    Following the view point of evolutionary dynamics, we have built a multi-agent system to study the emergence and disappearance of replicators in a heterogeneous network of resources. The class of systems we are looking at are systems facing structural uncertainties (supply structure and growth, concentration level, substitute products, etc.). In our 2002 approach, resources are modeled as strategi... View full abstract»

    The curves on well-logging parameter graph are very important to reservoir description. But how to keep the parameter graphs permanently and use the data implied in those curves efficiently are still open problems in petroleum industry. In this paper, we contribute an approach to digitizing well log curves and storing the digitized information into Oracle database or data file server with multi-ag... View full abstract»

    A suitable method for distributed transportation scheduling is necessary for the development of an agent-based logistics support system for the Australian Defence Force. Manager Agents (MA) require resources to be transported, in large quantities and on a global scale, using the services of many transport agents (TA). We investigate the application of K. Fischer et al.'s (1996) Extended Contract N... View full abstract»

    The winner determination problem (WDP) in combinatorial auctions is the problem of, given a finite set of combinatorial bids B, finding a feasible subset B' of B with a maximum revenue. WDP is known to be equivalent to the maximum weight set packing problem, and hard to approximate by polynomial time algorithms. This paper proposes three heuristic bid ordering schemes for solving WDP; the first tw... View full abstract»

    Based on our previous work on the formal specification language SLABS as well as a methodology and modelling language for modelling and specifying multi-agent systems, we further investigate how diagrammatic models of multi-agent systems can be used to derive formal specifications in SLABS. The modelling language is further developed by introducing behaviour diagrams and scenario diagrams for mode... View full abstract»

  • Living with dynamic concepts in dynamic environments: intelligent agents that adapt themselves

    Publication Year: 2003, Page(s):39 - 45
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (293 KB) | HTML iconHTML

    A dynamic perspective on concepts for intelligent agents is propagated. The discussion on the nature of concepts can be simplified to a dichotomy between objective/static and subjective/dynamic approaches. In the objective case, concepts are the same for all individuals. Under a dynamic perspective, concepts depend on different factors like the learning process, the environment, i.e. the situation... View full abstract»

    This paper defines an approach to simulation of natural systems, inspired by complex systems theory. A complex natural system is modeled as a multi-agent simulation system, agents representing living organisms, physical entities or environmental processes. Agents and their interactions can be aggregated to higher-level group agents. The properties and behavior of these group agents are determined ... View full abstract»

    Ant-based algorithms or ant colony optimization (ACO) algorithms have been applied successfully to combinatorial optimization problems. More recently, Parpinelli and colleagues applied ACO to data mining classification problems, where they introduced a classification algorithm called Ant/spl I.bar/Miner. In this paper, we present an improvement to Ant/spl I.bar/Miner (we call it Ant/spl I.bar/Mine... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (289 KB) | HTML iconHTML

    In this paper, we describe an approach by which one agent may infer the categorical preference structure of another agent in relation to a set of alternative proposals made in negotiation. The categorical preferences are inferred over a sequence of proposals, as preferences are disclosed one at a time. We seek to avoid strong ontological commitment between the agents, making only minimal assumptio... View full abstract»

    Flexibility and adaptability are essential properties of intelligent manufacturing systems. However, it is a major challenge to realize these properties and it is expensive to develop prototypes that are authentic and at the same time useful with respect to integration of state-of-the-art technologies in the area of agents and artificial intelligence. The use of cheap and flexible, yet realistic p... View full abstract»

    This paper describes a system, which has the capability to analyze and discover knowledge gathered from distributed sources. This autonomous system is implemented using the growing self organizing map (GSOM), which is a dynamic version of the self organizing map (SOM) and a multi agent communication system. The important contribution of this model is its ability to transfer local knowledge to a ce... View full abstract»

    In this paper, we present a coordination strategy using a hybrid negotiation mechanism for multi-agent systems. The particular application is distributed resource allocation among agents. Agents adaptively coordinate resource among themselves to handle possible resource shortage crises resulted from dynamic events they encounter in an uncertain environment. The hybrid negotiation mechanism combine... View full abstract»

    This paper introduces an integrative negotiation mechanism, which enables agents to choose any attitude from the extremes of self-interested and fully cooperative to those that are partially self-interested and partially cooperative. Experimental work verifies this mechanism and explores the question whether it always improves the social welfare to have an agent be completely cooperative. It is fo... View full abstract»

    Next generation of information systems will rely on cooperative intelligent agents for playing a fundamental role in actively searching and finding relevant information on behalf of their users in complex and open environments, such as the Internet. User interface agents (UIA) are semi-intelligent systems, which help the users to access, manage, share and exchange information. Recently, various re... View full abstract»

    The context of a statement or assertion can be critical to a useful understanding of its meaning. In huge knowledge bases such as the CYC project, capturing context explicitly encounters significant problems. Research at the Intelligent Agent Lab at The University of Melbourne has been investigating lightweight approaches to incorporating context in the construction of knowledge-based information ...

    In this paper, we present our notion of automatically assembling agents on-demand given high-level task descriptions. Our approach is based on the concept of the mission, which is represented by a hierarchical structure called the task decomposition diagram (TDD). Tasks in TDD are specified using a task specification language, which defines the functionality and possible implementation of those ta... View full abstract»

    In this paper, we propose a novel P2P cooperative proxy cache system using an individual-based model. We borrow the idea from an ecological system as well as economic systems to manage the cooperative proxies through data and information exchange among individual proxies. The data flow among proxy nodes creates artificial life for the cooperative proxies. The proxy servers with artificial life can... View full abstract»
