Multi-agent simulation was used to study the effect of simple models of leadership on interpersonal violence and warfare in small societies. Agents occupied a two dimensional landscape containing villages and food sources. Sharing and stealing contributed to normative reputation. Violence occurred during theft, in revenge killings, and in leader-directed warfare between groups. The simulations ...

Air quality is one of the main priorities for the improvement of the life quality in urban regions, as air pollution is usually, concentrated in such densely populated areas. Most of the countries have a national air quality monitoring network that allow an analysis of the air quality status, especially for urban regions that are nodes in this network. As the network is geographically distribut...

An agent-based model of population dynamics is presented. The model has as its expected behaviour the population dynamics of the equation-based Webworld model, within which large communities of species can be grown on evolutionary time scales. Such communities can be used in the agent-based model without disrupting the food web structure, and hence a unified model of evolutionary time and indiv...

This is a comprehensive summary paper of works done by the authors in 2004-7 but never published as a single narrative. Our works address various aspects of an Evolutionary Technology. We present the challenge, the approach (using simulated interactions from phenotype plasticity called ’fat interactions’) and the first results. On the road, we develop and test a platform for the general agent-b...

In this paper we use the Generalised Population Based Incremental Learning (GPBIL) in order to find profit-maximizing strategies for the Artificial Payment Card Market (APCM). The artificial market has modeled explicitly a multidimensional consumers’ and merchants’ demand for payment instruments. Given the complex shape of the demand, we have found that the GPBIL effectively explores the areas ...

The question “What drove foragers to farm?” has drawn answers from many different disciplines, often in the form of verbal models. Here, we take one such model, that of the ideal free distribution, and implement it as an agent-based computer simulation. Populations distribute themselves according to the marginal quality of different habitats, predicting settlement patterns and subsistence metho...

In this paper, we present a dynamic simulation model which projects the future population of the city of Leeds as a basis for policy analysis and scenario planning. We argue that microsimulation modelling is not entirely effective in the representation of student populations. Alternative approaches using both spatial interaction models and student agents are presented and evaluated. The results...

Because contemporary scientific research is conducted by groups of scientists, understanding scientific progress requires understanding this division of cognitive labor. We present a novel agent‐based model of scientific research in which scientists divide their labor to explore an unknown epistemic landscape. Scientists aim to find the most epistemically significant research approaches. We con...

In this paper we present an agent-based evacuation model which may be used to support private sector organizations with capabilities-based planning efforts surrounding likely terrorist attack scenarios. The model is distinguished by its explicit consideration of individuals with disabilities in respect to the characteristics influencing their ability to negotiate surroundings. The virtual envir...
