We investigate and discuss safety and privacy preserving properties of a game-theortic based coalition algorithm KCA for forming kernel stable coalitions among information agents in face of imperfect information on actual coalition values, and changing agent society. In addition, we analyze the chances of deceiving information agents to succeed in coalition(More)
A large variety of solutions exists for the problem of coalition formation among autonomous agents, at the theoretical level within game theory, and at the practical, algorithmic level, within multi-agent systems. However, one major underlying assumption of algorithmic solutions suggested to date is that the values of the coalitions are known and are(More)
We define <b>Trusted Kernel-based Coalition Formation</b> as a novel extension to the traditional kernel-based coalition formation process which ensures agents choose the most reliable coalition partners and are guaranteed to obtain the payment they deserve. To this end, we develop an encryption-based communication protocol and a payment scheme which ensure(More)
Cooperative autonomous agents form coalitions in order to share and combine resources and services to efficiently respond to market demands. With the variety of resources and services provided online today, there is a need for stable and flexible techniques to support the automation of agent coalition formation in this context. This paper describes an(More)
We propose a new low-complexity coalition forming algorithm , BSCA-F, that enables agents to negotiate bilateral Shapley value stable coalitions in uncertain environments, and demonstrate its usefulness by example. In particular, we show that utilizing the possibilistic mean value for de-fuzzifying negotiated fuzzy agent payoffs is reasonable, and fuzzy(More)
In this paper, we propose a coalition formation protocol, called BSCA-P, that allows intelligent agents to negotiate game-theoretically stable coalitions for Web service trading with a maximum of individual monetary profit, while keeping certain kinds of financial data private. We show that no agent has to reveal its local service sales value and final(More)
