Nowadays high fuzzy utility based pattern mining is an emerging topic in data mining. It refers to discover all patterns having a high utility meeting a user-specified minimum high utility threshold. It comprises extracting patterns which are highly accessed in mobile web service sequences. Different from the traditional fuzzy approach, high fuzzy utility mining considers not only counts of mob...

We study a special class of cooperative games with transferable utility (TU), called -attribute games. Every player in an game is endowed vector attributes that can be combined additive fashion; is, if players form coalition, the attribute this coalition obtained by adding its members. Another fundamental feature their characteristic function defined continuous —the value depends only on evalua...

A multicoalitional bargaining problem is a non-transferable utility game and for each coalition, a bargaining rule. We look for ordinally invariant solutions to such problems and discover a subrule of Bennett’s (1997, Games Econ. Behav. 19, 151–179) that satisfies the property. On a subclass of problems that is closely related to standard bargaining problems and allocation problems with majorit...

Abstract This paper studies matching markets in the presence of middlemen. In our framework, a buyer–seller pair may either trade directly or use services middleman; and middleman serve multiple pairs. For each such market, we examine associated TU game. We first show that, context, an optimal can be obtained by considering two-sided assignment market where is allowed to mediation any free char...

In this paper, the generalized forms of the fuzzy core and the Shapley function for dynamic fuzzy games on matroids are given. An equivalent form of the fuzzy core is researched. In order to better understand the fuzzy core and the Shapley function for dynamic fuzzy games on matroids, we pay more attention to study three kinds of dynamic fuzzy games on matroids, which are named as fuzzy games w...

Cooperative games are real-valued lattice functions quantifying the TU (transferable utility) worth of cooperation within a (finite) player set. A fundamental issue is how to share this worth amongst the players, i.e., the solution problem. Although cooperative games were originally conceived exclusively in terms of coalitional games, associating a worth to each coalition, later more complex ga...

In hedonic games, a set of n agents, having preferences over all possible coalition structures, needs to agree on stable outcome. this work, we initiate the study games with fixed-size coalitions, where structures is restricted as follows: there are k each has fixed size, and sum sizes coalitions equals n. We focus basic model additively separable symmetric preferences, an agent's preference ca...

The transferable utility hypothesis underlies important theoretical results in household economics. We provide a revealed preference framework for bringing this (theoretically appealing) hypothesis to observational data. We establish revealed preference conditions that must be satisfied for observed household consumption behavior to be consistent with transferable utility. We also show that the...
