Although an element is optional at the abstract level, it may be mandatory in a particular realization. That is, a realization may ...

Trading in financial markets is undergoing a radical transformation, one in which algorithmic methods are becoming increasingly more important. The development of intelligent agents that can act as autonomous traders seems like a logical step forward in this “algorithms arms race”. In this paper we describe an infrastructure for implementing hybrid intelligent agents with the ability to trade f...

Forty years ago, pioneers such as J.C.R. Licklider and Douglas Englebart championed the idea of interactive computing as a way of creating a “man-machine symbiosis” where mankind would be enabled to think in ways that were previously impossible [3, 5]. Unfortunately, in those times, such a mental coupling was limited to sitting in front of a terminal and keying in requests. Today, wearable comp...

In this article we propose a methodology for implementing the behaviour of intelligent interface agents using a BDI (Believes, Desires, Intentions) model. This work is based on the architecture presented in (Garijo et al. 98). We aim to show that BDI schemes applied to intelligent interface agents design produce robust and intuitively designed applications. This work has been applied to a fully...

An automated shopping framework which employs migrating agents as a means to implement today’s practices of online shopping is introduced. The system encompasses a new business market architecture which provides support for retailer agents and migrating shopper agents, with agent communication adhering to IEEE-FIPA specifications. The proposed system focuses on shopping input and protoco...

In modern computer games — like action, adventure, role-playing, strategy, simulation and sports games — artificial intelligence (AI) techniques play an important role. However, the requirements of such games are very different from those of the games normally studied in AI. This article discusses which approaches and fields of research are relevant to achieve a sophisticated goal-directed beha...

3 This paper considers the consequences of endowing an intelligent agent with the ability to modify its own code. The intelligent agent is patterned closely after AIXI with these specific assumptions: 1) The agent is allowed to arbitrarily modify its own inputs if it so chooses; 2) The agent’s code is a part of the environment and may be read and written by the environment. The first of these w...

NewsAgent is an intelligent type of agent that has the capability of generating personal newspapers from particular user preferences extracted by observation and feedback. This agent generates personal newspapers using static word analysis for extracting a global classification and case-based reasoning for dynamic subclassification. The agent observes users by an applet with capabilities of det...

This chapter aims to introduce the reader to the basic issues surrounding the design and implementation of intelligent agents. It begins by motivating the idea of an agent, presents a definition of agents and intelligent agents. The article then goes on to discuss four major approaches to building agents. First, logic based architectures are reviewed, in which decision-making is viewed as logic...

A taxonomic classification of multiagent systems is constructed based on how the agents share resources. A formal description of a single intelligent agent is considered first. A system of multiple intelligent agents is viewed, formally, as a collection of these single agents. Coupling between agents is defined as the degree to which agents share resources. By analyzing the coupling between the...
