Towards formal model of adversarial action in multi-agent systems

Detecting and preventing the adversarial action of an agent with respect to the community of agents can be a serious issue in the design of open multi-agent systems. This task is severely domain dependent and it is hard to find a general solution. This contribution presents a utility based model of adversarial action and analyses few properties of adversarial behavior in multi-agent systems. Potential use and important drawbacks of this model are discussed in the paper.
