Abstract
This paper addresses qualitative and quantitative diversity and specialization issues in the frame-
work of self-organizing, distributed, arti cial systems. Both diversity and specialization are ob-
tained via distributed learning from initially homogeneous swarms. While measuring diversity
essentially quanti es di erences among the individuals, assessing the degree of specialization
implies to correlate the swarm's heterogeneity with its overall performance. Starting from a
stick-pulling experiment in collective robotics, a task that requires the collaboration of two ro-
bots, we abstract and generalize in simulation the task constraints to k robots collaborating
sequentially or in parallel. We investigate quantitatively the in uence of task constraints and
type of reinforcement signals on diversity and specialization in these collaborative experiments.
Results show that, though diversity is not explicitly rewarded in our learning algorithm and there
is no explicit communication among agents, the swarm becomes specialized after learning. The
degree of specialization is a ected strongly by environmental conditions and task constraints,
