    In grid computing, agent-based load balancing is one of the most important problems. In this paper, we present a macroscopic model to describe the dynamics of agent-based load balancing with time delays. We concern the number and size of teams where tasks queue. The time gap, during which a single agent searches a suitable node and transfers a task to the node, is incorporated into balancing proce... View full abstract»

    Multi-agent interaction protocols are used to support extended conversations between interacting agents. Traditionally, agent interaction protocols have just specified the overt interactions that take place among communicating agents and have ignored other, non-interactive, events that may have a bearing on the ensuing conversation. In this paper we present our own approach for modelling interacti... View full abstract»

    Existing negotiation agents are primitive in terms of what they can learn and how responsive they are towards the changing negotiation contexts. These weaknesses can be alleviated if an expressive representation language is used to represent negotiation contexts and a sound inference mechanism is applied to reason about the preferential changes arising in these negotiation contexts.

    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»

    We consider the problem of searching a set of data repositories, each managed by an independent agent which is able to handle queries from users, as well as queries from peer agents. Given a query, an agent's task is to find a closest match to the query over all the distributed databases. The agents search the distributed databases cooperatively by routing queries with each other. However, it is i... View full abstract»

    This article presents a model for designing negotiation agent with two distinguishing features: 1) a market-driven strategy and 2) a set of relaxed decision rules. Market-driven agents make adjustable rates of concession by reacting to changing market situations. In determining the amount of concession for each negotiation round, a market-driven agent is guided by three mathematical functions of r... View full abstract»

    This paper describes a multi agent approach of the organisation of a collective activity within a pedagogical context. We consider pedagogical situations where learners have to explicitly define the articulation of their collective work and then achieve the different tasks they have defined. Our objective is to support them by taking in charge some of these tasks in a way that emphasizes an explic... View full abstract»

    A rapid growth of available geospatial data requires development of systems capable of autonomous data retrieval, integration and validation. Mobile agent technology may provide a suitable framework for developing such systems since this technology can deal, in a natural way, with the distributed heterogeneous nature of the data. We evaluate our novel multi-agent architecture for geospatial data i... View full abstract»

    Members of high-performing human teams can often anticipate information needs of teammates and offer relevant information to them proactively. Such capabilities are highly desirable for agent teams to achieve better teamwork processes for supporting information gathering, information fusion, and decision makings of teammates.

    Multi-item, multi-unit negotiations in industrial procurement pose serious challenges to buying agents when trying to determine the best set of providing agents' offers. Typically, a buying agent's decision involves a large variety of constraints that may involve attributes of separate items as well as attributes of different, multiple items. In this paper we present Ibundler, an agent-based servi... View full abstract»

    Elvin is a scalable and efficient publish-subscribe event notification system. We provide an interpretation, in terms of communicative acts of the Elvin messages that are used by mobile agents in order to utilize Elvin services. We provide a basis for integrating Elvin services within a multi-agent community, i.e. agents can interact with Elvin at the agent communication language level, and show h... View full abstract»

    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»

    The design of an agent system for robotics is a problem that involves aspects coming from many different disciplines (robotics, artificial intelligence, computer vision, software engineering). The most difficult part of it, often consists in producing and tuning the algorithms that incorporates the robot behavior (planning, obstacle avoidance,...) and abilities (vision, manipulation, navigation,.....

    We show how a goal-oriented view of mobile agent itineraries separates itinerary the agent must accomplish (which we call its ITAG-Goals) from the agent is to accomplish its goals (i.e., its strategies), thereby providing flexible and robust behavior in a dynamic network. Our approach generates strategies given a goal and a model of the network environment. We also show how strategies can be reuse... View full abstract»

    In this paper, we propose a novel multiagent learning approach, which is based on online analytical processing (OLAP) data mining. First, we describe a data cube OLAP architecture which facilitates effective storage and processing of the state information reported by agents. This way, the action of the other agent, even not in the visual environment of the agent under consideration, can simply be ... View full abstract»

    Air traffic management (ATM) involves collaborative work from several actors: traffic flow managers, air traffic controllers (controllers) and pilots. The ever-increasing demand for commercial air travel poses great challenges to today's airspace-centered ATM system in which each controller only undertakes the responsibility to control the aircraft flying through her/his own airspace (sector).

    This paper presents a hybrid architecture for autonomous robot navigation. It includes a deliberative layer that hierarchically extracts a global path from a geometrical-topological model of the environment. This path is decomposed into a set of partial goals. Then, a new case-based reasoning based reactive layer capable of learning new local navigation strategies moves from each partial goal to t... View full abstract»

    A novel method for asymmetric multiagent reinforcement learning is introduced in this paper. The method addresses the problem where the information states of the agents involved in the learning task are not equal; some agents (leaders) have information on how their opponents (followers) will select their actions and based on this information leaders encourage followers to select actions that lead ...

    Knowledge sharing is crucial to improve the performance of computationally limited agents with limited knowledge. In this paper, we investigate the long-term impact of knowledge sharing on the overall performance of a multi-agent system. In particular, we study the diffusion of knowledge by introducing a formal model. We also analyze the long run equilibrium of it through simulations. View full abstract»
