Self-contained and unified in presentation, this helpful e-book presents a huge creation to the interesting topic of many-body collective platforms with adapting and evolving brokers. The insurance contains video game theoretic platforms, multi-agent structures, and large-scale socio-economic platforms of person optimizing brokers. the range and scope of such structures were gradually growing to be in laptop technology, economics, social sciences, physics, and biology.

We can also define a randomized joint strategy, which randomizes between pure joint strategies. When both agents choose mixed strategies, it is characterized as randomized joint strategies that randomize between pure joint strategies. Then, the question is whether we can find an efficient rule of the joint strategy choice that specifies a plan for each agent so that the Pareto-efficient outcome is obtained. We may need to find some mechanism for achieving Pareto-efficiency using, (1) an external device, such as signals, or an authorization device, or (2) learning.

When heterogeneity is significant, we need to be able to show the gains from heterogeneity. Introduction to Collective Systems 19 However, the analysis of a collective system of heterogeneous agents becomes difficult and is often intractable. Another interesting problem is that agents are very homogeneous in the beginning. Differences in behavior and strategy use evolve endogenously as the collective system runs. Agent heterogeneity becomes a changing feature of the collective systems that can then be studied.

Therefore, in order to investigate the performance of a collective system of adapting or evolving agents, we need to explore a new method beyond 26 Adaptation and Evolution in Collective Systems the conventional equilibrium analysis that emphasizes the dynamic and evolving aspects of the system. The priority for a desirable collective outcome is stability, which is to be crudely modeled using the idea of equilibrium of the system. However, the condition of stability is not enough, and we need other criteria, efficiency and equity.
