Query: The Sharer's Dilemma in Collective Adaptive Systems of Self-Interested
  Agents   In collective adaptive systems (CAS), adaptation can be implemented by
optimization wrt. utility. Agents in a CAS may be self-interested, while their
utilities may depend on other agents' choices. Independent optimization of
agent utilities may yield poor individual and global reward due to locally
interfering individual preferences. Joint optimization may scale poorly, and is
impossible if agents cannot expose their preferences due to privacy or security
issues. In this paper, we study utility sharing for mitigating this issue.
Sharing utility with others may incentivize individuals to consider choices
that are locally suboptimal but increase global reward. We illustrate our
approach with a utility sharing variant of distributed cross entropy
optimization. Empirical results show that utility sharing increases expected
individual and global payoff in comparison to optimization without utility
sharing. We also investigate the effect of greedy defectors in a CAS of
sharing, self-interested agents. We observe that defection increases the mean
expected individual payoff at the expense of sharing individuals' payoff. We
empirically show that the choice between defection and sharing yields a
fundamental dilemma for self-interested agents in a CAS.
