Problem with Beliefs
We study the online buyer coalition formation problem, which is a
natural e-commerce application for distributed agent technology, with
both B2B and B2C examples emerging. Most existing works in this
topic so far have treated it as a transferable utility problem with the
agent's preferences treated as common knowledge, and used social util-
ity as measurement of solution quality, whereas the more important
criterion of coalition stability is either not dealt with, or only handled
partially.
In this chapter, we develop a distributed non-transferable payoff
approach. We follow the mechanism design principle by providing a
stable and scalable mechanism and also propose strategies. We show
by experiment that, provided the proposed strategies are used by the
agents, the mechanism can reach b-core stable results in over 99% of
the test cases. We then show by separate experiment that it is indeed
advantageous for the agents to follow the proposed strategy.
