Abstract
In this work, we study behavioural specialization in a swarm of autonomous robots. In the studied swarm, robots have to carry out tasks of different types that appear stochastically in time and space in a given environment. We consider a setting in which a robot working repeatedly on tasks of the same type improves its performance on them due to learning. Robots can exploit learning by adapting their task selection behaviour, that is, by selecting with higher probability tasks of the type on which they have improved their performance. This adaptation of behaviour is called behavioural specialization. We employ a simple task allocation strategy that allows a swarm of robots to behaviourally specialize. We study the influence of different environmental parameters on the performance of the swarm and show that the swarm can exploit learning successfully. However, there is a trade-off between the benefits and the costs of specialization. We study this trade-off in multiple experiments using different swarm sizes. Our experimental results indicate that spatiality has a major influence on the costs and benefits of specialization.
Keywords: specialization, task allocation, swarm robotics, swarm intelligence, self-organization, division of labor.

Experimental set 5: cost and benefits
Set 5: Q-Q Plots of performance
Figure s5.1: Example Q-Q Plot for distribution of performance measured in number of tasks completed, for different settings of the cost and benefit tradeoff (search time vs. task completion time), at the end of the experiment. Left: the greedy strategy. Right: The selective stategy. In both cases the performance is normally distributed.
