Concise Characteristic Function Representations in Coalitional Games Based on Agent Types

چکیده
Forming effective coalitions is a major research challenge in AI and multi-agent systems. Thus, coalitional games, including coalition structure generation, have been attracting considerable attention from the AI research community. Traditionally, the input of a coalitional game is a black-box function called a characteristic function. In this paper, we develop a new concise representation scheme for a characteristic function, which is based on the idea of agent types. This representation can be exponentially more concise than existing concise representation schemes. Furthermore, this idea can be used in conjunction with existing schemes to further reduce the representation size.

Coalitional Games via Network Flows
We introduce a new representation scheme for coalitional games, called coalition-flow networks (CF-NETs), where the formation of effective coalitions in a task-based setting is reduced to the problem of directing flow through a network. We show that our representation is intuitive, fully expressive, and captures certain patterns in a significantly more concise manner compared to the conventiona...

Coalitional games, including Coalition Structure Generation (CSG), have been attracting considerable attention from the AI research community. Traditionally, the input of a coalitional game is a black-box function called a characteristic function. Previous studies have found that many problems in coalitional games tend to be computationally intractable in this black-box function representation....

متن کاملOn agent types in coalition formation problems
Coalitions and cooperation are key topics in multi–agent systems (mas). They enable agents to achieve goals that they may not have been able to achieve independently. A range of previous studies have found that many problems in coalitional games tend to be computationally intractable that is, the computational complexity grows rapidly as a function of the number of participating agents. However...
متن کاملCore Membership Computation for Succinct Representations of Coalitional Games
In this paper, I compare and contrast two formal results on the computational complexity of core membership determination in two compact representations of coalitional games. Conitzer and Sandholm [1] proposed the multi-issue representations of coalitional games. This representation attempts to decompose a coalitional games into a set of sub-games. Later, Ieong and Shoham [3] proposed the margi...
