Our agent-related research spans the specification, design and implementation of agents, including agent architectures, logics and ontologies for agent-based systems, applications of agents (particularly in virtual environments), and software tools for building agents.

Agent architectures

We are currently working on the integration of reactive and deliberative behaviours in hybrid agent architectures through the generation and management of goals---how new goals are generated and how deliberative processes such as planning and problem-solving can be integrated into the architecture of an autonomous agent. This work has recently led to funding from Sony Computer Entertainment Europe for two PhD studentships in `Intelligent Agents for Believable Worlds'.

This research is part of a more general analysis of information processing models of mind in collaboration with researchers at the Universities of Birmingham and Notre Dame. Research questions here include: studies ofdeliberative and affective control in simple agent systems; requirements for architectures for human-like intelligent systems, particularly those that can account for qualia and emotions; explaining how such architectures develop and evolve; and deriving architecture-based systems of concepts of mental processes. This work is funded by a grant from the Leverhulme Trust.

Formal models of agent architectures

More recently we have begun to investigate formal models of agent architectures, including the space and time complexity of simple agent architectures and logics for resource bounded agents.

Applications of agents in virtual environments

In conjunction with the Communications Research Group at Nottingham, we are investigating the role of agents in controlling avatars in virtual environments inhabited by humans and other agents. Research questions include understanding social relationships and models of awareness in virtual environments, and issues of `adjustable autonomy' and delegation of control in human-agent interactions.

Another important strand of our agent research is tools for developing agents:

In collaboration with researchers at at the University of Birmingham, we are investigating the application of distributed event-based simulation techniques to the simulation of large-scale agent based systems consisting of many hundreds or thousands of agents. This work is funded by a grant from the EPSRC.

We are also working on extensions to the SIM_AGENT toolkit. The SIM_AGENT toolkit was developed at the University of Birmingham to facilitate the exploration of alternative agent architectures. Current work includes integrating SIM_AGENT with the MASSIVE-3 VR system developed at Nottingham and a distributed version of SIM_AGENT based on the HLA simulator interoperability framework.
