pheromone. The collective behaviour that emerges is a form of autocatalytic behaviour — or allelomimesis — where the more are the ants following a trail, the more that trail becomes attractive for being followed. The process is thus characterized by a positive feedback loop, where the probability with which

these probabilities, we propose a global cost function that includes both global probability and path length. We show that the addition of a length term significantly improves trail finding ability. However, computing the optimal trail becomes intractable as known dynamic programming methods do not apply. Thus we

This paper describes a novel method of achieving load balancing in telecommunications networks. A simulated network models a typical distribution of calls between nodes; nodes carrying an excess of traffic can become congested, causing calls to be lost. In addition to calls, the network also

The notion of Erdős number has floated around the mathematical research community for more than thirty years, as a way to quantify the common knowledge that mathematical and scientific research has become a very collaborative process in the twentieth century, not an activity engaged in solely

c contains no PEC closed trails, we show that the problem of finding a PEC s-t trail visiting a given subset of vertices can be solved in polynomial time and prove that it becomes NP-complete if we are restricted to graphs with no PEC cycles. We also deal with graphs G c containing no (almost) PEC

Abstract. We present the first global simulations on the oc-currence of meteor trail plasma irregularities. These results seek to answer the following questions: when a meteoroid disintegrates in the atmosphere, will the resulting trail be-come plasma turbulent? What are the factors influencing

challenges before it becomes practical at large scale since trail-based navigation requires considerable storage and computational resources when carried out naively. In this position paper, we propose an architecture for a query engine for trails and associated discovery and ranking techniques that can

invited to recount stories of becoming an artist. In looking at this event I want to explore questions around the possibilities and limitations of narratives in microsociological inquiries. In following trails of ARENDT's theorisation of stories, I explore connections and tensions between

differential equa-tions are formulated for the density of the trails and for the number of individuals following trails or exploring randomly. It is assumed that the followers reinforce trails by pheromone marking, and that individuals respond to the strength of the trails by becoming more efficient followers

Trails have been identified as a useful mechanism to provide navigational assistance in ubiquitous computing environments. Indeed, trails provide within a single framework an effective way to record, structure and represent interactions between users and physical or digital resources. Yet
