Emergence beyond consensus for multi-agent systems

摘要:

In this talk we discuss how to use tools such as non-cooperative differential games, optimal control and manifold theory to achieve emergence for a multi-agent system, in particular non-consensus emergence, which is clearly connected to Distributed Artificial Intelligence (DAI) since group intellectual behavior in DAI is based on individual intellectual behaviors. In many scenarios, agents in a MAS model can act cooperatively, competitively or exhibit neutral behaviors.To handle those complexities, it is very useful to characterize the invariances that define the emergence. Such emergence can be tightly connected to a Nash equilibrium, or rather to an invariant manifold of Nash equilibria. In this talk we will use some cases of study to illustrate our thoughts. We begin with crowd dynamics, then use Turing’s model for the diffusion of morphogens to explore its connection to emergence by self-organization, finally we will discuss emergence in a non-cooperative differential game framework in which emergence is achieved by Nash equilibrium strategies in an intrinsic way in the sense that they are only attributed to the inter-agent interaction and geometric properties of the network.
