We explicitly calculate the aggregate diffusion dynamics in one-dimensional agent-based models of adoption of new products, without using the mean-field approximation. We then introduce a clusters-dynamics approach, and use it to derive an analytic approximation of the aggregate diffusion dynamics in multidimensional agent-based models. The clusters-dynamics approximation shows that the aggrega...

Bi-lateral negotiations represent an important class of encounter in agent-based systems. To this end, this paper develops and evaluates a heuristic model that enables an agent to participate in multiple, concurrent bi-lateral encounters in competitive situations in which there is information uncertainty and deadlines.

In this paper we analyze some common simplifications present in the traditional AI / RL problems. We argue that only facing particular conditions, often avoided in the classic statements, will allow the overcoming of the actual limits of the science, and the achievement of new advances in respect to realistic scenarios. This paper does not propose any paradigmatic revolution, but it presents a ...

This paper provides a survey of existing research on agent-based approaches to transportation and traffic management. A framework for describing and assessing this work will be presented and systematically applied. We are mainly adopting a logistical perspective, thus focusing on freight transportation. However, when relevant, work of traffic and transport of people will be considered. A genera...

We built an agent-based model of political party competition in order to explore the effect of the decrease in the number of relevant political issues on the number of political parties and the corresponding voter shares. We find that, when the space experiences a political shock and suddenly reduces in the number of dimensions, the number of political parties declines. We also observe that, af...

There has recently been increasing interest in group decision making, and in particular the mechanisms through which a group of individuals can arrive at a consensus decision. In this paper we investigate the effects of resource availability upon consensus decision making in a primate group. We extend an existing agent-based model of primate decision making to incorporate a model of diminishing...

The EURACE project was one of the important research collaborations in the field of agent-based modeling of economic systems. Its target was to create an agent-based model and tools aimed at policy makers for use in macro-economic modelling and economic policy design at the European level. In this paper we report experiences and progress from the EURACE project, and summarize problems that need...
