nonlinear multiobjective programming problems. The saddle-point theorem and the duality theorem are derived for these problems under appropriate convexity assumptions. We also give some relationships between multiobjective optimizations and scalarized problems. A duality theory obtained by using the concept of vector-valued conjugate functions is discussed.The author is grateful to the reviewer for many valuable comments and helpful suggestions. 相似文献

Baker and Norine proved a Riemann–Roch theorem for divisors on undirected graphs. The notions of graph divisor theory are in duality with the notions of the chip-firing game of Björner, Lovász and Shor. We use this connection to prove Riemann–Roch-type results on directed graphs. We give a simple proof for a Riemann–Roch inequality on Eulerian directed graphs, improving a result of Amini and Manjunath. We also study possibilities and impossibilities of Riemann–Roch-type equalities in strongly connected digraphs and give examples. We intend to make the connections of this theory to graph theoretic notions more explicit via using the chip-firing framework. 相似文献

Recently, the concept of classical bargaining set given by Aumann and Maschler in 1964 has been extended to fuzzy bargaining set. In this paper, we give a modification to correct some weakness of this extension. We also extend the concept of the Mas-Colell's bargaining set (the other major type of bargaining sets) to its corresponding fuzzy bargaining set. Our main effort is to prove existence theorems for these two types of fuzzy bargaining sets. We will also give necessary and sufficient conditions for these bargaining sets to coincide with the Aubin Core in a continuous superadditive cooperative fuzzy game which has a crisp maximal coalition of maximum excess at each payoff vector. We show that both Aumann-Maschler and Mas-Colell fuzzy bargaining sets of a continuous convex cooperative fuzzy game coincide with its Aubin core. 相似文献

On Linear Programming Duality and Necessary and Sufficient Conditions in Minimax Theory 总被引:1,自引:0,他引:1

In this paper we discuss necessary and sufficient conditions for different minimax results to hold using only linear programming
duality and the finite intersection property for compact sets. It turns out that these necessary and sufficient conditions
have a clear interpretation within zero-sum game theory. We apply these results to derive necessary and sufficient conditions
for strong duality for a general class of optimization problems.
The authors like to thank the comments of the anonymous referees for their remarks, which greatly improved the presentation
of this paper. 相似文献

In this paper we consider linear generalized Nash equilibrium problems, i.e., the cost and the constraint functions of all players in a game are assumed to be linear. Exploiting duality theory, we design an algorithm that is able to compute the entire solution set of these problems and that terminates after finite time. We present numerical results on some academic examples as well as some economic market models to show effectiveness of our algorithm in small dimensions. 相似文献
