The requesting (a) and accepting (b) activity of the human players by cluster size in different setups and the autonomous agents’ activity in setup D. All of the setups show a similar decay in activity, but it is notable that the players showed a more relaxed accepting activity in the setups with autonomous agents than in the setup with only human players. This behaviour can be result of the point based rewarding scheme as well as the performance of autonomous agents and their fully cooperative behaviour not resulting in sufficiently large clusters in the hybrid setups. As the autonomous agents were based on the same model, their activity is also represented in the setup D. The points are connected for visualizing the trends and the error bars represent standard error of the mean. (c) Overall activity per player in the experimental setups. Each marker represents the fraction of times when a player performed an action having the opportunity to request or accept in a particular setup. The distribution of the markers shows that none of the human players requested a swap in every opportunity they had. It is notable that in a few instances in setups A and B, the player accepted every incoming request.
