Agents
coexist in a shared environment and pursue their respective goals in the presence of
other agents. A collection of agents interacting with each other can be organized as
an agent group. We regard an agent group as the fundamental unit for the evolution
process. Users can organize agent groups in terms of their preferences or let agents
decide which groups they are willing to join. Thus, the criteria for group formation
can be varied, and agents in one group can be homogeneous or heterogeneous.
