Successful termination of many of these interactions is not achieved only via exchange of a series of single-message suggestions and requires that an arguer offer compelling justifications to prove his/her claim. Obviously, before negotiation is started, decision should be made about the terms and arguments that can convince the other side and terminate negotiations successfully. In other words, an exact plan of arguments and their order should be prepared. The same is true about a multi - agent environment where each agent needs planning and executing a sequence of actions to achieve its goals. Some actions in these sequences are under the direct control of the planner agent and others require negotiations with other agents. Negotiation is usually carried out during the plan execution, however, it can be considered during the planning stage, as in real life. In this paper, we present a new approach that takes into account incomplete information about opponent’s position in negotiation by using a nondeterministic planner with incomplete knowlage and sensing actions. We evaluate our approach by solving a well known negotiation scenario. %9 journal article %R 10.22436/jmcs.010.04.05 %U http://dx.doi.org/10.22436/jmcs.010.04.05 %P 266-274
