      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 ...

      A cost mechanism for fair pricing of resource usage 

      Mavronicolas, Marios; Panagopoulou, P. N.; Spirakis, Paul G. (2005)
      We propose a simple and intuitive cost mechanism which assigns costs for the competitive usage of m resources by n selfish agents. Each agent has an individual demand

      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 ...

      Distributed function calculation via linear iterative strategies in the presence of malicious agents 

      Sundaram, S.; Hadjicostis, Christoforos N. (2011)
      Given a network of interconnected nodes, each with its own value (such as a measurement, position, vote, or other data), we develop a distributed strategy that enables some or all of the nodes to calculate any arbitrary ...

      Extended semantics and optimization algorithms for CP-networks 

      Brafman, R. I.; Dimopoulos, Yannis (2004)
      Preference elicitation is a serious bottleneck in many decision support applications and agent specification tasks. Ceteris paribus (CP)-nets were designed to make the process of preference elicitation simpler and more ...

      Extending SATPLAN to multiple agents 

      Dimopoulos, Yannis; Hashmi, M. A.; Moraïtis, Pavlos (2011)
      Multi-agent planning is a core issue in the multi-agent systems field. In this work we focus on the coordination of multiple agents in a setting where agents are able to achieve individual goals that may be either independent, ...

      Multi-agent coordination and cooperation through classical planning 

      Dimopoulos, Yannis; Moraïtis, Pavlos (2007)
      Multi-agent planning is a fundamental problem in multiagent systems that has acquired a variety of meanings in the relative literature. In this paper we focus on a setting where multiple agents with complementary capabilities ...

      Multiagent reinforcement learning: Spiking and nonspiking agents in the Iterated Prisoner's Dilemma 

      Vassiliades, Vassilis; Cleanthous, A.; Christodoulou, Chris C. (2011)
      This paper investigates multiagent reinforcement learning (MARL) in a general-sum game where the payoffs' structure is such that the agents are required to exploit each other in a way that benefits all agents. The contradictory ...
