Negotiation tactics for autonomous agents

Autonomous agents are being increasingly used in a wide range of applications. The agents operate in common environments and, over time, conflicts inevitably occur among them. Negotiation is the predominant process for solving conflicts. Recent growing interest in electronic commerce has also given increased importance to negotiation. This paper presents a generic negotiation mechanism that handles multiparty, multi-issue and single or repeated rounds and introduces a set of negotiation tactics that express the initial attitude of the agents and generate counterproposals either by making or not making concessions.
