We present a series of non-cooperative games with monotone best replies whose set of Nash equilibria coincides with the set of stable matchings. Key features of stable matchings are established as familiar properties of games with monotone best replies. Then we present a sense in which our method is necessary for the monotonicity approach. We also establish the connection of our approach with o...

considering the efficiency studies play a role in making available the revise in relative importance, policy reforms and resource management, this study has been accomplished in fish beach seine cooperative companies located in golestan province and used dea approach to measure the technical efficiency (te) and factor effects. the survey data were gathered from 20 farms, which selected via cens...

regarding the recent development in lng production and transportation, lng exports would exhibit a pivotal role in the future of global gas trade. by analyzing the geographical pattern of the world lng trade and the structure of its transportation costs, the lng cost matrix for forum's exporters to main lng importers is presented. using this matrix, the cooperation amongst the forum's...

We analyze the core of a cooperative Cournot game. We assume that when contemplating a deviation, the members of a coalition assign positive probability over all possible coalition structures that the nonmembers can form. We show that when the number of firms in the market is sufficiently large then the core of the underlying cooperative game is non-empty. Moreover, we show that the core of our...

Combinatorial optimization problems confront us with the problem of searching in a huge connguration space. Associated with each of these conngura-tions is the value of a utility function and the optimization task generally consists of nding the connguration which has either the lowest or the highest cost of all. Among the most diicult of these problems are those which belong to the NP-complete...

Competitive analysis is traditionallyused to bound the worst-case performance of two-phase waiting, a common algorithm in multiprocessor environments. Despite the popularity of competitive algorithms, we observe that their assumptions are not valid in closed systems in which processes can influence their future waiting times. By evaluating implicit coscheduling on time-shared, communicating pro...

``Cooperative information system management'' refers to the capacity of several computing systems to communicate and cooperate in order to acquire, store, manage, query data and knowledge. Current solutions to the problem of cooperative information management are still far from being satisfactory. In particular, they lack the ability to fully model cooperation among heterogeneous systems accord...

Network services must self-adapt dynamically in order to accommodate available resources, system errors, and changing requirements. This need for self-reliance will increase with the growing flexibility and heterogeneity that characterizes such network technologies as sensor (ad hoc) networking, grid computing, and pervasive computing. The downside of traditional distributed network management ...

We present a set of problem frames specialized to the area of geographic applications. Problem frames describe the elements of common problems, and help a specifier understand and decompose a complex problem into simpler subproblems for which a solution is often known. We provide an overview of the main issues in geographic applications, and present twelve frames that address many of the proble...
