A unified theory of underreaction, momentum trading and overreaction in asset markets
, 1999
"... We model a market populated by two groups of boundedly rational agents: “newswatchers” and “momentum traders.” Each newswatcher observes some private information, but fails to extract other newswatchers’ information from prices. If information diffuses gradually across the population, prices underre ..."

Formalising trust as a computational concept
, 1994
"... Trust is a judgement of unquestionable utility — as humans we use it every day of our lives. However, trust has suffered from an imperfect understanding, a plethora of definitions, and informal use in the literature and in everyday life. It is common to say “I trust you, ” but what does that mean? T ..."

Artificial Intelligence (DAI) is raised. The thesis presents a testbed populated by simple trusting agents which substantiates the utility of the formalism. The formalism provides a step in the direction of a proper understanding and definition of human trust. A contribution of the thesis is its detailed
Stability of Evolving Agent Populations
, 2007
"... Stability is perhaps the most desired feature in the systems that we design. It is important for us to be able to predict the response of a Multi-Agent System (MAS) to various environmental conditions prior to its actual deployment. The Chli-DeWilde agent stability measure views a MAS as a discrete ..."

, focusing on evolving agent populations. Additionally, using our extended agent stability measure, we construct an entropy-based definition for the degree of instability. An example system, the Digital Ecosystem, is considered in detail to investigate the stability of an evolving agent population through
Apoptosis: a Basic Biological Phenomenon with Wide-ranging Implications in Tissue Kinetics
- Br. J. Cancer
, 1972
"... Summary.-The term apoptosis is proposed for a hitherto little recognized mechanism of controlled cell deletion, which appears to play a complementary but opposite role to mitosis in the regulation of animal cell populations. Its morphological features suggest that it is an active, inherently program ..."

Measuring the information content of stock trades
- Journal of Finance
, 1991
"... This paper suggests that the interactions of security trades and quote revisions be modeled as a vector autoregressive system. Within this framework, a trade's information effect may be meaningfully measured as the ultimate price impact of the trade innovation. Estimates for a sample of NYSE is ..."

significant for smaller firms. CENTRALTO THE ANALYSIS of market microstructure is the notion that in a market with asymmetrically informed agents, trades convey information and therefore cause a persistent impact on the security price. The magnitude of the price effect for a given trade size is generally held
An Ecological Approach to Agent Population Management
"... The problem of maintaining a desired number of mobile agents on a network is not trivial, especially if what is re-quired is a completely decentralized solution. Decentralized control makes a system more robust and less susceptible to partial failures. The problem of agent population manage-ment is ..."

Agent populated active networks
- In The 2nd IEEE International Conference on Advanced Communication Technology (ICACT-2000), Muju (Korea
, 2000
"... Abstract Active networking aims at transforming passive data carriers to active, dynamically configurable machines that no only pass data to each other but also perform computation on those data. In such a framework mobile agents can help either as carriers of the active code to be installed on acti ..."

Developing Agents Populations with Ethogenetics

We propose therefore a novel evolutionary approach to design agent behaviors in situated MAS, called "Ethogenetics". We also describe ATNoSFERES, a f ..."

Investigations of the Dynamics of an Evolving Agent Population
- Life. University of Dortmund
, 1997
"... this paper we wish to present current research on the dynamics in an agent population acting in a 2-dimensional continuous virtual environment on which a Genetic Algorithm (GA) operates as evolution mechanism. We will give a compact description of the agent structure, of their control mechanism and ..."
