      Adaptive agent negotiation via argumentation 

      Kakas, Antonis C.; Moraïtis, Pavlos (2006)
      In this paper, we study how argumentation can be used as a basis for negotiation between autonomous agents, where negotiation strategies of the different parties are represented as argumentation theories within their ...

      Argumentation Based Decision Making for Autonomous Agents 

      Kakas, Antonis C.; Moraïtis, Pavlos (2003)
      This paper presents an argumentation based framework to support the decision making of an agent within a modular architecture for agents. The proposed argumentation framework is dynamic, with arguments and their strength ...

      Argumentation based modeling of decision aiding for autonomous agents 

      Dimopoulos, Yannis; Moraïtis, Pavlos; Tsoukiàs, A. (2004)
      Decision Aiding can be abstractly described as the process of assisting a user/client/decision maker by recommending possible courses of his action. This process has to be able to cope with incomplete and/or inconsistent ...

      Argumentative agent deliberation, roles and context 

      Kakas, Antonis C.; Moraïtis, Pavlos (2002)
      This paper presents an argumentation based framework to support an agent's deliberation process for drawing conclusions under a given policy. The argumentative policy of the agent is able to take into account the roles ...

      Argumentative alternating offers 

      Hadidi, N.; Dimopoulos, Yannis; Moraïtis, Pavlos (International Foundation for Autonomous Agents and Multiagent Systems (IFAAMAS), 2010)
      This paper presents an argumentative version of the well known alternating offers negotiation protocol. The negotiation mechanism is based on an abstract preference based argumentation framework where both epistcmic and ...

      Crafting the mind of prosocs agents 

      Bracciali, A.; Endriss, U.; Demetriou, Neophytos; Kakas, Antonis C.; Lu, W.; Stathis, Kostas (2006)
      PROSOCS agents are software agents that are built according to the KGP model of agency. KGP is used as a model for the mind of the agent, so that the agent can act autonomously using a collection of logic theories, providing ...

      Crowds by example 

      Lerner, A.; Chrysanthou, Yiorgos L.; Lischinski, D. (2007)
      We present an example-based crowd simulation technique. Most crowd simulation techniques assume that the behavior exhibited by each person in the crowd can be defined by a restricted set of rules. This assumption limits ...

      A distributed visualization system for crowd simulations 

      Vigueras, G.; Orduña, J. M.; Lozano, M.; Chrysanthou, Yiorgos L. (2011)
      The visualization system of large-scale crowd simulations should scale up with both the number of visuals (views of the virtual world) and the number of agents displayed in each visual. Otherwise, we could have large scale ...

      The KGP model of agency for Global Computing: Computational model and prototype implementation 

      Bracciali, A.; Demetriou, Neophytos; Endriss, U.; Kakas, Antonis C.; Lu, W.; Mancarella, P.; Sadri, F.; Stathis, Kostas; Terreni, G.; Toni, F. (2005)
      We present the computational counterpart of the KGP (Knowledge, Goals, Plan) declarative model of agency for Global Computing. In this context, a computational entity is seen as an agent developed using Computational Logic ...

      A performance analysis framework for mobile agent systems 

      Dikaiakos, Marios D.; Samaras, George S. (Springer Verlag, 2001)
      In this paper we propose a novel performance analysis ap- proach that can be used to gauge quantitatively the performance char- acteristics of different mobile-agent platforms. We materialize this ap- proach as a hierarchical ...

      Reasoning about actions and change in answer set programming 

      Dimopoulos, Yannis; Kakas, Antonis C.; Michael, Loizos (Springer Verlag, 2004)
      This paper studies computational issues related to the problem of reasoning about actions and change (RAC) by exploiting its link with the Answer Set Programming paradigm. It investigates how increasing the expressiveness ...

      A unified and general framework for argumentation-based negotiation 

      Amgoud, L.; Dimopoulos, Yannis; Moraïtis, Pavlos (2007)
      This paper proposes a unified and general framework for argumentation-based negotiation, in which the role of argumentation is formally analyzed. The framework makes it possible to study the outcomes of an argumentation-based ...
