A macroscopic probabilistic model of adaptive foraging in swarm robotics systems (2009)
Presentation / Conference
Liu, W., & Winfield, A. F. (2009, February). A macroscopic probabilistic model of adaptive foraging in swarm robotics systems. Paper presented at 6th Vienna International Conference on Mathematical Modelling, Vienna

In this paper, we extend a macroscopic probabilistic model of a swarm of foraging robots from the homogeneous to the heterogeneous case. In the swarm, each robot is capable of adjusting its searching time and resting time thresholds following the rul...

Modelling a wireless connected swarm of mobile robots (2008)
Journal Article
Winfield, A. F., Liu, W., Nembrini, J., & Martinoli, A. (2008). Modelling a wireless connected swarm of mobile robots. Swarm Intelligence, 2(2-4), 241-266. https://doi.org/10.1007/s11721-008-0018-0

It is a characteristic of swarm robotics that modelling the overall swarm behaviour in terms of the low-level behaviours of individual robots is very difficult. Yet if swarm robotics is to make the transition from the laboratory to real-world enginee... Read More about Modelling a wireless connected swarm of mobile robots.

This article presents a simple adaptation mechanism to automatically adjust the ratio of foragers to resters (division of labor) in a swarm of foraging robots and hence maximize the net energy income to the swarm. Three adaptation rules are introduce... Read More about Towards energy optimization: Emergent task allocation in a swarm of foraging robots.

Towards the application of swarm intelligence in safety critical systems (2006)
