The front cover of the current issue of the Journal of The Royal Society Interface(vol. 3, no. 7) features a picture of marked ants (Temnothorax albipennis) in a laboratory nest.
Recent experimental work conducted at Bristol University has demonstrated these ants use a collective decision-making mechanism that can compromise flexibly between speed and accuracy of decisions.
Research published in this issue examines the optimality of this trade-off under varying constraints, and considers its potential application to decentralised control problems in computer science.
