In this chapter, we conduct a comparative study of various traders following different trading strategies. We design an agent-based artificial stock market consisting of two opposing types of traders: “rational traders” (or “fundamentalists”) and “imitators” (or “chartists”). Rational traders trade by trying to optimize their short-term income. On the other hand, imitators trade by copying the ...

Although several approaches to the semantics of agent communication have been proposed, none of them is really suitable for dealing with agent autonomy, which is a decisive property of artificial agents. This paper introduces an observation-based approach to the semantics of agent communication, which combines benefits of the two most influential traditional approaches to agent communication se...

This paper describes a possible extension to the logical framework KARO to make it able to handle multiple agents. The KARO framework, which was initially developed by van der Hoek, van Linder and Meyer, makes use of epistemic and dynamic logics to express rational agents. These agents are capable of reasoning about their own actions and, somewhat limited, about the actions of other agents. Thi...

This paper focuses on the foundational role of interactive epistemology in the problem of generating plans for rational agents in multiagent settings. Interactive epistemology deals with the logic of knowledge and belief when there is more than one agent. In multiagent settings, we are interested in not only the agent’s knowledge of the state of the world, but also its belief over the other age...

Norms or conventions can be used as external correlating signals to promote coordination between rational agents and hence have merited in-depth study of the evolution and economics of norms both in the social sciences and in multiagent systems. While agent simulations can be used to gain a cursory idea of when and what norms can evolve, the estimations obtained by running simulations can be co...

Given common priors, no agent can publicly estimate a non-zero sign for the difference between his estimate and another agent’s future estimate. Thus rational agents cannot publicly anticipate the direction in which other agents will disagree with them.  2002 Elsevier Science B.V. All rights reserved.

We present a generic approach to the implementation of a principle stating that personality traits have an actual influence over the rational decision making process of cognitive agents. The contribution of this work concerns the coverage of the domain of psychology that is treated, the genericity of the proposal with regard to the models of rational agents used and above all, the improvement o...

Many tasks in day-to-day life involve interactions among several people. Many of these interactions involve negotiating over a desired outcome. Negotiation in and of itself is not an easy task, and it becomes more complex under conditions of incomplete information. For example, the parties do not know in advance the exact tradeoff of their counterparts between different outcomes. Furthermore in...
