Jonny black: A mediating approach to multilateral negotiations

Abstract

We describe the strategy of our negotiating agent, “Jonny Black”, which received the 3rd place in ANAC 2015 competition in the “Nash Product” category. The agent tries to act as a mediator to find the best outcome for all the agents, including itself, in the negotiation scenario. The agent models other agents in the negotiation, and attempts to find the set of outcomes which are likely to be accepted by the other agents, and then picks the best offer from its own viewpoint.We give an overview of how to implement such a strategy and discuss its merits in the context of closed multilateral negotiation.
