An Approach to Implementing A Threshold Adjusting Mechanism in Very Complex Negotiations : A Preliminary Result

In this paper, we propose a threshold adjusting mechanism in very complex negotiations among software agents. The proposed mechanism can facilitate agents to reach an agreement while keeping their private information as much as possible. Multi-issue negotiation protocols have been studied widely and represent a promising field since most negotiation problems in the real world involve interdependent multiple issues. We have proposed negotiation protocols where a bidding-based mechanism is used to find socialwelfare maximizing deals. The existing works have not yet concerned about agents’ private information. Such private information should be kept as much as possible in their negotiation. Thus, in this paper, we propose a new threshold adjusting mechanism in which agents who open their local information more than the others can persuade the others. The preliminary experimental results demonstrate that the threshold adjusting mechanism can reduce the amount of private information that is required for an agreement among agents.The original publication is available at JAIST Press http://www.jaist.ac.jp/library/jaist-press/index.htmlKICSS 2007 : The Second International Conference on Knowledge, Information and Creativity Support Systems : PROCEEDINGS OF THE CONFERENCE, November 5-7, 2007, [Ishikawa High-Tech Conference Center, Nomi, Ishikawa, JAPAN
